Bovine viral diarrhea virus (BVDV) contributes to the pathogenesis of a number of maladies such as bovine respiratory disease (BRD), reproductive wastage amd acute enteritis. The causative role of BVDV in BRD is of greatest concern to the feedlot industry because BRD is by far the greatest cause of morbidity and mortality in US feedlots. Up to 90% of morbidity and 75% of mortality is attirbutable to respiratory tract disease. More cattle are treated or die from BRD than all other conditions combined.
Despite our increased understanding of its pathogenesis, universal use of vaccines, and availability of efficacious antimicrobial drugs, the proportion of placements dying from respiratory disease has increased.
