effect of dietary spirulina platensis and natuzyme multi-enzyme on growth performance, survival and hematological parameters in common carp (cyprinus carpio)

the aim of this study was to investigate the effect of using spirulina algae and natuzyme multi-enzyme in the diet of common carp on growth performance, survival and hematological parameter for 60 days. for this, 540 pieces of common carp fry with an average weight of 102±0.2 g were prepared and under 8 treatments including: 1% spirulina algae powder, 2% spirulina algae powder, 0.05% natuzyme multi-enzyme, 0.1% natuzyme multi-enzyme, combination of spirulina powder 1 and 2% and natuzyme multi-enzyme 0.05% , combination of spirulina powder 1 and 2% and natuzyme multi-enzyme 0.1% and control group each with 3 replicates were fed daily 3% of body weight. at the end of the experiment, bioassays were performed on all fish to examine growth indices. in order to perform hematological examinations, blood sampling of all treatments were completely randomly performed. the results of this study showed that the treatments fed a diet containing a combination of 2% algae powder and 0.1% natuzyme multi-enzyme had a higher rate of weight gain, specific growth rate and feed conversion ratio compared to other experimental treatments p<0.05 . however, the survival percentage was not significantly different between the treatments and the control group p <0.05 . also, the results showed that there was no significant difference in hematological parameters between treatments fed wih spirulina powder and natuzyme multi-enzyme single and in combination from the control group p <0.05 . in addition, the number of white blood cells, red blood cells, hemoglobin and hematocrit in all treatments were not statistically different from each other p <0.05 . in general, due to the positive effects of combining spirulina algae powder at 2% of the diet and natuzyme multi-enzyme at 0.1% of the diet, adding them is recommended to the diet of common carp.
