BACKGROUND: Germinated Barely and Earth Apple were used as a source of prebiotic to enhance fish health and welfare. OBJECTIVES: The effect of adding different levels of both germinated barley and earth apple powders in Cypri-nus carpio diets was evaluated. METHODS: First Diet (Control diet free of any additives), diets in treatments of 2, 3, 4, 5, 6 and 7 with 2.5, 5, and 7.5 gr/kg diet of each of barley and earth apple powders respectively on an equivalent basis of protein. RESULTS: T4 with 7.5 gr Earth apple was higher significantly (P≤0.05) in Gill index. T5 with 2.5 gr Barley was significantly higher (P≤0.05) in the Kidney index. Spleen somatic index was higher in all treatments except for T2 and T4. T2 and T5 were significantly higher in the Hepatosomatic index. Using germinated barely and earth apple powder in intestine indices either weight or length, the T7 with 7.5 gr Barley has more impact on the fish intestine. T3 with 5 gr Earth apple was higher significantly (P≤0.05) in each meat index in terms of Fish weight without viscera and Fish weight without viscera & head. CONCLUSIONS: Earth Apple powder as a source of prebiotic enhances the health parameters in biological pa-rameters (P≤0.05).
