Bovine trichomoniasis is a venereal disease that causes substantial economic losses to the cattle industry worldwide. It has been endemic in the USA since its discovery in the 1930s. The reasons for this long-lasting endemism are poorly understood. The main objective of this study was to identify herd-level risk factors for trichomoniasis in Wyoming beef cattle. A questionnaire was sent to all Wyoming beef cattle producers. The overall response proportion was 23.4 %. Questionnaires were returned from producers throughout the state in different geographical regions and with various herd sizes. In total, 863 questionnaires were analysed for correlation between the disease endemism and 25 variables. Tritrichomonas foetus infections were found to be significantly (P<0.05) associated with neighbouring a positive herd(s), grazing on public allotments and commingling with other herds. In addition, a delay in fixing broken fences approached statistical significance (P = 0.078). This study provides producers with valuable information and useful suggestions on how to effectively control and reduce the risks of bovine trichomoniasis.
牛滴虫病是一种性病，给世界范围内的养牛业造成了巨大的经济损失。自 20 世纪 30 年代发现以来，它一直在美国流行。这种长期流行的原因还不太清楚。本研究的主要目的是确定怀俄明州肉牛群感染滴虫病的风险因素。向所有怀俄明州肉牛养殖户发放了一份调查问卷。总体回复率为 23.4%。调查问卷来自全州不同地理位置和不同规模的养殖户。总共分析了 863 份问卷，以确定疾病流行与 25 个变量之间的相关性。发现感染三滴虫与临近阳性畜群（P<0.05）、在公共分配地放牧以及与其他畜群混群有关。此外，修复破损围栏的延迟也接近统计学意义（P=0.078）。本研究为养殖户提供了有价值的信息和有用的建议，以有效控制和降低牛滴虫病的风险。
