Effect of Probiotics and Prebiotics Supplemented Diets on Immune Resistance against Aeromonas hydrophila in Mrigal Carp - Abstract
The present study was made to test the effect of probiotics and prebiotics on disease resistance. Three treatments were designed including a control, probiotics (Enterococcus faecalis) and prebiotics (Rice bran) incorporated in the fish feed which was administrated for a period of 45 Days. Results showed that probiotics and prebiotics on oral administration resulted in improved Serum lysozyme count, Serum bactericidal activity, Serum protein level, Serum globulin level, Hematological parameters such as, Leukocyte count, Red blood cell count, and Packed cell volume. The mortality rate after challenge with Aeromonas hydrophila was significantly low in fish fed control-65%, probiotics-40%, prebiotics-30%. The present study suggests that probiotics and prebiotics supplemented diet enhances the disease resistance to Aeromonas hydrophila in Cirrhinus mrigala.
