Research Advance in Interaction of Milk Fat and Protein Synthesis in the Mammary Gland of Dairy Cows

Milk fat and protein are important parameters for the quality of milk. Precursors of milk protein and fat entering the mammary gland directly influence the synthesis of milk protein and fat. Whether there is synergy or competition between milk protein and fat synthesis in utilizing those precursors and the balance model and regulation intersection of the milk precursors are the key points to investigate the synthesis mechanism of milk protein and fat in the mammary gland of cows fed under certain diet condition. They are also the key measures for optimization of milk protein and milk fat synthesis in the mammary gland for further improving milk quality of dairy cows. This paper studied recent domestic and foreign research,and reviewed the interaction of milk fat and protein synthesis in dairy cows mammary gland in order to promote further research on this area.
