Know the signs of fog fever

Vet Advice with Dr. Ron Clarke

By

Public trust is a ticket forward for the food industry

Vet Advice with Dr. Ron Clarke

By
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.

Understanding the new drug regulations

Vet Advice with Dr. Ron Clarke

By
New regulations governing the purchase and use of antimicrobials (antibiotics) necessitate time spent between veterinarians and producers. Everyone has an opinion. Phrases like “prudent use,” “veterinary-client-patient-relationships,” “veterinary-pharmaceutical stewardship,” “veterinary oversight,” and “documented evidence” pepper the pages of government, academic and veterinary documents issued around antimicrobial use. There is a new vocabulary to be learned, the […] Read more

Preg-checking scorecard for cow-calf producers

Vet Advice with Dr. Ron Clarke

By
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
