Calving

Calf Survival Tips For Before, During and After Birth

Tue, 31 Mar 2026 17:13:09 GMT

Most discussions around calf loss begin at calving. But by then, much of the outcome has already been set in motion.

Across veterinary perspectives from different production environments, a consistent picture emerges. Calf outcomes are shaped over time, influenced by a series of decisions and conditions that build on one another.

It is important to note these patterns may look different depending on region — whether driven by cold stress, heat, drought or mud. The underlying process, however, remains consistent across systems.

Before Birth: Build Resilience Early

Calf outcomes begin to take shape during gestation. Nutrition, stress and overall maternal management all contribute to how the calf develops before it is ever born.

“Poor nutrition of the cow is a stress on the fetus … any stress on the cow can affect the development of the placenta and also of the calf,” says Dr. Katie Waine, veterinary pathologist at the University of Calgary. “Maternal stress around breeding and pregnancy can also have much longer-term effects on calf health, production and reproductive performance way off into the future.”

This concept, known as fetal programming, highlights how early conditions influence organ development, immune function and long-term performance. Calves may appear normal at birth while still benefiting from stronger developmental foundations established during gestation.

Key risk factors before birth include:

Inadequate maternal nutrition or poor body condition
Environmental or physiological stress during gestation
Inconsistent feed quality
Health challenges
Gaps in vaccination or biosecurity planning

Nutritional management during gestation plays a central role in setting the foundation for calf health. Cows entering calving in appropriate body condition are better positioned to support both fetal growth and colostrum quality. Reducing stress during pregnancy further supports placental function and fetal development. Consistent feed quality, stable environments and proactive health management all contribute to a stronger starting point for the calf.

At Birth: Support a Strong Transition

Calving represents a key opportunity to support the calf’s transition into early life. While it can reveal existing vulnerabilities, it also provides a chance to reinforce resilience.

“The effects of a difficult calving don’t stop at birth — they carry forward into immunity, vigor and overall survivability,” says Dr. Lisa Freeze, field veterinarian supervisor with the Government of New Brunswick.

A smooth calving process helps calves stand, nurse and absorb colostrum more effectively. Timely intervention when needed can prevent minor challenges from becoming larger setbacks.

“When calves are delayed during calving or we have to intervene late, they’re already starting life at a disadvantage,” Freeze says.

Key risk factors at birth include:

Prolonged or difficult calving (dystocia)
Delayed standing or nursing
Inadequate or delayed colostrum intake
Early-life stress or trauma

Focusing on calving ease, monitoring progress and ensuring early colostrum intake all support a stronger start. These early actions directly influence immune transfer and overall vigor.

“What we see with the sickness and death of calves all depends on how much pathogen they get exposed to and how resistant they are to it,” says Dr. Van Mitchell of Metzger Veterinary Services.

Supporting resistance through colostrum and minimizing early stress helps calves respond effectively to their environment.

After Birth: Manage Exposure and Reinforcing Success

After birth, management focuses on maintaining the balance between exposure and resistance. Even well-prepared calves benefit from environments that support their continued development.

In practical settings, multiple factors often interact. Recognizing these interactions allows producers to stay ahead of potential challenges.

“It’s rarely just one thing. A calf that struggles at birth, doesn’t get enough colostrum, and then is exposed to a challenging environment — those risks stack on top of each other,” says Dr. Allison Pylypjuk of Beausejour Animal Hospital.

Dr. Lauren Wilson of Peterborough Veterinary Services agrees: “Those calves that don’t receive adequate colostrum are much more susceptible to disease, and when you combine that with environmental exposure, that’s when we start to see problems like scours and pneumonia.”

The same principle applies in a positive direction. When calves receive timely colostrum, experience minimal stress at birth and are raised in clean environments, those advantages build as well.

Key risk factors after birth include:

High pathogen load in calving or housing areas
Overcrowding or poor stocking density
Mixing age groups, especially older calves with newborns
Delayed identification and isolation of sick animals

Clean calving areas, appropriate stocking density and thoughtful grouping strategies help limit pathogen exposure. These practices support calves as they continue to develop immunity and resilience.

“We can eliminate a lot of exposure to the pathogens by keeping our calving areas clean, keeping the sick animals away,” Mitchell says.

Managing these factors helps maintain momentum established earlier, allowing calves to continue on a positive trajectory.

A Proactive Approach to Calf Survival

Viewing calf outcomes as a cumulative process creates more opportunities for intervention. Each stage — before birth, at calving and after birth — offers a chance to support the calf’s success.

Rather than focusing only on problems after they appear, this approach emphasizes building resilience early and reinforcing it over time. The goal is not to eliminate all challenges, but to create conditions where calves are better prepared to respond. Consistent management, early attention and thoughtful decision-making all contribute to improved outcomes.

Calf survival is not determined in a single moment. It develops step by step, shaped by a series of actions that build on one another from gestation through early life.

Is Your Dystocia Kit Ready?

