This study was carried out in the city of Nhamundá - Amazonas, between the communities of Laguinho, Aminarú - Açú, Urucuri and Paranã do Aduacá, on the João Batista farm during the dry season. The objective of this study was to show the drought conditions and their impact on logistics within the municipality of Nhamundá, characterize the environmental conditions, thermoregulation and productive parameters of Murrah breed buffaloes managed in an extensive system in the municipality of Nhamundá, Amazonas. Seven buffaloes at the end of lactation were used. For the data collected in this study, an infrared thermographic camera, model Uti260B, was used, where infrared photos of the buffaloes were recorded during milking. For the physiological parameters, the environmental thermal stress meter, model IBUTG AK887, was used to measure the levels of UTI and ITGU of the environment at the time of milking, and also to evaluate the physiological parameters upper critical temperature (UTC), respiratory rate (RR) and infrared thermography (ITV) of Murrah buffaloes managed in an extensive system, in the different ITGU conditions, these devices were used to evaluate the thermal comfort conditions of the environment. For the analysis of milk production and composition for the fat and protein contents of Murrah buffaloes managed in ambient conditions characterized by this study; aliquots of 60 ml of milk were collected, which were carefully removed from the bucket and added to sterile, preservative-free polypropylene bottles. After collecting the milk, it was sent to the municipality of Parintins, where it was analyzed at the Biotechnology Laboratory, located at the Institute of Social Sciences, Education and Animal Science (ICSEZ) of the Federal University of Amazonas (UFAM), where the milk composition analyses were performed. In the Biotechnology Laboratory, the milk was analyzed using the ®LACTOSCAN Ultrasonic Milk Analyzer S PFP.
