Effect of aqueous moringa (Moringa oleifera) leaf extract as a prebiotic on growth of the whiteleg shrimp, Penaeus vannamei Boone, 1931 (Decapoda, Penaeidae)

Abstract This study evaluated the potential of aqueous moringa ( Moringa oleifera ) leaf extract (ME) as a prebiotic and its effect on growth performance whiteleg shrimp, Penaeus vannamei Boone, 1931. The trial probiotics in broth containing ME showed that Lactobacillus acidophilus rate was significantly higher than plantarum reuteri . Furthermore, L. exhibited also better Vibrio alginolyticus , parahaemolyticus harveyi ME. minimum inhibitory concentration (MIC) bactericidal (MBC) were same against V. at concentrations 10, 7.5, 7.5 mg/ml, respectively. By contrast, ME’s MIC MBC 50 >100 scores MIC, MBC, indicated enhanced more bacteria. Six diets formulated for feeding trial; 3 contained 0 (ME0), 2.5 (ME2.5) 5.0 g/kg (ME5.0), respectively, prepared with (ME0 + P, ME2.5 ME5.0 respectively). After trial, number lactic acid bacteria gut P group control groups, but no differences found vibrio-like bacterial count among treatments. had final weight, weight gain, specific did or alone groups. Therefore, exhibits function exerts symbiotic thus increasing P.
