Four feeding trials were conducted to investigate the influence of vitamin C and corn oil supplementation on broiler performance under heat stress. In the first and second experiments, a total of 180 one-day broiler chicks were randomly distributed into three groups. The chicks were raised on open house system during summer season. The birds were fed three levels of vitamin C; 0, 500 and 1000 mg/kg diet, respectively (experiment 1), and corn oil; 0%, 3% and 5%, respectively (experiment 2). The two trials were lasted to 8 weeks. In experiment 3, a total of 180 three-week old broiler chickens were randomly distributed into six combination treatments in environmental chambers at 24º C and constant 35ºC. The birds fed diet supplemented with 0%, 5% corn oil and 5% corn oil with 500 mg/kg diet, respectively. In the fourth experiment, the broiler chickens were randomly distributed into six combination treatments as mentioned in the 3rd trial. The birds were fed diet supplemented with 500 mg vitamin C/kg diet, 3% corn oil and 3% corn oil with vitamin C, respectively. The experiment was lasted to five weeks. Feed intake, body weight gain, and feed conversion ratio were measured. The findings showed that high ambient temperature had negative effect (P<0.05) on broiler performance. The supplementation of vitamin C or corn oil led to a significant improvement (P<0.05) in broiler performance. In general, the supplementation of corn oil or vitamin C improved the BWG and FCR for those birds raised under heat stress.
