Abstract

The introduction of new cattle into an established herd raises the possibility that infection or disease may be either introduced or augmented. Herd additions should be free of infection or disease, or at least have rates which do not exceed those of the herd into which they are introduced. It was reported that the addition of several small herds with prevalences of bovine leukosis virus (BLV) antibodies of 15% to 80%, raised the prevalence of BLV infection in the entire herd from 8% to 23%.' We report the impact of combining two herds, one with a prevalence of BLV antibodies over twice that of the other herd.
