- Abstract
An experiment was conducted to determine the effect of the age at sexual maturity of Japanese quail dams in the egg production and egg quality traits of their progeny. The experimental birds consist of 100 females at 16 weeks of age, which individually recorded for the age at sexual maturity. The dams divided according to their age at sexual maturity to five groups as following, G1: 35-38 days, G2: 39-40 days, G3: 41-42 days, G4: 43-44 days and G5: 45-58 days. Males used randomly to produce the progeny of groups. The results showed significant differences among groups in the weekly number of eggs per female, egg mass and hen day egg production (%). No significant differences among groups in the number of cumulative eggs per female, cumulative egg mass and cumulative hen day egg production (H.D%). There were no significant differences among the groups in the egg shape index, shell thickness albumin height. There were significant differences among groups in yolk diameter, yolk color, yolk weight.
