We assessed the effects of cereal type (corn-based, CB or rice-based, RB) and housing system (floor, F, or cage, C) on the performance of two Japanese quail genotypes (non-selected, JAP, and a Jumbo variety, JUM) in two, 2 × 2 factorially designed, experiments. In Exp. 1, during the 15-d experimental period, there were 4 experimental groups: JAP quail fed the CB diet, JAP-CB; JAP quail fed the RB diet, JAP-RB; JUM quail fed the CB diet, JUM-CB; JUM quail fed the RB diet, JUM-RB. Quail in each of the 4 groups (42 quail/group) were housed in 7 pens, each with 6 birds. In Exp. 2, there were also 4 experimental groups (42 quail/group, 7 pens, each with 6 birds) examined during a 19-d experimental period under two different rearing systems: JAP-F, JUM-F, JAP-CF and JUM-C. Genotype did not affect dry matter feed intake (DMI) in Exp. 1, but both JAP and JUM quail consumed more (PJAP-CB = JAP-RB = JUM-RB. Final BW was similarly higher (PJAP-CB. In Exp. 2, DMI was similarly higher (P
