The main objective of the present work was to study the effect of feeding Japanese quails on diets containing some aquatic plants, (Azolla and Spirulina) on Japanese quail performance, carcass traits and some blood parameters. The experimental treatments were T₁ (control without additives), T₂ (4% Azolla), T₃ (8% Azolla), T₄ (12% Azolla), T₅ (16% Azolla), T₆ (T₁ + Spirulina 2.0 g/kg diet), T₇ (T₂ + Spirulina 2.0 g/kg diet), T₈ (T₃ + Spirulina 2.0 g/kg diet), T9 (T4 + Spirulina 2.0 g/kg diet) and T10 (T5 + Spirulina 2.0 g/kg diet). The obtained results showed that birds fed experimental diets in T5 and T10 achieved high significant values of final body weight, total weight gain and the best total feed conversion. Serum concentration of total protein, albumin, globulin. The experimental diets of T6 and T10 achieved the high significant values of carcass and total edible parts percentage. It is concluded that Japanese quails fed experimental diets containing Azolla and Spirulina improved bird's performance and carcass traits and did not negatively effect on blood serum characteristics.
