| [目的]研究耐制粒(制粒条件0。1 MPa,65 ℃)地衣芽孢杆菌对0～3周龄肉仔鸡生产性能、血液生化指标和粪便大肠杆菌数的影响。[方法] 将自制地衣芽孢杆菌粉剂,按3 g/kg添加量与1～21日龄肉仔鸡无抗生素日粮混合,于0。1 MPa、65 ℃条件下制成试验颗粒料饲喂AA肉仔鸡,试验为期3周,探讨耐制粒地衣芽孢杆菌对肉仔鸡生产性能、血液生化指标和粪便大肠杆菌数的影响。[结果] 与对照组相比,地衣芽孢杆菌可极显著降低1周龄肉仔鸡的平均采食量(P<0。01),显著提高3周龄肉仔鸡的血糖(GLU)水平(P<0。05),显著降低肠道大肠杆菌数(P<0。01)。地衣芽孢菌对肉仔鸡其他生产和血液生化指标无显著影响。[结论] 地衣芽孢杆菌对提高雏鸡的生产性能、降低肠道大肠杆菌具有一定的促进作用,可提高3周龄肉仔鸡血糖含量,而对所测其他生产和血清生化指标无显著影响。 |

| Abstract: |
| 【Objective】 An experiment was conducted using a total of 96 day-old Arbor Acres broilers to investigate the effects of Bacillus licheniformis on performance,blood biochemical indexes and E.coli of feces during 0-3 weeks of age.【Method】 Bacillus licheniformis were mixed with 1-21 days feed at supplement amount 3 g/kg and were pelleted under the condition of 0.1 MPa,65 ℃,which were used to study the effects of Bacillus licheniformis on performance,blood biochemical indexes and E.coli of feces during 0-3 weeks of age.【Result】 The result showed that: Bacillus licheniformis could decrease ADFI of 1 week broilers (P>0.05);Bacillus licheniformis could improve GLU level of 3 weeks broilers(P<0.05);And bacillus licheniformis could significantly decrease E.coli of feces (P<0.01).【Conclusion】 Bacillus licheniformis could improve performance and decrease E.coli of feces. |
