Effect of Biogut on Growth Performance of Cyprinus carpio (Linn.) Fingerlings.

In this study we evaluated the effect of three levels of Biogut (a probiotic) on growth performance of common carp fingerlings. Biogut was incorporated into a formulated diet (protein level: 35%) at 0.5, 1.0 and 1.5% of the diet and designated as T1, T2 and T3 and T0, the fourth (control) diet, without biogut. The diets were fed to common carp fingerlings, stocked at 10/tank, with three replicates, for 60 days. Results indicated that the common carp fingerlings fed with the diets containing biogut exhibited increased growth compared to those fed the control diet. The survival rate was 100% in all the groups. The average weight and length of common carp was maximal in the 0.5% biogut treated group. Specific growth rate, protein efficiency ratio, RNA/DNA ratio and protease activity were also highest in the group fed on 0.5% biogut. The results demonstrate that 0.5% biogut supplementation in the diet of common carp fingerlings produces positive effects.
