Resumo: ABSTRACT This study evaluated the performance, egg quality, relative weight of the gastrointestinal organs, and the intestinal morphometry of laying quails fed diets containing levels of dried cassava residue (DCR). A total of 120 150-day-old Japanese quails were distributed in a completely randomized design with five treatments (0.0; 2.5; 5.0; 7.5; and 10.0% of DCR), four replicates, and six birds per experimental unit. The dietary inclusion of DCR did not affect (p>0.05) performance, internal egg quality, yolk color, and the values of villus height, crypt depth, and villus height/crypt depth ratio for the segments of the small intestine. However, a linear increase (p<0.05) was found for eggshell thickness, relative weight of the gizzard, and small intestine with increased dietary levels of the residue. For the relative weight of the pancreas, a quadratic effect (p<0.05) was observed, with the lower relative weight estimated at 4.04% DCR inclusion. Comparing to the control group (0% of DRC inclusion) the quails fed 5% of DRC showed a lower relative weight of the pancreas. The inclusion of up to 10% of dried cassava residue in laying quail’s diets does not interfere with the performance. Among the organs of gastrointestinal tract, the inclusion of dried cassava residue increased the relative weight of gizzard and small intestine. In addition, it improves eggshell quality by increasing eggshell thickness.
