Dairy Cattle
As beef-on-dairy economics and transition health reshape dairy management, Dr. Stephen LeBlanc says we should focus on preventing involuntary culling and optimizing productive lifespan rather than simply keeping cows in the herd longer.
The first days after milking stops may influence inflammation, metabolism and performance long before the next calving.
Higher dietary starch reduced methane emissions, but individual cows remained consistently high or low emitters, suggesting biology may play a larger role than previously thought.
Routine milk spectra could help identify dairy cows with greater heat resilience while revealing the biology behind how cattle cope with heat stress.
Research and field experience have answered many of the biggest questions surrounding HPAI while reshaping how veterinarians diagnose, monitor and manage the disease.
As the New York State Fair pauses its iconic live birthing center for 2026, the dairy industry navigates a complex shift in advocacy, balancing strict biosecurity with a new era of digital education.
As temperatures creep their way higher, consider these strategies to help keep calves cool and healthy during the heat of the summer.
Researchers have found a sensor-based fresh cow monitoring program identified more health disorders, increased treatment rates, reduced herd exits and generated better economic outcomes than visual observation alone.
New research from the University of Wisconsin-Madison is investigating whether ultrasound could provide veterinarians with a practical way to monitor mammary involution and identify cows struggling to dry off.
Learn which products are conditionally approved and why a strong veterinarian-client-patient relationship is the only way to manage this devastating pest.
Weak udder support and poor teat placement can create chronic management and mastitis challenges.
As fed cattle weights hit historic highs, a surplus of fat trim is creating an unprecedented need for lean blending beef, pushing cull cow values to new records.
Researchers detected infectious H5N1 virus in milking parlor air and wastewater systems while also identifying possible subclinical infections in cattle.
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.
Over-treating for metritis could be costing the U.S. dairy industry close to $270 million annually.
AI is the newest hired hand on the dairy, moving beyond simple fixes to protect farmer intuition through data-driven precision, better cow comfort, and a sustainable legacy for the next generation.
As the picket lines disappear, the focus returns to the production floor, ensuring the milk supplied by hundreds of upper Midwest farm families continues to reach the market without further delay.
Driven by a 211,000-cow expansion and rising efficiency, a 3% production surge is redrawing the U.S. dairy map and shifting the industry’s center of gravity toward the High Plains.
Even after losing a major export market, the U.S. bovine genetics industry bounced back in 2025.
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.