Thu, 19 Feb 2026 15:11:35 GMT

Calving season rarely unravels because of one catastrophic mistake. More often, it is delayed recognition, repeated unproductive pulling or the one missing tool that turns a manageable dystocia into a wreck.

A ready dystocia kit is not just a bucket of equipment sitting in the barn office. It is timing, facilities and a clear decision tree that guides what happens when progress stalls. Caitlin Wiley, clinical associate professor at Iowa State University, outlines what you should consider including in your dystocia toolkit.

Start With Time, Not Tools

Before a chain ever goes on a leg, producers and veterinarians should share clear expectations about how long is too long.

Stage one of calving, the initiation of labor through the appearance of the water bag, lasting more than 12 hours warrants concern. Stage two, when the calf should be delivered, extending beyond an hour, and certainly two hours, should prompt intervention.

Wiley advises regular check-ins to ensure things are on track.

“Give yourself 15 to 20 minutes of doing whatever you’re attempting to do. Are we making progress? If not, reassess. If we’re not making progress, what’s our next best step?” she says.

Repeated traction without advancement is not persistence. It is lost opportunity, and often escalating trauma. Clear timing protocols belong in your kit just as much as chains and lubricant, because they determine when you change course rather than double down.

Build a Kit That Extends Your Reach

A functional dystocia kit should be assembled and inspected in preparation for calving.

These are the items Wiley recommends keeping in your kit:

Multiple long OB chains
A wire introducer for placing chains in deep or awkward cases
A head snare or extra chain that can function as one
A calf jack for controlled traction
Ample lubricant, preferably carboxymethyl cellulose based
Suturing material in case of hemorrhage
An oro-gastric tube and a separate stomach tube
A stomach pump
Appropriate drugs, including epidural agents and uterine relaxants
A speculum
A halter for improved restraint

This list is not exhaustive, and individual practice style will shape it further. The key principle is simple: your tools should extend your reach and options, not limit them because something essential was forgotten.

Facilities Are Part of the Kit

Equipment cannot compensate for poor setup. Facilities shape outcomes long before traction begins.

An open-sided chute that allows access from both sides improves both efficiency and safety. A halter tied forward can help prevent repeated setbacks when cows attempt to lie down mid-manipulation. Small adjustments in positioning and restraint often reduce the physical strain on both the cow and the person assisting.

When facilities allow you to evaluate, reposition and reassess without chaos, decision-making improves.

Confirm the Three Ps Before You Pull

Before committing to sustained traction, slow down long enough to confirm your three Ps.

“Position, posture, presentation,” Wiley says. “If you miss those pieces, you can spend a lot of time trying to pull something that’s not going to work.”

Engage the legs into the pelvis before applying force. If you cannot fit your hand between the calf and the pelvis, that observation matters. Continuing to crank without engagement increases trauma and fatigue and rarely improves the outcome.

Backward calves, twins and head-back presentations each demand deliberate assessment before force is applied. In many cases, the decision to pivot starts with recognizing engagement is not happening.

Know When to Change the Plan

There is a point where traction becomes counterproductive.

“I think sometimes we look at C-sections as a fail, and I argue it’s not. It’s a good, valid option. Sometimes the sooner decision becomes the better outcome we have for our cows and our calves,” Wiley says.

The goal is not to prove you can get a calf out vaginally. The goal is viability and recovery.

Changing the plan is not an admission of defeat. It is clinical judgment.

Debrief Every Case

After each dystocia, take time to reflect on what happened, even briefly.

“Regardless of how it comes out, ask, ‘Can we do something different? Can we work on this?’” Wiley suggests.

Was the call delayed? Were timing expectations unclear? Was there a moment when reassessment should have come sooner?

Dystocia will always be part of cattle practice. But incomplete kits, delayed reassessment and reluctance to pivot do not have to be. A ready kit is preparation in both equipment and judgment, and both matter when minutes count.

Does Supplementing Bred Heifers Increase Calving Difficulty?

Sat, 14 Feb 2026 00:27:46 GMT

Producers are often told supplementing bred heifers with protein prior to calving increases calf birth weight and leads to greater calving difficulty.

According to Paul Beck, Oklahoma State University (OSU) Extension beef cattle nutrition specialist, nutrition of bred heifers during gestation does have lasting consequences for both the calf and the future productivity of the cow.

“Decades of research clearly demonstrate that maternal undernutrition during pregnancy negatively influences not only the cow’s reproductive performance, but also immune transfer, calf survival, weaning weight and post-weaning performance,” he says.

Research conducted in the 1970s at OSU compared productivity of heifers managed to achieve either adequate or obese body condition from 12 months through 5 years of age. At first calving, 58% of the obese heifers required calving assistance, compared with only 8% of heifers at adequate body condition. These data are the basis for current recommendations that heifers calve at a body condition score (BCS) of approximately 6, but not reach a fleshy (BCS 7) or obese (BCS 8) condition.

