SUMMARY:

The hematological and biochemical evaluation reflects the health and productive status of the animals and may vary according to the environment and rearing system to which they are submitted. The objective of this study was to determine the hematological and biochemical profile of Lacaune sheep raised in the Zona da Mata of Pernambuco. Sixtyone healthy Lacaune sheep, aged between three and 24 months, raised in a semi-intensive system, in the municipality of Pombos, Pernambuco, were used. The animals were divided into four groups: G1 (N=32), aged from three to twelve months; G2 (N=29) between thirteen and 24 months; G3 (N=13) composed of males and G4 (N=48) composed of females. The study animals were selected after clinical, hematological and egg count examinations per gram, and only those with expected values for the species and with low parasite load were used. From the selected sheep, a blood and serum sample was collected in the morning for the determination of hematological and biochemical analyzes (total proteins, albumin, creatinine, urea, AST, ALT, GGT, alcaline phosphatase, serum calcium, phosphorus, magnesium and iron). When evaluating the results obtained for the hematological and biochemical tests, it was found that the mean values of Red Blood Cells (11.37±0.25x106/µL), Blood Volume (43.85±0.84%), Mean Corpuscular Hemoglobin (24.40±0.30%) and Platelets (479.93±35.51x10³/mm³) were significantly (p<0.05) higher in G1 animals, as well as Albumin (3.24± 0.05mg/dL), Gamma GT (68.15±2.45U/L), Alkaline Phosphatase (557.87±41.17U/L) and Iron (207.84±7.20μg/dL). The results of ALT (22.80±0.80U/L) and Monocytes (1.03±0.22%) were significantly (p<0.05) higher in G2 animals compared to G1 animals. There was no significant difference (p<0.05) in all parameters analyzed, when comparing the sexes. With this study, it was possible to determine the normality values of Lacaune sheep raised in Zona da Mata, Northeast, which will help in establishing the diagnosis, as well as determining prognosis and planning therapeutic options within the established age groups.
