In outbreaks of disease with the bovine virus diarrhoea virus (BVD virus), the economic loss to fourteen dairy farms was determined on the basis of the amount of loss per dairy cow. The patients included cases of abortion, stillbirths, delivery of calves showing lesions, lesions of the feet, mucosal disease and animals persistently infected with BVD virus. BVD virus was isolated from several cases of disease on all farms. It was not possible, however, directly to examine all individuals for the presence of the virus. The amount of loss caused by BVD virus was Dfl. 136,- per average dairy cow. The amount varied between individual farms from Dfl. 42,- to Dfl. 285,- per dairy cow.
在牛病毒性腹泻病毒（BVD病毒）引发的疾病暴发中，根据每头奶牛的损失量确定了14个奶牛场的经济损失。患病情况包括流产、死产、产出有病变的犊牛、足部病变、黏膜病以及持续感染BVD病毒的动物。在所有农场的多起病例中均分离出了BVD病毒。然而，无法直接检测所有个体是否感染该病毒。BVD病毒造成的损失为每头平均奶牛136荷兰盾。各农场之间每头奶牛的损失量有所不同，从42荷兰盾到285荷兰盾不等。