Energy and protein supply during late gestation can influence calf birth weight, Beck summarizes. Research by Corah and colleagues published in 1975 demonstrated heifers restricted to 65% of energy requirements during the final 100 days of gestation produced calves approximately 4.4 lb. lighter at birth. However, these calves experienced greater neonatal mortality and reduced weaning rates compared with calves from adequately fed dams. Importantly, lighter birth weight was not associated with reduced calving difficulty, illustrating how undernutrition compromises calf viability rather than preventing dystocia.

“Restricting nutrients prior to calving weakens both the cow and the calf, increasing calving difficulty and reducing calf survival,” Beck summarizes.

Kansas State University’s Jaymelynn Farney says restricting heifer diet in the last trimester can result in potentially lower quality and quantity of colostrum , reduced absorption of immunoglobulins from colostrum potentially driven by weaker calves that were slower to nurse, an increase in calf scours and a reduction in overall weaning weights.

Birth weight responses to precalving supplementation are highly variable. Beck evaluated changes in calf birth weight reported from 24 studies evaluating late-gestation supplementation.

“The average increase in calf birth weight was only 3 lb., with responses ranging from a 3 lb. decrease to a 10 lb. increase,” he reports. “The largest increases occurred when high levels (approximately 5 lb. per day) of energy-dense supplements were fed.”

Fifteen of these studies also reported subsequent pregnancy rates. Although variable, the average pregnancy rate of unsupplemented cows was 86%, compared with 92% for cows supplemented during late gestation, with the greatest response observed in first-calf heifers.

Excessive energy intake during late gestation partitions more nutrients toward fetal growth, resulting in larger calves. When coupled with excess fat deposition in the pelvic region, this increases the risk of dystocia. Thus, excessive energy, rather than protein supplementation alone, is the primary contributor to increased calving difficulty in many heifer programs.

Ensuring bred heifers meet — rather than greatly exceed — energy and protein requirements, promoting moderate BCS gain during mid and late gestation and strategically supplementing key nutrients improves calf survival, preweaning growth, immune function and long-term reproductive performance without increasing calving difficulty.

“Avoiding maternal undernutrition remains one of the most consistent strategies for improving whole-herd productivity and profitability,” Beck summarizes.

What Causes Calving Difficulty?

Farney says there are multiple reasons calving difficulty can occur, which may include the calf being too big, pelvis too small, abnormal presentation, lack of uterine contractions, fatigue or twins.

“Abnormal presentations cannot be eliminated by genetic selection or nutritional management, so be prepared for these scenarios a minimum of three weeks before your first calf is expected,” says Farney, a beef systems specialist.

Calf birth weight is often blamed as the sole culprit of calving issues.

“Calf birth weight can be affected by several factors — genetics, gestation length and, to an extent, dam nutrition,” Farney summarizes. “High calving ease sires typically have a shortened gestation length, hence the reason that most of those calves are a bit lighter in weight.”

She says on average, calves will gain between 1.5 lb. to 2 lb. of body weight in late gestation. For example, if the average gestation length is 283 days and a calf is born a week early, it will often weigh 10 lb. to 14 lb. less.

She adds dams that experience cold stress in the last trimester may have calves that are heavier in weight.

“Typically birth weights are greater for calves born in the spring or winter as compared to fall-born counterparts,” she says. “A Nebraska study that evaluated six years of data found for each 1° F lower than the average winter temperature (December through February) calf birth weight increased 1 lb.”

The increase in birth weight is most likely due to the needed increase in nutrient flux through supplementation to offset cold stress events.

“Now you might think, it is a cold winter and I do not want to deal with calving problems, so I will just make that cow survive on the same diet she has been on and not account for added maintenance requirements due to cold stress,” Farney says. “That thought will lead to a plethora of other issues that can extend through that calf’s entire productive life.”

She stresses it is important to appropriately balance a diet for first-calf heifers.

“Don’t starve the calving difficulty out of your heifers,” Farney summarizes. “These heifers need appropriate energy to help with the birthing process or they will quit on you as they just run out of steam going through parturition. Additionally, the calves need enough energy to quickly get up and nurse, and if dam energy is restricted, calves will be lethargic. Proteins are essential for colostrum quality, which has major lifetime effects on that calf.”

3 Nutritional Questions to Consider Prior to Calving

Fri, 16 Jan 2026 14:45:05 GMT

Supplying adequate nutrition to the cow is critical during the 60 days prior to calving and immediately after calving.

“Beef cattle can turn high fiber forages and food by-product residuals into protein food at a very effective rate,” says John Comerford, Pennsylvania State University professor emiritus of animal science, in a recent extension article . “For the cow herd, there is seldom a period during the year when the cow cannot meet her nutritional needs with reasonable quality grass, hay or stored forages. The exception for these nutritional needs is for the 60 days prior to calving and immediately after calving.”

Why Is There a Nutritional Challenge Prior To and After Calving?

Comford explains there are three major reasons why cows are challenged prior to and right after calving:

The initiation of lactation
The return to a fertile reproductive state
The production of colostrum

He adds the cow’s age has an impact on these factors, and younger cows have more critical nutritional needs.

Lawton Stewart, University of Georgia (UGA) assistant dean for extension, and Uttam Saha, UGA Agricultural & Environmental Services Lab (AESL) program coordinator, explain there are three nutritional questions producers should consider as calving season approaches — depending on forage availability and quality.

