| Abstract |
White-rot fungi, a promising group of Basidiomycetes, have the ability to degrade the major components of lignocellulosic materials such as cellulose, hemicellulose and lignin. Each of three strains of this groups named, Coriolus versicolor, Pleurotus ostraetus and phanerochaete chrysosporium, was propagated in solid-state culture (SSC) individually on cotton stalks for 8weeks. Chemical analyses were carried out before and after the biological treatments. Crude protein reached to 10.3, 8.8 and 8.9% at the end of SSC for the previous fungi, respectively, versus 3.8% in the initial residue. Digestibility trials on Ossimi rams were performed using the biological treated cotton stalks as compared with the untreated residue as a control. The results revealed the experimental rams accepted the treated roughage by nearly the same ratio as when they were fed the untreated residue. The digestion coefficients of both dry matter and crude protein were elevated than control. The nutritive value as total digestible nutrients and digestible crude protein were significantly increased than the untreated residue. The nitrogen balance (g/d) ranged from 4.02 for phanerochaete chrysosporium to 6.77 pleurotus ostreatus while the nitrogen balance of untreated residue was 0.63. despite the increase of digestion coefficient for crude protein and increase of nitrogen balance, the ammonia nitrogen in the rumen was stable for the treated and untreated residue. The blood metabolite tests were in the range of normal values.
