Effects of Ambient Temperature on the Performance and Thermoregulatory Responses of Commercial and Crossbred (Brazilian Piau Purebred Sires × Commercial Dams) Growing-Finishing Pigs

Abstract: The study aimed at evaluating the effects of high ambient temperature (HT: 30 °C) on the thermoregulatory responses and performance of commercial and Piau crossbred (Brazilian Piau breed sires × commercial genotype dams) growing pigs. Commercial and Piau crossbred pigs were reared under thermoneutral (TN: 22 °C) or HT conditions during a 14-day experimental period. Feeding (daily) and animals (beginning and end) were weighted to obtain performance parameters. Skin and rectal temperatures, respiratory rate, and… Show more

“…Hogs rely on peripheral vasodilation and panting to dissipate excess heat. However, due to their few functional sweat glands and the subcutaneous layer of backfat that impedes heat loss, they are susceptible to thermal shock that can also lead to death ( Figure 2 ) ( 28 30 ).…”
