Abstract

the newborn puppy's thermoregulating capacity is deficient, and many of the physiological processes for survival depend on this capacity. Severe modifications in body temperature can lead to hypothermia in a few hours. Hence, the first 24 to 72 h of life correspond to the highest risk time, in which the newborn can course with moderate to severe hypothermia because the shivering reflexes and vasoconstriction mechanisms are not yet developed in the newborn of this species. Temperature stabilization is reached up to the 18th day of age. However, the colostrum's adequate consumption could provide a high energy supply, contributing to a fast recovery of temperature and, consequently, to a high survival rate. This review aims to analyze the factors that affect thermoregulation of the newborn puppy, the physiological and behavioral responses, as well as to discuss the influence of the colostrum as an energy source and production of heat to face hypothermia, aside from discussing recent scientific findings of infrared thermography (IRT) used to assess the thermal response of the newborn puppy to cope with hypothermia.

新生幼犬的热稳态:行为和生理反应

新生幼犬的体温调节能力不足，许多生存的生理过程依赖于这种能力。体温的严重变化会在几小时内导致体温过低。因此，在出生后的24 - 72小时是最高的危险期，在此期间新生儿可能出现中度至重度的体温过低，因为该物种新生儿的寒战反射和血管收缩机制尚未发育成熟。温度稳定持续到18日龄。然而，初乳的充分消耗可以提供高能量供应，有助于快速恢复温度，从而提高存活率。本文旨在分析影响初生幼犬体温调节的因素、生理和行为反应，并讨论初乳作为能量来源和产热对低温的影响，以及红外热像仪(IRT)用于评估初生幼犬应对低温的热反应的最新科学发现。

期刊介绍： The Journal of Animal Behaviour and Biometeorology (ISSN 2318-1265) is the official journal of the Center for Applied Animal Biometeorology (Brazil) currently published by Malque Publishing. Our journal is published quarterly, where the published articles are inserted into areas of animal behaviour, animal biometeorology, animal welfare, and ambience: farm animals (mammals, birds, fish, and bees), wildlife (mammals, birds, fish, reptiles, and amphibians), pets, animals in zoos and invertebrate animals. The publication is exclusively digital and articles are freely available to the international community. Manuscript submission implies that the data are unpublished and have not been submitted for publication in other journals. JABB publishes original articles in the form of Original Articles, Short Communications, and Reviews. Original Articles arising from research work should be well grounded in theory and execution should follow the scientific methodology and justification for its objectives; Short Communications should provide sufficient results for a publication in accordance with the Research Article; Reviews should involve the relevant scientific literature on the subject. JABB publishes articles in English only. All articles should be written strictly adopting all the rules of spelling and grammar.
