Axiota Animal Health Names Wamego as Global Headquarters

Fri, 03 Apr 2026 14:36:35 GMT

Axiota Animal Health, a global leader in cattle health solutions, announced it will name its facility in Wamego, Kan., as the company’s global headquarters.

The announcement formalizes the longstanding presence of Axiota Animal Health in Wamego, where the company operates manufacturing, research and development, and scientific operations for its products used by cattle producers in more than 30 countries worldwide.

“Wamego has long been a cornerstone of Axiota’s manufacturing and research, so designating it as our global headquarters is a natural next step,” says Bill Weldon, Axiota Animal Health CEO. “From here, we’re developing and producing technologies that help cattle producers around the world improve herd health and productivity. Leveraging our location within the KC Animal Health Corridor and our longstanding relationship with Kansas State University allows us to drive innovation and attract the top talent the industry demands.”

Located near K-State, the facility benefits from proximity to one of the nation’s leading veterinary and animal health research institutions. That connection helps Axiota attract specialized scientific talent and collaborate with researchers advancing the future of livestock health.

From its Wamego facility, Axiota supports cattle producers worldwide in improving herd health and performance through prevention-based, nonantibiotic solutions. This includes:

Lactipro , the only rumen-native probiotic that delivers Mega e, proven to promote rumen health and performance.
Multimin 90 (zinc, copper, manganese and selenium injection) is the only FDA-approved injectable supplement that delivers four trace minerals known to support cattle health and reproduction.

The decision highlights the global impact of the KC Animal Health Corridor , a hub stretching from Manhattan, Kan., to Columbia, Mo., with Kansas City at its heart. The region, home to the world’s largest concentration of animal health assets, serves as a leading center for life science research, development and collaboration.

“Axiota’s decision to locate its global headquarters in Wamego reflects the industry leadership that continues to define the corridor,” says Kimberly Young, president of the KC Animal Health Corridor. “Companies here aren’t just participating in the industry — they’re driving the science, technology and production that support animal health and food security around the world.”

Mystery Respiratory Virus in Texas Panhandle Feedlots Is Fake News

Tue, 17 Mar 2026 16:10:35 GMT

Tuesday morning, false information about a mystery respiratory virus in Texas Panhandle feedlots was circulating online. According to the Texas Animal Health Commission (TAHC) and Texas Cattle Feeders Association (TCFA), these claims are false.

Dr. Bud Dinges, TAHC executive director and Texas state veterinarian, says, “Texas animal health officials have confirmed with Amarillo region staff and partners at USDA Animal Plant and Health Inspection, Texas A&M Veterinary Medical Diagnostic Laboratory and Texas Cattle Feeders Association that no reports of cattle with an ‘unknown’ respiratory virus in the Texas Panhandle have been received and no regulatory action is being taken at this time.”

National Cattlemen’s Beef Association CEO Colin Woodall addressed the rumors issuing a strongly worded release:

“Spreading unverified information like this is not only irresponsible, it is harmful to cattle producers, the beef supply chain and consumer confidence in a safe and wholesome product. Our industry depends on transparency, science-based animal health protocols, and strong collaboration with state and federal animal health authorities. We encourage everyone — producers, media and the public — to rely on credible sources and verified information. NCBA and state affiliate partners will continue working closely with animal health officials to monitor any legitimate concerns and ensure the continued health of the U.S. cattle herd.”

The 3-Year Bet: Navigating Semen Choices and Herd Dynamics

Thu, 05 Feb 2026 15:54:07 GMT

In the high-stakes world of dairy management, a single decision made in the breeding lane can echo through a farm’s balance sheet for years. When a producer stands with a straw of semen in hand, they aren’t just breeding a cow; they are making a three-year financial and biological investment.

On a recent episode of the “Dairy Health Blackbelt Podcast,” Daryl Nydam, a professor of dairy health and production at Cornell University, sat down with Craig McConnel, an associate professor and director of veterinary medicine extension at Washington State University’s College of Veterinary Medicine , to discuss the complex intersection of herd dynamics, semen selection and long-term sustainability. Nydam’s message to producers is clear: While short-term cash flow is tempting, the long-term health of the dairy depends on maintaining the right number of replacements to ensure every stall is occupied by an efficient animal.

3-Year Investment Cycle

The fundamental challenge of replacement planning is the significant lead time required to bring a new animal into the milking string. As Nydam points out, a breeding decision made today involves a nine-month gestation period followed by approximately two years of growth before that animal begins producing milk.

“It’s really hard to predict your replacement needs three years forward,” Nydam explains. “Are we going to invest in sexed semen so we have enough replacements in three years, or are we going to try to shortcut that for quick cash flow?”

This shortcut usually involves breeding dairy cows to beef bulls to produce a high-value crossbred calf. While this provides an immediate sizable check at the farm gate, it reduces the pool of future replacements, effectively locking the producer into their current herd structure for years to come.

The ‘Black Calf’ Bubble

The rise of the beef-on-dairy market has fundamentally shifted the math for many producers. What began as a $500 premium for a crossbred calf has climbed to $750, then $1,000 and even higher in some regions.

“I don’t know where this bubble is going to go, but those things markedly influence herd replacement rates and therefore the dynamics of the herd,” Nydam says.

The temptation of immediate cash can lead to overbreeding to beef. When producers curtail their replacement pipeline to capture calf checks, they lose their most important management tool: the ability to cull. Nydam argues that if you don’t have an available heifer, you cannot make the most efficient cow-by-cow decisions; you are forced to keep underperforming or unhealthy cows simply to keep the stalls full.

The Culling Conundrum

From a veterinary perspective, culling is often seen through the lens of health: replacing a cow because she is sick or open. However, Nydam encourages a more management-centric view.

“If you show up on any dairy on any day, can you find one cow that you would like to replace that day?” Nydam says. “It’s really rare that I go to a dairy and say there are no cows here that I want to replace today.”

The ability to act on that instinct depends entirely on having a heifer ready to calve. As Nydam puts it: “A sick cow today doesn’t cause a heifer to calve two years ago.” If the replacement wasn’t planned for 36 months in advance, the producer is stuck with the “40-pound cow” that is dragging down the herd’s average efficiency.

Sustainability and the ‘Maintenance Dilution’

Beyond the immediate economics, the balance of replacements has a significant impact on a farm’s environmental footprint. Sustainability in dairy is largely a game of diluting maintenance costs.

A lactating cow requires a significant amount of energy and dry-matter intake just to maintain her body before she produces a single drop of milk. High-producing, efficient cows dilute that maintenance tax over a larger volume of milk.

“Having a few extra heifers is actually less resource-intensive versus not having the most efficiently productive lactating cows,” Nydam says. He adds that while a yearling heifer eats 20-25 lb. of dry matter, a lactating cow eats 55-60 lb. Keeping an inefficient cow because you lack a replacement heifer is a far greater waste of resources than raising a small surplus of heifers to ensure only the best cows remain in the herd.

Balancing Cash Flow with Strategy

Nydam acknowledges that “cash is king” and the revenue from crossbred calves is a vital part of the modern dairy business model. However, he cautions against sacrificing long-term profitability for short-term liquidity.

The goal for 2026 and beyond should be a strategic middle ground. By using tools to predict future replacement needs and understanding the marginal milk value required to offset a beef-cross calf check, producers can fine-tune their herd structure.

Ultimately, long-term sustainability is about having the most efficient animal in every slot on the dairy, all the time. Achieving that requires looking past today’s calf check and planning for the milk check of 2028.

Idaho’s $4 Billion Dairy Boom: Why the Gem State is Defying West Coast Trends

Tue, 03 Feb 2026 14:38:52 GMT

While milk production across the West Coast faces a period of contraction, Idaho is carving out a different narrative. With USDA reporting the state’s production value near $4 billion in 2024, Idaho has transitioned from a regional player into a global dairy powerhouse. According to Rick Naerebout, chief executive officer of the Idaho Dairymen’s Association, this surge isn’t accidental. It is the result of a unique confluence of business-friendly policy, aggressive vertical integration and a fundamental shift in how dairy cattle are valued.

A Surge on a Massive Base

The sheer scale of Idaho’s recent growth is impressive. Naerebout reports the state has seen consistent growth rates of 5% to 8% per month year-over-year for the last 15 months. For 2025, Idaho is projected to be up 7.5% in total milk production.

“That 7.5% is on a very big base,” Naerebout explains. “It equates to roughly 3.5 million pounds of milk a day more this year than we had last year. We’ve definitely turned on the milk production.”

This growth has been facilitated by two primary catalysts. First, Idaho’s dairy producers are entering the current economic downturn with exceptionally healthy balance sheets following strong financial performances in 2024 and early 2025. Second, and perhaps most importantly, regional processors have finally lifted base restrictions that limited producers to fractional growth for years. With those caps removed, the Idaho dairy industry has surged to meet the available capacity.

The Magic Valley: The Heart of the Industry

The epicenter of this expansion remains the Magic Valley. While growth is visible across the state, approximately 75% of Idaho’s dairy industry is concentrated in this region. The concentration allows for an infrastructure of scale that is difficult to replicate elsewhere.

Idaho’s operations are notably larger than the national average, boasting nearly 2,500 cows per dairy. This scale, combined with a business-friendly climate — including the absence of agricultural overtime pay — allows Idaho producers to maintain lower costs than their neighbors in California or Washington.

Components and the “Black Calf” Phenomenon

Interestingly, the growth isn’t just coming from more cows; it’s coming from “better” milk. According to Naerebout, while volume is up 7.5%, the increase in milk components means the actual yield for processors is closer to 9%. This allows plants to produce more cheese, butter and powder for every pound of milk delivered.

Producers in Idaho, like other states, are also shifting culling practices.

“We’re hanging onto cows because they’ve got a black calf in them, and that calf is worth roughly $1,500,” Naerebout says.

The beef-on-dairy trend has become ubiquitous in Idaho, with adoption rates significantly higher than the national average of 70%. For many Idaho producers, the day-old calf has become a high-value commodity that provides immediate cash flow with minimal risk, as many are partnered with large feedlot operators, like Simplot, or feedlots to take the animals immediately.

Resilience Through Risk Management

The dairy industry is notoriously volatile, yet Idaho has shown remarkable resilience. Over the last 30 years, the state has only seen negative growth twice: in 2009 and 2013. Naerebout attributes this to a sophisticated approach to business that sets Idaho producers apart.

“Our dairymen are very savvy businessmen,” he notes. “We have a higher-than-average use of hedging tools. They insulate themselves from market downturns by making sure they are hedged.”

This financial discipline, coupled with being well-capitalized, allows these large-scale operations to weather economic storms that might shutter smaller farms in other regions.

The Shift to Vertical Integration

Perhaps the most significant structural change in Idaho’s dairy landscape is the move toward vertical integration. Unlike the traditional cooperative structure involving hundreds of members, Idaho has seen the rise of “processor-producers.”

Facilities like Idaho Milk Products and High Desert Milk were founded by small groups of dairy families — sometimes fewer than six — who pooled their capital to build their own processing plants. While Naerebout describes the startup phase of these ventures as “absolute hell” where families nearly lost everything, those who survived are now capturing the margins that previously went to third-party processors.

“They are capturing more margin for their business and using it as a form of risk mitigation,” Naerebout says.

This evolution from simple milk producers to sophisticated industrial processors represents the future of the Idaho dairy model.

Looking Ahead

As the industry faces a tightening economic window, Idaho’s producers remain focused on the long term. The goal for many is not just survival, but the creation of viable, multi-generational businesses. By combining aggressive adoption of technology, sophisticated risk management, and a willingness to invest in the processing side of the value chain, Idaho is proving that even in a mature industry, there is still significant room for a “growth state” to thrive.

“Idaho has been, and will likely remain, a growth area for plants and processors alike,” says Phil Plourd, president of Ever.Ag Insights. “It’s a hospital environment where all the stakeholders seem aligned around growing the industry.”

With strong components, high-value beef-on-dairy calves and a business environment that rewards scale, Idaho is well-positioned to remain the cornerstone of Western dairy production for the foreseeable future.

New Leadership to Take on Key Animal Health Roles at USDA

Tue, 13 Jan 2026 19:23:03 GMT

USDA announced major leadership changes within the Animal and Plant Health Inspection Service (APHIS). Michael Watson, APHIS administrator, will retire at the end of January after decades of distinguished service, and Rosemary Sifford, deputy administrator for veterinary services and U.S. chief veterinary officer, has also retired from federal service after a similarly notable career.

Dedicated Public Servants

Watson’s notable career reflects his unwavering commitment to safeguarding U.S. agriculture, building strong partnerships with states and stakeholders and mentoring future leaders. Beginning his USDA career in 1994 as a plant pathologist with the Agricultural Research Service, he later held key leadership roles across multiple APHIS programs. APHIS says Watson consistently championed science-based policy, ensuring APHIS decisions were grounded in rigorous data and research to protect U.S. agriculture and maintain public trust. His legacy is one of collaboration, integrity and dedication to public service.

Sifford began her USDA career in 1997 as a Saul T. Wilson Scholar and held numerous roles across APHIS. Under her leadership and guidance, APHIS advanced major animal health efforts, including combatting highly pathogenic avian influenza — with unprecedented detections in dairy cattle — and strengthening preparedness and response for New World screwworm. APHIS says her direction ensured these efforts were grounded in science-based policy, supported by field-ready guidance, and delivered with transparent stakeholder engagement. A steadfast champion of practical, proven biosecurity, she worked hard to protect animal health nationwide.

