Valores de referência de hematologia e bioquímica sérica de papagaios-verdadeiros (Amazona aestiva) mantidos em cativeiro

Abstract

The birds have always aroused great interest in the human being, with emphasis on the copies in the Psittacidae family, diversity, beauty and abilities as a blue-fronted Amazon (Amazona aestiva) for being considered animal sociable, intelligent and able to imitate the human voice and reproduce words. These species considered silvestres are currently kept in captivity, as pets or for rehabilitation due to disorders caused by trafficking in wild animals. On this condition in which these wild birds are living in captivity, even with some specific literature about Psittacidae, the need arises for new forms of clinical and laboratory analysis to assist the veterinarian's job. The values and benchmarks used for parrots-true when in free life are often not compatible with the conditions of captivity. The determination of serum biochemical parameters helps in the diagnosis of metabolic diseases, in the definition of the nutritional profile of a population and allows for a more directed clinical evaluation at the individual. The present study aimed to determine the reference values for serum biochemistry of True parrots (Amazona aestiva) maintained in captivity in Minas Gerais. For this sample were collected 42 True parrots, clinically healthy, maintained in a captivity in Belo Horizonte, Minas Gerais. Was assessed quantitatively the hematology of the birds to identify general health conditions the biochemical profile of the same from the analysis of uric acid, creatinine, aspartate aminotransferase (AST), alanine aninotransferase (ALT), glucose, triglycerides, cholesterol, total protein, albumin, plasma calcium, phosphorus and urea. On Hematology was found induced leukopenia by use of isoflurano on chemical restraint of the birds and the use of Natt-Herrick in the dilution for differential leukocyte count which can lead to difficulty in differentiating between thrombocytes and small lymphocytes and thus generate leukopenia by artifact. Averages obtained for the biochemical parameters evaluated presented average values within the expected to true parrots kept in captivity except the variables ALT, averaging well above expected, calcium and albumin averaging below.
