The aim of this study was to evaluate the productive performance of growing quail (Coturnix coturnix japonica) fed with a commercial balanced feed and supplemented with mulberry meal (Morus alba). The experiment was carried out in Trujillo, Venezuela, for six weeks. A completely randomized design was applied with three treatments (diets) and five repetitions per treatment (4 birds per repetition). The diets were: T0: 100% commercially balanced feed (AB); T1: 90% AB + 10% of mulberry meal (HM); T2: 80% AB + 20% HM. The final body weight (FW), daily weight gain (DWG), feed consumption (DI), specific growth rate (SGR), feed conversion (FC), carcass yield (CY), mortality and cost-benefit ratio were determined (CB). The data were processed by analysis of variance using the GLM procedure of the SAS program. The FW and the DWG were higher in T1 and T2 (PF: T0: 139.1 ± 1.9, T1: 147.2 ± 2.0, T2: 147.1 ± 1.9, (p<0.03) (DWG: T0: 3.1 ± 0.05, T1: 3.3 ± 0.05; T2: 3.3 ± 0.05 (p<0.03). The birds of T1 and T2 consumed more feed than those of T0 (p<0.01). The SGR was lower (p<0.05) in T0 (7.01%) than in T1 (7.13%) and T2 (7.14%). FC and CY did not vary between treatments. The CB ratio favored the birds of T1 and T2. It is concluded that the addition of HM in the ration improved FW, DWG and CB, constituting an alternative to reduce the feeding costs of the commercial farms without diminishing the productive indices of the birds.
