The giant anteater (Myrmecophaga tridactyla), wild mammal belonging to the superorder of Xenarthras, who originally inhabited Central and South America. It is currently classified as a vulnerable species, primarily due to deforestation, fires and running over accidents. The absence of reference values for laboratory tests increases the difficulty to assess these animals, especially due to the raising number of attendances in veterinary care institutions. Given the importance of such data, the aim of this study was to establish hematological, biochemical and electrophoretic parameters for captive giant anteaters as well to know which are the effects of storage conditions in hematologic samples with two different concentrations of anticoagulants. Therefore, we used 12 clinically healthy captive animals. The samples were collected from the jugular vein into appropriate blood tubes. The blood analysis was carried out immediately after colletion and in others two different times to check the storage effects (M0 - immediate analysis, M2 - 24 hours after collection, M3 - 48 hours post-collection). Biochemical analysis was performed a week after the harvest. Electrophoresis was carried out in agarose gel support. The mean and standard deviation of haematological variables of samples processed soon after harvest were: RBC (2.07 x 106/uL ± 0.40); packed cell volume (38.08 % ± 5.93); hemoglobin (11.33 g/dL ± 2.15); VCM (186.52 fL ± 21.72); MCHC (29.68 g/dL ± 2.56); MCH (55.08 pcg ± 5.94); total leukocytes (8142/uL ± 2,441); neutrophils (5913/uL ± 2168); lymphocytes (1460/uL ± 740); eosinophils (522/uL ± 385); monocytes (247/uL ± 176); platelets (123.458/uL ± 31.362) and total plasma proteins (6.23 g/dL ± 0.49). The mean and standard deviation corresponding to biochemical analysis was: albumin (3.29 g/dL ± 0.33); ALT (15.49 IU/L ± 7.98); amylase (1037.92 IU/L ± 149.04); AST (21.12 IU/L ± 7.50); total cholesterol (62.79 mg/dL ± 20.08); HDL cholesterol (14.73 mg/dL ± 4.98); LDL cholesterol (26.60 mg/dL ± 11.05); VLDL cholesterol (2.14 mg/dL ± 1.06); CK (111.61 IU/L ± 70.16); creatinine (1.05 mg/dL ± 0.37); iron (194.64 µg/dL ± 81.17); GGT (65.18 IU/L ± 54.57); glucose (103.71 mg/dL ± 29.63); globulins (2.76 g/dl ± 0.36); lipase (28.80 IU/L ± 5.11); PST (6.05 g/dL ± 0.56); triglycerides (10.71 mg/dL ± 5.29); urea (53.46 mg/dL ± 18.28). The results of the electrophoresis led to six protein bands which are classified as albumin (2.60 g/dL ± 0.33), alpha-1 (0.33 g/dL ± 0.07), alpha-2 (0, 50 g/dL ± 0.17), beta 1 (0.62 g/dL ± 0.17), beta 2 (1.50 g/dL ± 0.25) and gamma (1.88 g/dL ± 0.30). Therefore, we conclude that there are physiological changes in hematological and biochemical parameters of giant anteaters from different biomes. In these animals the electrophoretic pattern of the technique in agarose gel are six protein bands and the percentage of albumin is greater than the other fractions. This suggests that extrinsic factors such as climate, nutrition and management can affect these variables. Therefore, the results presented in this work can be used as laboratory parameters of healthiness in cerrado captive giant anteaters.
