Stop the spread of bovine viral diarrhea virus through early detection and aggressive intervention.
Testing is the ONLY way to identify cattle persistently infected with BVDV
The what, why and how of BVD
Bovine viral diarrhea virus is a member of the genus Pestivirus within the family Flaviviridae. It is a single-stranded enveloped RNA virus that crosses the placenta in pregnant cows that are infected between days 30 and 150 of gestation, causing reproductive losses due to abortions, stillborn calves or calves that die early in life. Calves that survive are immunodeficient to and persistently infected (PI) with the virus.
Persistently infected cattle are the main source of BVDV transmission. PI calves shed large amounts of the virus every day of their life, infecting other animals in the herd. These carrier animals often die of mucosal disease within the first two years of life, however some may live longer.
