Abstract
Gouge dehorning was evaluated as a mode of transmitting bovine leukemia virus in Holstein calves at a commercial dairy. Significantly (p less than 0.05) more calves dehorned by the gouge method developed antibodies to bovine leukemia virus, as measured by agar-gel immunodiffusion, three months after dehorning, than calves not dehorned. The field use of a blood-contaminated dehorning device resulted in transmission of bovine leukemia virus.
摘要
在一家商业奶牛场，对凿除法去角作为传播牛白血病病毒的一种方式在荷斯坦犊牛中进行了评估。通过琼脂凝胶免疫扩散法检测发现，采用凿除法去角的犊牛在去角三个月后产生牛白血病病毒抗体的数量显著（p小于0.05）多于未去角的犊牛。使用受血液污染的去角器械进行现场操作导致了牛白血病病毒的传播。
