“…Selenium (Se) is well known to be essential for growth (Yoon et al 2007;Wang and Xu 2008), feather development (Edens et al 2001;Perić et al 2009), immune competence (Cai et al 2012;Liao et al 2012), antioxidant (Peng et al 2007;Zhou and Wang 2011) and reproduction (Poley et al 1937;Leeson et al 2008) of chickens. Inorganic Se salts, such as sodium selenite, are generally supplemented in diets to meet the Se requirement of chickens (Perić et al 2009).…”

An experiment was conducted to investigate the effects of selenium (Se) sources on growth performance and tissue Se retention in yellow chicks fed a conventional corn-soybean meal basal diet. A total of 2250 one-day-old chicks were fed a Se-unsupplemented corn-soybean meal basal diet (containing 0.10 mg of Se/kg) for six days, and then chicks were assigned by body weight to 1 of 5 treatments with 6 replicates of 75 birds each floor pen in a completely randomized design. Broilers were fed the basal diet (control) or basal diet supplemented with 0.3 mg/kg of Se from sodium selenite, Nano elemental Se, Se yeast A or B for 10 days. The results showed that Se sources did not significantly (P > 0.52) affect growth performance. Se sources significantly affected (P < 0.05) Se concentrations in liver and breast muscle, in which chicks fed the diet supplemented with Se yeast B had higher (P < 0.05) tissue Se concentrations than those fed the diet supplemented with sodium selenite or Nano elemental Se. No differences (P > 0.66) were observed in liver and breast muscle Se concentrations among sodium selenite, Nano elemental Se and Se yeast A. Therefore, the new procedure used in this experiment could detect the differences of the effectiveness among Se sources, and Se yeast B was the most effective Se source for yellow broiler chicks.

“…However, feed intake was not influenced (P ≤ 0.05) by the source of selenium, mortality was not affected by the level and source of selenium in the feed. Edens et al (2001) reported no differences in body weight or feed efficiency when broiler chickens were fed diets containing 0.2 ppm Se from sodium selenite or selenium yeast. The utilization of selenium added as sodium selenite in slow-growing laying-type chickens and in fastgrowing broiler hybrids was examined by Zelenka and Fajmonova (2005).…”

ABSTRACT:The effect of dietary supplementation of selenium in an organic form on performance, carcass traits and selenium content in tissues of broiler cockerels Ross 308 was studied. The soya-wheat-maize diet contained 50 mg vitamin E/kg. The experiment was conducted on 810 straight-run broiler cockerels randomly divided into 3 groups: group I -control, without selenium supplement; experimental group: II -0.3 mg Se/kg, Se-enriched yeast was applied as a Se source; III -0.3 mg Se/kg, Se-enriched alga Chlorella as a Se source. The broiler chickens were slaughtered at 42 days of age. In performance traits higher (P ≤ 0.05) live weight of broiler chickens was recorded in the experimental groups (II -2 430.6 g and III -2 425.2 g). There were no significant differences between the groups in feed conversion and mortality. Se-enriched alga had the best feed conversion, and selenium supplementation slightly increased mortality in both experimental groups. No significant differences between the groups were found out in carcass traits and dressing percentage. The content of selenium in breast and thigh muscle, feathers and excrements increased (P ≤ 0.05) in both experimental groups compared to the control group. Higher values in breast and thigh muscle and in feathers were measured in the group supplemented with selenium from Se-enriched yeast, also in comparison with the group supplemented with selenium from Se-enriched alga Chlorella. The broiler chickens receiving Chlorella had a higher (P ≤ 0.05) selenium content in excrements compared to the group with Se-enriched yeast. The selenium concentration in liver was higher (P ≤ 0.05) in both experimental groups compared to the control. The supplement of selenium from Se-yeast and Chlorella in the diet for broiler chickens increased the microelement concentration in muscle.

“…Among varieties, the better body weight in the birds of Lakha may be attributed to the genetic difference (Bell and Weaver, 2005). This improvement may be was due to the fact that organic Se is more bioavailable than inorganic Se (Edens et al, 2000) which obviously resulted in enhanced body growth. Similarly, it is claimed that increase in body weight is linked to the inclusion of organic Se in the diet of broilers (Salman et al, 2007;Upton et al, 2008).…”

A study to investigate the influence of selenium on final body weight and slaughter traits of Aseel was conducted. Threeweeks-old 120 cockerels from Lakha, Mushki, Peshaweri and Mianwali varieties of Aseel were randomly selected and distributed into four groups, 30 cockerels each, subdivided into 3 treatment groups A, B (experimental groups), and C (control group) with 10 cockerels in each treatment. Birds were assigned three experimental diets. The diet for the birds of group A incorporated 0.3 mg/kg Se-enriched yeast and group B included 0.3 mg/kg sodium selenite, while C was fed the diet without Se (control diet). Final body weight, dressed weight, dressing%, eviscerated weight, eviscerated%; chest, thigh and giblets weight; selenium content in chest and thigh in Se-yeast fed birds were significantly increased than those got sodium selenite or control diet. The study concluded that Se-enriched yeast is more effective in improving body weight and slaughtering characteristics of Aseel.
