Researchers detected infectious H5N1 virus in milking parlor air and wastewater systems while also identifying possible subclinical infections in cattle.
A newly identified cellular structure inside rumen microbes may be quietly driving a significant share of enteric methane production, potentially providing a more precise target for intervention.
New research shows even low levels of stable flies can trigger cattle bunching and measurable milk losses, making it an early warning sign for on-farm stress.
A novel H5N1 vaccine designed to trigger both respiratory and systemic immunity is showing early success in cattle, offering a potential breakthrough as avian influenza spreads across species.
Over-treating for metritis could be costing the U.S. dairy industry close to $270 million annually.
Crowd gates are often one of the most used tools on a dairy. However, just like any tool, crowd gates can be used incorrectly and can sometimes negatively impact cow comfort and welfare.
Tasia Kendrick explains why bovine leukemia virus often goes unnoticed in dairy herds and how it quietly affects immunity, longevity and profitability.
The affected herd is located in Charlevoix County, located west of Michigan’s Modified Accredited Zone (MAZ), where the disease is known to be present in the state’s white-tailed deer population. The detection follows identification of bovine TB in an adult cow at a USDA Food Safety Inspection Service-inspected processing plant.
As the limitations of manual culturing and visual inspection become more apparent, the industry is shifting toward passive detection — systems that monitor the cow without requiring extra labor hours. But this requires expert interpretation from veterinarians to ensure the data translates into actionable treatment.
Mastitis is a systems problem, not just an infection. Control requires shifting from reactive treatment to proactive management and using data to solve health issues at the source.
The new generic drug has been approved for treatment of bovine respiratory disease and associated pyrexia in beef and non-lactating dairy cattle.
Culling decisions should be just as important as breeding decisions. Here, two experts explain what to consider when replacing cows in a milking herd.
Milk yield, components and udder health metrics can reveal early disease long before clinical signs emerge. Learning to interpret these signals can transform routine milk data into proactive herd health interventions.
A serious game from the University of Wisconsin-Madison is helping veterinarians and dairy teams improve animal welfare, safety and efficiency — one virtual cow at a time.
Modern herds generate more information than ever. Veterinarians are key to interpreting it and guiding data-driven management decisions.
Even the best vaccine can fail if mismanaged. Dr. Jon Townsend outlines good handling practices to protect your investment and your cattle.
Cull cow marketing is rarely an all-or-nothing decision. The nuances of each operation should be discussed when deciding to remove an animal from the herd.
New data from four calf ranches highlight the dominance of respiratory disease and the year-round consistency of health challenges in beef-dairy cross calves.
National Veterinarian Technician Week is upon us. Take this opportunity to consider the impact a CVT could have on your practice.
Analysis of almost 1,500 liver samples from beef and dairy cattle reveals persistent trace mineral deficiencies affecting herd health.
Generics can save money without sacrificing safety or efficacy, but veterinarians and producers must consider how each product performs under their unique herd conditions.
New World screwworm was essentially eradicated in the U.S. in 1966, but the persistent pest has rebounded through considerable geography in the past year, prompting the closure of the U.S./Mexico border to cattle in recent months.
Economics suggest producers will keep cull rates low.
Training deficiencies consistently rank among the top program corrective actions within industry evaluations. That’s why a team of veterinarians created DairyKind: an online platform that delivers on-demand training accessible in the native language of the employee.
Focusing on the fundamentals of feedbunk practices is often all it takes to support healthier, more productive cows.
MEPS technology at scale is a crucial step toward delivering a commercial solution by 2026.
Giving heifers some practice time with an automated milking system before calving could help them adapt faster and boost milk production during the first few weeks of lactation.
