Understanding the new drug regulations

Vet Advice with Dr. Ron Clarke

New regulations governing the purchase and use of antimicrobials (antibiotics) necessitate time spent between veterinarians and producers. Everyone has an opinion.

If you suspect a calf with BRSV, getting it out into a fresh, cool area is critical.

BRSV (bovine respiratory syncytial virus) is a deadly viral cause of pneumonia

Health: Know the signs and what actions you should take if you suspect the virus
