Résumé:
The present work had the aim to determine thermal means at installation to ovines
and analyse physiological parameters and way of life degree of 4 genetic groups, in the dry region
of Paraiba. It had been used 40 animals, 10 per genetic group: Cariri, Morada Nova, Barriga Negra
and Cara Curta ,all of them were female ,kept in 4 places by chance .Data were air temperature
(TA), air relative humidity (UR), wind speed (Vv), dark block temperature (Tgn), humidity and
dark block temperature (ITGU), radiation thermal support (CTR). Physiological data were
respiratory frequency ( FR), heart frequency (FC), bottom temperature (TR) and superficial
temperature (TS), evaluated for 9 and 15 h. Way of life degree was carried out by Baccari Junior
Test. Data evaluation was carried out in randomized sketching in 4x2, being 4 genetic groups and
two periods .Environmental means ,in the afternoon, were upper to the morning ones and had its
values, with exception to UR and Vv, increased to the normal tax. TR, FR, FC and TS in the
afternoon were higher than in the morning, but TR normally and FR and FC upper to the normal.
ITC did not show significance difference among genetic groups and showed that the animals, with
higher FR and FC showed high capacity to the region.
