SOUZA, Bonifácio Benicio de et al. Fisiological responses of the caprines from different genetic groups in the semi-arid of Paraíba. Ciênc. agrotec. [online]. 2008, vol.32, n.1, pp. 314-320. ISSN 1981-1829. http://dx.doi.org/10.1590/S1413-70542008000100045.
This experiment was realized in Pendencia's experimental station of EMEPA-PB in Soledade- PB city. It aimed to avaliate the fisiological and hematological parameters of caprines from diferent genetic groups in the semi-arid conditions. Thirty males weithing about 25,17 kg were used, being six animals from each genetic group: ½ Boer + ½ SRD (BO), ½ Anglo-Nubiana + ½ SRD (AN), ½ Savana + ½ SRD (SA), ½ Kalarari + ½ SRD (KA) e ½ Moxotó + ½ SRD (MO). It was verified significative effect (P<0,05) among the genetic groups for breathing frequency and hematocrit. The BO presented breathing frequency more elevated (P<0,05) than the AN and MO; and its hematocrit was less elevated (P<0,05) than the MO. The period affects sifgnificatively (P<0,05) the rectal temperature and breathing frequency, being the superior averages in the afternoon period. For the other parameters there were not significative differences among the genetic groups studied. Besides this, it can be concluded that the studied animals are adaptaded to the semi-arid climatic conditions.
