植物甾醇的生理功能及其应用

Physiological function and application of phytosterol

植物甾醇在拮抗胆固醇、预防心血管疾病方面表现出良好的效果,同时还具有调节生长、促进蛋白质合成、抗炎、抗氧化、抗癌、免疫调节及类激素等生理功能,对人和动物无毒害,是我国农业部批准的新型功能性饲料添加剂。本文主要对近年来植物甾醇的调节胆固醇代谢、类激素等生理功能,及其在动物生产中降血脂、改善乳用动物乳成分等应用方面进行综述,为其在畜禽饲料中广泛应用提供参考。

Phytosterol, as a bioactive substance, reduced blood cholesterol and the risk of cardiovascular disease except with other physiological functions such as growth regulation, promotion of protein synthe- sis, anti-inflammatory, antioxidant, anticancer, immune regulation and hormone-like effects. Phytosterol did not show any toxicity to human and animals,and it is a new functional feed additive and has been ap- proved by the Ministry of Agriculture of China. This article generally reviewed the aspects of the physio- logical function of phytosterol like the regulation of cholesterol metabolism, antioxidation, hormone-like effects and application on animal production like hypolipidemic and improving the dairy animals＇ milk com- position. The further research in animal feed additive was suggesed.
