The present study was carried out to investigate the effects of the ethanol extracts of propolis (EEP) and vitamin C on body weight (BW), body weight gain (BWG), feed intake (FI), feed conversion ratio and carcass characteristics of broilers exposed to heat stress (at 34 °C)…

The results suggested that heat stress had negative effects on the performance while propolis supplements improved the growth and carcass yield. Dietary EEP supplementation was found to be more effective than dietary vitamin C on performance and carcass characteristics in broilers under heat stress.
