A Comparative Study of Physical Characteristics and Albumin Protein Content of Different Avian Eggs

Introduction: Eggs play a vital role in avian reproduction by providing a protective environment for embryonic development. The physical characteristics of avian eggs, including size, weight, shape, shell thickness, and yolk-to-albumin ratio, vary across species and are adapted to ecological and physiological requirements. Egg albumin is crucial in supplying nutrients and offering antimicrobial protection, making the study of albumin protein content across avian species significant for biological and nutritional sciences. Methodology: This study aimed to compare the physical characteristics and albumin protein content of eggs from four avian species: Broiler chicken (Gallus gallus domesticus), Domestic chicken (Gallus gallus), Domestic duck (Anas platyrhynchos domesticus), and Common quail (Coturnix coturnix). Eggs were collected from local sources and analyzed for whole egg weight, albumin and yolk weight, yolk color, albumin pH, and protein concentration. Results: The results indicated that Domestic Duck eggs had the highest weight (68.571.35 gm), while Common Quail eggs were the lightest (10.950.45 gm). The pH of albumin was highest in Duck eggs (8.660.07) and lowest in Gavran eggs (7.670.02). Yolk color varied from yellow in Broiler to deep orange in Duck eggs. Quail eggs showed the highest albumin protein concentration (2.990.20 mg/ml), making them nutritionally dense. Conclusion: These findings highlight species-specific differences influenced by genetic and environmental factors and offer insights into avian reproductive adaptations and the nutritional significance of eggs.
