Avaliação nutricional e utilização do resíduo da polpa do maracujá em rações para codornas de corte.

Abstract

Two trials were carried out to evaluate the nutritional and energy composition, metabolizable coefficients of the passion fruit pulp residue and its inclusion in feed of cut - off quail from one to 42 days of age. In the first experiment, 90 quail (Coturnix coturnix) were used for the metabolism assay, distributed in a completely randomized design with two treatments, five replicates and nine birds per experimental unit. The total excreta collection method was used to determine the energy value and composition of the passion fruit pulp residue. The treatments were constituted in reference ration and test ration with 12% inclusion of the pulp residue of the passion fruit. The passion fruit pulp residue presented 2,925.75 kcal of AME/kg, 2,922.09 kcal of AMEn/kg, 20.86% of ethereal extract and 10.72% of crude protein, showing a good potential of use for the diets of cut quails. In the second experiment 225 European quails were used, one day old and distributed in a completely randomized experimental design with five treatments (0%, 3%, 6%, 9% and 12% inclusion of the passion fruit pulp residue) five replicates and nine birds per plot. The inclusion of different levels of passion fruit pulp residue did not present a significant effect (p>0.05), for feed intake, weight gain and feed conversion, from one to 21, 22 to 42 and from one to 42 days of age. Likewise, no significant effect (p>0.05) was observed for carcass yield, noble cuts and edible visceras of quails at 42 days of age. For economic viability, the 12% inclusion level presented the best results. The passion fruit pulp residue can be included up to the 12% level, without affecting the productive performance and carcass characteristics, and its economical use in the formulation of diets for european quails destined to the production of meat in the period of one to 42 days of age.
