In this experiment the effect of dietary administration of probiotic Pediococcus acidilactici and multi-enzyme apsozyme on growth indices, some blood biochemical parameters in common carp (Cyprinus carpio). For this purpose 216 fish with average weight of 27.52±0.21 gr, were fed diets supplemented for 8 weeks. Trail was done using 8 experimental diet including probiotic (0.1%), multi-enzyme apsozyme (0.25% and 0.5%), combination of probiotic and multi-enzyme apsozyme and a control diet. At the end of feeding trial, growth indices, some blood biochemical parameters total pr, Alb, Glocuse were assessed using spectrophotometer. Results showed significant differences (P≤0.05) in weight gain, % weight gain, SGR among treatments. There was no significant difference in mentioned parameters in probiotic fed with control treatment, but significantly increased in Multi-enzyme fed with increasing levels (P <0.05). Also, in multi-enzyme and probiotic combination treatments, these indices showed significant increase compared to separate probiotic and multi-enzyme (P <0.05). Food conversion factor significantly decreased with increasing multi-enzyme level and in multi-enzyme and probiotic compound compare to probiotic and control diet (P <0.05). Survival percentage showed no significant difference between treatments (P≥0.05). Blood biochemical indices did not show significant difference between the amount of glucose and total protein in the control and other treatments (P≥0.05) but albumin increased in probiotic, multi enzyme and combination of multi-enzyme and probiotic compare to control (P <0.05). The results of this experiment showed that the using multi-enzyme and probiotic can affect the growth and blood biochemical factor and improve the growth and nutrition status in Common carp.
