摘　　要：随着对反刍家畜蛋白质营养体系的深入研究,反刍家畜饲粮、瘤胃及小肠中氨基酸的组成和比例也得到进一步探索。赖氨酸作为一种限制性氨基酸,在反刍家畜生长、生产性能、瘤胃发酵及微生物区系组成等方面有着重要影响,赖氨酸还会影响其他营养物质的代谢。本文基于近些年来国内外的相关研究,总结了赖氨酸的生理功能、合成与分解代谢,以及赖氨酸对反刍家畜瘤胃微生物、消化代谢和生产性能的影响,为赖氨酸在反刍家畜的生产与应用上提供理论依据与技术指导。With the in-depth research on the protein nutrition system in ruminant livestock,the amino acid composition and ratio in ruminant livestock diet,the rumen and small intestine have been further explored.Lysine is one of the limiting amino acids,which has an important influence on the growth performance,production performance,rumen fermentation,and microbial communities of ruminant livestock,and lysine can also affect the metabolism of other nutrients.In this paper,combined with the current research at home and abroad,the physiological functions of lysine,the synthesis and catabolism of lysine,and the effects of lysine on ruminant microbes,digestion and metabolism,and production performance were briefly summarized,which provide theoretical foundation and technological guidance for lysine application in ruminant husbandry industry.
