Effect of selenium sources on growth performance and tissue selenium retention in yellow broiler chicks

Abstract

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.

Effect of Dietary Modulation of Selenium Form and Level on Performance, Tissue Retention, Quality of Frozen Stored Meat and Gene Expression of Antioxidant Status in Ross Broiler Chickens

“…Another limitation of adding selenite to feed is the short period storage of Se in the animal’s body [40]. Our results of Se retention in tissue in accordance with those of [41], who demonstrated that broiler chicks fed on dietary organic Se had higher ( p < 0.05) Se content in breast muscle and liver than those fed diets fortified by SeS. [36] also proved that the contents of Se in liver and muscles were affected by dietary Se supplementation, and retention of Se was increased when organic Se was supplemented as compared with inorganic Se.…”

Prophylactic impact of nano-selenium on performance, carcasses quality, and tissues' selenium concentration using reversed-phase high-performance liquid chromatography during microbial challenge in broiler chickens

“…Liu et al . [ 46 ] recorded that supplementing broilers with 0.3 ppm NS improved growth and performance over Se. Ahmadi et al .…”

“…Kumaran et al [45] reported that NS revealed better improvements in growth performance compared to sodium selenite when used in the ration of Vencobb broilers. Liu et al [46] recorded that supplementing broilers with 0.3 ppm NS improved growth and performance over Se. Ahmadi et al [47] reported improved performance, immunity, and carcass characteristics without any pathological alternations in organs and tissues of broilers supplemented with 0.2, 0.3, 0.4, and 0.5 ppm of NS.…”
