AN INGLUVIOLITH IN A BUDGERIGAR (MELOPSIT TACUS-UNDULATUS)

An eight year old budgerigar was presented in a small animal practice with apathy, difficulty in swallowing and the escape of frothy liquid out of the beak. An ingluviolith was diagnosed, removed by surgery and then analysed. The data of the chemical composition indicate a concre ment consisting of uric acid (30.6 % N) mainly. Results of further che mical analyses were contradictory to the presence of struvite or miner al stones. In the light of published case reports the pathogenesis of ingluvioliths is discussed briefly.
