“…Good management conditions during transport make it possible to maintain an acceptable level of welfare, e.g., choosing an optimal time of day for traveling in accordance with the daily fluctuations of physiological parameters such as body temperature and always encouraging proper ventilation. It would also be good practice to keep horses as close as possible to other horses in the same herd [47,48]. The present results show a positive correlation between ET, RT and cortisol concentration over distances of 100 km.…”

“…Environmental parameters recorded and the obtained THI were found to be within a 'no stress' area during both journeys. These values can be attributed to the species-specific thermoneutral zone, which is found to be between 10 and 24 • C in a horse where stress is minimal and performance optimal [29,47,48]. The present study showed a significant higher value of ET after the 100 km journey in each investigated eye region and higher values of RT after both journeys, indicating a physiological effect of the transport experience.…”

The aim of the present study was to investigate eye temperature modifications after road transport in athletic horses habituated to travel. Eight adult Italian saddle horses traveled 100 km and, two weeks later, 300 km. Eye temperature (ET), rectal temperature (RT) and serum cortisol concentration were assessed before (T1), after (T2) and 60 min (T3) after the road transport. ET was evaluated with infrared thermography (IRT) in three regions of interest: EL1 (medial canthus), EL2 (central cornea) and EL3 (lateral canthus). Two-way analysis of variance (ANOVA) for repeated measures showed statistically higher values at T2 and T3 for EL1 (p < 0.01), EL2 (p < 0.01) and EL3 (p < 0.01) following the 100 km journey. RT (p < 0.01) showed higher values at T2 and T3 after the 100 km journey and higher values at T2 (p < 0.01) following the 300 km journey. ET values were positively correlated with RT at T1, T2 and T3 following the 100 km journey and at T2 following the 300 km journey and positively correlated with serum cortisol concentration at T1, T2 and T3 following the 100 km journey and at T2 and T3 following the 300 km journey. Eye temperature monitoring with IRT allows quick and practical strategies to monitor an animal’s physiological state and welfare during daily activities.
