Resumo: Thermally stressful environments may cause physiological and metabolic changes in farm animals, among these, a higher methane production by ruminants. In this context, the main thermoregulatory mechanism in homeothermic animals is an increase in surface temperature, although other physiological parameters such as heart and respiratory rates are also indicative of environmental heat stress (Hahn, 1985; Bouzida et al., 2009). Infrared thermography, a technique that detects thermal radiation emitted by an object, is a non-invasive alternative to evaluate body temperature of free ranging animals. Goal of this work was to correlate temperatures obtained by thermal imaging with physiological responses from grazing cattle in Central Brazil.
