Technical Abstract: The reduction in profit margins that accompany bovine viral diarrhea virus (BVDV) infections in dairy herds stem from: 1. Direct reduction in milk yield that occurs when animals are acutely infected with BVDV; 2. Increased secondary infections accompanied by increasing expenditures for veterinary treatment; 3. Increased fetus/calf mortality and calving intervals; and 4. Reduced milk price due to increased somatic cells in milk. The isolated impact of any one of these factors may appear minimal in a given herd. However, cumulatively they have a significant economic impact. So how do you prevent BVDV from nibbling away your bottom line? You need to have a BVDV control plan in place. An effective plan will monitor for the presence of BVDV in a herd, reduce the risk of BVDV from entering or spreading within the herd, and eliminate animals persistently infected with BVDV. To develop a plan to prevent and eliminate BVDV infections in a herd, you need to understand how BVDV enters a herd and how to detect if it is there.
