ABSTRACT
Digestibility of carbohydrates in fish is relatively low because of the availability andactivity of the amylase enzyme in the digestive tract of fish is quite small. This study aimed at evaluating the role of probiotics in the addition of a high carbohydrate-based feed to improve growthperformance of tilapia(Oreochromisniloticus).This study consisted of 4 treatmentswith 3 replicates,namely controls, 0.5% ; 1% and 1.5%probiotics. The results showed that the greatest specific growth rate was found in the probiotic treatment of 1%, followed by that of 1.5%, 0.5% and the control, respectively. Similar results were also found in the feed efficiency, feed consumption, the population of bacteriain the digestive tract and the retention of feed, where the largest value contained in the probiotic treatment 1%,then followed by the probiotic treatment of 1.5%, 0.5% andcontrol treatment. Therefore, the addition of 1% probiotic in the highly carbohydrate-based feed can improve the growth performance of tilapia.
