Prophylactic anthelmintic treatment of ewes about parturition has only a negligible effects on the most important species of helminths when the ewes and their lambs are not grazed on clean pasture. Haemonchus contortus infections were completely prevented in some cases but usually severe infections occurred. As the build-up of these heavy infections in lambs was slightly delayed in comparison with that in the lambs of untreated ewes, treatment about parturition should still be regarded as useful. Treatment of lambs at the time of weaning combined with moving the animals to a clean pasture is a useful though not entirely effective preventive measure. Particularly when the lambs continue to stay on the farm, they have to be moved to clean pasture and/or treated with anthelmintics more frequently.
当母羊及其羔羊不在清洁牧场放牧时，在分娩前后对母羊进行预防性驱虫治疗，对最重要的蠕虫种类的影响微乎其微。在某些情况下，捻转血矛线虫感染可完全预防，但通常会发生严重感染。与未治疗母羊的羔羊相比，这些羔羊体内严重感染的积累稍有延迟，因此分娩前后的治疗仍应被视为有用的。在断奶时对羔羊进行治疗，并将动物转移到清洁牧场，是一种有用但并非完全有效的预防措施。特别是当羔羊继续留在农场时，它们必须更频繁地转移到清洁牧场和/或用驱虫药进行治疗。
