Influence of different levels of bio stimulant Bacillas coagulans with vitamin E in diets of common carp fingerlings on hematological and biochemical traits

Abstract

         Abstract A laboratory experiment was conducted for 60 days by adding three different levels of  Bacillas coagulans with a constant level of vitamin E to the diets of common carp fingerlings for a goal of study their effects on some blood and biochemical traits. Average weight of Fingerlings were  11.2±0.13 g، and treatments included : T1(Control treatment) without addition, T2 vit.E only vit.E (100mg/kg) ,T3 same ratio of vit.E with the bio stimulant B.coagulans (150mg/kg), while T4 vit.E with (200mg/kg) bio- stimulant , and (250mg/kg) vit.E in T5.

Experimental results indicated that: Significant differences (P≤0.01) in all blood indicators studied between different experimental treatments. Control treatment recorded a significant difference at red blood cells (RBC) amounting to 4.20± million / ml and hemoglobin (Hb) 6.30±0.05 g/deciliter, packed cell volume (PCV) 22.0±0.57% and white blood cells (WBC) recorded at 9.20×10⁹/liter, which are values representing the normal basal levels. In contrast, cellular immune indicators improved, represented by the percentages of (lymphocytes,  monocytes , eosinophils and neutrophils) in the supplemented treatments. Blood chemistry profile showed superiority by treatment T4 in protein percentage and recorded the lowest blood sugar level. Cholesterol also decreased in all supplemented treatments compared to the control, while T3 recorded highest level of triglycerides and lowest level for enzymes liver..