Does restricting feed in the last trimester decrease calf birth weights?
Do you need more protein to go with hay?
Are you underestimating crude protein and overestimating energy?

Does Restricting Feed in the Last Trimester Decrease Calf Birth Weights?

Stewart and Saha say yes, feed restriction will decrease birth weights. The problem is that birth weight is not the only thing it will affect.

Recent research has focused on fetal programming . Fetal programming is the concept that maternal stimuli or insults during fetal development have long-term effects on the offspring.

One of the most critical aspects of fetal programming involves the adequate nutrition, or lack thereof, of the dam. Research has shown minimal impact on calf birth weights; however, the restricted nutrition during the last trimester decreased weaning weights, finishing weights and hot carcass weights.

Additionally, research from Nebraska indicates heifers from nutritionally restricted cows reached puberty 14 days later than those with proper nutrition.

Do You Need More Protein to Go with Your Hay?

Stewart and Saha say possibly, however, protein is only half of the equation.

Figure 1: The nutrient requirement of a mature brood cow through a 365-day calving interval.

(UGA)

From April 1 to Oct. 1 of 2025, 773 bermudagrass hay samples were submitted to the UGA lab. The mean crude protein (CP) and energy (TDN) value was 11.1% and 55.7%, respectively. The illustration above represents the CP and TDN requirements of a brood cow throughout the production year. As cows enter the final trimester, their CP requirement is exceeded by the average bermudagrass sample, but the energy requirement falls short. More importantly, as they calve, enter peak lactation and the breeding season, the CP requirement is met, but the TDN falls tremendously short.

Do Producers Underestimate Crude Protein and Overestimate Energy?

Stewart and Saha say there is a tendency for producers to underestimate crude protein and overestimate energy.

“The cheapest money you will ever spend in a beef cattle operation is a forage test, guaranteed,” Saha says.

He explains a great illustration of this happened recently during the UGA Master Cattlemen’s Program. As part of the program, a free forage test was offered to participants along with a survey to estimate what producers thought the quality of the hay was prior to testing. This survey showed 83% of producers were underestimating the protein of their hay compared to the actual. This would result in purchasing a protein supplement when not needed.

For energy, 50% overestimated the level, resulting in depriving needed energy during late gestation and early lactation. In addition to the previously discussed fetal programming issues, this could also cause delayed breeding.

Figure 2: Actual example of over estimating energy.

(UGA)

An example of overestimation of energy is illustrated the example above. The overestimation could likely result in breeding being delayed 42 days. The resulting loss in weaning weight could easily reach 80 lb., leading to an approximate $280 decrease in value per calf.

“Through forage testing, the producer would know to feed 4 lb./day of a supplement such as corn gluten feed. Based on a 25-cow herd, this could easily return $6,325 above cost. That is a no-brainer,” Saha explains.

Brood cow nutrition is a crucial part of a beef cattle operation. Between fetal programming and maintaining the proper calving interval, it is imperative for producers to pay close attention to the nutrients available in their forages, and if they meet the requirements of their herd.

2 Veterinarians Share Their Tips for Keeping Calves Healthy

Thu, 08 Jan 2026 14:51:44 GMT

Health issues during calving season are high on the list of nightmares for ranchers. Veterinarians Troy Dutton and Joe Hochhalter from the Steele Vet Clinic in Steele, N.D., share several of their tips and strategies to help ranchers stay ahead of illness and health challenges this calving season.

Prevention is Key

Calves might get an official ID in the spring, but other factors throughout gestation impact the health of that calf before they hit the ground. This starts by focusing on challenges or risks your unique operation may experience throughout the year.

Dutton says: “It’s a lot easier and more rewarding to help people prevent problems than help them work through problems like scours and pneumonia in baby calves.”

Be honest with your veterinarian so you get the most accurate and timely advice.

“If you’re dealing with a specific problem, discussing that issue with your veterinarian before we get to calving season gives us a chance to intervene early,” Hochhalter says.

Year-round nutrition also plays a role in keeping calves healthy.

“We start all the way back prebreeding to make sure nutrition-wise they’re set up properly,” Dutton explains. “Work with a nutritionist to make sure your herd’s energy and protein needs are being met as well as provide mineral year-round.”

Additionally, monitor body condition scores throughout the year.

Hochhalter adds: “Those cows that are in good body condition at the time of calving are more likely to birth a healthier calf, have better quality colostrum for that calf and be in a better condition to breed back.”

Keep in mind the unique needs of your operation.

“Every rancher is different. You really have to work with your local veterinarian to help address those issues that the ranch is having,” Hochhalter says.

Get Them Off to a Good Start

Once calves hit the ground, a good start sets them up for the rest of their lives.

Hochhalter explains: “Calves that have some kind of calfhood disease never do catch up to their herd mates that have been healthy their whole life.”

Colostrum is a key component to this good start.

