In the coast region of the north-west of Germany 269 arbitrary chosen blood samples of 22 flocks of sheep were tested for the existence of BHV-1, BVD and PI-3 antibodies. The livestock of 13 farms with 163 sheep consistent of sheep and bovine, 9 herds with 106 sheep kept sheep only. The results show that BHV-1 antibodies were not present in the sampled sheep. Contrary to this are the results for BVD and PI-3. The blood tests for BVD antibodies were positive in 6.7% of the samples. This result indicates a low prevalence rate of BVD virus in the investigated region. The positive results showed distinct differences in distribution for the two farm types. Out of all BVD antibody positive reactors (n = 18) 83% were located in 7 farms keeping sheep and cattle. The rest of the positive reactors (17%) was found on 2 farms keeping sheep only. For PI-3 the distribution of farms keeping sheep plus cattle vrs. keeping sheep only concerning the antibody positive stocks was 7 positive herds out of 13 vrs. 6 positive herds out of 9. Again within the sheep herds of the two farms types occurred significant differences. Farms with sheep and cattle had 19% to 76% PI-3 antibody positive blood samples and farms with sheep only 1% to 11%.
在德国西北部沿海地区，对22群绵羊随机抽取的269份血样进行了牛疱疹病毒1型（BHV - 1）、牛病毒性腹泻（BVD）和副流感3型（PI - 3）抗体检测。13个农场的家畜中有163只羊，这些农场既有绵羊也有牛；9个畜群中有106只羊，这些畜群只养绵羊。结果显示，所采绵羊血样中不存在BHV - 1抗体。与之相反的是BVD和PI - 3的检测结果。BVD抗体血检中，6.7%的样本呈阳性。这一结果表明在所调查地区BVD病毒的流行率较低。阳性结果在两种农场类型的分布上存在明显差异。在所有BVD抗体阳性反应动物（n = 18）中，83%位于7个既养绵羊又养牛的农场。其余阳性反应动物（17%）出现在2个只养绵羊的农场。对于PI - 3，既养绵羊又养牛的农场与只养绵羊的农场在抗体阳性畜群方面的分布情况是，13个农场中有7个呈阳性，9个农场中有6个呈阳性。同样，在这两种农场类型的绵羊群中也存在显著差异。既养绵羊又养牛的农场中，PI - 3抗体阳性血样占19%至76%，而只养绵羊的农场中为1%至11%。
