This experiment was conducted on breeds of goats and woolless sheep in the tropical northeast Brazil to measure their body temperatures in the morning (at 7:00A.M.) and in the afternoon (at 2:00 P.M.) after exposure to direct solar radiation under simulated conditions of normal grazing. In general there were no marked differences between species of sheep and goats. Significant differences (P<0.05) were observed between breeds when body temperatures were averaged separately for morning and afternoon. The maximum rise in body temperature at 2:00 P.M. was observed in Canindé goats and Santa Inés sheep and relatively minor increases were observed in Bhuj and Anglo-Nubian goats and Morada Nova sheep; minor increases were considered as indices of better adaptability. The overall periodic variations at 2:00 P.M. in body temperatures were closely associated with the fluctuations in the afternoon environmental temperatures.
