Online published on 20 May, 2023. Abstract An experiment was conducted in 180 day-old Vencobb 400 strain broilers chicks to determine the effects of Vitamin E, Vitamin C and Seleniumin different combinations on blood haematological, biochemical, liver enzyme, serum electrolyte, heat shock protein, antioxidant profile and carcass quality of broiler chickens during heat stress. Chicks were distributed randomly into 5 groups having 36 chicks in each (3 replicates of 12 chicks). Control group (T0) was fed with basal ration and other four groups were offered basal ration and drinking water was supplemented with 100 mg/ltr vitamin E + 0.2 mg/ltr Se (T1), 100 mg/ltr vitamin E + 0.3 mg/ltr Se (T2), 100 mg/ltr vitamin E + 100 mg/ltr vitamin C (T3) and 200 mg/ltr vitamin E + 200 mg/ltr vitamin C (T4). Result showed significant difference (P<0.05) in Hb and WBC level. Supplemented groups showed significantly better serum glucose and protein content. Serum chloride, liver enzymes, erythrocytic antioxidants were significantly better (P<0.05) in T1 and T4 groups than other groups. Heat shock protein was found to be significant (P<0.01), whereas, no significant difference (P>0.05) was recorded in carcass characteristics viz. prime cuts percentage and giblet weight. The study revealed that blood haematological, biochemical, liver enzymes, serum chloride, antioxidant profile and heat shock protein were better (P<0.05) in the supplemented groups as compared to control. However, due to more pronounced effect of T1 and T4 groups, vitamin E and Selenium @ 100mg/ltr and 0.2 mg/ltr, respectively and vitamin E and vitamin C @ 200 mg/ltr each can be supplemented in broiler rations for better performance and health during heat stress.
