PROTECTIVE EFFECTS OF EMBLICA OFFICINALIS AND YEAST SELENIUM AGAINST HEAT STRESS IN BROILER CHICKENS: PERFORMANCE, HEMATOBIOCHEMICAL, ANTIOXIDANT IMMUNOLOGICAL, CORTICOSTERONE AND PATHOLOGICAL STUDY

Abstract

This study was conducted to assess the protective effect of dietary supplementation of Emblica officinalis and yeast selenium on general performance, hematobiochemical, antioxidant studies, immunological, corticosterone and pathology of broiler chickens under heat stress. Total 45 broiler chickens were divided into 03 equal groups with 15 birds in each group. Group G-I was served as control fed with basal diet only, while G-II was treated with basal diet + E. officinalis fruit powder @ 0.3 % of feed and G-III was treated with basal diet + yeast selenium @ 0.3 mg/kg of feed. Dietary supplementation of E. officinalis fruit powder and yeast selenium alleviated heat stress adverse effects in terms of general performance, hematobiochemical, antioxidant, immunological, corticosterone and pathological parameters. However, the better results were found with yeast selenium supplementation compared to other groups.
