There is a paucity of information from western Canadian beef cow-calf producers about how they control gastrointestinal nematodes. The objectives of this study were to describe cow-calf producers' management practices related to control of gastrointestinal nematodes including pasture management and use of parasite control products. A questionnaire was distributed to 105 producers in May 2015. Responses from 97 producers revealed the almost uniform dependence on the use of a pour-on macrocyclic lactone parasite control product in the fall as part of a routine farm management program. Control of external parasites was the primary reason for treatment, while none of the producers chose to treat specifically to manage internal parasites. The predominant management practices identified through this study increase the risk of development of anthelmintic resistance. The results also highlight the need to raise awareness of the importance of an evidence-based gastrointestinal nematode control program in beef cow-calf herds.
关于加拿大西部肉牛繁殖母牛养殖户如何控制胃肠道线虫，可获取的信息很少。本研究的目的是描述繁殖母牛养殖户与胃肠道线虫控制相关的管理措施，包括牧场管理和寄生虫控制产品的使用。2015年5月，向105位养殖户发放了调查问卷。97位养殖户的回复显示，作为常规农场管理计划的一部分，秋季几乎一致依赖使用浇泼型大环内酯类寄生虫控制产品。控制体外寄生虫是进行治疗的主要原因，而没有养殖户选择专门针对体内寄生虫进行治疗。通过本研究确定的主要管理措施增加了抗驱虫药产生的风险。研究结果还凸显出有必要提高人们对肉牛繁殖母牛群中基于证据的胃肠道线虫控制计划重要性的认识。
