This study aimed to evaluate the physiological and reproductive parameters of Nelore cows under different microclimatic conditions. The experiment was performed in Central Brazil, which has a tropical climate, dry winter, and rainy summer. The experimental groups were divided into an area with shading (5.8 trees/ha; n = 42) and an area with little shading (0.4 trees/ha; n = 42). We assessed physiological parameters (heart rate, respiratory rate, rectal temperature, surface body temperature, and vaginal temperature), and reproductive parameters (estrus detection, conception rate, and rate of pregnancy loss). Rectal temperature (p = 0.002), surface body temperature on the flanks, forehead, and shoulder (p |
