The experiment aimed to measure the correlated response of selection for high egg weight of the first 10 eggs laid at the beginning of egg production period (EW10) and its correlated responses with growth performance in Japanese quail through three generations of selection. The overall mean of EW10 for selected lines has higher value (11.63 g) than that for control lines (11.16 g) with a significant difference among generations and between lines. Body weight at hatch, 2, 4 and 6 weeks of age has highly significant differences among generations and between lines. However, the differences between sexes were significant for only BW6. The selection for EW10 has positive effect on BW0 of both sexes in Japanese quail. The selection for EW10 in Japanese quail has different magnitude on BW4, positive effect on male and negative effect on females.
