Uso de subprodutos do arroz na alimentação de codornas do tipo corte

Abstract

In order to evaluate the effects of replacing corn for broken rice (QA) and the inclusion of parboiled rice bran (FIAP) in rations for meat quails, two experiments were conducted in the period 7 to 49 days age. In each trial, 288 quails with seven days of age were distributed in a completely randomized design with six treatments and six replications of eight birds for experimental unit. In the first experiment, was tested the levels of 0, 20, 40, 60, 80 and 100% of replacement corn by broken rice and it was observed that the replacement of corn for broken rice did not significantly influence the performance and carcass characteristics of quails at different stages of creation, neither economic viability. In the second experiment, the treatments were a control diet without the inclusion of FIAP, and the other containing 5, 10, 15, 20 and 25% of FIAP. There was a linear decrease in the apparent digestibility of dry matter (CDMS) and crude energy (CDEB) and a linear increase of apparent metabolizable energy (EMA) and apparent metabolizable energy corrected for nitrogen (EMAn) with the inclusion of FIAP in rations, above 5%. Therefore, there was a linear decrease in feed intake and weight gain, without influence in feed conversion, carcass characteristics and parameters of bone quality. Although there was some reduction parameters when FIAP increased above 5%, the performance of birds fed with different levels of FIAP was similar in relation to the control group. Furthermore, the use until 25% of FIAP provided better economic viability. It can be argued that the broken rice can replace corn in the feeding of meat quails at levels up to 100%, while the FIAP can be included in rations in proportions of up to 25% without affecting carcass characteristics.
