摘　　要：试验选取1日龄朝鲜龙城鹌鹑108只，研究小麦-豆粕型基础日粮添加木聚糖酶对鹌鹑生长性能及免疫性能的影响。试验鹌鹑按体重随机分为3个处理组，每个处理设3个重复，每重复12只。第1组设为对照，饲喂玉米-豆粕型基础日粮；第2组饲喂小麦-豆粕型基础日粮；第3组在小麦-豆粕型日粮中添加2000U／kg的木聚糖酶，试验期42d。结果表明：小麦日粮对育雏期（0-21日龄）鹌鹑生长性能无显著影响（P〉0．05），但是显著降低育成期（22-42日龄）鹌鹑的体重和日增重（P〈0．05）。小麦日粮中添加木聚糖酶2000U／kg，对鹌鹑的生长性能无显著影响（P〉0．05）。小麦日粮组的新城疫抗体效价显著低于玉米对照组（P〈0．05），但是小麦日粮可以显著提高细胞免疫水平（P〈0．05）。添加木聚糖酶对鹌鹑的免疫性能无显著影响（P〉0．05）。This experiment was conducted to study the effects of xylanase added in wheat-basal diet on growth performance and immune properties of quails. A total of 1081-day-old quails were randomly assigned to three groups with 3 replicates of 12 quails each. Birds in the control group were supplied with corn-basal diet, the second group was supplied with wheat-basal diet and the third group was supplied with the same diet added xylanase. The experiment last for 42 days. The result showed that （1） Wheat -basal diet had no significant effect during 0-21 d, but could obviously decrease body weight and average daily intake of quails （P 〈 0.05）; （2）Wheat diet added 2000 U/kg xylanase had no significant effect on growth performance of quails （P 〉 0.05）; （3）in the NDV HI antibody titers in the were significantly lower than those of control group （P 〈 0.05）, but cell-mediated immunity of quails was increased （P 〈 0.05）; （5）Wheat- basal diet added xylanase had no significant effect on immunity of quails（P 〉 0.05）.
