Abstract

This study was carried out to evaluate the effect of using probiotic Pediococcus acidilactici and Natuzyme multi enzyme in diets on growth indices and hematologic parameters in Huso huso juveniles. This experiment was conducted as a completely randomized design in 5 treatments and 3 replications. Probiotics and multi enzyme in 6 levels include, 0.1% probiotic, 0.025% multi enzyme, 0.05 multi enzyme, compound of probiotic (0.1%) and multi enzyme (0.05), compound of probiotic (0.1%) and multi-enzyme (0.05%) and control group were added to the diet and fed to experimental diets for 8 weeks and growth factors include: weight gain, specific growth rate, feed conversion ratio and food efficiency ratio Was investigated. Blood factors such as hemoglobin, hematocrit, WBC, RBC, MCV, MCH, MCHC were measured and evaluated. On the probiotic level 1 and multi enzyme 3, as well as probiotic level 2 and multi-enzyme level 3, they had the most significant effect on final weight, weight gain, SGR and efficiency ratios was the most effective and have a significant effect on the control group (p< 0.05). The level of FCR in the level of probiotic 1 and multi enzyme 3 showed the lowest and had a significant effect on the control group (P <0.05). Different probiotic and enzymatic levels had no significant effect on blood factors (P >0.05). The results of this experiment showed that the use of multi-enzyme and probiotic can influence on fish growth factors and improve the growth and nutrition status of Beluga.
