Simulation of animals´ heat balance

A model is presented which allows one to calculate heat production and heat losses of the animal body, depending on its activity and weather and climate conditions (air temperature, wind speed, precipitation, and solar radiation). This version of the model is a special one, as it includes the active system of thermal regulation, which allows keeping the temperature homeostasis of the animal body using all available means. The external factors influence the thermoregulation system indirectly, by changing the animal´s body total heat. The model identification results and the recommendations concerning the use of the results are presented.
