In the changing climate scenario, heat stress is the most detrimental factor which negatively influences livestock production. This may lead to severe economic consequences in livestock industry. The negative impacts of high temperature stress are generally aggravated when it is coupled with high relative humidity. Every animal produce optimally under its own thermoneutral zone. Different factors of climate such as air temperature, humidity, wind velocity, and solar radiation have prominent effect in influencing the homeostasis in animals. The interaction of these climate variables and the animal biological system lead to drastic changes in the production performance of the animal. This has paved the way for the scientific community to look for a range of thermal indices to specific locations to quantify heat stress response in livestock.
