In both experiments, the birds were distributed in five treatments according to their body weights, which were obtained at 42 and 35 days of age for the first and second experiments respectively, and the following categories were considered for said experiments: very light, light, average, heavy and very heavy. For both experiments, the treatments were distributed in a randomized block design, at eight repetitions per treatment for the first one and six for the second one, both at 18 birds per repetition. During the first experiment, sexual maturity, laying percentage, marketable egg percentage, average egg weight and egg mass, in second experiment, feed consumption, final body weight, eggs per bird present, laying percentage, average egg weight, egg mass and alimentary conversion were evaluated. The results obtained show that Japanese quails whose body weight is lower than 140 grams at 42 days of age, or lower than 120 grams at 35 days of age show significantly worse productive results during the laying phase. 2016 artículo científico 1806-2636 https://www.redalyc.org/articulo.oa?id=303159348014 https://www.redalyc.org/journal/3031/303159348014/ https://www.redalyc.org/journal/3031/303159348014/html/ https://www.redalyc.org/journal/3031/303159348014/303159348014.epub https://www.redalyc.org/journal/3031/303159348014/movil 10.4025/actascianimsci.v38i2.29858 en http://www.redalyc.org/revista.oa?id=3031 Acta Scientiarum.
