Numerous studies confirm that amino acids improve production performance,enhance body health,and maintain high production efficiency in dairy cows. However,due to the unique digestive structure of ruminants,amino acids often require rumen-protected technology to increase intestinal absorption. Under the current downturn in the dairy industry, scientific utilization of rumen-protected products is essential to reduce costs and improve efficiency,thereby promoting dairy industry development. This paper reviewed the characteristics of rumen-protected amino acids,their research progress in dairy cows,and summarized its applications,providing a theoretical basis and technical guidance for their rational use., authors=CHU Lili, authorsList=CHU Lili, authorCompany=Zhucheng Zhigou Animal Husbandry and Veterinary Workstation,Weifang Shandong 262200, correspAuthors=null, authorNote=null,

articleAbstract=蛋白质营养的实质是氨基酸营养。大量研究证实,氨基酸能提高奶牛生产性能、改善机体健康,维持奶牛高效生产性能。然而,由于反刍动物独特的消化结构,通常需对氨基酸进行过瘤胃保护以提高小肠吸收率。在当前奶业行业低迷情况下,亟需科学利用过瘤胃产品节本增效,促进奶业可持续发展。本文综述过瘤胃氨基酸的特点及其在奶牛中的研究进展,并对其应用进行总结,为其合理使用提供理论依据和技术指导。,
