Abstract
This study was conducted to examine effects of feeding dry TMR(DTMR), wet TMR(WTMR) and fermented TMR(FTMR) on rumen fermentation, enzyme activity and digestibility in the total tract of sheep. Three rumen cannulated sheep were used in a 3${\times}$3 latin square design. The present results showed that pH, NH3-N, total and individual VFA, A/P ratio and enzymes (CMCase, Xylanase and Protease) activity in the rumen were higher in WTMR and FTMR compared with DTMR. In addition, dry matter, organic matter, crude protein, ether extract, NDF and ADF digestibility in the total tract were also higher in WTMR and FTMR compared with DTMR. Therefore, the present results showed that WTMR and FTMR are better than DTMR for rumen fermentation and nutrients digestibility.