“Dr. Watson and Dr. Sifford are dedicated public servants and we greatly appreciate their time at USDA, serving American farmers and ranchers, and protecting the national security of the U.S. I am so grateful for their extended service to support the Trump administration during such a critical time for American agriculture,” says U.S. Secretary of Agriculture Brooke L. Rollins in a news release. “The team at APHIS plays a critical role in protecting our food supply from foreign pests like the New World screwworm, as well as fighting diseases like bird flu. I have the utmost confidence in Ms. Moore, Dr. Huddleston and Dr. Dijab in continuing this critical mission and defending American agriculture.”

New Leadership

Starting Feb. 1, Kelly Moore will serve as acting administrator. Moore is currently acting chief operating officer for USDA’s marketing and regulatory programs mission area, and acting deputy administrator of marketing and regulatory programs business services.

“She brings extensive operational leadership experience and results-driven management, including a strong foundation of discipline from her prior service in the U.S. Marine Corps,” APHIS reports. “Ms. Moore is highly adept at guiding organizations through periods of change and transition and driving efficiency, compliance and innovation at scale — critical to APHIS’s mission during this pivotal time.”

Effective immediately, Dr. Alan Huddleston will serve as acting U.S. chief veterinary officer. With deep expertise in epidemiology and program development, he will represent U.S. animal health priorities internationally and maintain strong engagement with states and industry.

(USDA APHIS)

Dudley Hoskins, under secretary for marketing and regulatory programs, says their leadership and commitment to collaboration strengthened APHIS and the nation’s animal and plant health systems.

“These are consequential changes at a pivotal moment for the agency, and I am confident that Ms. Moore, Dr. Huddleston, and Dr. Dijab will not only serve as steady hands for program continuity but will lead APHIS into a new era,” Hoskins says.

To ensure continuity during this transition, APHIS veterinary services associate deputy administrator Adis Dijab will continue to provide operational oversight of veterinary services.

“APHIS operations continue uninterrupted, guided by science-based policies, strong stakeholder engagement and experienced acting leaders to ensure program continuity,” APHIS reports. “APHIS remains steadfast in its mission to protect the health, welfare and value of our Nation’s plants, animals, and natural resources — continuing to deliver solutions and essential services that safeguard U.S. agriculture and support stakeholders nationwide.”

FDA Report Shows 16% Increase in Livestock Antimicrobial Sales in 2024

Thu, 08 Jan 2026 21:38:20 GMT

After years of relative stability, U.S. antimicrobial sales for food-producing animals rose in 2024. According to the FDA’s 2024 Summary Report on Antimicrobials Sold or Distributed for Use in Food-Producing Animals , sales of medically important antibiotics increased 16% compared with 2023, marking a notable reversal after nearly a decade of plateauing or declining volumes.

When it comes to cattle, this report raises an important question: Does this increase reflect a temporary response to disease and production pressures, or does it reflect a more durable change in antimicrobial purchasing patterns?

FDA Antimicrobial Sales Trends Show a Clear Rebound

FDA data shows antimicrobial sales for food-producing animals peaked in 2015, followed by sustained declines after growth-promotion indications were removed and veterinary oversight expanded. From 2016 through 2023, total sales largely stabilized or declined modestly, including a 2% decrease from 2022 to 2023.

(FDA)

This pattern changed in 2024. Total antimicrobial sales increased 16% year over year, representing the largest single-year increase since regulatory reforms took effect. While overall volumes remain approximately 27% below 2015 levels, the size and rebound stands out against nearly a decade of gradual reduction.

Which antimicrobial classes increased in 2024?

The 2024 increase was not evenly distributed across antimicrobial classes. Several medically important categories accounted for most of the growth:

Tetracyclines: ~20% increase; remains the largest class by volume
Aminoglycosides: ~37% increase
Lincosamides: ~11% increase

In contrast, penicillins declined by approximately 14%, despite remaining among the most commonly sold classes overall.

The concurrent rise across these classes likely reflects increased disease pressure and production challenges. While FDA sales data cannot identify clinical drivers, the pattern points toward greater reliance on core therapeutic drugs during a challenging production year.

Looking across species, 41% of medically important antimicrobial sales in 2024 were intended for cattle, 43% for swine, and 16% for poultry.

What the Data Show for Cattle

When looking specifically at cattle, tetracycline sales increased ~19%, aminoglycosides increased ~38%, sulfonamides increased ~24% and cephalosporins increased ~26%.

These antimicrobial classes are foundational tools in cattle medicine, particularly for respiratory and systemic disease. Tetracyclines are widely used across beef and dairy systems for bovine respiratory disease, anaplasmosis and reproductive tract infections, supported by broad-spectrum activity, multiple formulations and long-standing familiarity in practice. Aminoglycosides are used more selectively but are important for treating gram-negative and enteric infections, often in more severe cases. Lincosamides are commonly used for respiratory disease and certain anaerobic or foot infections.

To provide additional context, the FDA report also includes biomass-adjusted antimicrobial sales, including an interactive dashboard , which accounts for changes in animal population size and average live weight. This data could be a more meaningful indicator of antimicrobial use intensity.

Biomass-adjusted sales of aminoglycosides, amphenicols, cephalosporins, fluoroquinolones, lincosamides, sulfonamides and tetracyclines for cattle all increased from 2023 to 2024 representing a higher intensity of use.

Swine Data Also Showed Increases

The sale of medically important microbial drugs for use in swine increased 13% from 2023 to 2024. While annual sales for swine have been slowly increasing since 2020, this jump is much larger than it has been in previous years.

Looking at specific drug classes, Aminoglycoside sales increased ~25%, fluoroquinolones increased ~49%, sulfonamides increased ~15%, tetracyclines increased ~15%, and lincosamides increased ~13%.

In swine, aminoglycosides and sulfonamides are frequently used to manage enteric and respiratory conditions. Fluoroquinolones and tetracyclines are critical for addressing complex swine respiratory diseases and systemic infections, while lincosamides are often specifically targeted at combating swine dysentery, mycoplasmal pneumonia and infectious arthritis.

Biomass-adjusted sales of these drugs for swine all also increased from 2023 to 2024.

Sales Data are not the same as on-farm use

A critical point emphasized by FDA is sales and distribution data do not directly measure the actual use of antimicrobial drugs on farms. These drugs can be purchased in anticipation of use, be used at a later date or held in inventory for future needs. There is no national system in place that measures antimicrobial use across animal production sectors in real time. Year-to-year fluctuations in sales can reflect many factors including animal health needs, changes in livestock populations and evolving production practices.

Despite the rebound in 2024, food-animal antimicrobial sales remain significantly lower than a decade ago. Even so, the data reinforce the need for stewardship that balances effective disease control with antimicrobial resistance considerations, guided by clinical judgment and herd-level decision-making.

How USDA and Veterinary Schools are Rebuilding the Rural Animal Health Pipeline

Mon, 22 Dec 2025 18:30:42 GMT

When the U.S. Secretary of Agriculture Brook Rollins formally elevated the rural veterinary shortage to a national priority on Sept. 19 , it marked a shift from long-standing concern to coordinated action. Since that announcement, a wave of federal initiatives, state investments and veterinary school-led programs has begun reshaping how the profession approaches rural workforce development, moving beyond loan repayment alone toward structural, pipeline-based solutions.

The announcement, introducing USDA’s Rural Veterinary Action Plan , acknowledges what producers and veterinarians have long warned: Insufficient access to food-animal and rural veterinary care poses risks to animal health, biosecurity and food system stability. USDA committed to expanding incentives, streamlining grant programs and actively engaging veterinary schools as workforce partners rather than passive beneficiaries.

Since then, USDA NIFA (National Institute of Food and Agriculture) has announced an investment of $3.8 million in the Veterinary Services Grant Program (VSGP) to mitigate food animal veterinary shortages. This investment was divided into 22 VSGP awards including eight Education, Extension, and Training (EET) grants and 14 Rural Practice Enhancement (RPT) grants. The complete list of awardees can be found here.

Innovative Training: How Veterinary Schools Are Closing the Gap

The EET awarded schools have not hesitated in taking action on their proposed strategies to improve and support rural veterinary education.

Texas Tech University’s School of Veterinary Medicine is creating the school’s first food animal residency program , planned to launch in 2026. This program will recruit early-career veterinarians to provide them with advanced clinical and research training to help them become future educators in food animal medicine. It is the hope that veterinarians trained through this residency will work to influence more students to pursue careers in food animal, large animal or mixed animal practice.

“This residency program is transformative for our school and the cattle industry,” says Guy Loneragan, dean of the School of Veterinary Medicine. “A capstone professional achievement for the residents in this program is attainment of diplomate status in the American Board of Veterinary Practitioners. This is a national recognition as an elite specialist in all things cattle. The residents will provide leadership to advance livestock health and protect the national interest in U.S. food production.”

Colorado State University will be amping up their existing virtual reality (VR) offerings , implementing livestock focused VR education into the curricula. The project will design and evaluate game-like VR modules where students can practice biosecurity, infection prevention and farm management.

The University of Alaska plans to enhance local access to scientific resources that support livestock production through updated veterinary instruction to increase student comfort with livestock medicine and increased Extension resources supporting livestock producers of Alaska. These resources will uniquely focus on supporting care for the local reindeer industry.

The Veterinary Diagnostic Laboratory (VDL) of the College of Veterinary Medicine at Iowa State University (ISU) has used the funding to open a new anatomical pathology residency program addressing the national shortage of veterinary pathologists.

“The ISU VDL is uniquely positioned to offer this training given our high caseload in swine, poultry and bovine relative to most traditional anatomic pathology residencies,” says Dr. Eric Burrough, professor of veterinary diagnostic and production animal medicine.

The University of Kentucky and the Auburn College of Veterinary Medicine are collaborating to address the Alabama-Kentucky specific shortage of rural veterinarians. Together, they aim to recruit students from USDA identified shortage counties and rural leadership and mentorship opportunities for upper-year veterinary students.

State-Led Initiatives and Regional Partnerships

Outside of these grants, Ohio State University’s College of Veterinary Medicine has launched the Protect One Health in Ohio initiative (Protect OHIO) . This initiative, supported by a $30-million investment from the state, centers around enrolling more students from Ohio’s rural communities, mentoring large animal and rural veterinarians and expanding risk assessment and surveillance programs for the state.

“Feeding people is a shared responsibility and it starts with healthy animals, resilient communities and a strong veterinary workforce,” says Leah Dorman, director of Protect OHIO. “This work is deeply personal to me. I’ve spent my career listening to rural voices, mentoring passionate students and building trust with Ohio’s agricultural and veterinary communities.”

Meanwhile, Wisconsin lawmakers have proposed a student loan relief bill granting veterinarians who have graduated within the past seven years $25,000 in student loan repayment for each year that they practice in a rural county (up to four years). Applicants would need to spend 25% of their time working with farm animals.

New Mexico has also offered loan relief for rural veterinarians . The Veterinary Medicine Loan Repayment Program, signed into law this year by Governor Michelle Lujan Grisham, offers up to $80,000 in debt relief to veterinarians who commit to working in underserved areas for at least four years.

The University of Nebraska-Lincoln, in partnership with Gov. Jim Pillen and state leaders, has launched the Elite 11 Production Animal Health Scholarship Program . This program allows 20 incoming freshman students who have identified that they want to go down the path of veterinary practice in rural Nebraska with production animals to receive scholarships covering 50% of their tuition. After that, 11 students in their junior and senior years will receive full tuition scholarships.

From Recruitment to Long-Term Retention

Four months after the initial announcement, the response to the rural veterinary shortage looks less fragmented and more intentional. Federal incentives, state investments and veterinary school-led training pipelines are beginning to align around a shared goal: making rural practice viable, visible and sustainable. The challenge is now execution; ensuring these programs translate into long-term retention, not just short-term recruitment.

First Case of Avian Flu Detected in Wisconsin Dairy Herd

Sun, 14 Dec 2025 21:35:02 GMT

A case of highly pathogenic avian influenza (HPAI) has been detected in a dairy herd in Dodge County, Wisconsin, the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) announced Sunday. This marks the first confirmed detection of the virus in dairy cattle in the state.

The herd was identified through routine National Milk Testing Strategy screening, not the surveillance required for moving cattle across state lines. The affected farm has been quarantined, and any cattle showing signs of illness are being separated for treatment.

Bird flu has already been detected in poultry flocks in Wisconsin. On Dec. 9, state officials reported HPAI in a flock in Marquette County, which is just one county away from the affected dairy herd.

HPAI in dairy cattle has been documented in the U.S. before, with the first detections reported in March 2024 in dairy herds in Texas and Kansas. Since then, there have been more than 1,000 confirmed cases across 18 states, primarily through targeted testing and monitoring programs. While the pace of new detections has slowed in recent months, one additional confirmed case has been reported in California within the past 30 days, indicating the virus is still a threat.

A Wake-Up Call for Dairy Biosecurity

The Wisconsin case comes as new research from Farm Journal highlights ongoing gaps in dairy biosecurity practices nationwide. A survey of more than 300 dairy producers, presented at the MILK Business Conference, found that while many operations report having biosecurity plans in place, consistent implementation and regular review remain a challenge.

According to the survey, 68% of farms with at least 250 cows say they have a biosecurity plan, yet 34% of those producers acknowledge they do not routinely review or update it. The findings point to vulnerabilities at a time when disease threats such as HPAI, New World screwworm and bovine spongiform encephalopathy continue to raise concern across the livestock sector.

(Farm Journal)

“We need biosecurity efforts to be more impactful at the ground level,” said Kirk Ramsey, professional services veterinarian with Neogen, who reviewed the survey results. “Not only to prevent major outbreaks, but also to protect employees and families from what could be carried home every day.”

As emerging diseases continue to challenge dairy operations, the research reinforces the importance of consistent, practical biosecurity measures to reduce risk and protect herd health.

What are the Symptoms of HPAI in Dairy Cattle?

