The main purpose of this experimental study was to determine the appropriate amount of Moringa oleifera leaves meal (MOLM) fermented with activated effective microorganisms (EM-A) to be incorporated into the diet of fry Oreochromis niloticus to obtain best growth performance.
Fish were fed
experimental diets containing 5 differentiates of MOLM + EM-A incorporated: RI
= 0% (Moringa + EM-A); R2 2.5% (Moringa + EM-A); R3 = 5% (Moringa + EMA)
R4 = 7.5% (Moringa + EM-A); R5 = 10% (Moringa + EM-A). The results
showed that the mean weight gain (MWG), specific growth rate (SGR) and food
conversion rate (FCR) were higher in fry fed the diet containing 2.5% MOLM+
EM-A followed by the fry fed 7.5% MOLM + EM-A. The daily mean weight gain
(DMWG) was in favor of fry fed the diet containing 2.5% and 7.5% MOLM + EMA.
The fry fed diets with 0, 5 and 10% MOLM + EM-A presented comparable
DMWG. The protein and lipids of the muscle were higher in fry fed diets
containing 0 and 2.5% MOLM+ EM-A followed by other diets (5, 7.5 and 10%
MOLM + EM-A). Survival rate is relatively high and ranged from 85 to 100 %.
From these results, the present conclude that the diet containing 2.5% MOLM +
EM meets the best growth performance of fry Oreochromis niloticus. Future
studies may be conducted to focus on the effects of these different diets on
biochemical digestion in Oreochromis niloticus.
