Abstract
This work was carried out to study the effects of replacing the basal diet of Nile tilapia fingerlings by grading levels of Moringa oleifera leaves (MOL) on growth performance and body composition. One hundred and fifty Oreochromis niloticus fingerlings with an average weight of 10.84 ± 0.12g were divided into five experimental groups (30 per group). Each fish group had three equal replicates (10 per each). MOL was used at five levels 0, 5, 10, 15, and 20% instead of the basal diet. The experimental period persisted for 10 weeks. The results showed that fish body weight, body weight gain, feed intake and feed conversion ratio did not significantly differ between Tilapia fed the basal diet and 5% MOL. While, significant (P≤0.05) decreases in growth indices occurred in the Tilapia group fed diet contain 10, 15 and 20% MOL. The survival rate was 90% for Tilapia fed 0, 10, 15, and 20% MOL compared to 93.33% for fed 5% MOL. The hazard components (ammonia and nitrite) in water decreased significantly (P<0.05) with MOL. In comparison with the control group, the chemical composition of the Tilapia body showed increases in OM, NFE and EE in 5% MOL Tilapia group, while contents of CP and ash were significantly elevated with 10 and 20% MOL Tilapia groups. The condition factor, hepatosomatic index and intestinal somatic index) did not significantly differ between Tilapia fed 5% MOL and control. The MOL did not affect the condition factor. The results showed that replacing 5% of the basal diet with MOL did not negatively affect growth performance and body composition, but improved water quality and survivability.
