Study of the hematological and some biochemical characteristics in common carp (Cyprinus carpio L.) fish feeding on fermented rations with varying concentrations growth stimulator (Bio boost aqua)

The current study was conducted to find out the influence of yeast on fermented rations. Saccharomyces cerevisiae, and to which the growth enhancer Bio Boost Aqua was added in different proportions to take into account some hematological and biochemical characteristics for common carp fish. The hematological results of the studied fish before and at the end of the experiment showed a significant (p≤۰.۰۵) superiority in T۲ over the other treatments in RBC and PVC%, respectively (۲۹.۵۱±۰.۷۰; ۲.۸۵±۰.۰۷), while T۱ and T۲ recorded a significant decrease in leukocyte count at a rate of (۲۵.۷۰±۰.۱۴; ۲۴.۵۰±۰.۱۴) compared to the other experimental treatments before and at the end of the experiment. The results did not show any significant differences (p>۰.۰۵) in the hemoglobin HB levels of the test fish before and at the end of the experiment. The results of the analysis of white blood cells at the end of the experiment (neutrophils, eosinophils and monocytes) showed that there were no significant differences (p>۰.۰۵) in the experiments studied. While the white blood cells (the lymphocytes) in the control treatment showed higher rates with a rate of ۳۶.۰۱±۱.۴۵% compared to the other treatments which recorded lower values. The biochemical results in experimental fish before and at the end of the experiment showed an increasing value of total protein in blood serum in T۲ and T۳, which showed significant differences (p≤۰.۰۵) at rates of (۲.۱۵, ۱.۹۵)%. Glucose levels showed a significant increase in T۴ levels (p≤۰.۰۵), reaching ۷۶.۵ mg/dL compared to the other experimental treatments where a decrease in levels was recorded before and at the end of the experiment. While the total cholesterol results for experimental fish before and at the end of the experiment showed that there were significant differences, T۳ and T۴ recorded higher values, reaching ۷۶.۴۹; ۷۱.۹۴ (mg/dl) compared to the other experimental treatments, which recorded a significant decrease in blood serum cholesterol analysis results p≤۰.۰۵.
