Abstract
All arriving heifer calves and some additional bull calves were tested for bovine viral diarrhea virus (BVDV) persistently infected (PI) status when received by the calf ranch to determine incidence of occurrence across individual dairies contributing calves to this calf ranch. After confirmation of positive status, these animals were removed to eliminate potential for infection in subsequent breeding populations. In addition, 40 random positive PI samples were submitted for typing and genetic characterization to create a dendogram for comparison among PI calves and existing vaccination programs.