“Growing up, I was always told that calf needs colostrum within 24 hours. However, recent research shows us calves need colostrum sooner than that,” Dutton says. “Calves need colostrum within 6 to 12 hours of birth to get the most out of the antibodies it provides.”

Adequate colostrum impacts more than just health, too.

“Calves with adequate colostrum have better rate of gain and feed efficiency all the way through to the end,” Dutton says.

Dutton and Hochhalter encourage producers to know the difference between colostrum replacement and colostrum supplement in situations where the dam cannot provide colostrum.

Dutton says: “There are colostrum supplement products and colostrum replacement products. Colostrum replacement products have greater than 150 immunoglobulins.”

Sanitation and Calving Barns

Sanitation and calving areas look different depending on the time of year, herd size and geographical area of the ranch.

Regardless, keeping cattle clean and dry is non-negotiable.
For those using calving barns, know when to change out the bedding.

“In a perfect world, we’d like to see each new pair get fresh bedding, but that’s not realistic,” Hochhalter says. “The next best option is to change that bedding once it becomes damp and spoiled to reduce the exposure of pathogens to calves with naïve immune systems.”

Clean pens between pairs reduces the risk of disease spread along with proper ventilation.

“One overlooked factor that plays a role in the spread of disease is ventilation in calving barns,” Dutton says. “Ventilation issues present a real challenge even in the beef industry — especially for those early calvers.”

Sanitary equipment also can’t be forgotten in the calving frenzy.

Dutton says: “Equipment sanitation is also important — especially if you’re running around giving a bolus to a calf or using needles and syringes.”

For producers not using a barn, be aware of how mud impacts calf health.

“Weather plays a huge role. If those calves are really muddy, it increases the risk for navel infection or scours,” Hochhalter says.

Try to change bedding around shelters and find dry areas for cattle. Spreading cattle out also helps reduce disease transmission.

“We have some clients who sort pairs by age or keep pairs separate from cows left to calve, and we know reducing that calving density reduces the spread of illness,” Dutton explains. “However, this can be challenging depending on labor and resource availability.”

Remember the basics this calving season and don’t forget to ask your veterinarian for help when you need it. You can listen to the full conversation on the Casual Cattle Conversations podcast .

How Important is Colostrum?

Wed, 07 Jan 2026 16:50:41 GMT

A make-or-break moment for the future potential of a calf is within hours of them being born . Receiving colostrum — the first milk produced by a cow after birth that is rich in antibodies, energy, vitamins and minerals that the calf cannot obtain before birth — is essential to a calf’s future.

South Dakota State University Extension beef specialist Julie Walker says the timing of colostrum consumption in calves is critical.

“At birth they should receive at least 5% of the calf’s body weight,” Walker says. “After 24 hours, the calf’s intestine tract cannot absorb the antibodies intact.”

If the calf does not receive colostrum, Walker says you could see an increase in risk of disease, making them more susceptible to pneumonia, sours, septicemia and joint issues.

“Since they lack passive immunity without colostrum, they might be a poor doing calf,” she adds. “This can be seen later in their life. When everything goes right, calves receive colostrum from nursing on the cow.”

North Carolina State University beef Extension veterinarian Tomas Gonzalez agrees that in a normal birth, the calf should be on its feet within about an hour and nursing the cow on its own soon after.

“Most beef operations rely on this natural nursing, and when the cow has good maternal behavior and weather conditions are favorable, this approach works well,” Gonzalez says. “Still, having a colostrum management plan available as a backup is critical, as not every calf nurses adequately in the first few hours.”

Colostrum Replacement

Having a replacement plan prepared before calving helps producers manage abnormal situations quickly and effectively. Walker and Gonzales agree there are three options to replace colostrum: milking the dam to collect the colostrum, colostrum from another cow or commercially available products.

“If a newborn calf is not nursing, the first step is to milk the dam and feed her colostrum to the calf using a bottle or an esophageal feeder [after proper training by your veterinarian],” Gonzales explains. “If this is not possible, colostrum [not milk] from another healthy, properly vaccinated cow in the herd can be used.”

Walker adds that you want to only obtain colostrum from healthy cows, preferably in their third lactation.

“If you have the opportunity to pick the cow you would collect colostrum from, ideally it would be a cow in its third lactation or greater, since this would provide higher-quality colostrum than two-year-old cows,” she says. “It can be difficult to get colostrum from beef cows, so some producers may work with a local dairy producer to get colostrum and freeze it until needed.”

The third option when neither of the above is available is a colostrum replacer. Gonzales says to be sure it is a true replacer, at least 100 g IgG per dose, and not just a supplement. While colostrum replacer is not the same as colostrum from a cow, it can sometimes be the only option and is better than not receiving anything.

“When it is needed, it provides immunoglobulin that helps with passive immunity coverage,” Walker says. “Follow the label when preparing the replacer and get it into the calf as soon as possible. Our best substitute is milking another cow in the same herd, but if you can’t get that, a colostrum milk replacer or substitute is certainly the way to go, and there’s producers that will just keep that on hand just in case they need that.”

