A breeding soundness evaluation was conducted on 824 Colorado range rams. These rams were determined to be free from epididymitis via testicular palpation. Semen evaluation included microscopic observation for the presence of WBC. Of the 824 rams, 15.5% failed the breeding soundness evaluation on the basis of the semen evaluation: 10.6% had WBC in the semen and 4.9% had poor sperm morphology. The prevalence of Brucella ovis isolation varied from 0% to 16.2% within flocks. The prevalence of subclinical B ovis infection was 10% in the control flocks. Brucella ovis was isolated from 71.9% of the rams that had WBC in their semen. From this study, it appeared that palpation and vaccination may be inadequate for control of ram epididymitis.
对824只科罗拉多牧场公羊进行了繁殖健全性评估。通过睾丸触诊确定这些公羊没有附睾炎。精液评估包括显微镜观察白细胞的存在情况。在这824只公羊中，15.5%基于精液评估未能通过繁殖健全性评估：10.6%的公羊精液中有白细胞，4.9%的公羊精子形态不佳。羊群中绵羊布鲁氏菌分离率在0%至16.2%之间变化。对照羊群中亚临床绵羊布鲁氏菌感染率为10%。从精液中有白细胞的公羊中分离出绵羊布鲁氏菌的比例为71.9%。从这项研究来看，触诊和疫苗接种可能不足以控制公羊附睾炎。
