“…One of the tools used to evaluate dermal surface temperature as an indicator of well-being in livestock is infrared thermography (IRT). Thus, various studies have exposed the possible uses and applications of IRT—for example, in the phenomena of hyperthermia associated with stress in lactating dairy cows during isolation challenges [ 73 ], diagnostic support of subclinical mastitis not only in cows but also camels ( Camelus dromedarius ) [ 74 , 75 ], and febrile processes due to diseases and in the evaluation of negative emotions such as fear and anxiety [ 9 , 76 ]. All these cases were evaluated indirectly by the vasomotor response associated with the increase in surface temperature.…”

Hyperthermia elicits several physiological and behavioral responses in livestock to restore thermal neutrality. Among these responses, vasodilation and sweating help to reduce core body temperature by increasing heat dissipation by radiation and evaporation. Thermoregulatory behaviors such as increasing standing time, reducing feed intake, shade-seeking, and limiting locomotor activity also increase heat loss. These mechanisms are elicited by the connection between peripheral thermoreceptors and cerebral centers, such as the preoptic area of the hypothalamus. Considering the importance of this thermoregulatory pathway, this review aims to discuss the hypothalamic control of hyperthermia in livestock, including the main physiological and behavioral changes that animals adopt to maintain their thermal stability.
