Commercial Feed Diluted with Different Fiber Sources and Enzyme Product for Broilers: Growth Performance, Carcass and Gut Health

Abstract

ABSTRACT The dilution of commercial broiler feed with copra meal (CM), palm kernel meal (PKM) and cassava leaf meal (CLM) and enzyme supplementation was investigated. Two hundred and eighty 7-day old Cobb 500 broilers were fed commercial feed alone or diluted with the test ingredients with and without enzyme. There were no interaction effects (p>0.05) on feed intake (FI) and weight gain (WG). Poorer (p0.05) by enzyme supplementation. There was no interaction effect on final body weight (FBW). Diet dilution depressed FBW (p0.05) this weight depression. Abdominal fat was lighter (p0.05) on the weight of gut segments and E. coli count. Heavier (p<0.05) liver, gizzard and intestine were observed on the test diets. Commercial feed dilution with CM, CLM and PKM at 100 g/kg for starter and 200 g/kg for finisher would be a viable option for smallholder broiler production. More research is needed into dilution levels and enzyme concentrations.
