Some Physical, Morphological, and Mechanical Characteristics of Turkey (Meleagris gallopavo) Eggs
Physical, morphological and mechanical characteristics of eggs play an important role in the processes of embryo development and hatching. Some physical, morphological and mechanical characteristics of turkey (Meleagris gallopavo) eggs (breed Zagorje turkey) collected during two laying cycles from same turkey hens were determined in this study. The average values of their length, width, geometric mean diameter, weight, surface area, volume, sphericity, shell thickness and shell density were found to be 66.61 mm, 46.84 mm, 52.66 mm, 77.74 g, 8712.42 mm2, 76553.49 mm3, 79.31%, 0.354 mm and 3.13 g cm-3, respectively. Eggs collected during second laying cycle were in average bigger and heavier in comparison to eggs collected during first cycle. The average albumen, yolk and shell percentage of the eggs collected during two laying cycles were 58.11%, 29.50% and 12.39%, respectively. The highest rupture force was obtained when the eggs were loaded along the X-front axis and the least rupture force was required along the Z-axis. The average rupture force, absorbed energy and firmness in loading along the X-front axis were found to be 73.80 N, 9.75 N mm and 280.30 N mm- 1, respectively.
