多不饱和脂肪酸对奶牛免疫功能的影响及其机制研究进展OA

Polyunsaturated fatty acids(PUFAs)are involved in key physiological processes of dairy cows,such as lipid metabolism,phospholipid composition of biological membranes,reproduction,immune function and synthesis of bioactive substances.In intensive farming,enhancing the immune function of dairy cows is im-portant for fighting off pathogens and boosting products quality.More and more studies have shown that PUFAs play a key role in regulating the immune function of dairy cows.In this paper,the effects of PUFAs supple-mentation in diets on the regulation of dairy cows'immune function in the latest researches are reviewed.We focus on the effects of n-3 and n-6 PUFAs on immune function and performance of dairy cows,balance of n-3 and n-6 PUFAs in the diets,and the molecular mechanisms of PUFAs.The aim is to deepen the understand-ing of the nutritional roles of PUFAs in the immune system,to come up with nutritional strategies that boost the immune function of dairy cows,and to provide a solid foundation for improving health and performance of dairy cows.[Chinese Journal of Animal Nutrition,2026,38(3):1602-1611]
