Arnold Nagely, DVM, and Ray Shultz, DVM, are more likely to be associated with their veterinary supply business, Valley Vet Supply, than as practitioners. Both doctors spent years in veterinary practice before expanding their retail clinic business into the OTC catalog offerings known today.
Nagely and Shultz discuss summer, or pasture pneumonia ,which infects calves as typical postweaning bovine respiratory disease, or BRD. Summer also brings increased fly numbers. With them comes increased risks for pinkeye caused when flies transfer Moraxella sp. bacteria from one calf to another.
Flies also negatively affect rate of gain. They draw blood 20 to 40 times/fly/day generally disrupting cows’ ability to relax. <Link>
