摘　　要：牛奶营养品质低下已成为我国奶业健康发展所面临的严峻挑战。乳脂肪是决定牛奶营养品质的主要物质之一。调控乳腺内脂肪酸转运、从头合成、酯化和脂滴形成的相关基因的遗传多态性对乳脂肪的成分及含量具有重要影响。本文综述了这些基因的遗传多态性及其对乳脂肪生成的影响,旨在为明确奶牛乳腺脂肪酸形成调控网络提供理论基础和研究思路。Low nutritional quality of cow＇s milk has increasingly become a severe challenge in dairy industry in China.Milk fat is the main substances to determine the nutritional quality of cow＇s milk.Milk fat could be affected by the polymorphisms in many genes from the fatty acid uptake,de novo fatty acid synthesis,the triacylglycerole biosynthetic,and milk lipid droplets pathway in dairy cow＇s mammary gland.In this paper,we summarized the gene polymorphism regulation of bovine milk fatty acid composition.We hope that this review will provide a reference for further study on the regulatory mechanism of milk fat formation and improve the nutritional quality of cow＇s milk.
