“…It has been suggested that the eye is not affected by ambient temperature and has been considered a useful indicator of core body temperature [ 35 ], which can be used for detecting temperament [ 36 ], pain [ 37 ], or response to stress in cattle [ 38 ]. Studies with several cattle breeds reported that the eye had high correlations with RT [ 9 , 26 ].…”

This study evaluated the influence of environmental temperature on thermoregulation, hormonal, and hematological characteristics in Caracu cattle. Blood samples, hair length, coat and muzzle colors, rectal (RT), and surface temperatures were collected from 48 males and 43 females before (morning) and after sun exposure for eight hours (afternoon). Infrared thermography (IRT) was used to identify superficial temperature that exhibits a high correlation with RT. Hematological parameters, hormone concentrations, RT, and the superficial temperature obtained by IRT that exhibited the highest correlation with RT were evaluated by variance analysis. Regarding IRT, the lower left side of the body (LS) showed the highest correlation with the RT. Interaction between period and sex was observed for LS, cortisol, and eosinophils. Cortisone, progesterone, and RT were influenced by period and sex. Neutrophils and segmented neutrophils were influenced by the period, which showed the highest concentrations after sun exposure. Platelets, leukocytes, lymphocytes, and monocytes were influenced by sex. Heat stress changes several physiological characteristics where males and females exhibited differences in their responses to heat stress. Furthermore, most characteristics evaluated remained within the regular values observed for taurine Creole breeds, showing that Caracu is adapted to tropical climates.

“…Other studies have tried to assess a stress-induced thermal response-personality relationship under controlled laboratory conditions or on domestic animals. Thermal temperature imagery of the eye and beef cattle temperament were not related (Chen et al 2021). Conversely, IRT applied on domestic cat's eyes and tail temperatures of mound-building mice (Mus spicilegus) yielded significant relationships: individuals that were bold and/or fast explorers had a higher core temperature or lower peripheral temperature when exposed to stressful situations (Foster & Ijichi 2017;Duparcq et al 2019).…”

“…Much of the literature in this area is related to livestock and how stress affects meat quality (Travain & Valsecchi 2021). Chen et al (2021) used IRT to evaluate beef cattle personality by eye temperature as a proxy for body core temperature and the effect of SIH. They failed, however, to detect a strong relationship between thermal temperature imagery and temperament.…”

The study of the relationship between animal stress and personality for free‐ranging animals is limited and provides contrasting results. The perception of stressors by an individual may vary due to its personality, and certain personality traits may help individuals to better cope with them. Using non‐invasive infrared thermography (IRT), we investigated the link between physiological and behavioral components expressed during an acute stress event by free‐ranging Fremont's squirrels (Tamiasciurus fremonti). We expected that, during the acute stress event of being approached by the researcher, individuals that showed a fast pace‐of‐life syndrome (bolder, more active, and less social/more aggressive) based on an arena test would exhibit stronger sympathetic‐adrenal‐medullary system reactivity showing a more intense stress‐induced hyperthermia (high core body temperature and low peripheral temperature) than individuals with a slow pace of life (shy, less active, and more social). We successfully employed IRT technology to images of Fremont's squirrels with identification of the individuals’ body parts (eye, nose, ear, hind foot). However, we found no support for our hypothesis. Squirrels’ body surface temperatures told us more about a squirrel's external environment and less about the thermal state of the body in that environment following a stressful event. Further studies need to assess how to make IRT effective and efficient in the field and improve its performance in studying the relationships between physiology and personality in wildlife.

“…A large portion of these illnesses induce changes in blood flow dynamics, cause inflammation and resultantly change the localized thermal profile of the animal. Areas of interest for IRT-based observation are -the coronary band in feet; the plantar aspect of the pastern; posterior surface of the udder in cattle [6]; mammary gland; vulva; pelvis; thorax; left and right abdomen/flank; wither; [7,8] the medial posterior palpebral border of the lower eyelid and the lacrimal caruncle [9].…”

Infrared thermography (IRT) and its application for livestock state-of-health monitoring has been a focal point of many research works over the past 10 years. IRT is a powerful tool for detection and evaluation of localized inflammation sites. With most works centered around utilization of complex and expensive IR imaging devices - we investigated the prospect of developing a cost-effective automated monitoring stand with the application of simple IR micro-grid scanning end-devices.
