The body weights of female Japanese quail were regulated for 2 weeks from 7 days of age so that there became less weight 0, 10, 20 and 30% than a normal female quail, and thereafter quail were fed a diet with free access until sexual maturity. At sexual maturity, body growth, ovary growth and body composition were investigated. Age at sexual maturity was later for 20% and 30% groups than for 0% and 10% groups, but ovary weight and the size of ovarian follicle were not changed due to depressed body weight in early growing period. There was no difference in body fat deposition between groups, but body weight and body protein deposition were less for 20% and 30% groups than for 0% and 10% groups.
