Abscessed livers with A+ scores such as this one are condemned.

Cutting time on tylosin

Researchers looked at whether feeding tylosin for a shorter period affects antimicrobial resistance, along with liver abscesses, health and growth of feedlot cattle

Liver abscesses in cattle have been extensively studied for the last 70 years. Yet condemned or discounted livers due to abscesses still cost the Canadian beef industry over $60 million per year. Tylosin, a member of the macrolide family of antimicrobials, is widely used in beef cattle and is administered through the diet to reduce […] Read more

It’s important to keep in mind that animals don’t have to be completely parasite-free to be healthy and productive.

Managing resistance to internal parasites in cattle

Producers need to tailor parasite control to align with their herds and management systems

Managing internal parasite resistance starts with asking the right questions and understanding the principles of antiparasitic resistance and the range of control products. From there, a producer needs to develop a deworming strategy and pin it to the spring and summer grazing calendar. A veterinarian can help. Antiparasitic resistance is typically defined as the genetic […] Read more


New vaccine will stop the spread of bovine TB

Scientists at the University of Surrey have developed a novel vaccine and complementary skin test to protect cattle against bovine tuberculosis (bovine TB). Publishing their findings in the journal Scientific Reports, researchers reveal they have for the first time created a vaccine that is compatible with a synthetic form of the tuberculin skin test (PPD), a […] Read more

A Styrofoam cooler with heat or cold packs is a simple piece of equipment that keeps vaccine at the right temperature.

Keep syringes and needles clean and working during vaccination

Make sure you protect your vaccine’s effectiveness with a few practical steps

Getting the most out of a vaccine starts with the syringes and needles. Dr. Cody Creelman, a bovine veterinarian in southern Alberta, recently held a free webinar on ways to make cattle vaccines more effective. Part of his webinar covered how to keep needles and syringes clean and working well. Creelman recommends checking and replacing […] Read more

Canadian Food Inspection Agency seeks proposals for vaccine matching

Research: News Roundup from the September 30, 2019 issue of Canadian Cattlemen

The Canadian Food Inspection Agency (CFIA) seeks proposals from small businesses on developing a computer model that predicts which vaccine strain would best control foot-and-mouth disease outbreaks in cattle, sheep and swine. Foot-and-mouth is highly contagious, making it a serious threat to the agriculture industry. Viral strains can be stored in vaccine banks, but right […] Read more

Tips for reducing antibiotic use on the ranch

Producers and veterinarians adapt to new rules around livestock antibiotic use

Beef producers used to be able to pick up antibiotics at their favourite farm supply store or local small town co-op, but things changed on December 1, 2018. Since then, Health Canada has mandated that all medically important livestock antibiotics require a veterinary prescription. While producers and veterinarians alike have dealt with some challenges that […] Read more


Wear at the tip of the toe, separation along the white line and an abscess could be signs of toe-tip necrosis.

Toe-tip necrosis in cattle

Don’t overlook this disease when diagnosing lameness in the feedlot

Several things can cause foot soreness in cattle, including foot rot, puncture wounds, sole bruises, abscesses and white line disease. But one of the most serious is infection of the inner parts of the foot, resulting from toe-tip necrosis. Dr. Murray Jelinski of the Western College of Veterinary Medicine at the University of Saskatchewan started […] Read more

For producers wanting to get the most out of a VCPR, consider working with your vet during the slower summer months to build a connection.

Herd health consultations necessary to buy antimicrobials

A veterinarian shares the process of establishing a veterinarian-client-patient relationship through a herd health consultation

While establishing and maintaining a veterinarian-client-patient relationship takes some time and effort, it’s likely simpler than expected, according to one beef cattle veterinarian. Creating a relationship with a veterinarian can provide great value to producers, says *Dr. Cody Creelman, beef cattle veterinarian at Veterinary Agri-Health Services in Airdrie, Alta. Although a large percentage of producers […] Read more


U.S. vaccine supplies are sufficient to control foot-and-mouth in only about four per cent of Iowa’s swine herd or 14 per cent of Texas’s cattle herd.

Foot-and-mouth disease remains a threat to North American livestock

North America needs to prepare better for an outbreak of this economically important disease

Foot-and-mouth disease virus and the disease it causes have been intensively studied for decades. Although we know a great deal about the virus and vaccines used to prevent foot-and-mouth disease, it remains endemic across large parts of Africa, South America, the Middle East and Asia, and is a constant threat to North America. Globally, it […] Read more
