| 中文摘要: |
| 研究了枯草芽孢杆菌(Bacillus subtilis) J-11 菌剂对肉鸡肠道5 种消化酶活力及生长性能的影响。选用3
日龄仔肉鸡2 000 只，平均随机分成两组，即对照组和添加组。添加组3~21 日龄期间在基础日粮中添加0.1%J-11 菌
剂，对照组不添加J-11 菌剂。结果表明，饲料中添加0.1% J-11 菌剂后，可使肉鸡粪便中琢-淀粉酶、蛋白酶、脂肪酶
和纤维素酶的平均酶活力分别提高44.02%、45.99%、58.37%和45.73%，茁-葡聚糖酶的活力无显著变化；肉鸡平均日
增重提高13.00%，料重比降低11.0%。停饲J-11 菌剂后，添加组粪便中消化酶活力和肉鸡平均日增重等指标逐渐接
近对照组。J-11 菌剂具有提高肉鸡肠道多种消化酶活力，增加饲料转化率，改善肉鸡生长性能的作用。 |
| 英文摘要: |
| Effects of Bacillus subtilis J-11 preparation on five kinds of digestive enzyme activity in intestinal tract and
growth performance of broiler were studied. 2000 three-day-old broilers were divided into test group (supplemented with
0.1% J-11 preparation from 3 days old to 21 days old) and control group (fed by the basal diet) on the average. The results
showed that 琢-amylase, protease, lipease, cellulase activity in broiler manure increased by 44.02%, 45.99%, 58.37%,
45.73%, respectively, while 茁-gluanase activity was not different. Broiler weight increased by 13.0%, feed to gain ratio
decreased by 11%. When J-11 preparation was stopped feeding those indices of test group were close to those of control
group gradually. J-11 preparation can improve some intestinal digestive enzyme activity in intestinal tract and growth
performance of broiler. |
