“…Machado et al [48] evaluated the pupil area, BT, and CORT concentrations in 360 piglets subjected to long-distance transport (75 km). The pupil area increased by 19.3%, along with a significant increase in CORT by 2.37 ng/mL and BT by 1.24 • C. Additionally, high positive correlations between pupil area, CORT, and BT were reported (r = 0.92, 0.90, and 0.82, respectively).…”
