Thermoregulation, responsible for maintaining a stable core temperature during wide fluctuations in external and internal thermal environments, is an iconic homeostatic process. However, we suggest that despite its fundamental physiological significance, the potential for required cool housing temperatures and thermoregulatory mechanisms to influence the interpretation of experimental data is not sufficiently appreciated. Moreover, although it is generally assumed that the major thermoregulatory pathways are well understood, here we discuss new research that suggests otherwise and reveals the emergence of a new wave of exciting ideas for this "old" field of research.

The creation of any model is complex requiring vast amounts of data, typically gathered over a series of experiments. Specifically the temperature humidity index (THI) and heat load index (HLI) are used as management tools to implement mitigation strategies during hot climatic conditions. Exposure of the testes to hot climatic conditions has a negative impact on spermatogenesis in the bull, and other species.

Transient receptor potential (TRP) channels with temperature sensitivities (thermo-TRPs) are involved in various physiological processes. Thermo-TRPs that detect temperature changes in peripheral sensory neurons possess indispensable functions in thermosensation, eliciting defensive behavior against noxious temperatures and driving autonomic/behavioral thermoregulatory responses to maintain body temperature in mammals. Moreover, most thermo-TRPs are functionally expressed in cells and tissues where the temperature is maintained at a constant core body temperature.

As global temperatures rise due to climate change, the frequency and intensity of heatwaves are increasing, posing significant threats to human health, productivity, and well-being. Thermoregulation models are important tools for quantifying the risk of extreme heat, providing insights into physiological strain indicators such as core and skin temperatures, sweat rates, and thermal comfort levels. This study evaluated four thermoregulation models of varying complexity, differentiated by the geometry and underlying thermoregulatory mechanisms.

Physiological and hematological traits and productive performance of Spanish Majorera and Palmera goats reared on the Island of Tenerife-Spain were assessed. 50 adult, clinically healthy, multiparous female goats were studied for 18 months. The data were analyzed in a two (breeds) x four (season) factorial scheme.
