A total of two hundred, straight run day old chicks were utilized for studying the growth performance from day old to five weeks of age. After fifth week of age, female birds were maintained to study the age at sexual maturity and egg production parameters. Molecular genetic characterization was carried out by using randomly selected each 24 male and females. The mean body weight of “TANUVAS Namakkal gold Japanese quails” from 0 to 5 weeks were 8.96 g ± 0.02, 26.63 g ± 0.32, 63.15 g ± 0.39, 111.15 g ± 2.91, 171.09 g ± 1.15 and 212.10 g ± 1.37, respectively, whereas weekly feed consumption per bird from first to fifth week were 37.61 g ± 0.16, 99.33 g ± 0.29, 152.00 g ± 3.39, 187.00 g ± 3.39 and 208.87 g ±1.91, respectively and the feed conversion ratio from first to fifth week were 2.45 ± 0.06, 2.53 ± 0.02, 2.84 ± 0.06, 2.94 ± 0.03 and 3.37 ± 0.03, respectively. The mean age at sexual maturity, age at 50 and 90 per cent egg production was 42.20 days ± 0.80, 50.30 days ± 1.59 and 59.10 days ± 2.92, respectively.EnglishThesis