As monitoring continues, officials are urging producers to stay alert for early signs of illness within their herds, as prompt detection and response remain key to limiting further spread. Signs of HPAI include:

Drop in milk production
Loss of appetite
Changes in manure consistency
Thickened or colostrum-like milk
Low-grade fever

State officials are monitoring the situation and working closely with the farm to contain the virus and prevent further spread. DATCP emphasized there is no concern for the safety of the commercial milk supply, as pasteurization eliminates the virus. The CDC considers the human health risk low.

Elanco Animal Health Shifts Focus to U.S., Redefining Livestock R&D and Manufacturing

Wed, 10 Dec 2025 23:55:59 GMT

Elanco Animal Health is restructuring its global operations, shifting investment toward the U.S., while reducing parts of its overseas footprint. During its 2025 Investor Day , the company announced plans to close its German animal health R&D facility and implemented targeted reductions to parts of its manufacturing workforce. Elanco plans to boost investment in U.S.-based innovation and manufacturing, pointing to greater clarity around tariffs and accelerated USDA regulatory times central factors.

“We made some big announcements,” says Jeff Simmons, Elanco CEO. “We rolled out a very strong growth agenda. A portfolio of historical innovation serving farmers, veterinarians, pet owners, livestock and industry. And it really leads to this growth agenda: a $400 million investment in American manufacturing and R&D.”

Consolidation Abroad, Investment at Home

As part of the restructuring, Elanco will shut down its German R&D site and reduce certain manufacturing operations abroad. According to the company, these actions are designed to streamline operations and consolidate resources where regulatory processes and market access are more predictable. At the same time, Elanco is redirecting capital toward its Innovation Laboratories at the company’s Indiana headquarters, a move intended to bring discovery, development and regulatory preparation under a unified roof.

For livestock veterinarians and producers, this consolidation could translate into more efficient development and approval of animal-health products. Shorter regulatory lead times and centralized R&D could improve the company’s ability to respond to evolving disease threats and to deliver vaccines, biologics or therapeutics in a more timely and consistent manner.

“Elanco is focused on delivering innovation into the farm animal space and creating more value for producers and veterinarians,” says Colleen Dekker of Elanco. “Farmers and veterinarians should expect Elanco to continue to focus on bringing innovation designed to meet their biggest challenges supported by a team of technical experts.”

Building the One Health Innovation District in Indiana

Beyond the R&D and manufacturing shifts, Elanco is laying down physical roots in Indiana. In late August, the company announced the purchase of a 56-acre parcel of state-owned land, part of a former GM stamping plant, for $27 million. This plot sits adjacent to previously acquired land already earmarked for its new global headquarters campus. Together, these parcels form the foundation for a planned One Health Innovation District.

This district is envisioned to house research facilities, diagnostic and pilot-scale labs, clinical animal care facilities and collaboration spaces linking industry, academic researchers and other partners. In partnership with Purdue University and the state of Indiana, the development aims to foster a research ecosystem bridging animal, human and environmental health.

For those in food animal health, the district offers closer collaboration between academic science and industry application. That proximity could accelerate development of herd-level solutions for disease management, biosecurity and animal welfare.

What it Means for the Product Pipeline

At Investor Day, Elanco laid out an expectation of five to six major differentiated product approvals between 2026 and 2031. Much of the public focus to date has been on the company’s companion-animal pipeline, including immuno-therapeutics and monoclonal antibodies. Elanco also flagged a potential first-in-class pet immunotherapy, with a projected market launch within the next two to three years, aided by regulatory acceleration under USDA.

While these disclosures emphasize pets, the broader platforms and infrastructure supporting them could also benefit livestock-focused research and development. Biologics, immune-modulating technologies and vaccine platforms developed for companion animals often inform approaches for food animals. The experience gained in those platforms could translate to cattle or swine health solutions.

Implications for Livestock Veterinarians and Producers

Elanco’s shift reflects a transition in how and where food-animal health work gets done. By consolidating R&D and manufacturing in the U.S., the company aims to improve coordination among product development, regulatory preparation and supply chain logistics, factors that affect availability and reliability of herd-health tools.

This transition is worth watching as Elanco’s expanded U.S. infrastructure supports future livestock product development within a more centralized regulatory and manufacturing framework. New product launches and regulatory activity will provide insight into how these investments translate into vaccines, parasiticides and therapeutics relevant to production animal medicine.

What's Driving Canada's Veterinary Drug Shortage and Why it Matters

Tue, 09 Dec 2025 17:52:05 GMT

In Canada, the veterinary community is ringing alarm bells. In late November, the national body representing veterinarians, the Canadian Veterinary Medical Association (CVMA), issued a stark warning : Veterinarians across the country are facing severe shortages of essential drugs, including antibiotics, sedatives, vaccines and other core animal-health products.

Tracy Fisher, president of the CVMA, warns that without reliable access to these medications, veterinarians cannot properly do their jobs, and animals suffer. They are asking both federal and provincial governments to address the issue.

This is not a problem confined to one sector of the profession. According to the CVMA, shortages are affecting companion animal and livestock practices alike, raising concerns not only about animal welfare but also about food safety and stability.

Regulatory Forces Behind the Drug Shortage

Medications that once formed the backbone of routine veterinary care are now increasingly unavailable, disrupting treatment decisions across species and practice types. Antibiotics, anesthetics and sedatives, vaccines and other foundational drugs are among those becoming difficult or impossible to source.

Regulatory changes appear to be a central driver. In 2017, Health Canada imposed new inspection standards requiring manufacturing facilities in other countries to be inspected by Canadian officials. This has increased the burden on companies supplying the Canadian market. For some manufacturers, the cost of these inspections has outweighed the benefit of maintaining approval in a relatively small market.

As a result, Canada has seen a steady erosion of veterinary drug availability. CVMA estimates suggest up to 40% of medications previously accessible to Canadian veterinarians are no longer on the market. While some of these products remain available in the U.S. and elsewhere, Canadian clinics are unable to legally source them, leaving practitioners with fewer and often less-ideal options.

“We’ve lost 40% of the medications that we used to have in the 1980s,” Fisher says. She believes Canada should license products if they have been approved in two other reliable countries with strong safety regulations. “[The drugs] already have the standards met in Europe, Great Britain and the U.S.. Eliminate some of the red tape and bureaucratic processes that are holding up some of these things.”

Why Canada’s Crisis Matters to Global Veterinary Medicine

For veterinary professionals outside Canada, this crisis offers a cautionary example of how quickly a stable system can unravel when regulatory pressure, economics and global supply chains collide.

Veterinary pharmaceuticals rely heavily on multinational manufacturing networks and imported active pharmaceutical ingredients. When compliance costs rise or markets shrink, manufacturers might quietly exit. Once a supplier disappears, alternatives are often limited or nonexistent. Canada’s experience shows how vulnerable veterinary medicine can be when redundancy is low.

Drug shortages also create clinical consequences. When first-line therapies vanish, veterinarians must adapt protocols, rely on substitutions or delay treatment entirely. In livestock systems, these gaps can ripple outward, affecting herd health, productivity and food supply chains. Sustained shortages risk broader impacts beyond the clinic, including public confidence in animal health systems.

What U.S. Veterinarians Should Take From This

The U.S. might not have experienced shortages on Canada’s scale, but the underlying pressures are familiar. Many veterinary drugs already come from a limited number of manufacturers, and global supply-chain disruptions have shown how quickly availability can change.

Canada’s situation is not a prediction of what will happen elsewhere, but it is a reminder of what could happen if market forces and regulatory frameworks drift out of balance. Monitoring availability trends, maintaining contingency plans for essential medications and engaging in discussions around regulatory flexibility could help prevent similar disruptions.

Canada’s veterinary drug shortages are more than an inconvenience. They represent a systemic failure that developed gradually. For the broader veterinary community, the lesson is clear: Access to essential medications cannot be taken for granted. Paying attention now might be the best way to ensure shelves do not go bare elsewhere.

FDA Approves Exzolt Cattle-CA1 for Prevention and Treatment of New World Screwworm

Thu, 04 Dec 2025 18:42:23 GMT

On December 4, 2025, the U.S. Food and Drug Administration (FDA) granted conditional approval to Exzolt Cattle-CA1, a fluralaner topical solution from Merck Animal Health, for the use in beef cattle (≥ 2 months of age) and replacement dairy heifers (< 20 months of age). The approved uses include prevention and treatment of larval infestations by New World screwworm (NWS), and treatment and control of cattle fever tick.

“The FDA is leveraging every resource and authority at its disposal to ensure producers and veterinarians have the critical products they need to protect their livestock and safeguard our food supply against NWS and cattle fever tick,” said Timothy Schell, director of the FDA’s Center for Veterinary Medicine, in a press release . “We remain steadfast in our commitment to ensuring that animal drugs are safe and effective and that food from treated animals is safe to eat.”

While NWS has not yet been detected in the U.S., the threat persists just south of the border with a new case being reported yesterday. Cattle fever ticks, present along the U.S.-Mexico border in south Texas, are competent vectors of Babesia bovis and Babesia bigemina — agents of bovine babesiosis (Texas cattle fever).

“The threat of New World screwworm represents a growing concern to U.S. agriculture, potentially causing devastating economic losses for cattle producers that could reach hundreds of millions of dollars,” said Rick DeLuca, president of Merck Animal Health, in a news release . “We worked closely with the FDA to accelerate availability so that veterinarians and cattle producers will have access to a powerful new tool to protect cattle from these serious parasites, helping to safeguard the industry’s economic future and the nation’s beef supply.”

The conditional approval status reflects FDA’s determination that Exzolt Cattle-CA1 is safe for its labeled use and is reasonably expected to be effective, while requiring that its sponsor, Merck Animal Health, submit further data demonstrating its effectiveness over the next five years to support full approval.

Administration and Use Considerations

Exzolt Cattle-CA1 is a ready-to-use pour-on that delivers the active ingredient, fluralaner, to act systemically against infestations. Administration involves applying a narrow band of the solution from between the shoulder blades to the tailhead. It will be available in the first quarter of 2026 by prescription in 250 mL, 1 L or 5 L bottles.

After administration, there is a 98-day withdrawal period before slaughter to ensure meat from treated animals is free of drug residues. Use is prohibited in lactating dairy cattle, dairy calves, veal calves or bulls over one year of age that are intended for breeding.

This approval of Exzolt Cattle-CA1 complements that of Dectomax-CA1 , which was authorized in September 2025 for prevention and treatment of NWS infestations in cattle. Together, these two products give veterinarians and producers their first pharmacologic defenses against NWS.

Second Screwworm Detection 120 Miles from U.S. Border

Wed, 03 Dec 2025 20:54:05 GMT

There was a new detection of New World screwworm (NWS) in Montemorelos, Nuevo León, Mexico, approximately 120 miles south of the Texas border.

USDA’s Animal and Plant Health Inspection Service (APHIS) confirmed the case in a 22-month-old bovine transported from Veracruz to a feedlot in Nuevo León.

Texas Agriculture Commissioner Sid Miller in a press release emphasized that Texas remains free from detection, but that state officials and agriculture leaders cannot be complacent.

“We will keep working shoulder to shoulder with USDA, Mexican animal health authorities, and our own state agency partners to defend our border and Texans from this dangerous threat. We will protect our livestock, safeguard our economy, and do everything possible to keep the New World screwworm at bay,” Miller says.

He also encourages Texas producers to remain watchful for suspicious wounds, unhealed tissue, or maggot activity in livestock, wildlife, and pets, particularly in locations near the border.

Producers who suspect NWS should immediately contact their local veterinarian and state authorities. Early detection, strict livestock movement controls, screwworm fly suppression and rapid response are the best tools to combat this serious threat.

This detection marks the northernmost active case currently found in Mexico. It is also the second detection at the same Nuevo León feedlot since October. No additional cases were linked to the October detection, and both events appear tied to livestock movements from southern Mexico.

Nightly Battles and Big Losses: Ranchers Demand Reform as Wolves Continue to Wreak Havoc

Wed, 03 Dec 2025 18:42:52 GMT

It’s hard to fathom: 92 confirmed or probable kills of cattle by three wolves during one season (April to October 2025) in the Sierra Valley. For ranchers, it’s more than economical loss — the emotional toll of dealing with wolves targeting their livestock and livelihoods is real.

Reintroduction and management of wolves in Sierra County, Calif., has led to significant challenges. The community, led by officials such as Paul Roen, has been actively pushing for updated management protocols, enhanced deterrence measures and better support from state and federal agencies to address the escalating wolf-livestock conflict.

Roen, a Sierra County supervisor (similar to a county commissioner) and rancher, explains it’s more than a livestock issue; it is a human safety issue.

“These wolves were not bothered by humans whatsoever. I mean, they were not acting like wild animals at all,” he says in reference to the wolves killing cattle earlier this year.

Rick Roberti, California Cattlemen’s Association president and a cattle rancher in Sierra Valley, adds: “For every confirmed kill you find, there’s probably four to six others. The wolves had gotten so used to eating cattle they didn’t hardly even look at a deer if they could find one.”

Roen and Roberti both stress the wolves have no fear of humans, with frequent sightings near homes and barns.

The severity of the attacks led Roen and other local officials to declare a state of emergency, drawing statewide and media attention. Despite the efforts of ranchers and local authorities — including constant night patrols, protective measures and deployment of technology like drones — wolf predation persisted. The community also engaged with state and federal resources, including a Strike Force sent by California Department of Fish and Wildlife (CDFW) to document the losses and explore possible intervention .

The program, designed to prevent livestock attacks on ranching properties in the heavily impacted Sierra Valley, deployed more than 18,000 staff hours across 114 days, engaging in 95 hazing events that helped to prevent an even greater loss in cattle deaths.

