Individually caged, F1 gilts (N=3) were adjusted for a week given ad libitum commercial diet and water supply in an environmentally controlled chamber, after which the THI (65, 71, 77, and 83) was elevated every three days for a total of 12 days. Physiological responses [respiration rate (RR), pulse rate (PR), rectal temperature (RT)] and plasma HSP70 were all collected during their first day exposure at 65, 71, 77, and 83 THI. Behavioral responses ? meal intake (MI), meal break (MB), standing, lying down, drinking, urination, and defecation ? were recorded and counted for frequency and duration at three different periods of the day (08:00?15:00h, 15:01?23:00h, and 23:01?07:59h) using internet protocol cameras. Results showed that RR and plasma HSP70 concentration obtained significant differences at 83 and 71 THI, respectively. Frequency and duration of meal intake and meal break decreased, consistent with the reduction in voluntary feed intake (P<0.05). Among the responses, meal intake duration is the most visible heat stress response that significantly occurred at 77 THI (27 °C), showing meal intake duration reduced by 556 s i.e., 25% of 2212 s (37 min) for the seven-hour period after feed is offered.
