Colonization of Lactobacillus rhamnosus GG in Cirrhinus molitorella (Mud Carp) Fingerling: Evidence for Improving Disease Resistance and Growth Performance

The use of probiotic bacteria can not only enhance the nutritional utilization fish feeds to produce more biomass but also provide a practically “safer” alternative farming industry reduce abuse antibiotics and drugs. This study investigated possibility colonizing Lactobacillus rhamnosus strain GG (LGG) intestine Cirrhinus molitorella (mud carp) fingerling. Colonization LGG was observed in gut tissue after 14 days administration with diet supplemented 1 × 108 CFU/mL LGG. Moreover, growth performance parameters LGG-supplemented group, including relative weight gain, feed conversion ratio efficiency, were found about two-fold higher than control group 60 days. In addition, fed an for showed substantial resistance against infection pathogenic bacterial Aeromonas hydrophila, survival rate up 57% compared group. summary, results indicated that as dietary supplement mud carp fingerling nutrition better protect hydrophila. insight industry, encouraging reduction drugs production market at manageable cost.
