Abstract
Five calves were transported for 8 hours, traveling 520 km. We examined fluctuations in the body surface temperature of the calves during transportation using infrared thermography (IRT). The body surface temperature of the calves did not correlate with blood cortisol concentrations (r=-0.209 to 0.007). On the other hand, the body surface temperature of the calves did correlate well with the environmental temperature in the livestock truck (r=0.880 to 0.904). Changes in the body surface temperature of the calves were more affected by environmental temperature than by transport stress during transportation.
