“…Rectal thermometry is commonly used in the evaluation of a horse's body temperature (Collins et al, 2016; Hall et al, 2019; Ramey et al, 2011). However, the process of obtaining rectal temperature is both time‐consuming and laborious, often putting handlers in danger of bites and kicks, in addition to being a stressful procedure for horses (Kang et al, 2020; Ramey et al, 2011).…”

SummaryAmidst discourse surrounding the racing industry's social licence to operate, the welfare of racehorses and jockeys is often at the forefront of discussions. Specifically, catastrophic events and the sudden death of horses on race days tend to capture media attention and often place the racing industry under public scrutiny. While such occurrences are not frequent, they have negative ramifications on the welfare of both racehorses and jockeys. The development and application of advanced monitoring technology could provide greater insight into the physiological precursors that immediately precede sudden death on race days and enable retrospective analyses of catastrophic events that take place. Most importantly, the application of such technology could ultimately aid racetrack personnel in identifying and intervening with horses at increased risk of catastrophic events, right up until the start of a race. This would inevitably improve the safety and welfare of horses and jockeys. Thus, the current review details key cardiovascular, respiratory and thermometry biometrics for racehorses and examines the currently available commercial devices with potential applications during racing. This review also highlights the importance of gathering biometric data for retrospective analyses of catastrophic events and their implications on the welfare of racehorses and jockeys.

“…Its simplicity and ease of use make it an interesting alternative for equine temperature assessment. Previous studies [ 9 , 10 ] have used infrared spectroscopy (IRT) to measure body temperature in various parts of the equines’ bodies, focusing primarily on the head and body axis to determine the most accurate infrared temperature to express changes in the core body temperature. The reliability and non-reliability of IRT in the body trunk have been demonstrated [ 9 , 10 ].…”

On the other hand, the head is preferable, especially the eye region, because it is abundant in blood supply, and the skin is thinner than other parts of the body.…”

Background and Aim: Body temperature is a vital sign that determines physical status. Infrared thermography (IRT) is more frequently used for assessing horses’ temperature because of its ease of use and less contact with the horses, making it a safer measurement method. However, the accuracy of IRT remains unclear; therefore, this study aimed to assess the potential use of IRT as an alternative method for measuring horse body temperature. Materials and Methods: Temperatures were measured in 14 horses. A digital thermometer was used to collect rectal temperature (RT), whereas a thermographic camera was used for IRT at three different positions to obtain the center of body temperature (CBT), head temperature (HT), and eye temperature (ET). The protocol was performed over 30 days, repeated thrice daily: morning (6:00–8:00), afternoon (14:00–15:00), and evening (17:00–19:00). Environmental factors, including humidity, ambient temperature, wind flow, and light intensity, were recorded indirectly according to the time of day and cooling device use. Results: Mean RT, CBT, HT, and ET were 37.33°C, 34.08°C, 35.02°C, and 35.14°C, respectively. Center of body temperature was lower than RT by an average of 3.24°C (95% confidence interval [CI], 5.4°C–1.09°C). HT was lower than RT by an average of 2.3°C (95% CI, 4.33–0.28). The eye position showed the least difference between RT and infrared temperature, with an average of 2°C (95% CI, 0.7–3.92). However, there was no significant correlation between RT and infrared temperature at any position. Spray and vaporizer use significantly affected IRT and time of day (p = 0.05). Conclusion: Although IRT has advantages in terms of non-invasiveness and reduced stress on horses, its accuracy and reliability may be compromised by environmental variables, which interfere with infrared measurement. Future research should specifically focus on investigating environmental factors. Keywords: body temperature, digital thermometer, horse, infrared thermography, radiation.