Eighteen Sierra Valley ranches enrolled in the program. CDFW staff also assisted ranches in evaluating the use of wolf-deterring fladry and ensuring livestock carcasses are correctly disposed to avoid attracting scavenging wolves. Additionally, the program helped facilitate depredation investigations, enabling ranchers to access compensation through CDFW’s Wolf-Livestock Compensation Program .

Following the unprecedented level of livestock attacks across the Sierra Valley, CDFW, in coordination with the U.S. Fish and Wildlife Service (USFWS), took the step of lethally removing four gray wolves from the Beyem Seyo pack.

“This action follows months of intensive non-lethal management efforts to reduce livestock loss and is grounded in the best available science and understanding of wolf biology,” according to the press release.

Roen says progress dealing with the wolf issue came with federal involvement and local law enforcement support. He says when the sheriff got involved , people woke up in Sacramento.

Read more about how sheriff departments from seven California counties united to oppose environmental polices they believe threaten ranchers and farmers.

Not Just California

The gray wolf is on the federal endangered species list except in the Northern Rocky Mountain region of Idaho, Montana and Wyoming, the eastern one-third of Oregon, Washington and north-central Utah. In Minnesota, the gray wolf is considered threatened. Because of these protections, killing a wolf in the states where it’s protected is illegal, even if it’s seen killing livestock.

Luke Morgan, Lightning Bolt Cattle Company general manager, has been dealing with wolves since 2011 when they first came to Oregon. Morgan manages 2,500 mother cows on multiple locations in Oregon and Washington using both public and private lands.

A pack of wolves that live on one of the Lightning Bolt ranches in western Oregon have been causing havoc the past couple years. According to Morgan, the wolves killed more than 25 head of livestock from mid-October to mid-November.

He says the wolves prey the weak-minded: “Whatever can’t take the pressure … the ones that will break and run.”

(CDFW)

Cattle producer Amy Anderson Fitzpatrick says her family has also been dealing with wolves since 2011. They raise cattle in southern Oregon during the grazing season (May to December), then move the herd to winter in Northern California. The base ranch, called Rancheria Ranch, is in the mountains of Oregon and is a mix of owned land and permitted grazing. The operation includes commercial cow herd plus some yearlings.

Since 2019, Fitzpatrick says at least 24 cattle deaths have been attributed to wolves, though actual losses are likely higher due to unconfirmed cases in the rugged terrain.

“I have learned far more about wolves and their behavior than I could ever imagine. Wolves kill for food, yes, but they also kill to hone their skills, teach their young and for fun. We have witnessed wolves literally bumping livestock bedded down to get them up and running to chase them,” Fitzpatrick says. “We’ve been dealing with it for about 14 years. … The earlier pack, the Rogue Pack, would hit Fort Klamath hard in the summer months when there was an abundance of yearling cattle, then in the fall they’d come over the hill to Rancheria and hit us. Now we deal with what is known as this Grouse Ridge Pack, which seems to just like to hang out at the ranch and hit our permit country in the summertime.”

Fitzpatrick says they previously anticipated up to five losses per year from cattle turned out on the range as a cost of doing business. With the increase in wolf population, the ranch tallied between 35 and 40 mostly weaned calves during the 2024 season.

The Rogue Pack would kill livestock as sport and not consume the animals. However, the current, larger pack tends to consume more carcasses, further complicating verification.

In Wisconsin over the past 12 months, wolf attacks on livestock have increased. According to the state’s Department of Natural Resources (DNR), there have been 62 livestock depredation incidents in 2025 — 45 killed and 17 confirmed harassments — all of which are either livestock or pets. That’s nearly double the number of incidents reported just three years ago.

According to the Wisconsin Farm Bureau : “Wisconsin’s wolf population has rebounded from extinction to an undeniable conservation success. But lately, it feels more like a horror story than a success story.”

Wolves Are Not Going Away: Ranchers Push for Practical Management Tools

(Paul Roen)

Financial Loss is Real

Herd-level effects beyond death loss include lower conception rates, 50 lb. to 75 lb. weaning weight declines and cow herd fear. Wolves have changed cattle behavior significantly.

Fitzpatrick says the presence of wolves has caused observable stress and aggression in the cattle, leading to behavioral changes, abortions and decreased weaning weights.

“Wolves actively harass resting cattle, preventing them from relaxing or thriving,” she says.

Morgan says herd experience more vulnerability during calving season. He points out calves and protective dams are high-risk with wolf attacks leading to increasing accidental calf deaths and stress-related herd disruptions.

Research by Tina Saitone, a University of California-Davis professor and cooperative Extension specialist in livestock and rangeland economics, found one wolf can cause up to $162,000 in annual financial loss .

Compensation is Available But Falls Short

Compensation frameworks exist but often lack speed and scope and require confirmations that are often unfeasible. Morgan says there’s not even close to enough funds in the pool to cover all the losses.

“There is money appropriated in California, but we’re just having a hard time getting it,” Roberti adds. “Most have been waiting since April.”

All four producers say depredations are significantly undercounted compared with real losses due to terrain, investigation lags and evidence requirements. A shared frustration is the fact if an animal is nearly completely consumed, the investigators can’t find the evidence it was a wolf attack and thus, it does not count as a wolf depredation.

Emotional Toll is Substantial

For cattle producers impacted by wolves, it’s more than the financial toll; it’s the human factor, the stress incurred.

“Financial-wise, it’s huge. It’s astronomical, if you really dig into it, but the mental capacity it takes from us and the people who work for us is huge,” Morgan says. “The emotional toll we have to go through just watching and observing cattle, and we spend every day we possibly can trying to keep these animals alive.

“There’s nothing pretty about the way [wolves] kill animals,” he continues. “For us to go out and find them or have to deal with that, it’s huge emotionally.”

Fitzpatrick explains the losses due to wolves have deeply affected her dad.

“My dad is 81 years old, and I have never seen him so depressed,” she explains. “He’s not the same; he’s lost the fight. It’s like we’ve lost. How do you put a price tag on that?”

Dealing with wolves it is a safety issue as well, Roberti adds. As producers stay up all night checking on and protecting their cattle. Fitzpatrick agrees, summarizing the stressful steps she takes to check cattle, noting she now avoids certain tasks due to the increased risks to herself and her dogs.

Documenting the events in Sierra County, Roen says he hopes their experiences can be used as a road map for others. He plans to share plans, forms and training materials with ranchers facing similar threats.

“We created different plans and trainings we will allow everybody to plagiarize,” he says.

The Cost of Coexistence With Wolves

New Research Exposes Stagnant Biosecurity Efforts in the U.S. Dairy Industry

Tue, 02 Dec 2025 19:20:34 GMT

When it comes to biosecurity, U.S. dairy farmers are more reactive than proactive and some neglect the basics, making operations vulnerable to evolving disease threats, according to new research released Tuesday at MILK Business Conference .

The study found farm hygiene and herd health aren’t top of mind on all farms and one-third of farms don’t proactively review their biosecurity plans indicating a potential lack of ongoing commitment or adaptation.

There is a silver lining: More than 70% of large dairies say they are already working on improvements, meaning some in the industry are prioritizing biosecurity.

The recent research conducted by Farm Journal, which surveyed more than 300 dairy producers, looks at trends and potential vulnerabilities that might be affecting dairy farms nationwide. As disease challenges such as highly pathogenic avian influenza (H5N1), New World screwworm (NWS) and bovine spongiform encephalopathy (BSE) continue to mount, biosecurity remains a critical concern for the industry.

“We need biosecurity efforts to be more impactful at the ground level. Not only to prevent major outbreaks, but to even protect employees and families from the things being taken home every day,” says Kirk Ramsey, Neogen’s professional services veterinarian who reviewed the biosecurity survey results.

Biosecurity Plans Lag Behind Threats

The survey reveals even among farms with established biosecurity strategies, commitment to reviewing and adapting these plans is lacking. While 68% of farmers with at least 250 dairy cows report having a biosecurity plan, 34% admit they do not review their plans regularly.

(Farm Journal)

On a positive note, 72% of dairy operators with 250-plus cows report they are currently making improvements to their biosecurity versus 58% of smaller dairy operators. Those producers are making improvements for a host of reasons, including recent on-farm or neighboring farm disease outbreaks, veterinarian recommendation and government or regulatory authority guidelines.

One respondent shares because their farm is a “closed herd” they’re not making any improvements to their biosecurity plan. All of this hints at a broader problem: Ongoing biosecurity practices might not be keeping pace with evolving threats.

Back to the Basics With Farm Security

The survey also uncovers significant gaps in fundamental farm security. More than 20% of surveyed dairies neglect to secure access to barns and animal housing. Monitoring or restricting visitor access is also a blind spot for 16% of producers, and only 33% of producers use camera surveillance to oversee their facilities. Additionally, 38% fail to control or limit access to areas where feed is stored or provided.

(Farm Journal)

Gaps in Hygiene and Herd Health

When it comes to farm hygiene and animal health practices, 72% of larger dairy operations have hand-washing stations included in their biosecurity protocol, and 75% use separate equipment for handling feed and manure. Even though more than half of respondents use technology, such as herd activity monitoring systems, to help identify sick animals, the overall picture suggests room for improvement in daily hygiene and health protocols.

(Farm Journal)

Training and Education Should Be Proactive

The approach to biosecurity training also calls for reform. The findings show a reactive pattern, with 32% of farms providing training only in response to biosecurity issues, while another 30% conduct quarterly meetings. These figures reveal substantial portions of the industry lack consistent, proactive staff education, an essential pillar of effective biosecurity management.

Chief Science Officer Jamie Jonker, Ph.D., with National Milk Producers Federation says biosecurity on dairy farms is a continuous process that requires proactive updates and employee education to keep pace with evolving disease threats.

“The National Dairy FARM Program offers comprehensive biosecurity materials and evaluation tools as well as certified FARM Biosecurity evaluators who can draft tailored plans and guide training to ensure consistent implementation,” he says. “Leveraging these resources helps producers stay ahead of risks and maintain a strong, resilient operation.”

(Farm Journal)

Cybersecurity: An Emerging Concern

Beyond biosecurity, the increasing reliance on technology introduces cybersecurity challenges. Only 29% of farmers have collaborated with cybersecurity experts to protect their farm systems and data. As farms grow more technologically interconnected, safeguarding digital infrastructure is an emerging need.

The insights from Farm Journal’s recent research paint a clear picture for the U.S. dairy industry: In an era of escalating disease threats such as H5N1 and NWS, a reactive or static approach to protection is no longer sufficient. Ultimately, this research serves as a pivotal reminder that biosecurity and cybersecurity are not one-time tasks, but dynamic, ongoing processes demanding continuous review and proactive management.

“Improvements in biosecurity will require a paradigm shift in how we see our individual operations’ vulnerabilities,” Ramsey says. “I believe there are some misconceptions around what biosecurity looks like. For many, it’s thought of as Tyvek suits and face masks, not clean boots and coveralls, and shower-in-shower-out facilities, not limited-farm entry. There are simple ways to create biosecurity plans into every operation, and there are experts in our industry building innovative solutions to the complexities of the cattle industry.”

How Data, Genomics and Collaboration Are Transforming Cattle Genetics and Herd Profitability

Tue, 18 Nov 2025 14:50:11 GMT

Avoiding the pitfalls of the past, Marty Ropp and his team at Allied Genetic Resources (AGR) integrate science, service and transparency to advance genetic potential across the beef supply chain.

Ropp was the featured guest in “ The Future of Beef Show ” podcast, episode 14 .

Ropp and the podcast hosts explore the evolution and future directions of genetic improvement in the beef industry. He shares his unique journey from swine to beef genetics, emphasizing the critical role that data, technology and customer collaboration play in driving progress and profitability for ranchers and the broader supply chain.

Raised in the pig genetics industry, his formative years included education at Bethel College, Kansas State University and the University of Missouri, where he earned a master’s in pig genetics. In 1998, a pivotal year for the pork industry when market collapse forced many out of business, Ropp transitioned into beef genetics, thanks in large part to Jerry Lipsey, former American Simmental Association (ASA) CEO. Ropp says his 12 years at ASA set the stage for his founding AGR in 2010.

Lessons Learned

The 1998 crisis in pork is a foundational lesson for Ropp. He describes how the industry’s failure to adopt technology, gather and apply data, and engage with customers led to widespread business failures. Many pig genetics providers focused on tradition and appearance, neglecting scientific data and market signals — ultimately opening the door for larger, technology-driven players who could deliver what the market needed.

He says this experience shaped his determination to avoid repeating those mistakes.

“This is not sustainable, and it won’t last, and then it didn’t,” Ropp explains. “And so, I’ve been trying to apply that thought process to what I do in the beef industry ever since.”

What is AGR?

AGR is a member-owned company designed to be a full-service genetic provider for the beef industry, offering services and products that help ranchers and cattle producers improve genetics, collect and apply data, and ultimately increase the profitability and value of their herds. The company combines seedstock, feeder calf marketing, genomics and data services under one umbrella, with an emphasis on actionable genetics, customer support and continuous innovation.

He explains he started AGR because he saw critical gaps in the genetics industry.

“The idea that genetics providers needed to do more than just what they were doing, which was making what they wanted to make, and marketing them as the best genetics in the world — they needed to build closer relationships with their customers, and ultimately become part of the food business, part of the supply chain,” Ropp says.

AGR’s core mission is to increase the total value across the beef industry through better genetics, rather than simply re-distributing existing value among producers and stakeholders.

“Our program is designed to add to that pie, take cost out and add income,” Ropp summarizes. “Anything like being more involved with systems farther down chain, try to get more value from the genetics that we’ve produced and our customers make — anything like that has to be in our future plan.”

