Description:
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.
