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>0.05),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>0.05);添加0.1%和0.2%木聚糖酶时能降低肝脏指数(P>0.05);添加0.3%木聚糖酶时能降低胰腺指数(P>0.05)。(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<0.01),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<0.05),为最适添加量。
108 geese aged one day were randomly divided into 6 groups. Geese in different groups were fed with diet bas corn, wheat and wheat with different concentration xylanase respectively. The results showed that the diets with 0.2%、0.3% xylanase could decrease the indices of stomach and duodenum, and the indices of stomach and duodenum of geese fed with 0.2% xylanase added to diet were lower than those fed with diet based on corn. 0.3% xylanase added to diet could decrease the indices of jejunum, ileum and cecum. 0.1%、0.2% xylanase added to diet could decrease the indices of liver. 0.3% xylanase to diet could decrease the indices of pancreas. Compared with diet based on wheat, 0.2% xylanase added to diet has wheat could improve the protease activity by 34.38% (extremely P〈O.O1) and 0.1% xylanase added to diet based on wheat improve the amylase activity by 20.57% significantly.
