title: Growth performance and feed utilization of keureling fishTor tambra(Cyprinidae) fed formulated diet supplemented with enhanced probiotic.
abstract: BackgroundThe objective of the present study was to determine the optimum dosage of probiotic in the diet of keureling fish (Tor tambra) fry.MethodsLactobacillus caseifrom Yakult® was used as a starter, and enhanced withCurcuma xanthorrhiza,Kaempferia galangaand molasses. The mixture was fermented for 7 days prior to use as probiotic in a formulated diet containing 30% crude protein. Four levels of probiotic dosage; 0 ml kg-1(control), 5 ml kg-1, 10 ml kg-1and 15 ml kg-1were tested in this study. The fish was fed twice a day at 08.00 AM and 06.00 PM at the ration of 5% body weight for 80 days.ResultsThe results showed that growth performance and feed efficiency increased with increasing probiotic dosage in the diet from control (no probiotic) to 10 ml kg-1of probiotic dosage and then decreased when the dosage was increased up to 15 ml kg-1.ConclusionsThe best values for all measured parameters were recorded at the dosage of 10 ml kg-1. Therefore, it was concluded that the optimum dosage of enhanced probiotic forT. tambrafry was 10 ml kg-1of feed.
