Activity monitors, new sensor applications and artificial intelligence could help veterinarians identify respiratory disease earlier and make better use of herd data. Dr. Curt Vlietstra sees opportunities ahead, while emphasizing that technology must work in the realities of the farm.
Serum total protein testing is a common tool for evaluating passive transfer in newborn calves. One veterinarian believes a closer look at the albumin fraction could help explain why some calves fall short, even when colostrum management appears to be on track.
USDA’s fifth national feedlot study charts progress in preconditioning and judicious antibiotic use — while sounding the alarm on written biosecurity and Secure Beef Supply readiness.
Nineteen cattle developed a severe, unexplained disease across multiple farms. Investigators found a common thread in their feed, but couldn’t identify what triggered the outbreak.
In the face of a record nationwide shortage of food-animal veterinarians, Zoetis’ new documentary series spotlights front-line solutions from rural Montana — and four steps cow-calf producers can take today.
Five years of diagnostic surveillance reveal age-related and seasonal patterns in bovine coronavirus detection, alongside continued genetic variation.
At least nine horses have been confirmed with the bacterial disease in 2026. Veterinarians should watch for abscesses, reinforce fly control and follow biosecurity precautions.
Researchers found differences in bacterial combinations between mild and severe liver abscesses, adding to investigations into disease progression and potential prevention strategies.
Merck Animal Health has expanded SenseHub® Dairy Youngstock monitoring to bucket-fed, preweaned calves, broadening the types of dairy operations that can use automated behavioral monitoring.
Young pasture-raised heifers developed mild hoof lesions, prompting testing that identified EHD virus.
A 60- to 90-second chute-side scan can add information about pulmonary disease severity, pneumonia type and treatment prognosis.

Before choosing a vaccine, consider the operation, disease risks, available evidence and when cattle will actually need protection.
For Dr. Brad White, investigating bovine heart disease means looking beyond the heart to understand what is happening throughout the animal.
Veterinary toxicologist Dr. Scott Fritz provides a practical framework for investigating cattle deaths and suspected toxic exposures before the samples ever reach the lab.
Dr. Lane Schmitt shares his approach to managing severely damaged uterine prolapses in the field.
Sweden’s mastitis strategy relies on pathogen-based treatment, selective dry cow therapy and narrow-spectrum antibiotics.
A disease once in the center of cattle abortion research has faded from the conversation, but its economic and reproductive impact remain.

How Dr. John Kastelic combines experience and emerging technologies to evaluate bull fertility.
The first days after milking stops may influence inflammation, metabolism and performance long before the next calving.
Earlier pregnancy diagnosis is giving veterinarians more time to identify reproductive problems, adjust breeding strategies and help producers avoid costly surprises.
Infectious bovine keratoconjunctivitis may be more complex than a single bacterial infection, opening new avenues for prevention and vaccine development.
After unexpected pregnancy losses, a Texas herd discovered PI calves carried by purchased replacement cows had become the source of BVD exposure, prompting a change in surveillance protocols.
Dr. Paige Schmidt-Rios explains why bovine respiratory disease remains one of cattle medicine’s most complex challenges — and why better information, not necessarily more treatments, may be the future.
Lessons from Dr. Maxwell Beal, the veterinarian who diagnosed the first case of HPAI in cattle in California in 2024.
Bovine tuberculosis control changes dramatically depending on where the disease survives. Canada’s recent investigations have focused on tracing rare infections through cattle movements, while Michigan’s long-running battle centers on managing the disease in white-tailed deer.
