Abstrakt: The objective of this study was to determine the chemical composition and energy value of passion fruit seed cake (PFSC) and to evaluate the inclusion of different levels of PFSC in the diets for quails on growth performance, carcass quality, litter quality, lipid stability of the meat, and economic viability. In the metabolism assay, 108 European quails of 21 days of age were used, being distributed in a completely randomized design with 3 treatments (one reference ration and two test rations with substitution of 20% and 40% of the reference ration by PFSC) and 6 replications of 6 birds each. It was observed that the apparent metabolizable energy corrected by the nitrogen balance (AMEn) determined in the ration with 20% PFSC (3876.17 kcal/kg DM) was higher than in the 40% (3469.00 kcal/kg DM). In the performance assay, 432 European quails from 7 to 42 days of age were used, being distributed in a completely randomized design with 6 treatments, consisting of a control diet and the others with increasing levels of inclusion of passion fruit seed (5, 10, 15, 20, and 25%), and 6 replications of 12 birds. It was observed that the inclusion of PFSC starting from 10% promoted increase FI and FC values, and increasing linear effect of these variables starting from 5% of inclusion. The PFSC did not affect the carcass characteristics and lipid oxidation of the meat. Regarding the litter quality, there was a linear increase in the pH values and worse economic indexes starting from the inclusion of 10% of PFSC. In conclusion, PFSC can be used up to the level of 5% in diets for meat quails from 7 to 42 days of age.
