The Purdue Veterinary Medicine (PVM) Extension Service advances the delivery of practical applications of research from Purdue University and around the world to the citizens of Indiana that own production agriculture animals. Simply put, PVM veterinarians involved in Extension will strive to help the farmers of Indiana to produce healthy and productive agricultural animals in a sustainable fashion.
If a farm visit is scheduled, your local veterinarian and other professionals of your choice will be invited to participate.
In cases of emergency, please contact the Animal Disease Diagnostic Laboratory at 765-494-7440.
