The present study had as objective evaluates the physiologic behavior of different genetic groups of sheep created in the semi-arid paraibano in the dry and rainy times. Forty sheep were used, eight of each genetic group, distributed entirely in a randomized design. There was shift effect, for all the environmental variables and studied physiologic parameters. There were significant interactions of the factors genotypes, time and hour for the parameters, rectal temperature and breathing frequency. With relationship to the Index of tolerance to the heat (ITC) significant effect of the studied factors was not verified. With these results it can be ended that the races Santa Inês, Cariri and the products, resultants of crossings of the animals 1/2Dorper and 1/2Damara with sheep without defined race (SRD) they resemble each other in the adaptation aspect to the conditions of the semi-arid.
