Present investigation was conducted to unwind the effect of heat load index (HLI) and suitable nutrient supplement to combat the adverse effect using 24 Deccani females divided randomly into 4 groups (viz., Control (C), T-1 (3ml of 10% Zinc Sulphate), T-2 (1ml of 0.1% Selenium) and T-3 (60mg Vitamin E daily)) at Hayathnagar Research Farm of ICAR-Central Research Institute for Dryland Agriculture, Hyderabad, India. All environmental variables were recorded at 30 min intervals using automatic weather station and in sheep, physical, physiological, biochemical, hormonal and anti-oxidant profile was determined monthly. HLI was significantly correlated with various physiological, biochemical and bio-molecular parameters, however, catalase and cortisol may be considered as best HLI indicators in the sheep (r=0.911** and 0.864**, respectively). Highly significant correlation between HLI and average daily weight gain (r=0.817**), suggest that HLI significantly controls the growth rate thereby affecting final body weight.
