ABSTRACT

An experiment was conducted to investigate the effects of using two different

enzyme substrates on the performance of broilers fed peeled cassava root

meal (PCRM), in a 3 x 3 factorial arrangement in a completely randomised

design experiment. One hundred and eighty-nine broiler chicks aged 14 days

were assigned to nine experimental diets where PCRM replaced maize at 0,

50 and 75 percent levels. The diets were formulated to be roughly

isonitrogenous and isoenergetic containing starter (15-36 days; 24% CP,

2800 Kcal/kg-1 ME) and finisher (37-58 days; 21% CP, 2800 Kcal/kg-1 ME)

and 200ppm of enzyme (Nutrase xyla and Roxazyme G) were added to the

diets. Results indicated that Nutrase xyla and Roxazyme G supplementation

increased ADFI in the starter and finisher phases at all levels of PCRM
