title: [The myocardial thickness in budgerigars (Melopsittacus undulatus) and Australian king parrots (Alisterus s. scapularis)].
abstract: Due to lack of reference values an objective assessment of myocardial dilatation and hypertrophy in cage and aviary birds so far is not possible. Therefore the thickness of the myocardium of the left and the right ventricle of the heart of 14 budgerigars (Melopsittacus undulatus) and 5 Alisterus parrots (Alisterus s. scapularis) of both sexes was examined according to a standard protocol to establish morphometric data and first reference values. In order to compare the results of birds of different sizes all data were set in relation to the size of the bird's body (length of the sternum). Results of different zones were compared by means of statistical methods within one species. Besides that a comparison between the two species was performed. Only minor significant differences could be noticed.