Here are some key takeaways from the discussion:

1. Data and technology drive progress. The future of cattle breeding relies on rigorous genetic evaluations, genomic testing and using data to improve both profitability and sustainability for ranchers and producers.

“We 100% believe in the genetic and genetic evaluation of data and genomic evaluation — 100% use that data to prove sires move forward as fast as they can on the back end. Then the feedback has to come,” Ropp says. “That data-driven genetic improvement for the future is what we need, and that’s how we stay engaged.”

2. Customer relationships and service. AGR emphasizes close, long-term relationships with customers, helping them through customized genetic evaluation, actionable recommendations and support services extending beyond seedstock sales.

3. Value creation through data. Collecting and utilizing high-quality commercial and seedstock data is critical. However, data’s value depends on creating actionable insights that directly improve breeding decisions and market outcomes, rather than simply accumulating or selling raw data.

“The data is necessary and valuable,” Ropp says. “But again, if you can’t feed that into a system that pays for improvement down chain, then that data is only valuable from a cost reduction ... and not really from an industry participation standpoint.”

4. Genomics for all sectors. While genomics is standard among seedstock producers, new efforts like the Right Bull program are bringing actionable, simplified genomics solutions to commercial producers, even in group-managed operations.

“Investment in genomics by itself does not drive any profitability; those genomics have to be used in tools and actionable tools that you can take advantage of immediately,” he says.

5. Feedback loops and incentives. Effective genetic improvement requires a feedback loop where improvements lead to measurable value for the commercial producer: higher calf prices better conception rates, incentivizing continued participation.

6. Industry collaboration and partnerships. AGR and its divisions actively work with both members and non-owners, as well as with technology companies, breed associations and other stakeholders to advance genetic progress across the beef industry.

Ropp sees a need for more comprehensive commercial data, better feedback loops and systems that translate genetic progress into tangible rewards for producers. He advocates continuous innovation — using new technologies, transparent service models and collaborative partnerships to ensure that genetic improvements benefit the entire industry, not just a select few.

Check out the podcast to learn more about Ropp’s strategy of fusing technology, data and expert service to deliver actionable solutions helping ranchers achieve sustainable profitability and industry resilience.

Next Step in the Screwworm Fight: USDA Announces Opening of Sterile Fly Dispersal Facility in Tampico, Mexico

Thu, 13 Nov 2025 18:38:40 GMT

USDA announced Thursday the opening of a sterile fly dispersal facility in Tampico, Mexico. The Tampico facility will allow USDA to disperse sterile flies aerially across northeastern Mexico, including in Nuevo Leon. This announcement is the next milestone in the fight against New World screwworm (NWS).

“The opening of the Tampico sterile fly dispersal facility is another incredibly important tool in our arsenal to stop the spread of screwworm. The facility will ensure flexibility and responsiveness in northern Mexico, giving us a greater ability to drop sterile flies and continue to push the pest south,” said U.S. Secretary of Agriculture Brooke Rollins in a press release . “Stopping the spread of screwworm is a top priority for the entire Trump administration.”

Last week Rollins met with Mexican President Claudia Sheinbaum and her counterpart Secretary Julio Berdegue on the joint response to NWS.

“We are boosting our efforts and completing a joint review of our screwworm operations in Mexico to ensure our protocols are being followed,” she says. “As we enter the winter months , we continue to prioritize the response in Mexico and the rest of our five-pronged plan to protect U.S. livestock and the livelihoods of American farmers and ranchers.”

A proven method for NWS eradication is releasing sterile male flies to mate with wild females collapsing the population over time. There are two methods of dispersing sterile insects – aerial dispersal and ground release chambers. Aerial operations are preferred because they allow for dispersal at a steady rate through a large area and also because sterile insects may be dispersed in areas that are unreachable from the ground. Ground release chambers are used when there’s a need to quickly deploy sterile insects outside of the dispersal facility range.

The Smell You’ll Never Forget: A Calf Infested with New World Screwworm

According to the press release, USDA continues to disperse 100 million sterile flies per week in Mexico, but until now, aerial operations have been limited to southern Mexico, necessitating the use of ground release chambers in more northern areas of the country. Mass production and targeted dispersal of sterile flies remain critical components of our effective response.

Although Mexico continues to confirm new cases of NWS, the overwhelming majority of these remain in the far southern part of the country, with no significant northward expansion over the past several months. Should that change, the Tampico facility will allow USDA to immediately tackle any cases that occur elsewhere in Mexico.

The two northernmost detections (approximately 70 and 170 miles from the U.S. border, respectively) occurred in Nuevo León, on Sept. 20 and Oct. 5 , in young cattle transported from Chiapas, Mexico.

Neither case is still active and there have been no additional detections of NWS flies in traps or cases in animals in Nuevo Leon. USDA continues to disperse sterile insects in Nuevo Leon, and will now transition from ground release chambers to aerial dispersal in those areas.

USDA produces sterile flies for dispersal at the COPEG facility in Panama. USDA is also investing $21 million to support Mexico’s renovation of an existing fruit fly facility in Metapa — which will double NWS production capacity once complete. With ongoing support from APHIS technical experts, Mexico anticipates this sterile fly production to begin as soon as summer 2026.

To expand our domestic response capacity, USDA has also begun construction on a sterile fly dispersal facility at Moore Air Base in Edinburg, Texas, that is projected to begin operating in early 2026. APHIS is also expediting design and construction of a sterile fly production facility in southern Texas, with a targeted maximum capacity of 300 million sterile flies per week.

USDA continues to work with Mexico’s agriculture authority, SENASICA, to implement the collaborative NWS Action Plan and guide trapping, surveillance and movement protocols to help stop the northward spread of NWS.

Trade Mission While In Mexico

While Rollins was in Mexico last week, she also led the largest U.S. Department of Agriculture agribusiness trade mission in history. During the mission, 41 U.S. businesses, 33 cooperators and agriculture advocacy groups, six state departments of agriculture, and 150 participants conducted more than 500 business-to-business meetings during the three days.

According to a USDA press release , “This was a critical opportunity for American business to further trade ties and for USDA to continue its aggressive response to NWS in Mexico and continue to hold Mexico accountable for its commitments to the 1944 Water Treaty.”

Monitoring Tools Can Strengthen Herd Health Programs

Early identification of health challenges is one of the most effective ways to reduce disease severity, minimize treatment costs and support long term herd productivity. While experienced caretakers have always relied on stockmanship and close observation, today’s operations can benefit from data beyond what we can consistently monitor with our own eyes. Monitoring tools provide an additional layer of insight, helping recognize subtle changes in behavior, intake or environment before clinical signs are obvious.

Dr. Tiago Tomazi, dairy technical services veterinarian with Merck Animal Health, shared his advice at the Dairy Cattle Reproductive Council annual meeting on how the dairy landscape has progressed, allowing us to use monitoring technologies and management practices for improved animal health.

“If we go back to the ‘80s, we can say that dairy farming was still dominated by small-and-medium-sized family farms, right? We used to call cows by name,” Tomazi says. “Then the ‘90s and 2000s came, and there was a marked acceleration in the growth of large scale operations. There was an explosion of studies, of investigations, and scientific investigation that helped a lot to bring us to the point we’re at nowadays as far as reproduction and production in dairy cows and cattle health.”

Following this growth in knowledge came the development of monitoring technologies to assist producers and veterinarians identify potential animal issues earlier.

That being said, data-driven decision making does not necessarily require advanced technology. In many herds, structured record keeping, routine scoring (such as body condition scoring, lameness scoring or feed bunk assessments), and consistent visual checks are foundational monitoring practices. The goal is to identify patterns and changes over time, not just isolated events.

Combine Technology with Strong Management Practices

When technology is added on top of strong stockmanship, the combination can be especially powerful.

“Point No. 1 is that monitoring systems are not a diagnostic tool,” Tomazi reminds. “But they help in identifying a cow that’s not having a good day.”

These activity monitoring technologies are not meant to tell you what ailment the cow has, but rather to alert you that a cow may be worth checking up on.

“Biology is not math,” Tomazi says. “While math uses formulas, numbers and calculations to get you the exact result, biology [has to] take into consideration a set of factors associated with the biology of the cow and the environment.”

While a variety of wearable tools exist for the earlier recognition of health changes, the interpretation of the data remains critical. Similar patterns can have multiple causes. For example, a decrease in rumination may reflect heat stress, early illness, social stress or rumen upset. Likewise, changes in activity could indicate estrus, discomfort or pain. Connecting these data points to clinical reasoning and management is key.

Application Evidence from Research

Data from these monitoring tools can be applied for health predictions in a number of scenarios.

Chabel and colleagues from the University of Florida evaluated of over 4,500 dairy cattle across three commercial dairy herds wearing automated monitoring devices designed for estrous detection. They found early postpartum estrous characteristics were valuable indicators of reproductive potential; they were able to identify cows at risk for suboptimal fertility. By combining these characteristics with other health, genetic and environmental data, they were able to improve the prediction of fertility outcomes and provide targeted reproductive management for the cattle.

A series of three studies by Stangaferro and colleagues at Cornell University investigated the use of automated monitoring devices for the identification of health issues in dairy cattle. They found health index scores (calculated using an algorithm using rumination and activity data) provided sensitive detection for cattle with metabolic and digestive disorders , reducing time to clinical diagnosis by approximately 2 days. However, this system was less sensitive for the detection of mastitis and metritis , being most effective for cattle with severe cases.

While these monitoring devices may not perfectly identify all health issues in your herd, they can certainly help identify some disease signs earlier than human observation alone. It’s also important to note that the implementation of these monitoring devices will be different from farm to farm.

“We have to take into consideration the level of disease protection you want at your farm as well as the feasibility and labor capabilities,” Tomazi says. “You can be very intensive, but if you don’t have the people to provide you with that intensity, then it makes everything harder. On the other hand, you can be less intensive and find that balance where you’re not going to compromise the reproduction or production during the location of those cows.”

Data Interpretation is just as Important

Training caretakers to recognize when and how to respond to monitoring data is just as important as selecting the technology. A monitoring system is only as good as the team interpreting it.

While the benefits can be significant, monitoring tools also introduce challenges. The amount of data generated can be overwhelming. Time and training is required to get the most out of your investment and use the data effectively. This provides a great opportunity for veterinarians and producers to work together in prioritizing the metrics that are the most actionable and will make the most impact on the operation’s herd health goals.

The Future with Monitoring Tools

Looking ahead, predictive models and machine learning based alerts are likely to play an increasing role in herd health programs. With these systems will come the need for increased expertise on interpretation, contextual decision making and ongoing evaluation of how monitoring tools fit into preventative care strategies.

“I think integration is what we are walking toward,” Tomazi says. “The integration of these technologies with biological factors and management factors all together will help us make decisions considering the specific scenario at each dairy farm.”

Ultimately, monitoring tools are most effective when combined with strong stockmanship and veterinary oversight. When data and observation inform each other, disease can be detected earlier, interventions become more targeted and herds can become healthier overall.

A Conversation With Ag Secretary Rollins on Labor, Disease and MAHA

Thu, 13 Nov 2025 13:33:15 GMT

U.S. Secretary of Agriculture Brooke Rollins stuck to streamlining the federal government labor rules to alleviate dairy’s worker crisis and said more aggressive measures are coming to prevent and contain disease, in an interview with Dairy Herd Management. Rollins this week was at the joint annual meeting hosted by National Milk Producers Federation, the United Dairy Board and the United Dairy Industry Association in Arlington, Texas.

While there, she said the H-2A visa program is particularly broken for dairy, which requires year-round support instead of seasonal workers. She also said measures, such as mandatory testing for lactating dairy cattle prior to interstate movement, are not aggressive enough to address modern biosecurity threats.

Below is a summary of Dairy Herd’s 20-minute conversation with Rollins, who discussed labor, disease prevention as well as her feelings on the “Make America Healthy Again” movement.

What Federal Efforts Are in the Works to Ensure Adequate Labor for U.S. Dairies?

One of the central concerns among dairy producers, and the entire industry, is comprehensive immigration reform. To put it in perspective, more than two-thirds of today’s 9.36 million dairy cows are milked by immigrant laborers in the U.S., according to the National Milk Producers Federation.

Currently, the H-2A visa applies strictly to seasonal or temporary labor. Dairy operations, however, require consistent, skilled workers every day of the year. Milking and caring for cows, managing processing facilities and ensuring food safety are daily tasks that don’t pause between seasons. This mismatch leaves dairy farmers and processors nationwide without a legal means to fulfill their guestworker needs.

In addition to the need for year-round help, Secretary Rollins notes farmers must interact with three different federal agencies to use the H-2A program. Moreover, the costs associated with securing labor have significantly increased, with reports from farmers in south Texas indicating average hourly costs, including transportation and housing, reaching $30 to $35 per hour. Comparatively, similar labor across the border is $2 per hour, Rollins says, illustrating a system that is both unsustainable and inherently unfair.

Ideally, any H-2A program changes will reduce costs and red tape, but comprehensive solutions ultimately require congressional action.

In addition to visa programs, Secretary Rollins says the current administration remains focused on sealing borders and mass deportations.

“Everyone understands the dynamics of an open border, and the millions and millions, we’re unable to count how many, that crossed during the last administration. The President’s No. 1 promise as a candidate in 2022 through 2024 was sealing the border and mass deportations,” she says. “Looking at this challenge through the lens of understanding labor is absolute when we can’t feed ourselves, combined with where we are in terms of immigration, those are the nuances.”

How is the Administration Addressing Threats to Animal Ag?
On day 1, after being sworn in as Secretary of Ag, Rollins was briefed on HPAI . She made it clear that while some measures, such as mandatory testing for lactating dairy cattle prior to interstate movement , had been enacted, a broader and more aggressive approach is necessary. Recognizing that maintaining the status quo was insufficient, a comprehensive strategy was essential — not just from USDA but across the entire federal government.

