Assessing Epidemiologic Risk of the Quantity of Bovine Viral Diarrhea Virus found to be Associated with in vivo-derived Bovine Embryos

Bovine viral diarrhea virus (BVDV) has been shown to be associated with single transferable in vivo-derived and in vitro-produced bovine embryos despite washing. However, a thorough risk assessment of the potential for transmission of BVDV via transfer of in vivo-derived embryos has not been undertaken. Hence, the primary objective of this study was to evaluate the potential of BVDV to be transmitted during the transfer of in vivo-derived embryos.
