Abstract

Treatment with Pleurotus ostreatus strain EM-1 recently has been proposed as an effective means of transforming maize cob into nutritive animal feed for livestock production in the West African sub-region. This study compares P. ostreatus strain EM-1-treated maize cob with peels of cassava and plantain, widely-accepted comp lern entary feedstuffs in West Africa, in terms of in vitro biodegradability and composition. Subjection of milled maize cob samples to solid state fermentation by P. ostreatus strain EM-1, until complete mycelial colonization, resulted in an increase of 107.3% in cell extractives and a 41.2% reduction in lignin content. The cellulose content of the treated maize cob exceeded that of plantain peel and cassava peel by 44.9 and 71.2%, respectively, while protein and lipid content did not differ significantly from mean values obtained for cassava peel. Cellulosic sugar production from treated maize cob, measured at 37°C for up to 3 h in the presence or absence of 0.05 U mL cellulase, surpassed that of cassava peel by 52.3% (p<0.05) but was significantly lower than that of plantain peel. The data indicate that the potential metabolizable energy of P. ostreatus strain EM-l-modified maize cob far exceeds that of cassava peel. Based on the present findings, maize cob treated with P. ostreatus strain EM-1 should serve as an excellent complementaiy energy source for small ruminants in the West African sub-region. © 2011 Asian Network for Scientific Information.
