In: Egyptian Journal of Nutrition and Feeds 2003.v6 (2)Summary: Four low quality roughages, namely banana waste, com stalks, rice straw and wheat straw, were subjected to biological treatment under solid state fennentation by Trichoderma viride (F-516), Penicillium funiculosium (629) and Saccharomyces cerevisiae (AFZ-98). The biological treatments resulted in significant (P<O.OI) increases in dry matter and crude protein contents as well as in vitro dry matter and organic matter disappearances (IVDMD and IVOMD). On the other hand, a significant decrease in crude fiber (CF) content (P<O.Ol) was recorded. Fungal treatments decreased hemicellulose and cellulose contents in all wastes used (P<O.OI). The biologically treated banana waste achieved the highest values for organic matter (OM), ether extract (EE) and nitrogen free extract (NFE) contents as well as IVDMD and IVOMD.
