Abstract： Taurine is a sulfur-containing β -amino acid with multiple biological functions including antioxidant，anti-inflammation，anti-aging， hormone secretion and lipid metabolism regulation， immune function enhancement，and maintenance of intestinal health. This article systematicly reviews the sources，synthetic and metabolic pathways， biological functions of taurine， focuses on elucidating its dose-effect relationships and mechanisms of action in poultry production （broilers， laying hens， ducks，and quails）.This study also systematically evaluates the optimal dietary taurine supplementation levels in poultry feed formulations，providing empirical evidence for precision nutrient supplementation and functional feed development in intensive poultry production systems. In broiler production，dietary inclusion of 0.05% to 0.25% taurine significantly enhances average daily gain （ADG） and feed conversion ratio （FCR），while effectively mitigating oxidative stress-induced muscular damage under chronic heat stress conditions. For laying hens， supplementation with 0.05% to 0.3% taurine demonstrates multifunctional benefits including improved egg production rate，enhanced eggshell integrity，and attenuation of hepatic lipid deposition.Notably， species-specific requirements were identified，with recommended taurine inclusion rates of 0.1% for ducks and 0.05%-0.1% for quail in formulated diets.These findings establish a scientific basis for optimizing taurine utilization efficiency and advancing practical applications in modern poultry nutrition strategies.

牛磺酸又名牛胆碱、牛胆素、牛胆酸，是一种含硫β-氨基酸，以游离形式存在于大多数哺乳动物组织中，是动物体内最丰富的游离氨基酸之一[1]。（剩余31764字）
