The experimental stock of 84 quails was divided into 3 groups 28 birds (20♀ and 8 ♂ each (each group was replicated). Group I was fed a standard diet with a 25% admixture of ground corn. Group II was offered a feed in wich ground com was partly (10%) substituted with covered oat. The feed fed to Group III contained a 20% admixture of naked oat. The Group III birds showed the highest daily feed intake (30.4 g per bird), the lowest feed conversion ratio (35.6g per egg), and the highest egg yield (132 eggs/female). The mortality in Group III was the same as that in the control (7.1%). During the first two hatchings the best hatch rates were recorded in Gr. III (84.4 and 80.5% for hatching 1 and 2, respectively). During the final hatching, the hatches rates in Group III detoriated markedly (66.6%), a clear improvement (82.5%) beeing seen in Group II.
