摘　　要：在规模化养猪生产中,公猪的精液品质直接影响母猪的繁殖性能,这对猪场的生产成绩非常重要。多不饱和脂肪酸(PUFA)对精子质膜的流动性和脂质过氧化反应的敏感性有重要作用,同时也影响精子的授精能力。研究表明,在公猪饲粮中添加ω-3 PUFA能提高公猪精液品质,但效果重复性还不稳定;公猪饲粮中添加ω-3 PUFA能增加猪精子中ω-3 PUFA的含量和延长精液的保存时间。本文主要综述公猪饲粮中添加ω-3 PUFA对公猪精液品质的影响及其主要的作用机制,为其在现代规模化养猪生产中有效提高精液品质、猪场生产成绩和经济效益提供参考。In modern large-scale pig production,semen quality has a direct impact on reproductive performance of sows and plays a critical role in pig farm's production efficiency.Polyunsaturated fatty acids(PUFA) play a key role in the sperm membrane fluidity and susceptibility to lipid peroxidation.Moreover,PUFA influence the sperm fertilization.Many studies have shown that dietary ω-3 PUFA supplementation improves semen quality,but the reproducibility is not stable.Dietary ω-3 PUFA supplementation can extend the storage time of semen and exert positive effects on sperm fatty acid profile.This paper reviews the effects of dietary ω-3 PUFA supplementation on boar semen quality,and analyzes the respective mechanisms,which can help to improve semen quality,increase productivity and enhance economic return in modern large-scale pig production.