“I realize there are lots of opinions on my boss, President Trump, but I think the one thing that most people would agree on is that he leaves it all in the field. And, that we have to do everything we can for this moment that we were given to fix a very broken system, whatever that system may look like, in this case, which is animal disease,” Rollins says.

In February 2025, the Trump administration set forth a five-point plan to combat HPAI . Rollins notes the dairy sector, in particular, showcased remarkable adaptability to HPAI threats, demonstrating industry resilience and proactive measures.

Significant investments, such as a $100 million innovation grant , have been allocated to explore vaccines and therapeutic solutions. However, the complexities of viral mutations necessitate caution, especially regarding vaccination strategies, to prevent potentially more dangerous strains from emerging.

“I think we’re going to make more progress than perhaps has been made. Having said that, it’s a virus and the virus always wins,” she says, noting they are worried about New World screwworm and took aggressive actions to combat that by closing several ports.

“We’ve not imported new animals, which is one of the reasons beef prices are up, but we are looking now to figure out how to start reopening ports. I think we’ve gotten our arms around exactly what the problem is,” she says. “We’re building out new sterile fly facilities, which is the only way we eradicated it 30 to 40 years ago, but we have a really good system in place.”

Rollins shares collaborations with international counterparts are stronger, creating an unprecedented partnership with Mexican authorities to manage and preempt future animal agriculture outbreaks effectively. Enhanced border protocols, including disinfection and ivermectin treatments for imports, underscore a commitment to protecting livestock health.

“I feel confident that we are aggressively attacking all pieces of NWS,” she says.

What Does the MAHA Movement’s Mean for Dairy?
The “Make America Healthy Again” movement aims to revamp the nation’s food system, and Rollins offers reassurance dairy products at the forefront.

“Health care costs too much. We’re not getting the care we need, especially to vulnerable populations. How do we fix that?” she asks. “Over the last year, it is completely flipped to, what are Americans eating? What are we serving in our schools? What are we serving in our SNAP program, which 42 million Americans are on the food stamp program.”

While the current economic situation is troubling, Rollins is confident in the long-term potential for profitability and sustainability in the dairy industry.

“What milk, cheese and other dairy products mean as we completely and fundamentally shift our entire food system is our dairy industry is at the very front tip of the spear,” she says, noting the response markets are answering and the dairy industry, too, with the $11 billion in new processing plants, U.S. dairy is riding a wave of momentum that is fueled by consumer demand.

“In the long term, I’m not sure there is an agriculture industry that has more to gain and that will see more of a pivot toward real profitability and real sustainability than this [dairy] industry. I could not be more excited to help lead on that,” she says.

Juggling Glass Balls: How Veterinarian Micah Jansen Prioritizes What Matters Most

Fri, 07 Nov 2025 14:55:49 GMT

“The key to juggling is to know that some of the balls you have in the air are made of plastic and some are made of glass. And if you drop a plastic ball, it bounces, no harm done. If you drop a glass ball, it shatters, so you have to know which balls are glass and which are plastic and prioritize catching the glass ones.”

When Micah Jansen, DVM, first heard the glass ball theory by author Nora Roberts, she remembers instantly connecting with it.

“As working moms, we have a lot of things we are balancing,” Jansen said on The PORK Podcast . “This concept helps me remember that I must differentiate the glass balls from the rubber balls. If I drop a rubber ball, like failing to get a deliverable to a co-worker on Friday, I can get it to them on Monday. But my daughter’s Christmas program – that’s a glass ball I cannot drop because it won’t happen again.”

She says understanding the difference between the two has helped her focus and be more deliberate as a working mom. It’s also helped her learn how to prioritize and say no at times.

“When I start getting upset about not getting something done or not being somewhere I wanted to be, I have had to learn to say, ‘Okay, even though I’m upset, this is a rubber ball. It is not the end of the world if I can’t accomplish this because I’m catching this glass ball over here.’”

As a swine tech services veterinarian with Zoetis, the struggle is real at times. No two days are alike for Jansen who has been with the company since 2015. From helping people understand how different products work and troubleshooting with clients on swine health issues to assisting with research projects and hosting student interns, Jansen has learned that her role requires some juggling.

Fortunately, she enjoys the challenge.

The Face of Veterinary Medicine is Changing

“The swine industry is constantly changing,” she says. “It’s becoming more integrated, and with those changes in structure, has also come a change in what swine medicine looks like.”

More production systems today have staff veterinarians who work full time and focus on their system’s pigs. Veterinary clinics are becoming more consolidated, too. There has also been a major shift from mostly men to mostly women entering practice.

She believes this may be another reason why the structure of swine medicine has changed, too. Women are multi-taskers at heart and as more women step into veterinarian roles, Jansen says they have sought out how to find balance between their roles at work and at home as mothers so they could do both well.

“I’m still the only woman in the room sometimes,” Jansen says. “But, I’ve never wanted that to define me. I try to focus on what I know without a doubt to be true and also be humble. If I don’t know the answer to something, it doesn’t mean I can’t find it. I’ve always been somebody who would rather not know the answer and come back to someone than to tell them something that’s wrong.”

Jansen spends a lot of time working with students through internships and other research programs. She says they’ve taught her a lot along the way. She is impressed how younger generations are realizing sooner in life that you only have so much time to devote to certain things like work or school, while also taking care of your mental health and well-being.

“They are better at saying, ‘OK, you want me to complete this task, but I know I have exams next week so I can’t commit to getting it done today. However, I will get to it as soon as I’ve completed my other exams,’” Jansen says. “Never in a million years would I have ever done that! But I admire them for being honest with themselves.”

Hard Decisions

A big part of being a great swine veterinarian is making hard decisions and offering clients holistic support.

Terry Moeller, a Zoetis strategic account manager and colleague, says, “Micah always strives to do the right thing when it comes to pig health, and she has extensive knowledge of critical financials that yield a strong return on investment for our customers.”

Her grasp of the swine industry and understanding of the decisions producers face every day have helped her be successful in her role.

“The decisions that we help our clients make are going to impact essentially whether or not they can feed their families,” Jansen says. “Regardless of if you’re in private practice or if you are a staff veterinarian working for a production system, you constantly must keep in mind the other piece of it that adds up fast. When we make a decision to treat an animal, it’s not just a single animal. You have to take it times 1,000, times 10,000, or times 5 million, depending on what decision you’re making.”

Abbey Briscoe, a veterinarian with Harding Veterinary Services, says this is one of the things she admires about Jansen.

“Micah doesn’t settle for ‘easy.’ She doesn’t have her mind made up with an answer to a problem for a client and genuinely takes her time to listen to everything surrounding an issue, gathering all sides and information before thoughtfully answering,” Briscoe says. “She will follow up with additional advice and options once she has had more time to digest and gather outside expert feedback on a case. She honestly wants her clients to have the best possible insight to an issue.”

One of the not-so-easy roles Jansen plays at Zoetis is serving as a go-to-person on influenza. She admits she actually enjoys studying influenza.

“I think people don’t like flu because it can be really overwhelming,” she points out. “Part of the reason it becomes so complicated is that the influenza virus is so good at changing. We continue to see changes in the virus over time, and what makes it even more nerve-wracking is that interface between pigs and people.”

Biosecurity is key to fighting influenza. She says it’s a constant challenge of knowing what you should do next when it comes to animal husbandry, pig movement or vaccination.

“And then what do we do about caregivers? Even if they’re sick, they want to come into work because they want to be able to feed their families. But at the same time, how do we decide when a sick employee could be putting that population of pigs at risk?” she says. “There are so many moving pieces.”

If she could share one message with the industry now, it’s a simple, but profound one.

“Let’s make sure we’re doing things the right way,” Jansen says. “We know the right way. We love data in the swine industry, and we always talk about how it drives our decisions. Let’s make sure that’s not just something we’re saying. Let’s make protocol decisions based on that concept and doing everything we can to get better.”

Jansen shares more about swine health, her days at the University of Illinois and her passion for team roping and more on The PORK Podcast. You can watch it here on YouTube or listen anywhere podcasts are found.

Marketing Cull Dairy Cattle: How to Integrate Welfare and Economics into Decision-Making

Wed, 29 Oct 2025 19:54:46 GMT

Dairy cattle span multiple product sectors, with a first career as a dairy animal and a second career as a beef animal. With a declining cattle herd population in the U.S., focusing on health and welfare of each animal remains important. In addition, finding extra value in each animal is critical to each operation’s business.

Look At The Factors
According to the 2022 National Beef Quality Audit, dairy or beef cows and bulls that can no longer be used for their original purpose are still valuable. Cull cattle, or animals being removed from the herd, can be marketed in several ways dependent on the type of operation, their production and marketing goals, resources, and other factors.

In a guide titled “Right Way. Right Time. A guide to cull dairy cattle management,” the National Dairy Farmers Assuring Responsible Management (FARM) program collaborated with CattleFax and the National Cattlemen’s Beef Association to evaluate these various factors and improve cull cattle management to enhance animal welfare while considering economics.

This document uses established standards to address key areas of opportunity for effective cull cattle management and provide strategies for making timely culling decisions and improving welfare. It is designed to help producers examine the opportunity to capture more value.

“‘The Right Way. Right Time.’ handbook provides practical steps to help farmers and veterinarians make the right decision on the complex question of ‘When is the right time for a dairy cow to change careers,’” says Meggan Hain, chief veterinary officer for the National Milk Producers Federation and the National Dairy FARM Program.

Topics Covered
The handbook establishes a mechanism for proper diagnosis, treatment protocols and training topics like fitness for transport and euthanasia decisions.

When it comes to minimizing stress during transportation or career changes, understanding how temperature, wind speed, humidity and storms affect cattle and calves during transportation is important. There are also many aspects of transportation that can be controlled — including where the animal is marketed, the equipment used, stocking density and transporter education. Recommendations for calf transport from the American Association of Bovine Practitioners (AABP) are included in the resource.

The BQA Transportation certification, which helped guide the ‘Right Way. Right Time.’ documents, provides direction on fitness for transport decisions with topics such as mobility scoring, body condition scoring, length of transport and withdrawal times. Both educational resources can be training tools for veterinarians when working with their dairy and calf operations.

For example, the following are points to consider before deciding to ship an animal:

Ensure all animals have cleared withdrawal times prior to shipping
Make proactive decisions to ensure early treatment or early culling to lead to better outcomes for the animal
Do not transport cattle with a Body Condition Score of 2 or less to reduce bruising, prioritize welfare and improve yield/payment
Mobility score 3 (using a 5-point scale) should be strongly scrutinized at the farm or auction market and evaluated for their ability to make the full trip to their end destination and in shape to walk into the processing plant
Full udders can cause animal discomfort and mobility issues, in addition to being a food safety concern since milk is considered a contaminant

With all fitness for transport and culling decisions, we should be asking ourselves, “What does it mean when the animal leaves the farm in that condition? Is this what is best for the animal?”

Euthanasia is also an important decision for which veterinarians should be a crucial adviser. Supporting producers in making euthanasia and culling decisions and developing protocols can help take the decision making away from the producer, making it easier to take that next step. For animals that should be euthanized rather than transported, ensuring landmarks are correct and maintenance of euthanasia tools are more steps to improving welfare. Considerations for carcass disposal should be weighed depending on what is available in the area and what is practical for the operation.

The Veterinarian’s Role
The veterinarian is key to the discussion, and can provide guidance and training on these topics.

It is important to recognize that cull cow marketing is rarely an all-or-nothing decision. There are nuances on each operation that the dairy farmer, employees and veterinarian should discuss when deciding to remove an animal from the herd. Cull cow management and marketing on the dairy is an important part of the business that deserves attention, rather than just serving as a byproduct from producing milk. Veterinarians are encouraged to use industry resources such as the “Right Way. Right Time. A guide to cull dairy cattle management” document, the National Dairy FARM resources at https://nationaldairyfarm.com/ , and the BQA program at www.bqa.org .

Insights into Calf Mortality at Commercial Calf Ranches

Fri, 24 Oct 2025 12:52:20 GMT

As the dairy industry embraces beef-on-dairy crossbreeding, a new type of animal is reshaping the U.S. calf and feedlot landscape. These calves, born on dairies but destined for the beef supply chain, are prized for their hybrid vigor, growth potential and carcass quality. Their journey often includes an early stay at commercial calf ranches, where young calves are reared in large groups under varying environmental and management conditions.

While these specialized facilities play a key role in raising thousands of calves efficiently, they also present unique animal health challenges. Calves arrive from multiple dairies, often within days of birth, and face stresses from transport, commingling and pathogen exposure. The industry has long suspected that respiratory disease dominates mortality at these sites, but until recently, detailed, systematic data to confirm those patterns were limited.

A new study by Rebecca Bigelow and colleagues from Kansas State University set out to change that. The study compiles data from over 240 necropsies performed across four different commercial calf ranches over a 12-month period documenting cause of death, concurrent conditions and whether these patterns shifted by season, sex, breed or location. These necropsies included both beef-dairy cross (152) and dairy calves (91). Their findings confirm respiratory disease is indeed the leading cause of death, but they also shed light on gastrointestinal (GI) disease and septicemia. Their work provides a valuable benchmark for working to improve early-life calf health.

Of the 243 necropsied calves, 67.5% of them had a primary diagnosis of respiratory disease. Gastrointestinal causes accounted for 11.5%, septicemia for 9.5%, and miscellaneous cases (including trauma, umbilical infection and liver abscesses) for the remaining 11.5%.

