It was held three experiments to evaluate behavior in two periods, phenotypic correlation and equations validation of prediction to the egg quality traits on laying hens (Hy-Line Bronw) in the last phase of production. It was used 870 eggs coming from laying hens of two productive periods: Period I (75-77 weeks old) and Period II (85-87 weeks old), it was evaluated weekly all external and internal egg quality traits. In the second study, it was used 288 eggs from laying hens of Period II, in they were determined phenotypic correlation of the external and internal egg quality traits. Finally, in the third study were used 781 egg from laying hens (both periods) to validate 148 equations of predictions, proposals to estimate the egg quality traits. Diets based on corn and soybean meal wereused in both periods. Results of first study indicate that old age laying hens affect significatively (P<0.01) the majority of the measures directly and calculated traits of external and albumen quality, but yolk quality wasn't affected. Second study shows that phenotypic correlations of the egg quality traits in the last productive phase have similar responses at previous phases, and there aren't enough correlation between external and internal traits. In the third study was validated 10 equation of prediction, of which 4 were of external quality and 6 were of internal quality, all validated equations had as predictor variable a easy measuring trait.
