Eggshell surface properties. (A) comparison of the contact angle measurements on the surface of eggshells of eggs laid by hens from different ages or bleach-treated eggs (no cuticle) (n = 24, ANOVA, Tukey-multiple means comparison; p < 0.05) and (B) A comparison of the contact angle measurements on the eggshell surface between eggs that were graded/ungraded eggs compared to bleach-treated eggs. The contact angle of the surface of the bleach-treated eggs was lower than graded or ungraded eggs. The values with different superscript letters (Tukey multiple means comparison) are significantly different (ANOVA, Tukey multiple-means comparison; p < 0.05). The values represent the mean ± standard deviation (n = 72).
