Crypto is a major culprit in scours in calves.

Developing a better diagnostic for cryptosporidiosis

Research: News Roundup from the March 2019 issue of Canadian Cattlemen

University of Arizona researchers are developing better diagnostic tools for cryptosporidiosis. Cryptosporidiosis, or crypto, is caused by a microscopic parasite. It’s a major culprit in scours in calves. It’s also a zoonotic and can cause serious infections in humans as well as other animals. Because the parasite can spread quickly and cause dangerous infections, early […] Read more

Swelling and yellow pus is visible in the vocal cords.

Dealing with diphtheria in calves

Animal Health: The condition is serious enough that swelling can restrict breathing to the point of suffocation

Diphtheria is an upper respiratory problem in cattle characterized by an infection or inflammation of the vocal folds. It can be serious if swelling restricts the airway and makes breathing difficult. Dr. Steve Hendrick of Coaldale Veterinary Clinic at Coaldale, Alta., sees quite a few cases of diphtheria in cow-calf operations and in feedlots. “It’s […] Read more


NSAIDs should be used for major procedures such as C-sections at the time of delivery or at the beginning of surgery.

Pain medication at calving and in the feedlot

Pain control is simply the right thing to do in some situations

Pain medication may come with adjunct treatment such as antibiotics but sometimes this is unnecessary. When veterinarians prescribe non-steroidal anti-inflammatory drugs (NSAIDs) for pain, they may choose based on label claim, past experience in the field, price per treatment or per 100 lbs., duration of activity, ease of administration, advice of associates or slaughter withdrawal.

Does antibiotic resistance move through the environment?

Research on the Record with Reynold Bergen

Recent columns have talked about antibiotic use in Canadian cow-calf and feedlot operations. Contrary to common misperceptions, antibiotic-resistant bacteria are very unlikely to transfer from cattle to beef, evade food safety interventions in the processing plant, survive cooking, and cause an antibiotic-resistant infection in a person. But can antibiotic-resistant bacteria be transmitted from cattle, through […] Read more

Researchers decode liver fluke behaviour with 3D modelling

Research: News Roundup from the December 2018 issue of Canadian Cattlemen

[UPDATED: Dec. 17, 2018] Thanks to 3D modelling, scientists have a better idea of how a liver fluke infests livestock. Dicrocoelium dendriticum, commonly known as a lancet fluke or lesser liver fluke, can cause liver disease in cattle, sheep and goats. The Merck Veterinary Manual notes that livestock don’t seem to have any immunity to […] Read more


W.A. Ranches’ gift to veterinary medicine and bovine health

The ranch will be home to the University of Calgary’s beef research and extension programs

Students at the University of Calgary’s faculty of veterinary medicine receive hands-on experience at various beef operations. In many ways it’s been a successful approach — after only 10 years, the University of Calgary vet college is ranked among the top 50 vet schools globally. But conducting research at partnering cow-calf operations poses challenges for […] Read more
