“…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.…”

“…IRT can detect the naturally emitted infrared radiation from an object, which is a measure of its surface temperature (ST), providing a representation of it as a heat map [27,28]. This technique is based on using the change in peripheral blood flow to assess variations in the animal's surface temperature [29]. Changes in core body temperature and skin temperature can be used as an indicator of thermal comfort and welfare [30].…”

“…Changes in core body temperature and skin temperature can be used as an indicator of thermal comfort and welfare [30]. Body temperature is regulated by the thermoregulatory center in the hypothalamus, and it is the result of cellular metabolism, the consequent production of heat and the control of heat dissipation through the body [29]. IRT methods have been attempted across different anatomical areas in different species [19,[31][32][33].…”

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.

“…This was similar to several reports [18][19][20] . Giannetto et al 21 and Piccione et al 22 , on the other hand, reported a higher temperature. The disparity could be accounted for by the fact that rectal thermometers were inserted 15 cm deep in these studies.…”

Background and Objective: Clinical examination and other diagnostic procedures, including enzymatic and hormonal assays, are important in equine medicine for disease diagnosis, assessing the extent of damage and monitoring the response to therapy. The study sought to establish the baseline data for some clinical, enzymatic and hormonal parameters and compare them between different ages, breeds and sexes. Materials and Methods: A total of 40 apparently healthy polo horses were sampled in Ibadan, Oyo State. Clinical parameters were recorded, blood was drawn through the jugular vein and serum was analysed for enzyme and hormone profiles. The student's t-test was used to compare these parameters and significance was taken at p = 0.05. Results: The results revealed more crossbred, female and adult horses in Ibadan, Nigeria. Significantly higher respiratory rate in crossbred horses compared to Sudanese breeds with (31.20±5.93) and (27.20±2.70) was observed, respectively. The respiratory rate was also significantly higher in young horses (34.00±8.49) compared to adult horse sand the adult (27.56±3.03). The values of prolactin, progesterone and oestrogen were significantly higher in female horses compared to males. Conclusion: There was a higher population of crossbred, female and adult horses in Ibadan. There were variations in the clinical, enzyme and hormonal values among different ages, sexes and breeds of horses, especially the enzymatic parameters, which seem to be proportionally increasing with the increase in the age of horses in Ibadan, Nigeria.

“…The relationship between stress and the metabolic system has been well documented in mammals using various invasive methods, such as blood sampling, the measurement of cortisol in saliva, thermal microchips, tympanic infrared recording and body temperature measurements [ 4 ]. Body temperature is considered an important indicator of welfare in animals as well as in humans, and has been used to monitor clinical status in assessments of fever, stress or infectious animal disease [ 5 , 6 ].…”

The aim of the present study was to investigate the response to physical exercise of some ocular physiological variables (ocular temperature and intraocular pressure) in horses performing a jumping course in the morning (a.m.) or in the afternoon hours (p.m.), before and after the exercise, in correlation with the rectal temperature. Data collection was carried out on 14 clinical healthy Italian saddle horses. All horses were trained from 9:00 to 10:00 a.m. and from 19:00 to 20:00 p.m. according to a specific training program. Ocular temperature (OT), rectal temperature (RT) and intraocular pressure (IOP) were determined. Statistical analysis showed no differences between the results for the left and the right eyes. The application of two-way repeated-measures analysis of variance (ANOVA) showed a statistically significant effect of time (before vs. after) on IOP (p = 0.0001). RT and OT were statistically influenced by time of day and by experimental conditions (a.m. vs. p.m.) (p = 0.0001). Bland–Altman (B-A) testing showed an agreement between the values of RT and OT. Our results showed a correlation between increased body temperatures and IOP variations during exercise, so they can probably be considered indicators of athletic horses’ physical fitness during exercise.
