摘要

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。

Abstract

The essence of protein nutrition is amino acid nutrition. 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.