Tips For Calving Season

It is often hard to tell if a calf has nursed or not, especially on an older cow. Gonzales recommends watching every newborn long enough to see it stand and actually latch onto the teat. If it hasn’t been nursed within 1 to 2 hours of birth, then step in.

Another tip he shares is to record problem calvings and assisted colostrum feedings. This helps make cull decisions down the road and better prepare for future calving.

Have a colostrum plan before the first calf is born and keep a basic calving kit ready to be prepared before a problem occurs. He says to be sure to identify your high-risk calves, use records to spot problems and work with your veterinarian closely.

“During the calving season , remember that colostrum management is critical to giving calves a strong start and preventing avoidable losses,” Gonzales says.

As Screwworm Inches Closer, When Could the U.S. Reopen the Southern Border to Cattle Imports?

Tue, 06 Jan 2026 20:49:11 GMT

A newly confirmed case of New World screwworm (NWS) in northern Mexico is renewing concern among U.S. cattle producers and policymakers, as the parasitic fly continues to inch closer to the U.S.-Mexico border.

As reported by Drovers, on Dec. 27, Mexico’s National Service of Agro-Alimentary Health, Safety, and Quality (SENASICA) reported a case of NWS in a 6-day-old calf with an umbilical lesion in the municipality of Llera, located in the state of Tamaulipas. The location is approximately 197 miles south of the U.S.-Mexico border, and a reminder that NWS is still a high threat to the U.S.

Critical Timing with Calving Season Approaching

NWS, which was eradicated from the U.S. in the 1960s through an extensive sterile fly program, poses a serious threat to livestock. The larvae infest open wounds, feeding on living tissue and often leading to severe injury or death if untreated. Calving season is considered a particularly vulnerable period due to natural points of entry such as navels and birthing injuries.

Seth Meyer, director of the Food and Agricultural Policy Research Institute (FAPRI) and former chief economist for USDA, says the new case raises a tremendous amount of concern as USDA remains vigilant on keeping NWS out of the U.S. But Meyer says the growing proximity of NWS complicates already difficult decisions for cattle producers at calving season , which is a critical time of the year.

“There are concerns not just from a consumer standpoint, but also about whether southern producers are willing to retain heifers during calving season if there’s a risk of fly exposure,” he says. “Calving is a point of access for these animals, and that risk matters.”

Those decisions could have longer-term implications for herd expansion and cattle supplies, Meyer notes. If producers decide the risk is too great and opt against retaining replacement heifers, it could tighten supplies further down the road.

“That’s the last thing you want,” Meyer says. “You don’t want people giving up on retaining heifers and turning away from herd rebuilding.”

The Possibility of Reopening the Southern Border

The U.S. most recently closed its southern border to Mexican cattle imports in May of 2025 due to the rapid spread of NWS in Mexico. There were additional closures and reopenings in July 2025 as the situation evolved ultimately halting trade again to protect U.S. livestock.

Here’s a timeline so far:

November 2024: NWS was first detected in southern Mexico, leading to initial border closures and trade disruptions.
Feb. 1, 2025: A temporary ban was lifted after agreements for inspections.
May 11, 2025: U.S Secretary of Agriculture Brooke Rollins ordered an immediate suspension of imports due to NWS spreading closer to the border.
July 2025: A phased reopening began but was halted again after new NWS cases were found farther north, leading to another immediate closure of southern ports to protect American livestock.

Considering the cattle just south of the border are being vigilantly monitored and inspected, the bigger threat of NWS crossing the Southern border could be through wildlife . Still, as NWS gets closer, USDA is keeping the border closed and remaining cautious.

When could the U.S. reopen the border? That’s exactly what Farm Journal asked economists in the latest Ag Economists’ Monthly Monitor and the responses were extremely mixed. It’s important to note the survey was sent out prior to the most recent detection of NWS.

33% of economists say USDA could reopen the border in February 2026
25% say it could happen April through June
17% think the border could reopen July through September
And 17% were unsure.

For policymakers, the situation adds another layer of complexity as they balance animal health, trade and producer confidence. While officials stress that there is no immediate threat to the U.S. herd, the latest detection underscores the importance of surveillance, rapid response and continued cooperation between U.S. and Mexican animal health authorities.

As Meyer puts it: “There are a lot of balls in the air right now,” and preventing NWS from crossing the border remains a critical priority for the livestock industry on both sides.

Follow Farm Journal’s extensive coverage of the ongoing NWS situation.

Cow Herd Scorecard: Evaluating Performance Post Calving

Wed, 14 May 2025 21:59:31 GMT

Tracking performance and evaluating herd success is a year-round process. Similar to tracking athletes, consider developing a scorecard to monitor your herd.

Understanding how your herd is performing throughout the year is important when considering management, nutrition and culling decisions.

For spring-calving herds, now is the time to evaluate and review calving success and failures.

“This is a good time of year to review your records, and if the numbers aren’t where you want them to be, you can make management adjustments under the guidance of your veterinarian, nutritionist or another adviser,” says Jason Warner, Kansas State University cow-calf Extension specialist. Warner was a guest during a recent K-State Beef Cattle Institute Podcast .

