Egg weight, Haugh unit (HU), egg grade, albumen height, yolk color, eggshell thickness and eggshell breaking strength values are mean±SD (n=20) and weight loss values are mean±SD (n=10).
Egg grade based on HU: AA>72; 60≤A≤72; 31≤B≤59; and C≤30.
Means within a column with different uppercase letters are significantly different (p<0.05).
Means within a row with different lowercase letters are significantly different (p<0.05).
