Hematologic reference values of Vinaceous-breasted Amazon (Amazona vinacea)

Abstract

ABSTRACT Avian hematologic reference intervals are useful tools to evaluate body homeostasis and diagnose diseases. However, there are few species-specific reference intervals published. The present study reports Vinaceous-breasted Amazon ( Amazona vinacea ) hematologic reference values obtained during the health status evaluation of release candidates as part of this species reintroduction efforts at the Araucárias National Park. Parameters reported are erythrogram (erythrocytes, hemoglobin, packed cell volume, mean cell volume, mean corpuscular hemoglobin concentration and mean corpuscular hemoglobin), Red Cell Distribution Width (RDW), white cells total and differential (heterophiles, lymphocytes, basophils, eosinophils and monocytes), thrombocytes and total plasma protein. For the first time results on RDW and thrombocytes were described and a larger sample size were provided for all parameters analyzed. Intervals demonstrated in the present study showed significant differences from those considered normal in other parrot species and consequently have contributed to bring valuable information to base actions for the conservation of this endangered species of great biological value.
