This current work was conducted to determine the effect of dried carrot (Daucus carota) leaf powder at different amounts on some external and internal egg characteristics of Hy-line white laying hens as a commercial type through two-way ANOVA, to estimate the Pearson correlation between pairs of egg external and internal characteristics and to predict each of egg internal characteristics from egg external characteristics, treatment and week through CHAID analysis. A total number of eighty, 56 weeks old Hy-Line White laying hens (commercial type) of nearly similar initial body weight (1360.6±14.25 g) were assigned into 5 experimental groups (control group and 4 treatment groups) each including 16 and maintained individually in cages of 35 x 40 x 45 cm. The strongest correlations were found for egg weight-egg width (r=0.910, P<0.01), haugh unit-albumen index (r=0.876, P<0.01), egg weight-egg height (r=0.799, P<0.01), and egg shape index-egg height (r=0.693, P<0.01). ANOVA results revealed that treatment factor influenced only egg height among all the egg characteristics (P<0.05). The effect of treatment by week interaction on all the characteristics was non-significant. The significant differences in other egg characteristics between weeks were recorded except for egg shape index and egg height (P<0.05). Very strongly Pearson coefficient of 0.876 was estimated in egg shape index between predicted and actual values (P<0.01) in the CHAID analysis in comparison with other egg internal characteristics. The Nodes numbered 3, 4, 5, 8, 9 and 12 with the egg shape index of 72-76 in the CHAID analysis illustrated suitable eggs for egg cartons and shipment in poultry industry. As a result, it was determined in the study that CHAID analysis may be used to better prove relationship mechanism between egg quality characteristics which are of great importance for higher price and more income of fertile and table eggs.
