| Popis: | This study aimed to evaluate the inclusion of parboiled rice bran (PRWB) in diets of Japanese quail in the growing and production. In the first experiment, we used 324 Japanese quails with seven days of age, distributed in a completely randomized design with six treatments and six replications of nine birds. Treatments consisted of six diets isonutritives, being a control diet without PRWB and the other containing 5, 10, 15, 20 and 25% of PRWB. The diets were offered ad libitum within 7 to 42 days and at the end of the growth phase the birds were transferred to the production hall being fed the same ration posture for 63 days. In the growth phase, the inclusion of PRWB above 5% linearly reduced digestibility of dry matter and gross energy of the feed, and from 14.27% in nitrogen digestibility, having, however, a linear increase in metabolizing energy. Feed intake, weight gain and final weight reduced without changing the feed conversion and body composition. During production, the addition of PRWB in the diet increased the growth of age at first egg production without influence (p |