A herd’s postcalving scorecard should include:

pregnancy percentages
death loss
calving ease/calving complications – prolapse or retained placenta
udder scores
body condition score
mothering ability and disposition
calving interval

Two areas Warner tells producers to focus on are the number of live calves born compared to the number of cows exposed to bulls at the start of the breeding season; and the number of cows that became pregnant early in the breeding season.

A top priority for Bob Larson, K-State veterinarian, is to have calves born early in the calving season.

“The goal is to have 65% of the calves born in the first 21 days, and 85% to 90% of the calves born within the first 42 days of the season,” Larson say. “If that happens, I know that the cows were in good body condition at the start of the breeding season and the bulls were fertile.”

Larson references USDA’s National Animal Health Monitoring Service (NAHMS) for national averages on abortion and calf death loss.

“The national average is between 1% to 2% for calf death loss and that will vary from year to year within the same operation,” Larson said. “If the producer is calving out a high percentage of heifers, that can influence the calf death loss percentage.”

Scorecard Prep
Ron Lemenager, Purdue professor and beef Extension specialist, suggests producers consider creating a spreadsheet to calculate important percentages, prior to filling out their postcalving scorecard.

He encourages producers record and monitor these numbers each calving season:

Number of cows exposed
Number of cows pregnant
Number of cows pregnant / Number of cows exposed = % Pregnant
Number of pregnant cows kept to calve
Number of cows that calved
Number of cows that calved / Number of pregnant cows kept to calve = % Calving
Number of Live Calves
Number of Live Calves /Number of cows that calved = % live calves born
Number of live calves after one month
Number of difficult or assisted birth (dystocia, prolapse)
Number of cows with bad udders
Number of cows BCS 5 or 6
Number of cows with poor disposition and poor mothering ability
Number of cows that calved in the first 21 days
Number of cows that calved in the second 21 days
Number of cows that calved in the third 21 days
Number of cows that calved after 63 days

Lemenager explains using the spreadsheet to calculate the percentages can help producers identify specific problem areas in their calving and breeding processes and allows them to troubleshoot their herd’s breeding performance.

“Tracking herd performance allows producers to zero in on their problems and determine what issues are really facing the herd,” he summarizes.

Understanding the challenges facing a cow herd can help producers determine what nutrition or management strategies can be used to improve their herd’s postcalving scorecard in future years.

Calving Tips: Dealing with Protective Moms

Tue, 08 Apr 2025 13:24:28 GMT

As spring calving season continues, producers continue to monitor and assist when needed as their next calf crop hits the ground. Dealing with protective moms can be a challenging situation, two industry leaders and a producer share their tips on how to prevent and cope with the situation when faced with an unruly cow.

The first 24 hours is a key time in the newborn’s life. Ron Lemenager, Purdue beef specialist, says calves older than 24 hours are typically hard to catch, so if you plan to process the newborn, it should be done as soon as possible after birth.

“Outside of colostrum, I don’t often talk about some of the other chores that might need done in that time period,” says AJ Tarpoff, Kansas State University Extension veterinarian. “Simply because it’s different for every operation.”

Work as a team: It’s hard to know if you are in danger without someone watching your back. One person can entertain the cow, while the other can tag or accomplish what is needed.”

Depending on your management program, producers may choose to perform some of these tasks in the first 24 hours: tagging, castrating, dehorning, taking birth weights, giving selenium injections or recording calf information in a calving book.

It might be necessary to use nutritional supplements/injectables depending on the operation and cow status. Tarpoff encourages producers to discuss proper products and protocols to use at calving with your veterinarian prior to the first calf hitting the ground.

Commercial cattle producer Tyler Tobald, JTAC Farms, Glasco, Kan., shares his process for newborn calves.

“In the first 24 hours after calving, I will usually put ear tags into the calf,” he says. “If the calf is a bull, I band it. Then, I give the calf some oral vitamin A, D, E, B12 gel while I use a leg band to get its weight. We rotate our calving areas in different parts of the pasture and attached field. After I’m all done tagging, I enter the calf into CattleMax and record any other notes about the cow and calf that I deem important to know for the future.”

Obviously, cow behavior can be a factor when processing a newborn. Just like the video published with this story, sometimes a protective mom decides she is not happy with a producer touching her calf. Tobald says his goal is to keep a cow’s stress levels down as much as possible.

“I check the pair out on a side-by-side,” he explains. “When I roll up, I try to be as quiet as possible and not just zoom up on them. After that, I try to be as quiet as I can. I don’t hoop, holler, talk or anything that will add stimulation to an already stressful situation. I also always keep the cow in front of me as best as possible. The last thing I want is for an amped up 1,300-lb. animal behind me where it can sneak attack me.”

Tobald says his philosophy on dealing with cows, even the over-protective ones, is using the most important of the Roadhouse Rules: Be nice until it’s time to not be nice.

