Studies On The Production Of The Selenium Eggs In Chicks.

[摘要] Selenium (Se), a potent antioxidant, exists in inorganic and organic forms and serves as a dietarysource to replenish its loss from the body either through urine, faecal matter, or sweat. Considering this asconcept experiments on the effects of dietary Se supplementation on hen’s laying performance, egg Secontent.A total of 90 white leghorns laying hens were randomly divided into three dietary groups withthree replicates and ten hens per replicate. Results showed that compared to control group, bodyweightdaily feed intake, feed conversion ratio were significantly improved in SY and SS groups. Conversely, dailyfeed intake, bodyweight, egg mass, egg weight were significantly lower in the SS group than in the SY group.On the other side, selenium concentration were significantly in egg yolk, egg albumen, and whole eggs inSY and then followed by SS groups. Therefore, we concluded that dietary SY supplementation at 0.3 mgSe/kg diet could meet the Se requirement of laying hens for optimum growth and more positive effects onlaying hens and enriched Se content safe for human consumption. Thus, organic Se from SY is more effectivethan inorganic Se from SS.
