摘要
乳蛋白是牛奶中最重要的营养物质,其含量是决定牛奶质量的重要指标。乳蛋白率受遗传、环境、营养和饲养管理等多种因素影响。提高乳蛋白率难度很大,应综合分析,找准原因,采取综合措施来加以改进,主要可从遗传育种、饲养管理及营养等三方面来实施。相对于乳脂率来说,在生产中提高乳蛋白率难度要大,因为乳蛋白的含量受奶牛遗传育种的影响更大。但只要饲料营养配比得当,乳蛋白率水平也会提高。
Lactoprotein is the most important nutrients of milk, its content is an important target to decide the quality of milk. The rate of lactoprotein is affected by genetic, environment, nutrition, feeding management, and many other factors. It is so difficult to improve the rate of lactoprotein that should make generalized analyses, seek the accurate reasons and take comprehensive measures. It mainly may be implemented from the heredity breeding, the raising management and the nutrition and so on three aspects. In opposite to butterfat content, it is harder to improve the rate of lactoprotein in the production, for the content of lactoprotein is more affected by the heredity breeding of cows. But as long as the proportion of feed nutrition is suitable, it is also possible to improve the rate of lactoprotein.
