摘　　要：过瘤胃氨基酸可以直接为奶牛提供理想的小肠氨基酸,能够提升奶产量和乳品质,对提高蛋白质利用效率,缓解奶牛夏季热应激,减少环境污染具有重要意义。本文综述了过瘤胃蛋氨酸和赖氨酸对奶牛产奶量、乳品质、采食量和蛋白利用率等的影响,并从奶牛日粮类型及泌乳期等方面论述了过瘤胃蛋氨酸和赖氨酸在生产中的注意事项,以期为奶牛健康生产提供参考。Rumen-protecte amino acids can directly provide the ideal absordable amino acids in the small intestine for dairy cows. It can improve milk yield and milk quality, significantly improve the utilization of the crude protein, relieve the heat stress and decrease the pollution to the environment . This paper reviewed the effect of rumen-protected lysine and rumen-protected methionine on milk production, milk quali- ty, feed intake and the utilization of protein, and also discussed the considerations for the use of rumen-protected rnethionine and lysine from the aspect of the ration type of diary cows and the cows lactation stage.
