title: Evaluation ofMoringa oleiferaas a dietary supplement on growth and reproductive performance in zebrafish.
abstract: The leaves of theMoringa oleifera(Moringa) tree contain a significant source of protein, vitamins and minerals, and are considered as an important dietary supplement in countries where chronic malnourishment is linked to poor fetal development. We evaluated the effectiveness of theMoringaleaf as a supplemental replacement for vitamins, minerals, and protein in a formulated zebrafish diet and the impact that it may have on growth and reproductive outcome. Diets included a formulated control (FC) containing an array of vitamins and mineral supplements (pre-mixes), dried groundMoringaonly (M), formulated control minus vitamin and mineral pre-mixes (Fvm), and formulated control minus vitamin and mineral pre-mixes and supplemented withMoringa(FM). Juvenile zebrafish were fed experimental dietsad libitum. After a 12 week feeding period, each treatment group was evaluated based on growth and reproductive performance. The M treatment showed the least growth performance (length and weight gain) and no reproductive success (no egg production). Although small, M fish appeared otherwise healthy, with survivorship at ca. 70%, suggesting,Moringacan serve as a single ingredient source for a short period of time. FC showed the highest growth performance, and had the highest reproductive success. Growth performance and reproduction in the Fvm diet was greatly reduced. However, inclusion ofMoringa(FM) promoted significant, but not total, recovery of growth and reproductive metrics. These data suggest thatMoringaleaves can serve as an acceptable supplement for macro and micronutrients in the diet and could, in part, reduce problems associated with nutrient deficiencies.
