Differences in the eggshell ultrastructure of hens laying eggs with different eggshell breaking strength. A Images of eggshell vertical profiles in high (HBS) and low (LBS) eggshell breaking strength groups under a scanning electron microscope. B Results of the eggshell ultrastructural characteristics. TT, total thickness; ET, effective layer thickness; MT, mammillary layer thickness. Data represent means with standard deviation based on 12 replicates with 5 eggshells each. An asterisk (*) indicates a significant difference (P < 0.05) between groups
