Genetic parameters for body weight and egg production

1Poultry Production Dept., Faculty of Agriculture, Fayoum Reliable estimates of heritability and correlations are necessary to predict the direct and indirect selection responses. Therefore, the present study was conducted to estimate the heritability, genetic and phenotypic correlation coefficients of body weights (BW), shank length (SL) recorded at different ages, growth rates (GR)

AFE and EW had a negative correlation with EN 40 and EN 50 at genetic and phenotypic levels. EN 40 and EN 50 had positive high association both at genetic and phenotypic lev els. In general, standard errors of genetic correla tion were higher than the estimates indicating the poor precision of genetic correlation. KEYWORDS: Correlation, Heritability & Poultry
