Bovine viral diarrhea virus (BVDV) is a potentially serious problem for cow-calf herds and has been implicated as a cause of infertility, abortions, diarrhea, shipping fever (BVD is a huge factor resulting in bovine respiratory disease), immunosuppression (weakening of the immune system which leads to other disease problems), and much more. BVDV infections are classified into three clinical syndromes: acute (transient) infection, fetal infection, and persistent infection.
