dc.description.abstractCARBOHYDRATES FROM LIGNOCELLULOSIC FEED CAN BE RELEASED BY BASIDIOMYCETE FUNGI FOR RUMINAL FERMENTATION. THIS STUDY AIMED TO EVALUATE THE BIOCONVERSION OF HAY OF RYEGRASS-FESCUE (LOLIUM PERENNE?FESTUCA ARUNDINÁCEA) BY SOLID STATE FERMENTATION WITH PLEUROTUS OSTREATUS, TO OBTAIN SUPERIOR QUALITY HAY. AFTER ONLY 14 DAYS OF FERMENTATION, CRUDE PROTEIN (CP) (4.73 TO 5.16%), AND NON-FIBROUS CARBOHYDRATES (NFC) (20.84 TO 25.04%) INCREASED, WHILE NEUTRAL DETERGENT FIBER (NDF) (68.72 TO 64.87%) AND ACID DETERGENT LIGNIN (5.88 TO 1.98%) DECREASED. THE ENZYMATIC BIODEGRADATION CARRIED OUT BY P. OSTREATUS WAS VERIFIED, THROUGH MEASUREMENTS OF ENZYMATIC ACTIVITY. LIGNIN PEROXIDASE (LIP) AND LACCASE (LAC) REACHED THE HIGHER ACTIVITY ON DAY 14 (19.51 U/L AND 34.17 U/L, RESPECTIVELY), WHEREAS MANGANESE PEROXIDASE (MNP) DISPLAYED STABILITY UP TO 21 DAYS OF FERMENTATION (BETWEEN 6.54 AND 7.75 U/L). IN CONCLUSION, RESULTS INDICATE THAT LIGNOCELLULOSIC FEED BIOCONVERSION BY P. OSTREATUS IS PROMISING TO IMPROVE THE RUMINAL FERMENTATION OF FIBROUS FEEDSTOCKS AND 14 DAYS WERE CONSIDERED TO BE OPTIMAL FOR HAY FERMENTATION.
