The growth performance of animals is often affected by extreme environmental conditions. In the case of swine, generally a cold environment will increase feed intake as the pig strives to maintain body temperature, while warmer environments may reduce growth, increase body maintenance demands, and subject the animal to environmental stress. Confinement houses are widely used as a primary means of modifying the environment to improve conditions for the growth of swine. Environment in these structures is usually controlled by natural or mechanical ventilation and by insulation for cold climates and limited use of evaporative cooling for summertime conditions.
