Materials and Methods: First, two control diets were made of yellow corn (YC) and white corn (WC). Additionally, 10 diets were made by enriching the white corn-based diet with B.o grains and C.l rhizomes powders, at different incorporation rates. Second, three hundred sixty Coturnix coturnix japonica laying hens, 51 weeks old weighing 227.68±16.68 g, were randomly allotted to the 12 diets, with 10 birds in each, with 3 replications. Following, on the last day of week 8 (59 weeks old), the eggs were weighed. Then, three eggs of similar weights per diet were collected for analysis. To end, the eggs and their constituents were weighed and the yolks’ colours were assessed through L*, a* and b* measurements. Results: First, the best egg weights were obtained with WC+1% B.o, WC+0.15% B.o+0.45% C.l and WC+0.6% B.o diets for 11.31±0.21, 11.10±0.12 and 11.06±0.12 g, respectively.
