This study evaluated the effect of canola meal and oil in quail diet on productive performance, egg quality and bone characteristics. Quails (n = 84) with 150-days-of-age and average weight of 234 [+ or -] 17 g were used in this experiment that lasted 84 days. The experiment consisted of a completely randomized design with 4 treatments, 7 replications with 3 birds each. Four diets were formulated: SM+SO--control diet with soybean meal and oil; MC+SO--25% replacement of soybean meal with canola meal; MC+CO--25% replacement of soybean meal with canola meal and complete replacement of canola oil with soybean oil; SM+OC--control diet with soybean meal and canola oil. Productive performance, internal and external egg quality and bone characteristics were evaluated. The diet with canola meal and oil (MC + CO) decreased (p <0.05) feed conversion. Albumen height was lower (p < 0.05) for treatments with canola meal and oil (MC + CO). Regardless of the oil used, the dietary canola meal (MC + SO and MC + CO) reduced the weight and length of tibia (p < 0.05), but increased its ash content (p < 0.05). The mixture of canola oil and meal decreases feed conversion, and negatively affects internal egg quality and bone characteristics of quails. Keywords: alternative ingredient, performance, nutrition. Este estudo avaliou o efeito do farelo e do oleo de canola na dieta de codornas sobre o desempenho produtivo, qualidade de ovos e caracteristicas osseas. Foram utilizadas 84 codornas com 150 dias de idade e peso medio de 234 [+ or -] 17 g por um periodo de 84 dias. Foi utilizado um delineamento experimental inteiramente ao acaso, com 4 tratamentos, 7 repeticoes com 3 aves cada. Foram formuladas quatro dietas: FS+OS--dieta controle com farelo e oleo de soja; FC+OS--25% de substituicao dofarelo de soja pelo de canola; FC+OC--25% de substituicao do farelo de soja pelo de canola e oleo de canola substituindo totalmente o oleo de soja; FS+OC--dieta controle com farelo de soja e oleo de canola. Foi avaliado o desempenho produtivo, a qualidade interna e externa dos ovos e as caracteristicas osseas. A dieta com farelo e o oleo de canola (FC+OC) piorou (p < 0,05) a conversao alimentar. A altura do albumen foi menor (p < 0,05) para os tratamentos com farelo e oleo de canola (FC+OC). Independentemente do oleo utilizado o farelo de canola (FC+OS e FC+OC) na dieta reduziu (p < 0,05) o peso e o comprimento das tibias, porem aumentou (p < 0,05) o teor de cinzas. A mistura de oleo e farelo de canola piora a conversao alimentar, afeta negativamente a qualidade interna dos ovos e as caracteristicas osseas das codornas.
