Özet
This research was carried out to determine the relationships among egg quality characteristics in post molt eggs of Brown layer (H and N Brown Nick) and White layer (Hy-Line W-36) with used non feed-withdrawal programs (BB: Barley Based, WB: Wheat Bran Based and OB: Oat Based) and Feed Withdrawal method (FW). Eggs for analyses were sampled from 76-93 weeks in second production. About 160 eggs were sampled for each week and it lasted 16 weeks. In total, 2,560 eggs were examined. There were significant (p<0.01) positive correlation between egg weight and albumen height and shell thickness and shape index. No significant correlation between specific gravity and albumen height and shape index were determined. There were significant (p<0.01) correlation between egg weight and specific gravity and albumen height for both genotypes (-0.384 and 0.110 in white layers, -0.329 and 0.169 in brown layers, respectively. There were no significant correlation between specific gravity and albumen height for both genotypes. There were significant (p<0.01) positive correlation between specific gravity and albumen height for BB and OB programs but no significant correlation between specific gravity and albumen height for FW and WB programs were found.
