在证明牛白血病病毒通过凿除角在犊牛中传播后，在商业荷斯坦牛群中对较年轻的年龄进行了电除角。随后，对牛群的年度检测显示，随着用前一种方法去角的年老牛被用后一种方法去角的年轻牛取代，牛白血病病毒抗体的流行率有所下降。
Following the demonstration that bovine leukosis virus was transmitted in calves by gouge dehorning, electrical dehorning at a younger age was implemented in a commercial Holstein herd. Subsequently, annual testing of the herd revealed a decline in the prevalence of bovine leukosis virus antibodies as older cattle dehorned by the former method were replaced by younger cattle dehorned by the latter method.
