Abstract

The aim of this study was to evaluate the effect of Lactobacillus acidophilus and Pediococcus pentosaceus  on hematological, immunological and growth parameters of common carp (Cyprinus carpio). 180 carp weighted 14±1.44 g were distributed in three treatments. Treatment 1: commercial diets with Lactobacilus acidophilus 1.5g/10Kg (1010CFUg-1),treatment 2: Pediococcus pentosaceus 1.5g/10Kg (1010CFUg-1) and treatment 3: commercial diets without probiotic diet were fed for 60 days. At the end of the experiment, 15 fish from each treatment were collected, hematological, immunological and growth parameters were measured. Based on the results, weight gain, neutrophil and monocyte percentages, lysozyme activity and C3 content in  treatments 2 and 3 were significantly higher than control. Hematocrit, RBC, hemoglobin, MCV, MCH in treatment 2 were significantly higher than other treatments. MCHC and lymphocyte percentage showed the highest values in treatment 3. There was no significant difference between IgM and C4 levels between treatments. The results of this study showed that the use of L. acidophilus and P. pentosaceus probiotics have positive effects on the growth parameters, hematological and immunological parameters of  juvenile common carp.
