An experiment was carried out to investigate the effect of substituting Moringa oleifera leaf meal (MOLM) for sunflower seed meal (SSM) as a protein source of egg strain commercial chickens. The effects of substitution on feed intake (FI), dry matter intake (DMI), egg weight (EWT), Laying percentage (LP), egg mass production (EMP), and feed conversion ratio (KG FEED/KG EGGS) were investigated. Four dietary treatments based on MOLM and SSM as plant protein sources were formulated such that MOLM reciprocally replaced SSM at levels of 20, 15, 10 and 0% giving the dietary treatments containing 0, 5, 10 and 20% MOLM levels for MOLM-0, MOLM-10, MOLM-15 and MOLM-20 respectively. A total of 96 twenty-one weeks of age pullets were allocated to the dietary treatments in a randomised design. Each treatment consisted of three replicates and eight birds per replicate. The EWT was significantly highest in MOLM-0 and lowest in MOLM-10. LP showed a significant progressive decreasing trend as MOLM proportion increased in the diet. Further, EMP showed a significant progressive decrease at 10 and 20% MOLM levels. DMI and DFI significantly increased progressively at 10 and 20% MOLM levels. Also, Kg feed/Kg eggs (g feed intake/g egg mass) were significantly highest in birds fed 20% MOLM levels. The results, therefore, suggest that MOLM could completely replace SSC up to 20% without any detrimental effect in laying chickens. However, for better efficiency 10% inclusion level is optimal and an addition of MOLM above 10% high energy based feeds are required for better utilization.
