Impact of Egg Weight Selection on Body Weight of Japanese Quail

Abstract Text: The aims of study to determinate the direct selection response for egg weight and its correlated response on body weight at hatch and 6 weeks of age for Japanese quail during three generations. Results showed that, the cumulative response was 0.82 of base and two selected generations of selection for egg weight.  Moreover, overall mean of body weight at hatch for selected line (8.8g.) was higher than that for control line (8.4g.) by 3.92%, with significant differences between them as a correlated response of selection. Also, the corresponding values of body weight at 6 weeks were 179.9 g. vs with 169.6 g. increasing by 6.06% for selected lines with significant differences between them. In conclusion, increasing of body weight at hatch and 6 weeks of age as a correlated response can be obtained by direct selection for increase egg weight in Japanese quail.
