The response of pigs to thermal stress consists, mainly, of the intensification of heat dissipation byevaporation through the respiratory tract, followed by reduction in food consumption, with aconsequent reduction in energy intake, constituting an effort by the animal to reduce heatproduction metabolic. Many of these physiological and metabolic responses lead to lower growthrates, poor feed utilization efficiency and changes in carcass composition. Pigs are animals withexcellent levels of production and reproduction, but one of the challenges of swine farming ismainly related to maximum exploitation of their genetic potential. When confined in intensivesystems, the animals are put under adverse conditions, thus, they change their behavior in ageneral way and mainly in relation to the food intake, which is changed, occurring then fall in theirzootechnical indexes, mainly by the changes in the habits feed. Thus, the objective of this work isto present a review on the influence of temperature variation on the production and well-being ofpigs, and pointing out the main physiological changes that occur with pigs submitted to theseconditions.