Most calves had no additional comorbidities recorded, but among those that did, respiratory plus another condition was the most common combination. Within the respiratory category, bronchopneumonia represented nearly 90% of cases, while bronchopneumonia with interstitial pattern was less frequent. Considering GI lesions, 49% of calves had no lesions, while 21% had upper GI lesions (rumen and abomasum), 13% had lower GI lesions (small and large intestine), and 30% had both.

One of the study’s more surprising findings was what didn’t change. Statistical modeling showed no significant associations between the likelihood of respiratory or GI diagnoses and season, sex, breed or ranch. This result suggests the underlying disease pressures in these systems are persistent year-round rather than being driven by environmental conditions or genetic background. Further, beef-dairy cross calves had no improved disease resistance compared to dairy calves under commercial rearing conditions.

These results can be summarized into the following takeaway points for animal caretakers:

Prioritize respiratory prevention.

With two thirds of deaths linked to respiratory causes, calf ranches must focus on preventative strategies: proper ventilation, gradual group transitions and consistent monitoring for early signs of respiratory illness. Review vaccination programs and align them for protection at times of stress and exposure.

Necropsies pay off.

Routine necropsy programs can help producers spot emerging disease trends before they escalate.

Maintain consistent management year-round.

Prevention and monitoring must remain equally rigorous through all seasons, not just in winter or transport peaks.

Collaborate across the production chain.

Calf health outcomes at ranches depend on colostrum management, navel care and nutrition practices at the dairy of origin, as well as transport and receiving protocols. Strong communication between dairies, calf ranches and veterinarians ensures continuity of care.

Preparing for the Battle Continues: USDA Shares Screwworm Update and Releases NWS Playbook

Mon, 20 Oct 2025 17:14:21 GMT

U.S. Secretary of Agriculture Brooke Rollins shared a New World screwworm update on X Sunday night.

“First and most important — No new cases have been detected in the last seven days in Mexican states bordering the United States,” Rollins says. “USDA and our partners continue to lead an aggressive response to New World screwworm (NWS). This is a national security threat, and it has the full attention of the Trump administration.”

Updates Rollins shared included:

Dispersing 100 million sterile flies per week in Mexico produced at the COPEG facility with more than 40 dispersal flights throughout Southern Mexico per week.
“USDA closely monitors the locations of detections in Mexico and ensures shipments of sterile insects and release chambers are routed to the locations of the latest detections for dispersal,” she says.
Inspecting wild or feral animals for NWS infestation as part of wildlife management activities in Texas, with more than 1,670 animals inspected to date.
Working with Mexico on trapping and surveillance.
“USDA staff have confirmed 7,885 total confirmed NWS cases in southern Mexico, an increase of 838 cases since Oct. 2,” Rollins reports. “There have been zero detections in border states since Oct. 5.”
Construction update: The NWS Sterile Fly Dispersal Facility at Moore Air Base will open in early 2026. This facility will allow USDA to disperse 300 million sterile flies weekly at the border and in northern Mexico.

NWS Playbook Released

Rollins says on Friday USDA hosted a call with more than 200 state partners and stakeholders to release the new USDA NWS Response Playbook .

“This playbook reflects our current approach and response if we ever have a confirmed positive NWS in the USA,” Rollins explains. “We want our state and industry partners to continue to provide feedback on ways to make the playbook even stronger.”

Industry stakeholders can provide feedback and suggestions regarding the playbook to FAD.PReP.Comments@usda.gov.

🚨 𝐍𝐖𝐒 𝐔𝐏𝐃𝐀𝐓𝐄 🚨

FIRST and most important — No new cases have been detected in the last 7 days in Mexican states bordering the United States.@USDA and our partners continue to lead an aggressive response to New World Screwworm (NWS). This is a national security threat…
— Secretary Brooke Rollins (@SecRollins) October 20, 2025

Playbook Highlights

According the playbook, the phases of the response include:

Preparedness — planning, organizing, training, equipping, exercising, evaluating and taking corrective action to ensure effective coordination during an outbreak response.
Confirmation, or NWS establishment in the U.S. due to NWS myiasis in warm-blooded animals or detection of NWS fly.
Containment, or preventing the spread of NWS in early stages of infestation through measures such as early detection, quarantines and movement requirements, sterile insect technique (SIT) and surveillance to reduce spread in domestic animals and wildlife.
Mitigation, or minimizing the outbreak impact, by reducing the geographic extent of the affected area to reduce strain on resources, achieved largely through quarantines and movement requirements, SIT and surveillance, and constant evaluation of impacted areas.
Control, or demonstrating infestation is being mitigated based on epidemiology and surveillance.
Eradication, or demonstrating freedom from NWS in previously affected areas.

If NWS is found in the U.S., USDA APHIS Veterinary Services will provide guidance, support, resources and coordination during an outbreak. The approaches and tools included in the playbook reflect USDA APHIS guidance and aim to provide a practical framework to rapidly focus on priority activities. Tools and resources will be updated regularly as new guidance on NWS is released.

Managing an NWS Response: Key Activities

(USDA APHIS)

The playbook includes eight key response activities:

Effectively manage a coordinated response and communications with stakeholders and the public
Reduce spread to non-infested animals and prevent NWS from establishing in new areas
Manage NWS on infested premises
Implement NWS surveillance and management strategies in wildlife
Implement NWS fly surveillance and management strategies
Maintain continuity of business (COB)
Ensure information flow and management
Identify and maintain resource requirements

How Three Ranches are Using Horses Today

Wed, 15 Oct 2025 18:28:37 GMT

The use of horses on the ranch is a tool that continues to be essential on many ranches today. Though it is a time-honored tradition for many, it is also how large ranches with diverse terrain manage daily cattle operations.

Horses are used in a variety of ways depending on the location and size of the ranch. At K4 Ranch, located 35 miles north of Prescott, Ariz., horses are used daily on their nearly 1 million acres where they manage cattle. In business since 1941, horses have been a staple to their functionality resulting in the addition of raising quarter horses.

“We raise a large number of horses to be used primarily for ranch work and secondly our production sale, The Legacy Ranch Horse Sale,” says Sarah Kieckhefer of K4 Ranches. “It is very important to us to raise performance horses that we use first and foremost as ranch horses for a solid foundation before we go into the arena or for breeding.”

Using horses to check and gather cattle is typically their only option with the rugged terrain.

“We use horses for everything involving cattle,” Kieckhefer says. “Our country in Arizona and California is rough terrain with mountains and ravines so motorized vehicles just don’t work.”

Their Diamond A Ranch, a division of K4 Ranch is the largest ranch in Arizona, running their largest number of cows and employs a large crew with seasonal cowboys and eight camps with full-time cowboys. They also have ranches in California and Oklahoma that they run cows and stocker cattle on.

“On our large ranches with rough or brushy terrain, a good horse can go where a pickup, ATV or side-by-side can’t,” Kieckhefer explains. “Horses can cover long distances, cross canyons and handle steep or rocky country, and a horse allows you to move quietly, ease cattle along and reduce stress, which leads to fewer wrecks and better weight retention.”

Gathering and Sorting

Poss Angus, a registered Angus operation in Scotia, Neb., uses horses to gather, sort and pull heats during the breeding season. In the summer months they doctor and gather cattle on grass.

“Most of our pastures are rough clay hills with ponds and trees, so having a horse to get to where the cows are is definitely necessary,” says Nathan Poss, head cowboy. “Ninety percent of the time, if there is cattle work being done of any kind, there is a horse or two being saddled.”

Poss Angus manages roughly 800 head with a bull sale every February and occasionally a female sale in the fall.

“I don’t typically use a horse in the picture pen but always to video bulls,” Poss adds. “By using a horse in the video pen, it is easier to move the bulls back and forth across the pen. Videoing can also turn into a long couple days, so it’s nice to have a young horse putting in the steps instead of me.”

Poss’ main responsibilities are the health and care of the cattle, including feeding, doctoring, calving and processing.

“I enjoy taking the ranch work and utilizing it to make young horses better through the work. Another great benefit in my mind is when working cattle horseback, the cattle gain respect for you and your horse, over time I feel like those cattle work and handle much easier,” Poss explains. “In my opinion, if it comes down to catching a single animal, a horse must be used. By using a horse instead of a four-wheeler, it keeps the environment quiet, and you can always go the same pace as the animal to help steer them in the direction you need to go. Four wheelers and rangers are also used very heavily on our ranch. Quickly moving a group to another pasture, tagging, putting out salt and mineral, those are all equivalent times to use a four-wheeler or ranger.”

Branding and Moving

The Pitchfork Ranch in Meeteetse, Wyo., uses horses heavily during branding seasons and moving cattle on and off mountain pasture. Primarily a commercial cow-calf operation focused on pounds of beef produced per acre, they also retain some cattle every year for their beef program that sells directly to consumers.

Their cattle have to thrive at elevation and harsh winters, then range calve in the spring. The Pitchfork Ranch also hosts an annual ranch horse sale in the spring.

“We use horses in all of our cattle work. In the spring we calve in an 8,000-acre pasture where we then pair cattle out into our branding groups,” says Lindsey Anson, who manages The Pitchfork Ranch. “We head and heel calves at branding and then start working our way up country where cattle summer at 10,000' elevation in the Absaroka range. In the fall as cattle come off the mountain, they are then paired out again horseback into contemporary sex groups until we ship in the first half of November.”

Similar to K4 Ranch and Poss Angus, using horses is often because of the terrain.

“Our terrain also doesn’t allow for the use of motorized vehicles very often so the work has to be done on a horse. Part of our summer range is also in a wilderness area where we still have to pack in salt and mineral horseback,” Anson explains. “Our cattle seem to handle better horseback. In the subtleties of reading cattle, you can make minor adjustments on horseback that you aren’t able to do with something motorized.”

How Certified Veterinary Technicians Can Strengthen Your Cattle Practice

Mon, 13 Oct 2025 19:40:10 GMT

Oct. 12-18, 2025, is National Veterinarian Technician Week. This is the perfect time to celebrate some of the most versatile, hard-working, and essential members of the veterinary world or consider whether having a credentialed veterinary technician (CVT) could be good for your practice.

In cattle practice, where every day brings a new challenge — from calving complications to herd health checks and emergency calls miles down the road — CVTs bring structure to the chaos. They’re the steady hands that keep the work moving, the organized minds behind the paperwork, and the friendly faces clients often see first.

But beyond the appreciation posts and coffee gift cards, this week is a good reminder to ask a bigger question: How could a veterinary technician make your practice stronger?

The Value of CVTs

Cattle veterinarians wear a lot of hats. On any given day, they might manage herd health programs, run regulatory testing, deliver calves, diagnose lameness and field a few “while-you’re-here” questions about nutrition. It’s a demanding mix of clinical skill, logistics and endurance.

A skilled CVT helps shoulder that load. Under proper supervision, technicians can collect samples, assist with treatments, monitor anesthesia, record data, maintain biosecurity and help keep visits efficient and thorough.

That support means veterinarians can spend more time where their expertise is most valuable: making diagnoses, planning herd strategies and strengthening client relationships. It’s not just about saving time; it’s about elevating care.

Recognizing the growing role of technicians in food animal work, the American Association of Bovine Practitioners (AABP) released new Guidelines for Credentialed Veterinary Technicians in Bovine Practice in 2024.

The goal? To help practices use CVTs safely, effectively and confidently.

The guidelines outline:

Clear definitions. They distinguish CVTs from assistants.
Task lists and supervision levels. Each procedure — from sample collection to post-operative care — includes a recommended level of supervision (direct, indirect or veterinarian-only).
Built-in flexibility. They’re not meant to limit what practices do but to encourage veterinarians and techs to sit down together and ask, “Where can we work smarter?”

These guidelines are meant to open the door for team discussions about how to delegate tasks responsibly while improving efficiency and morale.

Lessons from the Field

At the 2025 AABP conference, Oberlin McDaniel of NC Mobile Veterinary Service emphasized something every good cattle practice knows instinctively: Teamwork is everything.

Many large animal practitioners are operating solo practices, meaning performing every task personally. This could lead to inefficiencies, missed revenue opportunities and physical and mental fatigue.

McDaniel pointed out that CVTs could contribute greatly to data flow in modern herd management. Whether entering lab results, tracking treatments or uploading records, technicians keep the information stream accurate and actionable — a key edge for practices embracing digital herd health platforms.

The return on investment is also a significant concern for veterinarians. Research has shown that the use of CVTs in small and mixed animal practices can increase revenue by 14% and increase veterinary productivity by 17%. In this work, 25% of the mixed animal practices were primarily bovine. The USDA Veterinary Services Grant Program is also available to support technician training and retention in underserved areas.

Perhaps most importantly, McDaniel emphasized that better technician integration isn’t just about doing more work, it’s about doing better work. When CVTs handle routine or preparatory tasks, veterinarians have time to consult more deeply with producers or tackle complex cases. Everyone wins, especially the cattle.

How Could a CVT Improve Your Practice?

If you’re not sure where to start, consider these benefits:

More visits, less rush. With a CVT preparing samples, logging data and managing restraint, veterinarians can cover more ground, literally and figuratively.
Better preventive care. CVTs can lead vaccination, sampling or deworming programs, improving consistency and compliance.
Stronger communication. CVTs can provide an enhanced client experience with more responsive communication. Techs help reinforce messages and build trust.
Cleaner data, better records. From digital uploads to treatment logs, accurate data makes your job easier. Having a CVT could streamline this process.
A happier, more sustainable practice. Delegating appropriately prevents burnout, improves job satisfaction and keeps teams motivated.

Practices that invest in training and trust see higher productivity and stronger team retention, two things every rural practice could use more of.

Celebrating and Empowering Vet Techs

National Veterinarian Technician Week is a great time to thank your technicians, but the best way to celebrate them is by giving them the professional recognition and responsibility they’ve earned. A well-utilized CVT doesn’t just make your day easier, they make your practice stronger, your clients happier and your herd care better.

