Rabies is a rare zoonotic disease

… and it’s almost always fatal to animals

We don’t hear about rabies being mentioned very often but when we do there is a scary connotation attached to it.

Animal Health: Treatment for the elusive diseases grows closer

We hope within a two-year window we will have candidates ready to test out in the field.” These encouraging words come from Dr. Andrew Potter, CEO at the […] Read more


Precondition calves regardless of weaning time

The well-prepared, preconditioned calf rewards the producer, the buyer and, most importantly, the calf

Now is the time to start preparing calves for marketing with a sound preconditioning program developed in concert with your veterinarian.
