Control of gastrointestinal nematodes (GIN) can have both economic and health benefits for cattle operations in the southern United States. In the past several decades, GIN control has relied almost exclusively on the use of anthelmintics. With the increase in anthelmintic resistance new strategies must be developed. Anthelmintic use should be minimized by integrating grazing management and a good herd health program into GIN control programs. This takes knowledge of GIN biology and epidemiology in the region (climate and weather) combined with specific information from the ranch.
在美国南部，控制胃肠道线虫（GIN）对牛场具有经济和健康双重益处。在过去几十年中，GIN 的防治几乎完全依赖于驱虫剂的使用。随着驱虫剂耐药性的增加，必须开发新的策略。通过将放牧管理和良好的牛群健康计划纳入 GIN 防治计划，可以最大限度地减少驱虫剂的使用。这需要了解该地区（气候和天气）的 GIN 生物学和流行病学知识，并结合牧场的具体信息。
