Study on physical properties of exotic and indigenous breed eggs

The present investigation was aimed to evaluate the physical properties of exotic and indigenous breed eggs. The collected eggs were analyzed for external and internal qualities. A significant difference (tcal>ttab) was recorded in quality parameters like weight (55.82 and 43.66 g), surface area (67.35 and 57.29 cm2 ), volume (50.96 and 39.86 cm3 ), albumen width (6.43 and 5.89 mm), albumen height (7.56 and 5.32 mm), yolk height (16.55 and 14.76 mm), albumen weight (34.17 and 24.46 g), yolk weight (15.64 and 13.95 g), albumen ratio (61.23 and 56.02), yolk diameter (4.29 and 3.84 mm) and yolk: albumen ratio (45.78 and 57.14)of exotic and indigenous breed eggs. It was observed that exotic breed eggs had a superior external and internal quality features when compared with indigenous breed eggs. However, the quality traits such as length, width, shape index, shell weight, shell thickness, shell ratio, albumen length, yolk length, yolk width, albumen index, yolk index, yolk ratio and Haugh unit have no much variation comparatively. Hence, on overall basis, the present study concludes that exotic breed eggs are considered for commercial usage. | Study on physical properties of exotic and indigenous breed eggs
