La tThermorregulación en los mamíferos recién nacidos es un mecanismo esencial del sistema nervioso específico de la especie que ction in newborn mammals is an essential species-specific mechanism of the nervous system that contribuye a su supervivencia durante las primeras horas y días de vida. Cuando se expone al frío, que es untes to their survival during the first hours and days of their life. When exposed to cold weather, which is a risk factor de riesgo asociado con la associated with mortalidad en los recién nacidos, se activan vías como el eje hipotálamoty in neonates, pathways such as the hypothalamic-pituitario-suprarrenal y-adrenal axis (HPA) para lograr el control de la are activated to achieve temperatura, aumentando los nivelese control, increasing the circulantes deting levels of catecholaminas ye and cortisol.

This study aimed to discuss the mechanisms of thermoregulation in newborn domestic mammals, highlighting the differences between altricial and precocial species. The processes that employ brown adipocyte tissue, shivering, thermoregulatory behaviors, and dermal vasomotor control will be analyzed to understand the physiology and the importance of implementing techniques to promote thermoregulation and survival in the critical post-birth period of mammals. Also, infrared thermography as a helpful method to perform thermal measurements without animal interactions does not affect these parameters.
