Quality traits of goose eggs: 2. Effects of goose origin and storage time of eggs

Effects of origin and storage time on some interior and exterior egg properties in 1 year old Armutlu, Tatlicak, Baskuyu and INRA geese were evaluated. The mean values were 145.1, 148.5, 147.2 and 144.2 g for egg weight, 1.85, 2.00, 1.89 and 2.37% for egg weight loss, 19.4, 21.6, 20.0 and 18.7 g for shell weight, 13.7, 14.8, 13.8 and 13.3% for shell ratio, 0.54, 0.58, 0.55 and 0.55 mm for egg shell thickness, 67.1, 70.3, 66.7 and 68.0% for shape index, 72.9, 73.7, 74.1 and 77.0 g for albumen weight, 51.2, 50.6, 51.2 and 54.6% for albumen ratio, 50.1, 50.3, 50.4 and 45.1 g for yolk weight, 35.1, 34.6, 35.0 and 32.2% for yolk ratio, 0.06, 0.07, 0.07 and 0.06 min for egg shell membrane thickness for Armutlu, Tatlicak, Baskuyu and INRA geese, respectively. Mean values for Haugh unit, albumen index and yolk index of freshly broken eggs (without storage) were 76.9, 9.19% and 37.1%, respectively. Origin significantly affected egg weight loss, shell weight, shell thickness and shape index. Furthermore, effect of origin was significant on yolk weight, albumen weight and albumen index. But, it was not significant for shell membrane thickness, Haugh unit and yolk index. The egg weights of all origins were nearly identical. The egg weight loss increased with increasing storage time. Albumen weight, Haugh unit, albumen and yolk index values decreased with storage time.
