The objective of this work was to determine the effect of inclusion levels of dietary fiber in the Japanese quail diets. 480 Japanese quail were distributed in a completely randomized design, with 5 treatments and 12 replicates composed of 8 birds each. The treatments were constituted by five increasing levels of fiber in the diet: 2.78; 3.08; 3.38; 3.68; 3.98%. The parameters of productive performance, water consumption, egg quality, total lipids in the egg, excreta humidity, weight of digestive organs and intestinal morphology were evaluated. There was no significant effect of the use of different fiber levels on feed intake, egg production, viability, live weight, relative and absolute weight of gizzard, small intestine and cecum, and in excreta moisture of Japanese quais. Higher dietary fiber levels resulted in improvements in feed conversion per mass and per dozen eggs and higher water consumption. There was no significant difference for egg quality, except fot the color of the yolk where it was observed higher pigmentation of this structure with higher levels of fiber inclusion, and the lipid concentration in the buds was influenced in a quadratic manner. The inclusion of fiber promoted improvement in the villi of the duodenum and cecum.
