The Relationship Between Eggshell Color and Egg Quality as well as Eggshell Ultrastructure

Through measuring eggshell color,egg weight, egg figure exponential,eggshell strength and the content of calcium,observing eggshell ultrastructure of out surface and transect through scan electron microscopy,the relationship between eggshell colors and egg quality as well as eggshell ultrastructure was studied. The results showed that with the eggshell color deepening,the eggshell weight,eggshell strength,eggshell thickness and egg figure exponential were bigger, and the content of calcium in eggshell,albumen and yolk increased. The number of air hole in shallow color eggshell was more than that of deep color eggshell.
