河南牛病毒性腹泻-黏膜病流行病学调查

Epidemiological survey of bovine viral diarrhea-mucosal disease in Henan Province

为探讨河南省牛病毒性腹泻病毒的流行情况,用牛病毒性腹泻病毒抗体检测试剂盒(IDEXX)对本省部分地区6个奶牛场、5个肉牛养殖场的181份牛奶样品和395份血清样品进行BVD抗体的检测。结果检出阳性牛奶106份,阳性率最高为93.3%,最低的为5.0%,平均阳性率为58.6%。其中有5个规模化奶牛场牛奶样品阳性率均在75%以上。肉牛血清样品共检出阳性124份,最高阳性率为74.12%,最低5.80%,平均阳性率31.39%。结果表明,该病在所调查地区中奶牛和肉牛均有感染,不同牛场间感染率差异较大,其中规模化奶牛的感染率较高。表明应采取相应的净化措施对该病进行控制。
