Effects of dietary supplementation of bioactive selenium on performance, egg quality and selenium content in the egg yolk of laying hens
This study was designed to evaluate the effects of bioactive selenium on performance, egg quality and selenium content in the egg yolk of laying hens. The healthy Roman grey laying hens with similar body mass and laying rate were selected as the testing objects. All hens were fed with corn-soybean m...

| description | This study was designed to evaluate the effects of bioactive selenium on performance, egg quality and selenium content in the egg yolk of laying hens. The healthy Roman grey laying hens with similar body mass and laying rate were selected as the testing objects. All hens were fed with corn-soybean meal-based diets for 7 d and then assigned to corn-soybean meal-based diets containing 0 (as the control group), 0.6%, 0.8%, and 1.0% bioactive selenium for 35 d, respectively. The results showed that: 1) When compared with the control group, there were no significant differences in production performance as dietary bioactive selenium contents increasing from 0.6% to 1.0% (P＞0.05). 2) When compared with the control group, no remarkable differences in eggshell thickness, eggshell strength, egg yolk mass and Haugh unit were observed among all the bioactive selenium-added groups (P＞0.05). In general, the thick albumen height increased in the 0.6% to 1.0% bioactive selenium groups on 7 and 21 d. Meanwhile, a significant increase of yolk percentage in bioactive selenium groups was observed relative to the control group on 28 d (P＜0.05). 3) The selenium content in the egg yolk increased linearly with the increase of dietary bioactive selenium contents (P＜0.05). In conclusion, dietary bioactive selenium has no significant effect on laying hen’s performance, but to some extent, it can improve the laying rate, egg quality and increase the selenium content in yolk. |
