Relationships among egg quality traits in Japanese quails over three generations of selection for egg production

Abstract

The study was carried out to evaluate the relationships among egg quality traits over three generations of
selection for egg production. Eggs were obtained at the 9th week from 300, 450 and 320 adult quails in
Generation zero (G0), one (G1) and two (G2), respectively. There were significant (p<0.05-0.01) positive
and negative correlations among egg quality traits as generation of selection increased. The high positive
relationships between egg weight and shell weight, shell thickness and albumen weight could be maximized
in designing a selection program for egg quality traits in quails.
