摘要/Abstract

摘要： 保证奶牛乳品质量对提高产业价值十分重要。乳蛋白含量是衡量乳品质量的重要因素之一,是研究者关注方向之一。赖氨酸作为奶牛必需氨基酸,需从饲料中定期获取,可以改善机体,提高奶牛的生产性能。本文综述赖氨酸改善奶牛乳蛋白合成机制,从赖氨酸与奶牛泌乳性能和乳品质量关系,介绍赖氨酸可以通过改善乳中蛋白质合成效率、改善蛋白质合成底物浓度、调节乳腺细胞活性,抑制乳腺炎症和相关信号通路调节作用,促进赖氨酸在奶牛养殖中的应用,提高乳品质量,保证奶业健康发展,为奶牛场带来更多经济效益。

Abstract: It is very important to ensure the quality of dairy products to improve the industrial value,and milk protein content is one of the important factors to measure the quality of dairy products,which is one of the directions that researchers pay attention to. As an essential amino acid for dairy cows,lysine needs to be obtained from feed regularly,which has a good effect on improving the body,especially on regulating the production performance of dairy cows. This paper reviewed the mechanism of lysine improving milk protein synthesis in dairy cows was summarized in this paper.From the relationship between lysine and milk performance and milk quality,and this paper introduced that lysine could improve the efficiency of protein synthesis in milk,improve the concentration of protein synthetic substrate,regulate the activity of mammary gland cells,inhibit mammary gland inflammation and regulate related signal pathways,so as to promote the application of lysine in dairy farming,improve the quality of dairy products,ensure the healthy development of dairy industry and bring more economic benefits.

Key words: lysine, milk, protein, production performance, milking performance
