Effect of Bacillus licheniformis on broiler aged 0-3 weeks

【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(P0.05);Bacillus licheniformis could improve GLU level of 3 weeks broilers(P0.05);And bacillus licheniformis could significantly decrease E.coli of feces(P0.01).【Conclusion】 Bacillus licheniformis could improve performance and decrease E.coli of feces.
