Abstract

This trial was conducted to examine the influence of replacing basal diet of Nile tilapia fingerlings at different levels by Moringa oleifera leaves (MOL). Five diets were formulated which contain MOL levels 0, 5, 10, 15 and 20% instead of fish basal diet. Using MOL instead of basal diet at 5% level indicated remarkable (p≤0.05) decline fish body weight, weight gain, specific growth rate and relative growth rate. The mortality rate was 10% for fish-fed diets 0, 10, 15 and 20% MOL in compared to 6.67 for fish-fed 5% MOL. The feed intake and feed conversion ratio were significantly (P≤0.05) decrease in fish- group fed diets 3, 4 and 5 in compared to fish-fed diets 1 and 2. The blood parameters results showed that the total protein and globulin increased (P≤0.05) in all levels of MOL on the other hand, the creatinine and uric acid were significantly decreased. The protease, lipase and amylase activities were significantly reduced (P≤0.05) by 10, 15 and 20% MOL. Meanwhile, the blood liver function enzymes (AST and ALT) activities decreased (P≤0.05) at 5% MOL level in comparison with control and other groups of MOL. The antioxidant parameters including glutathione, total antioxidant capacity and superoxide dismutase increased (P≤0.05) by all levels of MOL. In conclusion, The results obtained indicated that using MOL instead of the basal diet at 5% had no significant effect on the growth performance and health status of Nile tilapia fish.
