摘　　要：随着我国饲料全面禁抗的实施,饲料营养活性物质成为当下研究热点。乳腺合成乳脂的调节过程受到多方面因素的共同影响,目前通过饲料营养活性物质调节乳脂合成研究受到广泛关注。本文从奶牛瘤胃微生物氢化以及瘤胃发酵2个方面,探讨了饲料营养活性物质对乳脂合成调节机制的影响,旨在为通过饲料营养活性物质改善奶牛生产性能提供参考。With the implementation of a total ban on antibodies in feeds in China,nutrient⁃active substances in feeds have become a hot spot for research nowadays.The regulation of milk fat synthesis in the mammary gland is influenced by various factors,and the study of the regulation of milk fat synthesis by the addition of nutrient⁃active substances in feed has received much attention.In this paper,the effect of feed nutrient⁃active substances on the regulation of milk fat synthesis was investigated from two aspects:rumen microbial hydrogenation and rumen fermentation in dairy cows,with the aim of providing a reference for improving the production perform⁃ance of dairy cows through feed nutrient⁃active substances.
