木聚糖酶;小麦型日粮;器官指数;黄羽肉鸡;组合酶
摘  要：
通过对21日龄黄羽肉鸡器官指数和胃蛋白酶、胰蛋白酶、胰脂肪酶、胰淀粉酶以及血清中木糖水平进行检测,研究酶制剂对动物内脏器官所产生的影响,以及组合酶和单酶之间的差异。木聚糖酶在小麦型日粮中添加,降低了肝脏、肌胃、腺胃、十二指肠、空肠和回肠的器官指数,增加了胰腺的器官指数;降低了胃蛋白酶和胰蛋白酶的分泌水平;组合酶比单酶降低小肠器官指数更明显,单酶增加了胰脂肪酶的分泌水平,组合酶降低了胰脂肪酶的分泌水平,差异不显著(P>0.05)。小麦型日粮饲喂组血清中木糖的水平高于玉米型日粮组和加酶组,酶制剂的添加降低了血液中的木糖水平,各处理组之间差异不显著(P>0.05)。

摘  要：
This study was conducted to evaluate effects on animal organ and the difference between single xylanase and combinative xylanase by measuring organ index,secretion level of pepsin,trypsin,lipase and amylase and xylose in serum of 21-day Yellow-feather broiler.The indexes of liver,gizzard,glandular stomach,duodenum,jejunum and ileum were decreased and the pancreas index was increased with xylanase addtion in wheat-soybean meal diet.Moreover,the secretion levels of pepsin and trypsin were enhanced with xylanase supplementation.In addition,small intestine index was lowered with xylanase cocktail addtion than single xylanase.The secretion of lipase was enhanced with single xylanase supplementation than combinative xylanase.However,no difference was observed.The level of xylose in serum was increased when corn was replaced by wheat as engergy feed,which was lowered with xylanase supplementation. There was no difference among different treatments.
