摘　　要：脂肪酸是奶牛重要的营养素之一,能够有效提高日粮能量浓度,提供必需脂肪酸,增强脂溶性养分的吸收。在奶牛围产期和泌乳高峰期,脂肪酸能够满足奶牛的能量需求,避免或缓解机体能量负平衡,改善奶牛的生产性能和乳品质。文章总结2021年奶牛脂肪酸相关文献,综述日粮中不同来源脂肪酸对奶牛生产性能、乳品品质、抗炎机制、繁殖性能、瘤胃菌群和甲烷排放等方面的影响,讨论奶牛脂肪酸的现状及其发展趋势,为脂肪酸在奶牛生产中的应用提供参考。Fatty acids is one of the important nutrients for dairy cows, which can increase the energy concentration of diet,provide essential fatty acids, and enhance the absorption of fat-soluble nutrients. Fatty acids can meet energy requirements avoid or alleviate negative energy balance in body, improve the performance of cows and milk quality during the periparturient and peak lactation periods. The paper summarizes literature related to fat(fatty acids) in dairy cattle in 2021,mainly concerning the effects of different sources of fatty acids in diets on dairy cattle performance, milk quality, antiinflammatory mechanisms, reproductive performance, rumen flora and methane emissions, discusses the present situation and development trend of fatty acids in dairy cattle, to provide reference for the application of fatty acids in dairy cattle production.
