Resumo: | This study evaluated the adaptive capacity and variations in physiological parameters of four male goats originate from a temperate region (Alpine breed) in a tropical climate over twelve months. The ambient temperature, relative humidity, and temperature via a black globe thermometer were evaluated to calculate the black globe temperature and humidity index; they were collected five times during the day, three times during the week, and during the four annual seasons. Every fortnight throughout the experimental period, respiratory and heart rates as well as rectal and surface temperatures of the animals were measured in the morning, and blood samples were acquired for hormonal levels (cortisol, T3, and T4) and complete blood count. There was a difference between the mean values of surface temperature, respiratory rate, hormones, and some hematological parameters (total protein and monocytes) between the seasons (P<0.05). However, no differences were observed in cases of heat stress, based on the fact that physiological parameters were within normal and expected limits for goats. Thus, it is concluded that the male goats of the Alpine breed, when reared intensively, maintain homeothermia and are greatly adaptable to the conditions of the tropical climate. |

Se evaluó la temperatura ambiente, la humedad relativa y la temperatura utilizando un termómetro de globo negro para calcular la temperatura del globo negro y el índice de humedad; se recolectaron cinco veces al día, tres veces a la semana y durante las cuatro estaciones anuales. Cada quince días durante el período experimental, se midió la frecuencia respiratoria y cardíaca, así como la temperatura rectal y superficial de los animales por la mañana, y se tomaron muestras de sangre para niveles hormonales (cortisol, T3 y T4) y hemograma completo. Hubo una diferencia entre los valores medios de temperatura superficial, frecuencia respiratoria, hormonas y algunos parámetros hematológicos (proteína total y monocitos) entre temporadas (P <0.05). Sin embargo, no se observaron diferencias en los casos de estrés por calor, debido a que los parámetros fisiológicos se encuentran dentro de los límites normales y esperados para las cabras. Así, se concluye que los machos cabríos de la raza alpina, cuando se crían de forma intensiva, mantienen la homeotermia y son bastante adaptables a las condiciones del clima tropical.Este estudo avaliou a capacidade adaptativa e as variações nos parâmetros fisiológicos de quatro caprinos machos originários de uma região temperada (raça Alpina) em um clima tropical ao longo de doze meses.
