BVD Vaccination Trial

Abstract

Clinical cases of BVD are either enteric or reproductive problems. The enteric form causes economic loss in animals that die of acute or chronic diarrhea. The reproductive form may contribute to losses by causing abortions, repeat breeders or the birth of malformed calves usually following a BVD infection in non-immune heifers. The magnitude of the economic losses due to the reproductive form has not been accurately determined and this should be done so the cost of the disease can be compared to the cost of control.
