A 12-week feeding trial was conducted to assess the impact of fishmeal replacement with blood meal or dried porcine solubles on the growth performance, body composition and intestinal morphology of common carp (Cyprinus carpio). Fishmeal was 50% substituted with either blood meal or dried porcine solubles, or two-third substituted with both alternative products, at a 1:1 ratio. There was no significant difference in survival, final weight, weight gain ratio, feed conversion ratio or condition factor between the control and experimental groups (p > .05), although the visceral somatic index of the blood meal group was higher than that of the control group (p < .05). Crude lipid content was significantly higher in the dried porcine soluble group than that in the control group (p < .05), while other nutrient levels were not significantly different (p > .05). The amino acid composition of each experimental group was not significantly different from that of the control (p > .05). The intestinal villus height and fold depth of each experimental group were significantly lower than those of the control group (p < .05). The results of this study show that two-third fishmeal substituted with both blood meal and dried porcine solubles, at a 1:1 ratio, is the optimal fishmeal replacement for common carp growth.
