Abstract
In order to meet demand and ensure greater productivity in farming systems, growers have used new technologies on limiting factors such as nutrition, physiology and health of animals. Among the physiological factors, homeostasis can be considered one of the most relevant when it comes to homeothermic animals. Thus, the thermal environment is of paramount importance in the well-being and productivity of animals, but it has been neglected by mainstream producers. Several surveys have been conducted to evaluate the influence of thermal environment on animal performance and seek alternatives which make the environment conducive to pigs. This study aims to evaluate the influence of heat stress on animal performance, mortality rate, average weight at slaughter, carcass characteristics, carcass cuts, physical and chemical quality of meat, blood test for parameters physiological (T3 and T4), animal behavior under different conditions to be submitted and the influence of pre-slaughter stress in different thermal conditions q animals should be subjected. Will be used 30 barrows (Topigs) distributed in a completely randomized design consisting of three treatments with ten replicates and one animal each. (AU)