“Thankfully this is a very rare occurrence,” he says. “I make notes of any cow that is over-protective, so I know what I’m dealing with when I approach them in the future. But if the cow gets more aggressive the next year, then the calf doesn’t even get tags and gets loaded into a trailer with the cow and they go to the sale. Life is too short for crazy or mean cows.”

Lemenager explains that right after a cow gives birth, her hormones are raging.

“That’s part of the process that helps her bond to that calf,” he says. “She also needs to stimulate the calf, so it gets up and nurses. If any part of that natural process is interrupted, the cow can become very aggressive.”

Tarpoff shares these tips for dealing with overly protective mother cows.

Have some type of physical separation from mom. This might be a fence, panel, gate, truck, side-by-side. “The only truly safe location is to have a physical barrier between you and the cow while working with the calf”
Work as a team. “It’s hard to know if you are in danger without someone watching your back. One person can entertain the cow, while the other can tag or accomplish what is needed.”
Be efficient and thoughtful with the calf manipulation. “It only takes one painful bellow from the calf to set the cow off. Save potentially painful manipulations until last (ear tags or castration).
Be smart. “Don’t assume cows are faking a threat. When in doubt, always take the safe approach. The chore can always be completed later if the cow is on the fight. Keep records and plan to handle the situation when she calms down.”
Stay safe. “If we get injured, we put stress on the rest of our family and operation.”

Different strategies can help keep the producer and calf safe during newborn processing.

“Some ranchers use a cage on the side of their ATV,” Lemenager explains. “This allows for bringing that calf into the cage while handling it. Another option is to have two people working with the calf. One to care for the calf and the second to keep the cow away.”

If you are going to try to move a calf to another location, an option is a polypropylene plastic sled or a calf carrier on an ATV (calf sling). Lemenager says a cow will typically follow because she can smell and see her calf.

“Ideally, when working with a cow-calf pair, I try to keep the calf between me and the cow,” Lemenager says. “Most, but not all cows, are calmer and less aggressive when they can see and smell their calf.”

Lemenager summarizes a key to improving your cow herd behavior is to consistently use low-stress handling to help desensitize cattle to the presence of people.

Avoiding The Calfcicle: Calving in Winter Weather

Mon, 17 Feb 2025 18:33:37 GMT

Calving season is just around the corner or has already arrived for many. Preparing in advance, particularly for those facing inclement weather , will position producers to successfully address the needs of calves and avoid “calfcicles” in frigid temperatures.

Even before delivery, evaluating calving locations and facilities is a good place to start. Areas should be clean and dry. Consider providing shelters for animals to escape the weather. However, remember that as animals congregate, there can be an increase in disease contamination and transmission. Excellent on-site facilities or the ability to transport to a veterinary clinic is essential when addressing calving problems.

Remember to discuss your calving plan with your veterinarian. Build a relationship with your veterinarian well before a 2 am emergency calving call. Due to high demand, many veterinary practices will only accept emergencies from existing clients. Your veterinarian can work with you and your team to develop protocols for handling calving issues, especially during the cold.

At calving, heifers that labor in Stage 2 of parturition for longer than an hour, and cows that labor longer than 30 minutes, should be examined immediately. Be certain that calving equipment is clean, functional, and readily accessible. Your veterinarian can also help you develop essentials for a calving kit with critical items and medications.

Following delivery, the goal is to see the calf up and nursing as soon as possible. Delays in a calf receiving colostrum have both short and long-term impact on the immune system and in many cases set calves up for failure. Ideally, a calf should receive colostrum within the first two hours of life. Administering colostrum to calves without a suckle reflex using an esophageal feeder should be done with extreme caution due to the increased risk of aspiration pneumonia. Milking the dam or maintaining a supply of frozen colostrum are the best options for colostrum replacement.

Although recent arrivals are potentially most susceptible, even older, sick calves fail to tolerate extreme temperatures. Calves should be evaluated at least daily for signs of illness. The best way to monitor a calf’s temperature is with a rectal thermometer. Inexpensive digital thermometers work well and make it easy to evaluate progress when warming the calf is needed. If a calf’s temperature falls below 100 degrees F, gradually raise that temperature. Bring the calf indoors and out of the elements if needed. When used appropriately, warm water baths, blankets, and warming boxes are all options to rewarm a calf.

Be careful not to damage the skin of the animal by either rubbing too vigorously or placing the animal close to heaters. Additionally, if the calf is brand new, do not wash off the odor of amniotic fluid. This helps prevent rejection by the dam. Treatment of “calfcicles” often goes well beyond just warming.

Evaluating and correcting the underlying cause of a calf’s low temperature is key, especially if there is an infectious agent, such as those that can cause diarrhea, contributing to the condition. Oral or intravenous fluids, as advised by a veterinarian, can assist in warming and addressing internal fluid deficits. The metabolic state, including glucose levels and acid-base balances, should be considered. Medications to treat symptoms and nutrition for calves should not be overlooked. Intensive care of some calves and veterinary hospitalization may be needed depending on the value of the animal.

Early detection and interventions of frozen “calfcicles,” along with working with your veterinarian to develop protocols before calving season, can reduce stress and lead to more successful outcomes during calving season.
