摘要

在一家商业奶牛场，对割角作为一种传播牛白血病病毒的方式进行了评估。用琼脂凝胶免疫扩散法测定，在去角3个月后，采用凿角法去角的犊牛产生牛白血病病毒抗体的数量显著高于未去角的犊牛(p < 0.05)。野外使用受血液污染的去角器导致牛白血病病毒的传播。

Natural transmission of bovine leukemia virus in dairy calves by dehorning.

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.
