1.通过测定小麦戊聚糖对肉仔鸡肠道菌群和血液黏度的影响，探讨了小麦戊聚糖抗营养作用的机理.采用碱法提取小麦戊聚糖，经胰酶、α-淀粉酶和地衣多糖酶处理，高速离心分离纯化。使用β-木聚糖酶解聚一些戊聚糖，这将多糖的相对粘度降低4倍。添加35 g碱提取戊聚糖（含阿拉伯聚糖854 g/kg DM）显著（P
1. The mechanism of the anti-nutritive activity of isolated wheat pentosans was investigated by examining the roles of digesta viscosity and gut microflora in broiler chickens.2. Wheat pentosans were isolated by alkaline extraction and purified by sequential treatment with pancreatin, alpha-amylase and lichenase, and high-speed centrifugation. Some of the pentosans were depolymerised using a beta-xylanase, which reduced the relative viscosity of the polysaccharides 4 fold.3. Inclusion of 35 g alkali-extractable pentosans (containing 854 g arabinoxylans/kg DM) per kg diet significantly (P
