Endoparasitic nematode infection could have negative impacts on performances of sheep and goats. However, supplementary protein and minerals can also affect nematodes. This paper reviews present information on the importance of protein and minerals supplementation as means to control nematode infection in small ruminants. Protein supplementation seems to improve host resilience by diverting metabolizable protein (MP) towards dealing with detrimental effects of the infection and thus improve production and reproductive performances of animal. A large body of evidence shows that supplementation of copper, iron, and zinc can also enhance host resistance against nematode infection as shown by decreased fecal egg count (FEC) and worm burdens. As such, protein and mineral supplementations can play a major role in sustainable control of parasitic nematode infection and thus reduce reliance on chemotherapic drugs.

代谢性蛋白质和矿物质的添加对小反刍动物内寄生线虫感染有害作用的影响。

内寄生线虫感染可能会对绵羊和山羊的生产造成负面影响。但是，补充蛋白质和矿物质也会影响线虫。本文回顾了目前有关补充蛋白质和矿物质作为控制小型反刍动物线虫感染的重要性的信息。补充蛋白质似乎可以通过将可代谢蛋白质（MP）转移到应对感染的有害作用上来提高宿主的适应能力，从而改善动物的生产和生殖性能。大量证据表明，铜，铁和锌的添加还可以增强宿主抵抗线虫感染的能力，如粪便卵数（FEC）减少和蠕虫负担减少所表明的。因此，
