Abstract :

Studies were carried out on the degradation of rattan wood and maize stovers using Pleurotusostreatus in cultures incubated for 0-90days.The proximate composition, percentages of nitrogen, carbon and potassium, pH, loss of organic matter, loss of water, fibre content, organic matter digestibility, metabolisable energy and in-vitro gas digestibility were determined using the substrates degraded by P.ostreatus. In degraded rattan wood, crude protein increased significantly from 1.52% to 3.99% and on maize stovers 2.74% to 7.45%. Crude fibre decreased significantly from 46.05% to 20.13% for rattan wood and maize stovers from 33.25% to 15.66% after 90 days of incubation. In both substrates ether extract, ash and dry matter contents also decreased but moisture contents increased from 0-90days.Percentage of nitrogen, carbon and potassium increased with increase in incubation period. The pH decreased, the least value being 3.78. Loss of organic matter in the substrates decreased significantly as the period of incubation increased. There was also significant decrease in loss of water as the incubation period increased, the lowest being 37.25 in rattan wood. The fibre content and enzyme production decreased but the organic matter digestibility and metabolizable energy increased with increasing incubation period .Gas production for in-vitro gas digestibility increased at three hour intervals with highest volume being 28.00ml at 24hours for maize stovers.
