Physiological Reactions Of Poultry To Heat Stress And Methods To Reduce Its Effects On Poultry Production, Narongsak Chaiyabutr

The Thai Journal of Veterinary Medicine

Thermal environment is regarded as the prime factor governing the production because, both the feed consumption and heat production are related closely to the thermal environment. Therefore, heat stress is caused by a combination of environmental and animal factors that result in reduced performance as the animal attempts to cool itself. In this review, the physiological reactions of bodily functions during heat exposure in poultry are described. Thermal panting, the marked response of poultry to heat stress, is compensatory behavior to permit a high rate of evaporative cooling from the respiratory tract. Cardiorespiratory responses to thermal stress show different patterns …
