Abstract
The present study was carried out to evaluate the immunostimulant potential of
Nelumbo nucifera (Lotus). Formulated diets with different concentrations of ethanolic extract of
N.nucifera (D1=0%, D2=1% and D3=2%) were fed to Cirrhinus mrigala for 40 days, the
Specific Growth Rate (SGR) and Feed Conversion Ratio (FCR) were calculated significant
increase was observed in SGR &FCR. Then the experimental fishes were infected with
Pseudomonas aeruginosa and after 5 days the haematological parameters like Total Erythrocyte
count (TEC), Haemoglobin (Hb), Total leucocyte count (TLC), Differential leucocyte count
(DLC), serum total protein, serum albumin and globulin levels were analyzed. The TEC, Hb,
TLC, Lymphocytes and monocyte counts increased significantly in D3 diet fed fishes. Highly
significant increase was observed in serum total protein and albumin levels only. Globulin levels
remain unchanged. Basophil and Eosinophil counts decreased significantly. Thus N.nucifera in
fish feed preparations may be included as growth promoter and immunostimulator.
