| 摘 要： | 试验选用1日龄健康肉用雏鹅108只，随机分为6组，分别饲喂玉米型饲粮、小麦型饲粮以及在小麦饲粮中添加不同浓度木聚糖酶的饲粮。结果表明：（1）小麦饲粮中添加0.2％和0.3％木聚糖酶能降低胃及十二指肠指数（P〉O．05）,添加量为0．2％时低于玉米组水平，添加0.3％木聚糖酶能降低空回肠及盲肠指数（P〉O．05）；添加0．1％和0．2％木聚糖酶时能降低肝脏指数（P〉O．05）,添加0.3％木聚糖酶时能降低胰腺指数（P〉O．05）。（2）在小麦饲粮中添加木聚糖酶能够改善肉鹅蛋白酶活性,添加量为0．2％时比小麦对照组高出34．38％（P〈O．01），效果最佳；木聚糖酶的添加同样能够改善肉鹅淀粉酶的活性，添加量为0．1％时比小麦对照组高出20.57％（P〈O．05），为最适添加量。
