摘要 [目的]探索饲喂富硒益生菌对蛋鸡生产性能和鸡蛋中硒含量的影响。[方法]将乳酸菌YQRS菌株和酵母菌FJYJM3菌株在含有亚硒酸钠的培养基中混合培养，并收集菌体进行蛋鸡饲喂试验。试验过程中定时记录每组蛋鸡的生产性能及鸡蛋的总硒含量。[结果]结果表明，在日粮中添加活的益生菌、灭活的益生菌、以及添加亚硒酸钠对蛋鸡的生产性能均无显著影响（P≥0.05），但均能提高鸡蛋内的硒含量，且硒含量差异显著（P≤0.05）。与对照组比较，在日粮中添加亚硒酸钠、灭活的益生菌、活的益生菌，鸡蛋中硒含量分别提高了38.26%，56.12%，63.27%，说明在日粮中添加活的富硒益生菌可以显著提高鸡蛋中的硒含量。[结论]因此富硒益生菌为高硒蛋的生产提供新的途径，也为绿色养殖提供了新的养分。

Abstract [Objective] The aim was to explore the effects on production performance of laying hens and selenium content of eggs by feeding Seriched probiotics. [Method] The strain of yeast FJYJM3 and the strain of Lactobacillus YQRS were mixed cultivated in medium containing sodium selenite， then collecting the thallus to conduct the test of feeding laying hens. Production performance of laying hens and selenium content of eggs in each group were recorded on time. [Result] The results showed that there are no significant effect on production performance in diets supplemented with activated Seriched probiotics and inactivated Seriched probiotics and sodium selenite（P≥0.05）. But all groups could increase the selenium content and there are significant effect on selenium content of eggs in activated Seriched probiotics group and inactivated Seriched probiotics group and sodium selenite group（P≤0.05）. Compared with the control group， the diets supplemented with sodium selenite， inactivated Seriched probiotics， activated Seriched probiotics， selenium content of eggs were increased by 38.26%， 56.12% and 63.27%. Therefore the diet supplemented with activated Seriched probiotics could significantly improve the selenium content in egg. [Conclusion] Seriched probiotics provide a new way for production of high selenium eggs， and new nutrients for the green culture.

硒最开始被列为有毒物质，一直到1957年后才被证实为机体内必需的微量元素[1]。硒是体内谷胱甘肽过氧化物酶的重要组成成分，具有抗自由基、抑癌抗癌、延缓衰老、提高机体免疫力、解除重金属中毒和维持正常繁殖等各种功能[2]。同时，还可以提高热应激和运输应激以及奶牛抗氧化酶能力，从而减缓并改善奶牛因为应激而引起的氧化损伤[3-4]。富硒的菌株是通过生物转化将有毒的无机硒转变成无毒的有机硒，成本较低、生物利用率较高、硒含量较高、对环境污染小等[5]。……
