Physiological response patterns of (A) body temperature (significant difference analysis was performed on the same breed at different temperatures), (B) body temperature deviation, (C) respiratory rate, and (D) shivering frequency in LW and MS pigs exposed to temperatures of 25 °C and 4 °C for four days. The results were expressed as mean ± SEM (n = 3). Statistical significance was determined using the two-tailed unpaired Student’s t-test, with ** p < 0.01 and * p < 0.05 denoting significance. A,B Different capital letters represent significant differences in LW pigs at 4 °C (p < 0.05). a,b Different lowercase letters represent significant differences in MS pigs at 4 °C (p < 0.05). LW and MS represent Large White pigs and Mashen pigs, respectively; 25 and 4 indicate 25 °C and 4 °C, respectively.
