| Abstract | ||
| This study was conducted on 220 chickens data progeny of 24 sire and 144 dam of white Leghorn was used. The aim of this study was to search for many egg, serum biochemicals and production characteristics ( yolk & serum cholesterol, first egg weight, egg production, egg weight and egg mass), in addition to study an age effects (24 & 28 wks) on egg cholesterol, then genetic parameters were compute. Results obtained showed that the yolk cholesterol mean was 16.56 ± 0.13 (mg./ gm. Yolk), result showed no significant effect of age on yolk cholesterol, in addition results showed low to intermediate heritability values, but genetics and phenotypic trend to be high significant values in the majority | ||
