| 摘 要： | 酪蛋白是乳蛋白的主要成分,不仅营养丰富,且其水解产物对机体有重要调节作用。影响酪蛋白含量的因素主要有遗传、泌乳阶段、日粮营养水平及其组成等,其中通过调控日粮营养水平来提高乳中酪蛋白含量是一种较为常见的技术手段,对提高饲料利用率及改善乳品品质具有重要意义。作者综述了不同日粮营养水平对奶牛乳中酪蛋白含量的影响,以期为生产实践中提高奶牛乳中酪蛋白含量提供理论基础。

| Abstract: | Casein is the main component of milk protein which has high nutritional value and plays an important regulatory role in the organism.The factors such as genetic,lactation stage,breeding and diet affect the content of casein.Regulation of diet is a common method to improve the content of milk casein,which also has a significant effect to optimize diet utilization and the quality of dairy products.The paper summarizes the influence of different diet nutrition levels on the content of milk casein and provides a theoretical foundation for improving the content of milk casein in dairy cows. |
