Email: email@example.com The aim this work was to establish reference values of the hemogram of Sindi cattle raised in Paraiba backwood and evaluate the influence of same age, on blood samples we collected from 60 clinically healthy animals, being 30 females and 30 males, with the following age groups: Group I: 6 - 24 months, Group II: 24 - 48 months and Group III: up to 48 months. The experiment was conducted at the Center for Research and Development for the Semiarid Tropics (NUPEÁRIDO) and the Veterinary Clinical Pathology Laboratory of the Health Center and Rural Technology (CSTR), Universidade Federal de Campina Grande (UFCG), Campus de Patos-PB. Blood samples were placed in tubes containing EDTA (tetracético-ethylenediamine-di-sodium) as an anticoagulant were performed the following tests: counting the number of red blood cells, packed cell volume (PCV), Hemoglobin (Hb) content, calculations of absolute Erythrocyte count (RBC), Mean corpuscular volume (MCV) and Mean corpuscular hemoglobin concentration (CHGH). Held global count and differential leukocyte such as segmented neutrophils, eosinophils, lymphocytes and monocytes. Reference values for erythrocyte count (RBC), hematocrit (PCV), hemoglobin (Hb), MCV and CHGH were, respectively, (6375 to 13,400 X106 / MM3 ), (32 – 50 %), (9 - 15 G/DL) (37 – 60 µ3), (23 to 33 µµG). And for the WBC were obtained the following results: WBC (5270 to 17,170 UL), segmented neutrophils (from 1360 to 5780 UL) Eosinophils (240 to 2525 UL), lymphocytes (2330 to 11,470 UL), monocytes (72 – 116 UL). With the results showed differences in hematological values were important to establish reference values for breed.
