Chemical composition and in-vitro digestibility of sugarcane bagasse and rice husk treated with three strains of white rot fungi and effective microorganism

A study was conducted to evaluate the effect of biological treatments of sugarcane bagasse (SCB) and rice husk (RH) with three strains of white-rot fungi (WRF) (Pleurotusostreatus (Po), Pleurotusflorida (Pf) and Trichodermaviride (Tv) and effective microorganism (EM) on the chemical composition and in-vitro digestibility. The experiment consisted of 2x5 factorial arrangements, two levels of feed (SCB and RH) and five levels of biological treatments (Control, Po, Pf, Tv, and EM).Treatment of RH with EM, Tv, Po and Pf, significantly increased crude protein content from 7.90% in untreated to 7.92, 10.46, 10.61 and 11.35%, respectively. The corresponding increase in CP% of sugarcane from 2.61% was 3.41, 5.96, 5.89 and 5.95%.Treatments significantly (P<0.001) decreased neutral detergent fiber, acid detergent fiber, acid detergent lignin cellulose and hemicelluloses contents with the lowest value recorded for Tv. The IVOMD, IVDMD and metabolizable energy (ME) were significantly (P<0.001) increased. In conclusion, the study indicates that treatment of RH with Trichodermaviride and SCB with EM is more effective than others in improving the nutritive value of the roughages. We suggest evaluation of the treated roughages on animal performance.
