Abstract

Abstract: Amino acid is the basic unit of protein synthesis,an important substance for growth and energy metabolism of organisms,and also an indispensable nutrient in feed.According to the taste characteristics of amino acids,they can be divided into sweet amino acids,umami amino acids,sour amino acids and bitter amino acids,collectively referred to as flavor amino acids.Common flavor amino acids mainly include serine,glycine,glutamic acid,aspartic acid and alanine.Recent studies have shown that the application of flavor amino acids as feed additives in pig and chicken production can promote animal growth and intestinal health,alleviate heat stress,improve antioxidant levels and meat quality.Although amino acids have a lot of advantages in feed,excessive addition will cause adverse reactions to animals.Therefore,it is necessary to determine the appropriate addition amount according to the needs of animal growth and development and the gap of amino acid content in feed.Based on this,the authors review the research progress on the application of flavor amino acids in pigs at different growth stages and chickens with different production uses,aiming to provide reference for its future application in pig and chicken production and feed.

Key words: flavor amino acids; pigs; chickens; intestinal health; antioxidant capacity; meat quality
