Abstract

The correlations between selected egg, embryo development, and chick traits were analyzed in three lines of Japanese quail subjected to intrafamily selection for 28th day body weight (group S) and in three lines of random control birds (group K). The significant correlation coefficients between egg weight and most of the traits observed after the first two days of incubation as well as chick weight and shank length were estimated. Most of the correlations obtained were significant in both groups. No statistically significant differences between groups were confirmed, but there was a lines effect within the groups in most cases and a strong nest effect in every analyzed trait observed.
