Milk protein is an important indicator to evaluate milk quality. Lysine (Lys) is both a limiting amino acid and an essential amino acid, and plays an important regulatory role in the synthesis of milk protein in dairy cows on a corn-based diet. Lys can improve lactation performance and maintain mammary gland health of dairy cows. However, the detailed molecular mechanism of Lys regulating milk protein synthesis is still unclear. This paper reviewed the research progress on the effects of Lys on lactation performance of dairy cows, especially milk protein synthesis, and introduced the possible mechanism of Lys on milk protein synthesis in dairy cows, so as to provide theoretical reference for improving the precise regulation strategy of lactation nutrition in dairy cows.
Key words: lysine; dairy cows; milk protein synthesis; signaling pathways; molecular mechanism
