SUMMARY:

Climate change has a direct impact on the agricultural sector, which depends on these conditions to benefit its production. Cattle raised in Brazil, mostly in the Amazon, face high air temperatures, relative humidity and levels of solar radiation, reducing their zootechnical performance by reducing productive and reproductive indices. Different environmental and animal monitoring technologies have been used to overcome the constant challenge of heat stress in order to achieve superior livestock indices. Their use makes it possible to assess the environmental effects on animal production and help make decisions on herd management. To this end, the physiological parameters of young buffaloes raised in the Eastern Amazon will be evaluated throughout the day, using infrared thermography, and the thermal comfort indices will be correlated. The experiment will be carried out at the Federal Rural University of Amazonia - UFRA. Eighteen buffaloes (n=18) will be evaluated daily (morning: 6:00, 8:00, 10:00; afternoon: 12:00, 14:00, 16:00; evening: 18:00, 20:00, 22:00, 24:00): 18h00, 20h00, 22h00, 24h00) and the parameters assessed will be heart rate (HR), respiratory rate (RR), rectal temperature (RT) and the surface temperature thermograms of the eye socket (ORB), right flank (FLd), left flank (FLe) and nostrils (N). The climatological data will be monitored continuously, and the temperature and humidity index (ITU) and the Benezra comfort index (BCI) will be calculated.
