Abstract

Clinical disease associated with Bovine Viral Diarrhea Virus (BVDV) has been well documented in the literature and includes respiratory, enteric, hemorrhagic, and reproductive problems. While sub-clinical presence of BVDV in herds is also acknowledged, its significance and impact on animal health and herd economics are not well understood. The objective of our ongoing study is to understand BVDV transmission and how the virus becomes established at a sub-clinical level in typically managed herds. In the first phase of the project, reported here, we focused on identifying sources and extent of BVDV transmission in dairy herds.
