“…Supplementation of the diet with Se-yeast significantly affected egg weight, egg yolk and albumen weight as well as the Haugh units in eggs from Hy-Line Brown chickens [18]. Baylan et al also reported that the majority of indicators of egg quality are positively influenced by selenium yeast supplementation in Japanese quails [19].…”

The objective of this experiment was to investigate the selenium distribution in eggs from hens fed diets supplemented with Se from sodium selenite (SS) or selenium-enriched yeast (SY). One-day-old female chickens of Hy-Line Brown breed were randomly divided into four groups according to dietary treatments and, for the subsequent 9 months, were fed diets which differed only in the form or amount of Se supplemented. During the whole experiment, group 1 (control) was fed basal diet (BD) with only background Se level of 0.13 mg/kg dry matter (DM). Diets for groups 2 and 3 consisted of BD supplemented with an Se dose of 0.4 mg/kg DM either in the form of SS or SY, respectively. Group 4 was fed BD supplemented with 0.9 mg Se/kg DM from SY. After 9 months of dietary treatments, the Se levels in egg yolk and albumen from hens fed unsupplemented diet were almost identical whereas eggs from hens given diet supplemented with SS showed significantly higher Se deposition in yolk than in albumen (P < 0.01). On the other hand, the feed supplementation with Se doses 0.4 or 0.9 mg/kg DM from SY resulted in significantly higher Se concentration in albumen than in yolk (both P < 0.001). The total Se amounts in whole eggs from hens in groups 1, 2, 3 and 4 were 5.1, 14.4, 22.7 and 31.6 μg Se/egg thus demonstrating the significantly higher (P < 0.001) selenium deposition in eggs from hens given feed enriched with SY than from birds fed diet with equivalent SS dose. Regardless of dose and source, the selenium supplementation to feeds for groups 2, 3 and 4 resulted in significantly increased α-tocopherol concentration in egg yolk compared to control group 1 (P < 0.001). The presented results demonstrate the different pattern of Se distribution in egg mass when laying hens are fed diets supplemented with inorganic or organic selenium sources.

“…It has described that organic selenium supplementation in commercial poultry feeds has positive impact (ElSheikh & Ahmed-Nagwa 2006; Baylan et al 2010). The use of Se-enriched yeast in laying hen diets increases selenium content of egg (Utterback et al 2005;Gajcevic et al 2009;Attia et al 2010).…”

A study to examine the impact of selenium forms on productive traits and egg selenium deposition in Aseel was conducted. A total of 96 selenium-treated 21-week-aged Aseel birds were used, 84 females (1726.25 ± 121.65 g) and 12 males (1973.17 ± 182.84 g) from Lakha, Mushki, Peshaweri and Mianwali varieties. Birds were distributed into four experimental groups (21 females and 3 males/variety), further subdivided into three treatment groups A, B and C with 8 birds each, 7 females and 1 male (4 varieties Â3 Se treatments Â8 birds/treatment). Group A and B were the experimental while, C was a control group. Ration for the birds of group A included 0.3 ppm Se-enriched yeast, group B with 0.3 ppm sodium selenite, while, group C received a basal ration containing no selenium. Experimental birds were maintained separately in battery cages from 22 to 42 weeks. The pullets received Se-enriched yeast (organic source of selenium) supplemented ration gained the sexual maturity earlier (168.61 ± 0.64 d) and represented increased (p .05) body weight (1973.56 ± 3.43 g); egg production (38.17 ± 1.27%); egg mass (112.52 ± 2.63 g); FCR/dozen eggs (3.26 ± 0.06); FCR/kg egg mass (6.77 ± 0.23) and the selenium contents in the whole egg (11.70 ± 0.01 lg), in egg yolk (8.31 ± 0.01 lg) and in egg albumen (3.33 ± 0.01 lg). It is concluded that Se-enriched yeast is more potent than sodium selenite and is a key supplement used to improve production performance and egg-selenium status of Aseel. ARTICLE HISTORY

“…Poor quality results in substantial economic losses to the worldwide egg industry. For example, losses due to poor eggshell quality have been Effects of Cage Stocking ... calculated to be in the order of 6-8% [3] . The egg industry is more dependent on high stocking densities for laying hens and quails either during the rearing or laying phases as a tool to reduce housing and equipment costs per bird.…”
