The effect of partial replacement of Groundnut Cake with Cassava Leaf Meal (CLM) with or without enzyme supplementation on the performance of broiler starter chicks was investigated. This study was undertaken at the University Teaching and Research Farm, Animal section, Faculty of Agriculture, University of Abuja. The site has latitude 8.55°N and 90°N; longitude 7° 00°N and 7° 05°E. It covers land mass total of 655qkm (6, 500 hectare). One hundred and ninety-four (194) day old white marshal broiler starter chicks purchased from a reputable hatchery was used in the study which lasted for five (5) weeks. It was a 3x2 factorial arrangement in a Completely Randomized Design (CRD). There were eight (8) treatments with three replicates and eight (8) birds per replicate. Feed and water were supplied adlibitum while other poultry management procedures were strictly adhered to. There were significant effects (p<0.05) of the treatment on the daily weight gain, which are 39.02g, 34.81g, 34.38g and 24.76g at 0%, 20%, 40% and 60% CLM inclusion levels respectively. The daily weight gain decreased as the level of Cassava leaf meal increased from 0% to 60%. The dietary treatment also had significant effects (p<0.05) on the feed to gain ratio. Apart from the control diet, treatment 2 had a good feed to gain ratio compared to other treatments. Values recorded were 2.69, 2.79, 2.63, and 2.90 at 0%, 20%, 40% and 60% inclusion levels.respectively. Generally, the results of the experiment showed that the ingredients were not toxic, hence, could be introduced to broiler starter chicks between the ranges of 20% and 40% inclusion which gave promising result when compared to 60% inclusion. Cassava Leaf Meal is seen to be a promising feed ingredient obtained at lesser price when it is well processed. It is not harmful to broiler chicken when given at a low level and it gives satisfactory results but depress broiler performance at higher inclusion levels.
