T1: (control) standard diet with 0% of Agaricus bisporus, T2: 3% of Agaricus bisporus without enzymes, T3: 3% of Agaricus bisporus with enzymes, T4: 9% of Agaricus bisporus without enzymes and T5: 3% of Agaricus bisporus with enzymes. Results a significant enhance (P<0.05) in antigens against Newcastle and Gumboro diseases, hemoglobin rate, PCV, red blood cells and white blood cells in the chicks that fed on diets contained 9% of Agaricus bisporus with enzymes.
