摘要
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 33 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.

本研究旨在研究饲喂干燥TMR（DTMR），湿TMR（WTMR）和发酵TMR（FTMR）对瘤胃瘤胃发酵，酶活性和消化率的影响。三个瘤胃插管绵羊用于33拉丁方设计。结果表明，与DTMR相比，WTMR和FTMR中瘤胃的pH，NH3-N，总VCC和个体VFA，A / P比和酶（CMCase，木聚糖酶和蛋白酶）活性均较高。此外，与DTMR相比，WTMR和FTMR中总干道中的干物质，有机物，粗蛋白，乙醚提取物，NDF和ADF消化率也更高。因此，目前的结果表明，WTMR和FTMR优于DTMR对瘤胃发酵和养分消化率的影响。
