胃肠道-肝脏-乳腺协同调节奶牛乳成分的机制

Mechanism of Gastrointestinal Tract-Liver-Mammary Gland Co-Regulating Milk Components of Dairy Cows

作为牛奶营养价值评定的关键营养性指标,乳蛋白、乳脂及乳糖的合成需要机体多组织器官协同完成,同时也受多条信号通路的调控。本文综述了乳蛋白、乳脂和乳糖的合成过程,强调了胃肠道-肝脏-乳腺协作在乳成分合成中的作用,并阐述了乳成分合成的分子调控机制,以期为改善牛奶成分的营养调控策略提供参考。

The synthesis of milk protein,milk fat and milk lactose,as the key nutritional indices in the evaluation of milk nutritional value,requires the coordination of multiple tissues and organs,and is also regulated by multiple signaling pathways.This article reviewed the synthesis process of milk protein,milk fat and milk lactose,emphasized the role of gastrointestinal track-liver-mammary gland cooperation in milk component synthesis,and expounded the molecular regulatory mechanism of milk component synthesis,in order to provide reference for improving the nutritional regulation strategy of milk components.
