脂肪酸功能及其在养猪生产中应用的研究进展

Research Progress on the Function of Fatty Acids and Application in Pig Production

脂肪酸是猪饲料中的一种重要营养成分,包括短链脂肪酸、中链脂肪酸和多不饱和脂肪酸等多种类型,它们除了提供能量外还对猪的肠道微生态、机体代谢、免疫机能、繁殖性能等具有调节作用。文章简述了不同饲料原料中脂肪酸的含量、脂肪酸的主要生物学功能及其在养猪生产中的应用效果,以期为养猪生产中合理应用油脂和脂肪酸提供依据。

Fatty acids are important compositions of nutrient,including short-chain fatty acids,medium-chain fatty acids and polyunsaturated fatty acids.They play a role in optimizing intestinal microflora,modulating nutrient metabolism,improving immunology and reproductive performance of pigs except for providing energy.This paper reviewed fatty acid profile of feed ingredients,basic biological functions of different variety of fatty acids and its application in swine industry to provide evidences for better using lipids and fatty acid in pig diet.
