The production performance and egg quality of laying hens receiving increasing levels of pearl millet grain in rations were studied. Two hundred 30-week-old LSL Lohmann white hens, allotted in a completely randomized design with five treatments, five replicates with 10 hens, were fed with 0, 25, 50, 75 and 100% of pearl millet grain in rations as corn substitute. The performance was evaluated by egg production, feed intake, feed conversion in terms of dozen eggs and egg mass, and egg quality measured as egg weight, shell, albumen and yolk porcentages. No differences among treatments were observed for all characteristics, but the yolk color index measured by the Roche fan indicated decreasing in yolk colour as the level of pearl millet increased. Pearl millet did not affect the production performance, and a synthetic or natural pigment should be included in rations.
