ENDOCRINOLOGIC AND PATHOLOGICAL FINDINGS IN BIRDS WITH POLYOSTOTIC HYPEROSTOSIS

Polyostotic hyperostosis is a finding that is often seen on x-rays in companion birds. Hyperestrogenism might be a causative for polyostotic hyperostosis. The purpose of this study was to compare endocrinologic and pathologic findings in birds with polyostotic hyperostosis. Thirt y-five affected and three control birds were examined. Blood samples w ere taken for endocrinologic statement (estrone, estradiol, testostero ne and estronsulfate) and the values were compared with the pathologic findings. In the present study the comparison of endocrinologic and p athologic findings did not reveal any significant results supporting t he hypothesis that polyostotic hyperostosis was caused by hyperestroge nism.
