Chemical composition, in sacco rumen disappearance of various cell wall constituents (CWC) and in vitro fermentation pattern of hydrothermally treated (1 to 14 kp/cm2 pressure for 5 min) rice straw was examined. At 10 kp/cm2 pressure treatment (maximum effect) the contents of dry matter (DM), organic matter (OM), neutral detergent fibre (NDF), acid detergent fibre (ADF), hemicellulose (HC) and cellulose (CE) were decreased by 32.5, 35.3, 27.8, 10.2, 61.2 and 25.1%, respectively (P < 0.05), over the untreated control. The in sacco rumen disappearance of DM, OM, HC and CE from rice straw treated at 8 kp/cm2 pressure (maximum effect) and incubated for 48 h was increased from 53.2 to 77.7, 52.4 to 80.3, 49.5 to 82.0 and 49.2 to 79.3%, respectively (P < 0.01). In vitro production of total volatile fatty acids and the content of TCA-insoluble protein was also significantly higher (P < 0.05) on treated compared with untreated straw.
研究了水热处理（1至14千帕/平方厘米压力，处理5分钟）稻草的化学成分、瘤胃内各种细胞壁成分（CWC）的消失情况以及体外发酵模式。在10千帕/平方厘米压力处理（效果最佳）下，与未处理的对照相比，干物质（DM）、有机物（OM）、中性洗涤纤维（NDF）、酸性洗涤纤维（ADF）、半纤维素（HC）和纤维素（CE）的含量分别降低了32.5%、35.3%、27.8%、10.2%、61.2%和25.1%（P<0.05）。在8千帕/平方厘米压力（效果最佳）下处理并培养48小时的稻草，其瘤胃内DM、OM、HC和CE的消失率分别从53.2%提高到77.7%、52.4%提高到80.3%、49.5%提高到82.0%、49.2%提高到79.3%（P<0.01）。与未处理的稻草相比，处理后的稻草体外总挥发性脂肪酸产量和三氯乙酸不溶性蛋白含量也显著更高（P<0.05）。
