The experiment was carried with the objective of evaluating the adaptability of the breeds goats to Semiárid through physiologic parameters: rectal temperature, respiratory frequency and surface temperature and the structures of the tegument: perspiration glands, fat of glands and hair follicles. 40 female were used goat, of the breeds Anglo-Nubiana, Savana, Boer and Moxotó, being 10 animals of each breed, with medium age of five months. For the physiologic answers, he animals were allocated into a completely randomized design entirely in portions subdivided in the time, with the main treatments constituted by the breeds and the secondary ones by the shifts. For the study steorologic of the tegument was used in a completely randomized design entirely with four treatments and three repetitions. There was in significant teraction (P<0.05) between breed and shift, for the rectal and surface temperature. The breed Savanna it presented larger medium (P<0.05) for respiratory frequency and the Anglo-Nubiana to medium smallest (P<0.05). There was significant difference (P<0.05) regarding the number of hair follicles for breed Anglo-Nubiana that presented the smallest number, differing significantly (P<0.05) of the breeds Savanna and Moxotó that presented the largest averages, however these didn't differ (P>0.05) of the Boer breed. The breed Anglo-Nubiana it presented larger number of glands perspiration (P<0.05) and the breed Savanna presented the largest average of fat of glands (P<0.05). The studied breeds demonstrated to be physiological well adapted and with characteristics of the favorable tegument to the climatic conditions of semiarid.
