In order to evaluate the nutritive value of extrusion processed mixture of cassava pulp and urea (Capsurea), gas production characteristics from the fermentation of Caspurea vis-a-vis control (soybean meal, SBM) were measured at 1 to 96 h using in vitro gas production technique adapted to describe the kinetics of fermentation. Results revealed that the mean gas production was significantly (P≤0.01) hiher in Capsurea than control. The rapidly soluble fractions of DM and OM were higher (P≤0.05) in Caspurea than the control at 3 to 12 h post incubation. The potentially degradable fraction (b) of DM and OM did not differ (P≥0.05) significantly. Ammonia concentrations from the fermentation of the insoluble N fraction of Caspurea and Control were significantly (P≤0.01) different. It is concluded that the cassava pulp based product Capsurea has improved potential for use as a ruminant feed.
