The effects of moringa leaf meal inclusion were investigated on growth performance, feed utilization and body composition of juvenile red hybrid tilapia (Oreochromis sp.). Feeding trial was conducted for 12 weeks in a completely randomized design with five replications (3 treatments × 5 replicates × 30 fish per tanks). The fishes weighed ±31g were fed with isonitrogenous (32%CP) and isocaloric (13MJ/kg) diets containing moringa meal at the inclusion of 0%, 10% and 15%. The results showed that, during 12 weeks trial, there was no significant difference (p>0.05) observed on growth performance among treatments despite numerical increase in body weight ranged between 93.84 to 104.41 g. Meanwhile, it was found that the feed utilization was significantly affected by the feed given. The feed utilization of 10% moringa leaf meal was not significantly different to the control. The feed conversion ratio (FCR) recorded for the control, 10% and 15% of moringa leaf meal inclusion were 1.33±0.12, 1.44±0.13 and 1.75±0.15, respectively. The body composition also was not significantly different among treatments (p>0.05). The protein content of fish muscle ranged between 74.39±4.14 and 81.66±4.58%. In conclusion, moringa leaf meal could be incorporated in juvenile red hybrid tilapia diet with an optimum of 10% inclusion without any adverse effect on growth performance, feed utilization and body composition.
