The effect of probiotic Pediococcus acidilactici on growth performance, blood and some serum parameters in Caspian salmon (Salmo trutta caspius)

The effect of probiotic Pediococcus acidilactici on growth performance, blood and some serum parameters on Caspian salmon (Salmo trutta caspius) was studied. An experiment was designed with five treatments each with three replicates. Two hundred and seventy Caspian salmons average (±SD) initial weight of 6.9 ± 0.1 g were assigned to fifteen experimental tanks. The experimental period was eight weeks. At the end of this period, the growth parameters were measured. In addition, after 8 weeks feeding on experimental diets, hematological parameters and metabolic products (cholesterol, glucose and total protein) were measured. Results showed that feed conversion in five treatments (0.4 g probiotic) significantly was lower than control group. Specific growth rate, final weight and weight gain in treatments (0.2 g) compared with the control group significantly increased. Use of probiotics in the diet, showed no significant differences in hemoglobin, hematocrit and mean cell hemoglobin concentration (MCHC). The mean cellular hemoglobin concentration (MCH) and mean corpuscular volume (MCV) were significantly increased in five treatments (0.4 g) compared with the control group, but significantly decreased red blood cell counts (RBC) in five treatments. White blood cells also increased the amount of probiotics 0.2 g. The results of this study indicated that 0.2 g/kg Pediococcus acidilactici probiotics in the diet could be a useful food supplement and should be used to improve the growth parameters in Caspian salmon.
