Heat stress results from a negative balance between the net amount of energy flowing from the animal’s body to its surrounding environment and the amount of heat energy produced by the animal. Poultry seems to be particularly sensitive to temperature-associated environmental challenges, especially heat stress.
It has been suggested that modern poultry genotypes produce more body heat, due to their greater metabolic activity as the temperature rises more and more, the bird’s body attempts to maintain its thermal homeostasis, increased levels of reactive oxygen species (ROS) occur. Therefore, the body enters a stage of oxidative stress and compromise the normal functioning of various organs of the body.