So this October, take a moment to recognize the hands, minds and hearts that keep your practice moving forward and ask yourself how you can help them do even more.

Winter: The Secret to Slowing the Spread of Screwworm

Thu, 02 Oct 2025 11:03:28 GMT

Winter or colder temperatures — it’s not something you typically hear livestock producers anticipating or praying for. But this year, as the threat of New World screwworm continues to inch closer to the U.S.-Mexico border, winter can’t come soon enough.

“Certainly, winter will be our friend,” says Chris Womack, a veterinarian and rancher from San Angelo, Texas. “Historically the flies were pushed south with frost.”

USDA Agricultural Research Service entomologist Kim Lohmeyer agrees we need winter to come fast. Lohmeyer serves as the laboratory director of the Knipling-Bushland U.S. Livestock Insects Research Laboratory in Kerrville, Texas, where she and her colleagues use modeling to know when and where NWS may show up in the U.S. They are partnering with Lee Cohnstaedt and his team at the National Bio and Agro-Defense Facility in Manhattan, Kan., to study the life stages of NWS and its susceptibility to temperature and weather.

“With the climate changes and weather patterns we have now, if this fly gets here, it can go a lot further north, a lot further east and a lot further west,” Lohmeyer says. “It’s something to keep an eye on.“

The Winter Win

So, what exactly does “winter” mean? Lohmeyer says NWS are fairly cold sensitive, so several days of sustained cold temperatures in around 30°F would be enough to suppress NWS.

The NWS’s ability to survive is restricted to locations where low temperatures are regularly above freezing. Ideal adult fly activity occurs at 77°F to 86°F and relative humidity of 30% to 70%.

“This fly really loves 81.5°F,” explains meteorologist Matt Makens. “The research shows that’s when they’re friskiest.”

Although the Sterile Insect Technique (SIT) remains a primary control mechanism, Makens says studies have made it clear that eradication success, outbreak intensity and re-emergence potential are closely tied to weather and climate.

“From seasonal wind patterns to monsoonal moisture, numerous environmental conditions shape the life cycle, spread and population dynamics of this parasite,” Makens explains. “Understanding these weather-related drivers is critical not only for control, but also in considering how long-term temperature trends have altered the geographic boundaries of screwworm viability since the major outbreaks of the 1950s and early 1960s.”

During a recent Cattlemen’s Call podcast Makens said weather is one of the main forces of spreading NWS.

“If we could control the weather, we could control the fly,” he stresses.

Research indicates larval and pupal development cannot proceed below approximately 58°F and halts above 110°F. The optimal temperature for adult survival and reproduction lies around 81.5°F, a range common in tropical and subtropical climates like Mexico and Central America. NWS do not survive in regions with cold winters, though they may spread into these areas during the warmer months.

Impact of temperature on NWS:

Reduced activity: Adult screwworm fly activity is limited when temperatures are below 59°F.
Larval vulnerability: Pupae are vulnerable to soil temperatures below 46°F. Sustained maximums hotter than 95°F can also be limiting — extreme heat reduces adult fly activity and increases mortality in larvae exposed to hot surface soils.
Life cycle: While the entire life cycle can be completed in warm conditions, it takes longer in cooler, more temperate environments.

“One of the secrets to historically, the northern limit of screwworm, was basically a matter of how cold the winter got. That sort of limited how far it got,” says Derrell Peel, Oklahoma State University Extension livestock marketing specialist. “In years when it was warmer, it would go farther. It would overwinter farther north, but in general, that’s going to set the upper limit, or at least it does if it’s not under control in any other way. That will limit its northward, northern movement, for sure.”

Fly Season

David Anderson, Texas A&M professor and Extension specialist, says, historically, the fly season is April to October.

“If we get a really cold winter, that helps us,” Anderson adds. “It buys us some more time. But things are warmer now than it used to be. Fly season may not be that April to October anymore.”

NWS’s typical life cycle lasts about 21 days in warm weather and slightly longer in cooler climates. According to Texas A&M AgriLife Extension Service, NWS fly life cycle is highly sensitive to temperature:

In warm (more than 80ᴼF daytime highs) and tropical conditions, the full life cycle may be complete in two to three weeks.
In more temperate conditions, the life cycle may take three to four weeks.
In cooler conditions, the life cycle may take up to two to three months.

It is important to understand that the flies do not die at these lower activity temperatures, but prolonged exposure to these temperatures can reduce populations or active infestations.

Texas rancher Wayne Cockrell says NWS’s entry into the U.S. is inevitable but suggests winter and colder weather might temporarily delay the spread until next April or May. Cockrell serves as the Southwestern Cattle Raisers Association director and chair of the cattle health and well-being policy committee.

“We should be within 60 days hopefully when cold weather helps in two-thirds of the state,” Cockrell explains.

Rainfall and Monsoon Factors

Makens says while temperature defines where screwworms can survive, rainfall and moisture influence when and how intensely they can thrive. Outbreaks often follow moderate to heavy rainfall by improving conditions for larval survival.

He explains tools like the Palmer Crop Moisture Index (CMI) have shown promise in predicting screwworm risk, with higher-than-normal CMI values sometimes preceding population spikes.

When rainfall coincides with favorable temperatures, screwworm activity tends to increase. In contrast, hot and dry conditions tend to suppress survival and reproduction.

“One of the most striking climate connections is the role of seasonal monsoon winds in transporting screwworms over long distances,” Makens explains. “In multiple outbreak years, adult flies were documented migrating northward into Texas and the desert Southwest via the North American Monsoon (NAM) — a seasonal pattern that delivers moisture to northwestern Mexico and the U.S. Southwest from June through September. During the summer, prevailing winds shift from west to a more humid, southerly flow, creating favorable conditions for fly migration from central and southern Mexico into their northern states and, at times, into the southern U.S. The NAM this year had an early start and gave significant rainfall to parts of Arizona and New Mexico. The NAM typically calms by early fall.”

In the 1960s, these wind-assisted movements allowed the temporary re-establishment of breeding populations even after local eradication. In some years, migration spanned hundreds of miles, connecting source populations in northern Mexico to re-infestations in Arizona and New Mexico.

“This atmospheric ‘conveyor belt’ remains a critical concern in surveillance strategies for livestock-producing regions of the Southwest,” Makens says. “The 2025 monsoon was undoubtedly a factor in the most recent northward migration of NWS.”

If NWS should cross the border, it will be key for producers to coordinate management practices with weather patterns expected for their region.

“Ultimately, weather patterns act as both a barrier and bridge for screwworm activity,” Makens summarizes. “Knowing how and when the balance tips is essential to preventing the return of one of the industry’s most damaging parasites.”

Here’s to hoping Old Man Winter decides to arrive quickly and help buy livestock producers and government leaders more time to prepare to battle NWS.

Rural Voices, Federal Ears

Tue, 30 Sep 2025 20:55:25 GMT

USDA recently hosted the two listening sessions aimed at stakeholders interested in shaping the Rural Veterinary Action Plan, announced by U.S. Secretary of Agriculture Brooke Rollins late in August, which seeks to address long-standing shortages in rural food-animal practice and to strengthen the federal veterinary workforce. They hoped to gather input on the challenges facing the rural veterinary workforce that could be used to shape the next steps of the plan. These sessions provided an opportunity for producers, veterinarians, educators and professional organizations to share their perspectives directly.

USDA members first outlined the current rural veterinary landscape before opening the floor to stakeholders who were given a short time to present while USDA representatives listened.

The backdrop of these sessions is a well-documented and worsening shortage of veterinarians in rural areas, particularly those serving in food-animal and mixed practices. Certain regions of the country face critical gaps, leaving producers without timely access to veterinary care and threatening both animal health and food supply security. These shortages are shaped by economic factors along with geographic demands.

Overview of Top Concerns

Stakeholders spoke on a variety of concerns and priorities spanning financial, educational, regulatory and logistical themes.

There were several main issues that multiple stakeholders brought up during these sessions:

Lack of veterinary students from rural locations

There exists a difference in education quality in rural versus urban areas, including a lack of availability of AP classes. This compounds into poor preparation for university resulting in lower grades and a lowered chance for admittance into vet school. The lack of a uniform vet school application process was also highlighted, specifically whether an interview was required. Students with lower grades would benefit more from an in-person interview to show their passion and intent.

“There are simply not enough rural kids getting accepted to vet school,” said Dr. Tracy Walker of West Virginia. “I’ve sat with different acceptance committees. When you look at the calculations of how they’re scoring these kids, rural kids are at a complete disadvantage.”

Complicated grant application process

Federal grant applications can be cumbersome and time consuming. Stakeholders suggested streamlining and simplifying this process, along with being clear about what portions of these grants would be taxable.

“As a Veterinary Medicine Loan Repayment Program recipient last year, my application was 80 pages long,” said Dr. E Sabo, the assistant state veterinarian for Utah. “If I were still in private practice where I used to be a dairy veterinarian, I would not have had the time and ability to fill out an application of that length. I started two months early and did not have the full application completed by the deadline.”

Overhead costs for starting a practice

Because of the sparse distribution of rural veterinary practices, most students would be opening their own business following graduation. This can be very daunting for graduates also managing student loans.

“If we want to set new veterinarians up for success in rural settings where revenue is often lower and practice costs are higher, we must match their passion with practical, long term support,” said Cheryl Day, executive vice president of the Ohio Pork Council. “We need federal tools that help veterinarians start and sustain practices in underserved counties including startup grants, low interest loans and a catalog of resources.”

Student debt

Compounding the costs of startup for a new graduate is the need to repay any student loans. There is a significant salary gap between rural food-animal practice and companion animal medicine. This disparity can make small animal practice appear more financially viable for new graduates carrying substantial financial burdens.

“Debt relief remains one of the most consistent ways of offsetting salary discrepancies between rural and urban practices,” said Fred Gingrich, executive director of the American Association of Bovine Practitioners.

Takeaways

These sessions showed USDA’s commitment to improving the situation for rural veterinarians. Whether the outcome is incremental change or significant investment, USDA is paying attention to a crisis that affects animal health, producer livelihoods and food security, and it is listening to the rural veterinary workforce to shape policy.

FDA Approves Dectomax-CA1 for Prevention and Treatment of New World Screwworm

Tue, 30 Sep 2025 19:04:12 GMT

Today, the U.S. Food and Drug Administration conditionally approved Dectomax-CA1 (doramectin injection) injectable solution for the prevention and treatment of New World screwworm larval infestations, and prevention of NWS reinfestation for 21 days.

According to Zoetis, this conditional approval applies to beef cattle, female dairy cattle less than 20 months of age, pregnant beef cows, newborn calves and bulls.

“We understand the urgency with which America’s farmers and ranchers are asking for tools to fight New World screwworm,” says FDA Commissioner Marty Makary, M.D., M.P.H. in a press release . “Today’s conditional approval – the first in the U.S. for NWS – shows our dedication to rapidly advancing important animal medicines when they are needed most. We continue to work tirelessly to complete review of other NWS products to protect multiple animal species in the U.S.”

Dectomax-CA1 is eligible for conditional approval because it is intended to prevent and treat a serious or life-threatening disease in cattle, it addresses an unmet animal health need, and demonstrating effectiveness of the drug would require complex or particularly difficult studies.

“Under this conditional approval, the FDA has determined the drug is safe and has a reasonable expectation of effectiveness. We are making this treatment available to cattle producers immediately while the sponsor collects the data needed for a full approval,” says Timothy Schell, Ph.D., acting director of the FDA’s Center for Veterinary Medicine. “The FDA will continue to expedite review of animal drugs to help the U.S. fight this devastating threat to our nation’s livestock and the livelihoods of the farmers and ranchers who care for them.”

Dectomax is already fully approved under a New Animal Drug Application for treatment and control of certain nematode and arthropod parasites in cattle and swine. Dectomax and Dectomax-CA1 contain the same active ingredient (doramectin injection) at the same dose. Because the original approval of Dectomax included adequate target animal safety studies, manufacturing information, and human food safety information, the FDA did not require new information to support those aspects for the conditional approval of Dectomax-CA1.

“New World screwworm has the potential to bring unprecedented economic and animal health harm to livestock producers,” says Mike Lormore, DVM, MS, MBA, director of cattle and pork technical services at Zoetis. “Our top priority is to support keeping animals healthy and provide timely, efficacious solutions to our customers and partners. With this conditional approval, Dectomax-CA1 Injectable can now be used as part of safe, effective control measures against New World screwworm.”

The withdrawal period for cattle is 35 days for Dectomax-CA1, as it is for Dectomax. Warnings to prevent drug residues in meat from treated cattle are the same for Dectomax-CA1 as for Dectomax: Not for use in female dairy cattle 20 months of age or older. A withdrawal period has not been established for this product in preruminating calves. Do not use in calves to be processed for veal.

In the first half of 2026, producers and veterinarians will begin to see the 250-milliliter and 500-milliliter bottles of Dectomax Injectable with a new label for Dectomax-CA1 (doramectin injection). Dectomax-CA1 is the same effective doramectin formulation as Dectomax Injectable. Dectomax-CA1 label will contain both Dectomax and Dectomax-CA1 indications while each drug has a unique application number.

To reduce the risk of antiparasitic resistance and preserve drug effectiveness against other parasites, producers and veterinarians are encouraged to use antiparasitic drugs like Dectomax-CA1 only when medically necessary, in accordance with the product labeling, and as part of a comprehensive parasite management strategy.

Livestock producers are encouraged to work closely with their herd veterinarian to implement strategic prevention and control measures. Visit Zoetis’ website for more information about Dectomax-CA1.
