Abstract

Alimentary habits of free-living Psittaciformes vary significantly among different species. Amazona pretrei is under risk of extinction and has very specific free-living dietary habits, which are based on Parana pine seeds. Hemosiderosis is a pathologic process characterized by intracellular accumulation of iron without other evident lesions. It is associated with increased prevalence of infections, neoplasms, and hepatopathies. The purpose of this study was to quantify hepatic hemosiderin deposits in captive A. pretrei and verify their association with nutritional parameters. Liver samples were processed for histopathology and stained with Prussian blue. The sections were analyzed by computerized morphometry to quantify the hepatic hemosiderin deposits. The hepatic hemosiderosis rates showed positive correlation with age and time in captivity. These results suggest that the menus and commercial rations for Psittacidae must be carefully revised. (AU)
