Advances in the Application of Methionine and Its Small Peptides in Dairy Cows
Methionine is one of the most important limiting amino acids in dairy cows,and its deficiency in dairy cows'diets can lead to reduced protein availability and environmental pollution.Small peptides containing methionine as methionine supplement has higher utilization efficiency than free methionine,and its feeding value in dairy cow production is worthy of further exploration and application.In this paper,the structure,absorption,metabolism and biological function of methionine and its peptides were reviewed,the application progress of methionine and its peptides in dairy cow production was summarized.The possible mechanism of methionine and its peptides affecting the performance of dairy cows was emphasized in order to provide theoretical basis for the application of methionine and its peptides in dairy cow breeding.
