Twenty-four castrated male DLY (crossbreeds between LandracexYorkshire sows and Duroc boars) pigs were selected from eight litters (body weight: 79.0 [+ or -] 1.5 kg) from a pig breeding farm in Beijing, China, among which three pigs from each litter were allocated to one of three treatments: constant ambient temperature at 22[degrees]C and ad libitum feeding (CON, n = 8); constant high ambient temperature at 30[degrees]C and ad libitum feeding (H30, n = 8); and constant ambient temperature at 22[degrees]C and pair-fed with the diet consumed by H30 (PF, n = 8).
