Incidence of Persistent Bovine Viral Diarrheal Infection in Arkansas Stocker Calves

摘要

A study was conducted to determine the incidence of bovine viral diarrhea virus (BVD) persistent infections based on tissue samples obtained from stacker cattle originating from Arkansas sale barns. Tissue samples were collected from 221 stacker calves from the Livestock & Forestry Branch Station at Batesville, Ark., and 279 stackers from the Beef Cattle Research Facility at Savoy, Ark. The samples were shipped to the Oklahoma Animal Disease Diagnostic Laboratory for analysis. An immunohistochemistry test was performed on each sample to determine if the calf was persistently infected with bovine viral diarrhea virus. The incidence of the disease in the cattle that were tested was 0.8% (4 of 500).
