Abstract
The investigations focused on the establishment of the main quality indexes for the eggs laid by undulated standard budgerigars "Melopsittacus undulatus". The assessments were run on 120 eggs, issued from three representative aviaries in Moldova, conventionally coded with L1, L2 and L3. They involved morphological, physical and chemical assays, run in accordance with the most used aviculture techniques. The achieved data revealed a good uniformity for most of the studied traits, as the lack of statistical significance of the differences found between groups proved it; however, significance occurred just for the eggs specific gravity. Quality indexes, established for the whole studied population presented various levels, as following: 2.51 g for the weight; 2.41 cm3 for volume; 79.89% for shape index; 0.95 for specific gravity;0.25 mm for shell thickness and 0.177 kgf/cm2 for shell breaking strength.
The results we achieved provide original data related to the quality of the eggs laid by standard type undulated parrot, contributing thus in making a larger picture of this species biology.
