摘　　要：赖氨酸作为反刍动物最主要的限制性氨基酸之一,饲粮中添加过瘤胃赖氨酸有助于调控饲粮蛋白质水平,提高氮的转化效率和动物的免疫机能,并可在一定程度上改善动物的生产性能。加工制备方法、饲粮和氨基酸的互作等因素均会对过瘤胃赖氨酸的饲用效果产生影响。本文就过瘤胃赖氨酸在反刍动物生产中的相关研究与应用以及影响其饲用效果的因素进行了综述,以期为今后进一步的研究提供参考,推动反刍动物养殖业绿色健康可持续发展。Lysine is one of the most important limiting amino acids in ruminants,adding rumen-protected lysine to the diet can help to regulate dietary protein level,improve conversion efficiency of nitrogen and immune function of animals,and improve production performance of animals to a certain extent.Factors such as processing and preparation methods,diet and amino acid interaction can affect the feeding effect of rumen-protected lysine.This review summarizes the related research and application of rumen-protected lysine in ruminant production and the factors affecting its feeding effect,in order to provide reference for further research in the future and promote the green,healthy and sustainable development of ruminant production.
