In recent years,with the improvement of living standards,people have higher and higher require-ments for the quantity and quality of meat products.Muscle accounts for 40％to 50％of the carcass weight of livestock and poultry,and is an important source of animal protein for humans.Its development process is regu-lated by genetic,nutritional and gender factors,among which nutrient intake plays a crucial role.Methionine(Met),as the main limiting amino acid for most animal growth,participates in protein metabolism and is one of the commonly used feed additives for livestock and poultry.Therefore,this paper summarized the processes of Met absorption and metabolism and its application in muscle development,combined with the structural composition,development and regeneration processes of muscle,elaborated the mechanism of Met regulation of m、uscle development,and provided a reference for improving animal diet formula and improving meat pro-duction performance.[Chinese Journal of Animal Nutrition,2024,36(5):2856-2871]
