It is increasingly difficult to manage and control gastrointestinal nematode parasites in pasture-based ruminant livestock operations because of the high prevalence of anthelmintic resistance. Anthelmintics should be combined with alternative forms of control. Sustainable tools include copper oxide wire particles and condensed tannin-rich plants, which target primarily Haemonchus contortus in small ruminants. Nematophagous fungi reduce larvae on pasture and target nematode larvae in feces of most livestock species. In addition, and perhaps most importantly, genetic selection focuses on parasite resistance. Producers should use as many tools as possible to minimize the need for pharmaceutical interventions and optimize animal production.
由于驱虫药耐药性的高发，牧场养殖反刍动物的胃肠道线虫寄生虫的管理和控制变得愈发困难。驱虫药应与其他控制方法相结合。可持续的工具包括氧化铜线颗粒和富含单宁的植物，主要针对小反刍动物中的捻转血矛线虫。食线虫真菌减少牧场上的幼虫，并针对大多数牲畜粪便中的线虫幼虫。此外，也许最重要的是，基因选择侧重于寄生虫抗性。生产者应尽可能使用多种工具，以最大程度地减少对药物干预的需求并优化动物生产。
