Therefore, when the calf ’s immune system begins to develop during gestation, it does not recognize

BVD virus is closely related to hog cholera virus and ovine border disease virus, all belonging to the genus Pestivirus. Cattle that are acutely or persistently infected with BVD virus shed the virus in nasal and oral secretions, urine and feces. The virus gains entrance through mucosal membranes and
