Abstract
The experiment was conducted to demonstrate the effect of addition Lactobacillus reuteri with different levels of both inulin, and Jerusalem artichoke (Helianthus tuberosus) powder in common carp (Cyprinus carpio L.) fingerling diet, on growth performance and feed utilization: Weight gain (W.G), Daily weight gain (D.W.G), Relative growth rate (R.G.R), Specific growth rate (S.G.R), Feed conversion rate (F.C.R), Feed efficiency rate (F.E.R), and Protein efficiency rate (P.E.R). 60 fish were elected randomly distributed to five treatments, with three replications and 4 fish in each aquarium, per treatment, at a period of 07 days. Fish were fed at 3% of the weight of the biomass, feed prepared by protein ratio 28.95%, the control treatment without additives, 108 cfu/ml (colony formation unit )\ml were added to the meal provided for the first treatment, adding 2% inulin from the provided meal with 108 cfu/ml bacteria for the second treatment, for the third treatment, the meal containing Jerusalem artichoke powder was provided at 1% from the provided meal with 108 bacteria and the fourth treatment is by 2% Jerusalem artichoke powder from the provided meal, with 108 cfu/ml bacteria. These additions were provided with the nutrition program for research on Mondays and Thursdays of each week, with meals continuing to be given without additions for the rest of the days. The fourth treatment significantly (P≤0.05) exceeded for all growth parameters criteria, It did not differ significantly (P≤0.05) from the third treatment for weight gain criteria over all treatments, the feed utilization criteria, fourth treatment showed significantly (P≤0.05) exceeded over all treatments for all characteristics, it did not differ significantly (P≤0.05) from the third treatment for feed conversion rate and feed efficiency rate criteria.
