摘要: 硒(selenium)是人和动物必需的微量元素,它与调节生长、提高机体免疫力、抗癌、抗氧化、抗应激、延缓衰老及防治地方病等有着密切的关系。国内的补硒方法是添加亚硒酸钠,但亚硒酸钠毒性大,吸收转化率低及造成环境污染。近年来,人们逐渐把目光转向毒性小且生物利用率高的有机硒上,其中酵母硒成为研究与应用的热点。

Abstract: Selenium (Se) is an essential trace element for animals and human,it has roles in regulating growth,enhancing immunity,preventing cancer,resisting oxidation and stress,postponing aging and preventing or controlling local epidemic,etc. Sodium selenite is used as the commercial Se source supplement in animal feeds in China. But it was found that sodium selenite had disadvantage of higher toxicity,lower bioavailability and potential environmental pollution. etc. In recent years,great attention has been gradually paid to organic selenium which has lower toxicity and higher biological utilization rate. Selenium yeast has become a hot spot in animal production. The possibilities of selenium yeast as feed additive were discussed in this article.

Key words: selenium yeast; animal production; research; application
