Comparison of Effects of Different Enzymic Levels Immnowall and Premalac Indices of Growth, Survival Rate and Body Composition in Cyprinus carpio

This study was undertaken to evaluate the effects of Immnowal and Premalac on feed intake, weight gain, food conversation ratio, specific growth rate, total length and survival of juvenile Common carp For this purpose, 300 fish were stocked in three replications at the VENIRO tanks and fed twice daily by 0, 0.5, 1 and 1.5 g/Kg of Immnowall and 0.5, 1 and 1.5 g/Kg of premalac for 8 weeks. Results show that Growth factors including Weight gain, specific growth rate, growth rate, feed conversion ratio and body weight index for fish administrated by 0.15 percent Immnowall showed a statistical significant differences (Pless than0.05) by control. Protein rate increase in probiotic treatment ( 4, 5 and 6 with 0.05, 0.1 and 0.15 percent premalak in diet) of carcass analysis and showed a statistical significant differences (Pless than0.05) by control. Moreover, fish fed by 0.1 percent Immnowall, 0.05 percent Premalac and 0.15 percent Premalac multienzyme showed a significant difference (Pless than0.05) in higher survival rate than control.
