Comparative analysis of various sources of selenium on the growth performance and antioxidant status in broilers under heat stress

Abstract The supplementation of Selenium-enriched probiotics is effective in reducing oxidative stress and maintaining meat quality stability broiler chicken especially under heat stress. An experimental study was conducted to perform Comparative analysis Selenium yeast with inorganic Se broilers A total 120 chicks one day were assigned 4 groups each consisting 30 fed on same basal diet but different selenium sources. group D1 not supplemented source (Negative control), D2 (Sodium selenite 0.22mg/Kg starter phase 0.15mg/Kg finisher phase), D3 commercially available organic (Seleno-methionine phase) D4 self-developed (Se-enriched phase). performance parameters i.e. feed intake (FI), live body weight (BW) FCR significantly (p>0.05) effected by the (p<0.05) phase. serum level groups. Higher value (58.20±0.06) recorded group. Similarly lower for higher (11.36±0.08). However Paraoxonase (PON) (13.24±0.01) (13.33±0.03). Comparatively enriched increased accumulation improved antioxidant system. Glutathione peroxidase (GPx) found (12.333±0.03) followed D3, respectively. Whereas superoxide dismutase (SOD) (0.1437±0.003) (0.1457±0.002). bird’s survival rate. Birds showed deposition better capacity as compared other sources selenium. Se-enriched displayed an result tissues, capacity, tenderness immune response
