Abstract: Livestock experience various types of stressors throughout their lifetime. Thermal stress imposed by fluctuations in environment temperature, that extend both above and below the thermoneutral zone of an animal, remains the major concern affecting animal production. The adaptation of the animals towards change in climate is mainly related to physiology and its adaptation to the environment. Climate change has adverse effects on animal reproduction and production when animal is subjected to heat and cold stress conditions. The endocrine system is responsible for controlling the stress response, and rapid and appropriate growth is one of the elements of greatest economic importance towards production. This review focuses on the endocrine responses to thermal stimuli during passive heat or cold exposure, with particular responses to the changes in the body core temperature. Activation of the neuroendocrine system affects the secretion of hormones and neurotransmitters which act collectively as response mechanisms that allow them to adapt to stress.
