Abstract

Housing pigs in a thermal stress environment reduced gain, intake and feed efficiency. Cell mediated immunity responses were lower under the constant heat stress as well as when the temperature was lowered to a thermal neutral temperature for only 4 hours daily. Daily cooling to thermal neutral for 4, 8, or 16 hours improved growth performance. Antibody responses were not altered by temperature fluctuations.; Swine Day, Manhattan, KS, November 10, 1983
