利用富硒酵母生产富硒鸡蛋的技术研究

 采用短期饲喂试验研究富硒酵母硒在鸡蛋中的沉积。结果显示，在蛋鸡日粮中加入不同浓度的酵母硒(有机硒)，短期饲喂即可通过鸡本身的生物转化获得含硒量较高，同时又符合食品卫生标准(GB 2762-2005)中硒限量0.5 mg/kg的鸡蛋，且对蛋鸡生产性能无显著影响，对鸡蛋品质也没有不良影响，鸡蛋中的硒主要存在于蛋黄中。

Study on Supplementation with Selenium-rich Yeast on Production of Selenium-enrich Eggs

This research studied the deposition of selenium in eggs with short-term feeding test,with a selenium resource from selenium-rich yeast.Different concentrations of yeast selenium(organic selenium)were added in layers diet,and the results showed that short-term feeding could improve the selenium content in eggs,and complying with the requirements for selenium limit of 0.50 mg/kg in eggs set in the Food Sanitation Standards(GB13105-91).No obvious effect on layers’ production performance and adverse impact were observed in the the egg quality.The results show that the selenium of the eggs mainly existed in egg yolk.
