Public trust is a ticket forward for the food industry

Vet Advice with Dr. Ron Clarke

The economic, social and political environment around agriculture has changed. The public, particularly consumers, have influenced the landscape of food production in ways never before recognized. The closer an industry sector’s shift is toward the supermarket meat counter and grocery shelves, the more advanced is the call toward public reckoning about matters involving the food […] Read more



Vet Advice: New regs to preserve old and new drugs

I’m often asked why even older antimicrobials are still considered medically important to human medicine. The premise, right or wrong, is to preserve antibiotic effectiveness by reducing the risk of antimicrobial resistance attributed to wholesale use in animal agriculture. While debate still rages over the impact new legislation will have on preserving antimicrobial effectiveness in […] Read more


Cold and abomasal impaction

Vet Advice with Dr. Ron Clarke

Beef cattle on the Canadian Prairies are subject to considerable environmental stress during winter. Starting with the early days of ranching and arrival of U.S. cattle onto the eastern slopes of the Rockies through the mid-1800s, survival of the beef cow meant adaptation to prolonged cold temperatures.

Sweet clover poisoning — an old problem persists

Vet Advice with Dr. Ron Clarke

Mouldy sweet clover poisoning in cattle is caused by the ingestion of sweet clover hay or ensilage containing dicoumarol.

Preg-checking scorecard for cow-calf producers

Vet Advice with Dr. Ron Clarke

Pregnancy checking remains one of the most underutilized management tools in the cow-calf business. Overlooking the chance to gather herd information as cows come off pasture in the fall is a missed opportunity for the cow-calf producer. A trip through the chute in fall should be much more than determining which cows to keep and […] Read more

Though only two varieties exist, they are responsible for a wide range of diseases

By scientific estimate, ticks have been around for 100 million years. They represent the most famous blood-sucking arachnids, (eight-legged organisms).
