摘　　要：不饱和脂肪酸主要存在于植物种子、植物油及含油量多的海鱼中,在自然界含量丰富,对人体具有补脑健脑、调节免疫功能、抵抗心血管疾病等重要作用。在反刍动物生产上,富含不饱和脂肪酸的饲粮具有改善反刍动物生产性能、减少甲烷排放和改善产品质量的功能。本文主要针对不饱和脂肪酸对反刍动物生产性能、瘤胃发酵、甲烷排放等方面的影响进行综述,旨在为不饱和脂肪酸在反刍动物营养方面的研究和应用提供参考。Unsaturated fatty acids are mainly found in plant seeds,vegetable oils and marine fish with high oil content.Unsaturated fatty acids are abundant in nature and play an important role in human beings by tonifying brain,improving immunomodulation and fighting combat cardiovascular disease.In ruminant production,diets that rich in unsaturated fatty acids have the function of improving ruminant performance,reducing methane emission and improving the quality of animal products.This paper mainly summarized the effects of unsaturated fatty acids on ruminant performance,rumen fermentation and methane emission for the aim to provide reference for the research and application of UFA in ruminant nutrition.
