A preliminary study investigated the impact of commercial feed dilution with copra meal (CM) or cassava leaf meal (CLM) and enzyme supplementation on broiler performance. Commercial feed alone (control) or diluted with CM and CLM at a concentration of 100 and 200 g/kg in the starter and finisher diets, respectively, was fed without and with Challenzyme 300A at a concentration of 300 g/tonne in 2 × 2 factorial arrangements with a control. Two hundred, 7-day-old male, Cobb 500 broiler chicks were randomly assigned to 5 diets containing 4 replicates of 10 birds each. There were no interaction or main effects (P > 0.05) on feed intake during either the starter or finisher phase. In the starter phase, feed-to-gain ratio (F:G) increased (P 0.05) on weight gain (WG) in the starter phase. Diluting the feed with CM or CLM without enzyme suppressed (P 0.05) on the carcass traits. Enzyme supplementation reduced (P 0.05) between the control and CM groups and between the fiber sources. The results suggest that dilution of commercial diet with CM or CLM may be a viable option for medium- and small-scale broiler production in the region. There is need for more research in the level of dilution, enzyme source, and concentration.
