摘　　要：测定了河南省9个主栽小麦品种豫麦49号、豫麦47号、高优503、郑麦9023、豫麦34号、皖麦38、豫麦70号、孟12和河北8901的戊聚糖含量,结果表明,9个品种的戊聚糖含量为6 25%～8 23%;选取两个有代表性的品种豫麦70号和豫麦49号,用64只小公鸡进行代谢试验,评定添加1 2‰木聚糖酶对鸡表观代谢能(AME)值和养分消化率的影响。This study include two experiments.In experiment No.1,the content of pentosan in 9 wheat cultivars was determined in 1999-2000.Significant differences were found in pentosan content of different cultivars,ranging from 6.25% to 8.23%.In experiment No.2,the bioassay of 64 cocks was used to describe the AME and nutrient ingredient digestibility of two wheat cultivars with or without an commercial enzyme (mainly xylanase).
