ALVARADO, Mary Cruz et al. Hematological values in psittacine birds, ara and Amazona genus, captive in Venezuelan zoological parks. Rev. Cient. (Maracaibo) [online]. 2008, vol.18, n.6, pp.469-661. ISSN 0798-2259.

In order to determine hematological reference values, a total of 104 blood samples were obtained from captive birds of Ara and Amazona genera in different Venezuelan zoos. Red Blood Cell (RBC), Packed Cell Volume (PCV), Mean Corpuscular Volume (MCV), White Blood Cell (WBC) and leukocytes differential counts were measured using manual haematological methods. Absolute leukocytes values were calculated hematological parameters of Ara and Amazona genus respectively were RBC (3.02x10⁶µL and 2.33 x10⁶µL), PCV (49.6 and 50.03%), MCV (175.5 fL and 225.5 fL ), WBC (11804 cel x µL and 9752 c/uL) Heterophils (67.2 and 62.5%) , Band Heterophils (0.9 and 0.9%) Lymphocytes (28.2 and 31.6%), Eosinophils (2.9 and 1.6%), Monocytes (1.97 and 1.4%). These results coincide with the reference intervals documented in other countries for this genera. Only Eosinophils values were higher than reported values probably due to intestinal parasitic diseases during captivity.
