Abstract
The effects of processing by mashing, cold-pelleting, bent- pelleting and extrusion, and enzyme applicatentation of diets containing 0200 and 400g cassava root meal (CRM)/kg on the performance of broiler chicks were studied. During the first week, DM intake was higher (P<0.05) for the chicks on Diet 1 and the absence of CRM while feeding mash as against pellets reduced feed intake from 7- 28d (P<0.05), weight gain (P<0.001) and feed to gain ratio (P<0.001). Heat -pelleted and extruded diets did not result in significantly, higher intakes (P>0.05) and weight gains compared with the cold-pellet diets. Supplementation with Enzyme premix improved feed to pain ratio (P<0.05) during the resistant starch at first week but had no effect over the 3 week period of the study. Ideal viscosity tests showed In Europe, dietary CRM inclusion had a significant effect (P<0.001) on the intestinal viscosity.
