The purpose of this study was to examine the effect of giving Moringa leaf flour and “katuk” leafs and their combination on the performance of broiler chickens. The study used 96 DOC broiler chickens and Completely Randomized Design [CRD] with 4 treatments and 6 replications; each unit consists of 4 chickens. The treatments consisted of: R0: Basal ration [control], R1: Basal ration + 10% Moringa leaf meal, R2: Basal ration + 10% katuk leaf meal and R3: Basal ration + a combination of 5% Moringa and katuk leaf meal. The variables measured included feed intake, body weight gain and feed conversion ratio. The results of the analysis of variance showed that the treatment had a very significant effect [P<0.01] on all measured variables. It was concluded that the administration of 10% Moringa leaf meal, 10% katuk leaf meal and a combination of 5% of these two herbal meal decreased the performance of broiler chickens and tend to increase income offer feed cost [IOFC].
