Advances in Branched-Chain Amino Acids in Low-Protein Diets for Broilers
摘要
Abstract
Maintaining the balance of branched-chain amino acids(BCAA)is crucial for regulating the sugar metabolism,lipid metabolism and protein synthesis in broilers.Low-protein diets are prone to causing an imbal-ance in the BCAA ratio,negatively affecting growth performance of broilers.The BCAA requirements of broil-ers are influenced by variables such as feed ingredients,growth and development stage,and productivity target.Consequently,this paper synthesized the research advancements from domestic and international sources to de-lineate the metabolic mechanism of BCAA and recommended BCAA ratios in broilers.Considering the antago-nistic effects of BCAA and the differences in the digestive dynamics of various amino acid forms,this review summarized the characteristics of BCAA contents in feed ingredients and their application in low-protein diets for broilers,thereby offering theoretical support for future assessments of BCAA requirements in enhancing broiler growth and muscle protein deposition.[Chinese Journal of Animal Nutrition,2025,37(7):4201-4208].关键词
