The present experiment was carried out in the Experimental Station of Dispute, belonging to the State Company of Agricultural Research of Paraiba S.A. (EMEPA), located in the municipal district of Soledade -PB, in Curimatau Westerner small area, Semi-arid of Paraiba. One aimed with this, to accomplish an hematological evaluation of exotic and native goats servants in the semi-arid Paraiba. 40 females of the breed Boer, Savanna, Anglo-Nubiana and Moxoto, were used being, 10 of each breed, with medium age of five months, alloted in completely radomized design with 10 repetitions, grown in semi-intensive system. Environmental variables were registered in the shadow and sun at 9:00 and 15:00 o’clock with the aid of thermometers of maxim and low temperatures, dry bulb and humid bulb and black globe one. For the accomplishment of the hematimetria and leucometria, samples of 5 mL of blood of each animal were collected in vacuous tubes with anticoagulant. The variance analysis revealed breed effect for these hematological parameters: erythrocyte, hematocrit and hemoglobin. For the erythrocytes number there was significant difference among the breeds Savana, Anglo-Nubiana and Moxoto, but the Boer breed didn’t differ in relation to the breeds Savana and Anglo-Nubiana. There was significant effect for the variable leukocyte that presented the breeds Savana e Moxoto differing from the breeds Boer e Anglo-Nubiana. Although factors with breed and atmosphere influence on the hematological parameters, all of the breed presented averages inside the normal limits for the species, demonstrating to be well adapted to the climatic conditions of the semi-arid.
