The inclusion of moringa leaf extract fermentation in commercial feed to enhance feed conversion ratio and specific growth rate of tambaqui fish, Colossoma macropomum.

Abstract

Abstract Probiotics could be used as an alternative substitute for Antibiotic Growth Promoter (AGP). One of the bacteria that have the potential as a probiotic was Lactobacillus acidophilus which was able to secrete digestive enzymes that could help digestion and absorption of feed nutrients. The activity of probiotic bacteria could be stimulated by giving Moringa leaf extract through the process of breaking down oligosaccharides into lactic acid. The purpose of this study was to determine the effect of giving Moringa leaf extract, L. acidophilus probiotic, and the interaction between Moringa leaf extract and L. acidophilus probiotic in commercial feed on the specific growth rate and feed conversion ratio of Tambaqui fish. The results showed that administration of Moringa leaf extract and administration of L. acidophilus probiotics to commercial feed with different doses did not have a significant effect (p> 0.05), but the interaction of the combination of Moringa leaf extract and L. acidophilus probiotics gave a significant effect ( p <0.05) on the specific growth rate and feed conversion ratio of Tambaqui fish, namely the A1B2 treatment (4.03% per day) for the specific growth rate and A2B1 treatment (0.92) for the feed conversion ratio.
