Methods: A total of 120, five-week old birds were divided into four groups (BF and OX groups were controls fed basal feed and supplemented with Oxycure^®, respectively while BFHS and OXHS were corresponding heat exposed groups). Treatment birds were subjected to heat-stress (38 °C and 40% RH; THI=86), for 4 hours daily for a period of 5 weeks in an environment-controlled walk-in humidity chamber. The mean ambient temperature and RH in the poultry house were 24.6 °C and 54%, respectively (mean THI= 71.53) during the study period.

Result: Significant (P≤ 0.01) negative impact of heat-stress was observed on feed intake, weight gain, FCR and carcass traits of Vanaraja birds, and Oxycure^® supplementation has significantly (P≤ 0.01) improved the feed intake, weight gain, FCR and carcass traits of heat-stressed birds.
