Extract

The stress of high environmental temperature may have a deleterious influence on the performance of broiler chickens by reducing feed intake, live weight gain and feed efficiency. Exposing chicks to 36-38°C for 24h at 5d of age reinforces the resistance of older (6 to 7 wk-old) broilers to heat stress (De Basillo et al., 2003). Several studies have revealed that antioxidant nutrient supplementation especially vitamin C and E can be used to alter the negative effect of environmental stress (NRC, 1984). Combination of antioxidant vitamins generally shows greater antioxidant activity than that of each component alone. The objective of this study was to investigate the effects of early age thermal conditioning and vitamin C, E supplementation on performance, carcass characteristic in broiler chickens reared under heat stress.
