Comparing the Potential of Bacillus amyloliquefaciens CGMCC18230 with Antimicrobial Growth Promotors as a Broiler Feed Supplement for Growth, Bone Development, Expression of Phosphorus Transporters, and Excreta Microbiota

Bone health of broiler chickens is essential for welfare and production. In this study, the probiotic Bacillus amyloliquefaciens (BA) CGMCC18230 was compared with antimicrobial growth promoters (AGPs), for its ability to promote growth and bone health. the alpha diversity of the AGPs tended to decrease on the day 42 but increased in the BA group. Beta-diversity also showed significant responses with increased abundance of Christensenellaceae, and Peptococcaceae in the BA group .
