摘要： 胃肠道线虫感染是限制反刍动物生产性能提高的重要问题。目前,国内外利用化学药物防控胃肠道寄生虫感染取得了显著效果,但是牛羊很快会产生抗药性,而且药物残留通过畜产品损害人类健康,所以,昂贵的新药开发费用和食品安全问题促使研究寻求新的驱虫方法。研究表明,单宁含量高的植物具有显著的抗虫作用,摄食单宁含量高的植物可以降低牛羊粪便虫卵数、体内成虫数和成虫繁殖力。基于大量研究,综述牛羊胃肠道线虫感染对宿主物质代谢的影响、高单宁植物的抗虫效果以及植物单宁抗虫机理的推测。

Abstract: Gastrointestinal nematodes infection restricts performance of ruminants.Although repeated use of anthelmintic drugs worldwide has acquired significant effects on controlling infection,the risk of drug resistant and residues in foods are prevalent and harmful to human health and sustainable agriculture development.Therefore,higher cost of producing anthelmintic drugs and concerns of food safety urge researchers to exploit alternative strategies.Many studies have identified that tannins-rich plants could decrease fecal egg counts,worm burden and fecundity.This review focused on effects of gastrointestinal nematodes infection on nutrients metabolism,and mechanisms of tannins on gastrointestinal nematodes resistance in ruminants.

Key words: Nutritional modulation, Ruminant, Gastrointestinal nematodes, Plant-derived tannins
