Study of utilization of moringa (Moringa oleifera Lam.) leaf on growth performance and protein digestibility in Tilapia (Oreochromis niloticus L.) was conducted. Diets were prepared by supplementing with moringa leaf at 0, 5, 10 and 15 percent, all diets contained 25 percent crude protein and isocaloric diets of 2,500 kcal/kg. In this experiment, tilapia with initial weight of 27.06+-0.97 g/fish was fed with experimental diets for 60 days. The result showed that growth performance was similar in all groups (p GT 0.05), average daily weight gain was 1.21+-0.39, 1.27+-0.13, 1.29+-0.19 and 1.07+-0.16 /fish/day, respectively. Feed conversion ratio was 1.29+-0.58, 1.08+-0.12, 1.08+-0.16 and 1.27+-0.22, respectively, and protein efficiency ratio was 0.33+-0.04, 0.37+-0.04, 0.37+-0.04 and 0.36+-0.03. Digestibility coefficiency and protein digestibility in fish fed with diets supplemented with moringa leaf were not significantly different (p GT 0.05). The digestibility coefficiency and protein digestibility were found in range of 51.66-58.42 percent and 68.53-74.86 percent respectively. In the part of fish health found that, hematological parameters were not significantly different (p GT 0.05), and pathology of liver was similarly in all groups. Therefore, supplementing moringa leaf with 10 percent in diet showed no adversed effect on growth, protein digestibility and fish health.
