| Abstract | ||
| This work was conducted to study the effect of microbial treatment (MT) using fungi Plearotus ostreatus on the chemical composition in vitro Dry Matter Digestibility (DMD) and Organic Matter Digestibility (OMD) for barley straw grounded or chopped using four levels of moisture (0 , 20 , 40 and 60% ). And four incubation periods ( 0 , 2 , 4 and 6 weeks ) at four degrees of temperatures ( 0 , 20 , 30 and 40 0c ) .MT of ground and chopped barley straw using P.ostreatus reduced (P<0.01) the amount of NDF , ADF , hemcellulose , lignin and phenolic compound concentration as compared with untreated . However , MT increased (P<0.01) dry and organic matter contents , cellulose and in vitro dry and organic matter digestibility’s , activity of laccase enzyme and number of anaerobic bacteria as compared with untreated .Physical shape of barley straw ( chopped or grounded ) had no effect on microbial treatment.However ,the results indicated highly significant interaction ( P< 0.01) for moisture % and degrees of temperatures and incubation periods for chopped and ground barley straw on microbial treatment | ||
