Abstract: 

BACKGROUND: Study of heritability, genetic and phenotypic correlations of internal egg quality traits.
OBJECTIVES: The aim of this study was to evaluate of heritability, genetic and phenotypic correlations of internal egg quality traits in Azerbaijan native fowls.
METHODS: Statistical models for all traits were fitted using GLM procedure of SAS software. Fixed effects including generation and incubation time were significant (P < 0.01) for all traits except for yolk hright. In the first section, eight univariate animal models were compared for estimation of heritability and other genetic parameters and the most appropriate model for each trait was determined based on deviance information criterion (DIC). The genetic and phenotypic correlations between certain traits were also estimated through a multivariate animal model.
RESULTS: Results showed that direct heritability estimations for egg quality traits ranged from 0.12 for Haugh unit to 0.46 for yolk depth. There were high positive genetic and phenotypic correlations between albumen height and Haugh unit (0.96) as well as between egg weight and albumen weight (0.87).
CONCLUSIONS: Egg quality traits especially Haugh unit as a trait in the selection index, could be useful to improve internal egg quality in eggs of Azerbaijan native fowls.
