Since antibiotic resistance is a global health issues, the use of antibiotics in animal feed for growth promotion has been restricted in many countries. Bacillus licheniformis probiotic is a potential alternative to antibiotics for increasing poultry performance. Through metagenomic sequencing, this study investigated the effects of B. licheniformis-fermented products (BLFPs) and enramycin on the microbial community composition and antibiotic resistance gene (ARG) distribution in the cecal digesta of broilers at the age of 35 d. In total, 144 one-day-old male broiler chicks (Ross 308) were randomly assigned to 4 dietary treatments as follows: basal diet (control [C] group), basal diet plus 10 mg/kg enramycin (E group), basal diet plus 1 g/kg BLFPs (L group), and basal diet plus 3 g/kg BLFPs (H group), with 6 replicate cages per treatment group and 6 birds per cage. The results indicated that the cecal alpha diversity (richness and evenness) of bacterial species was higher in the H group than in the C group. Principal coordinate analysis of microbiota and the ARG composition indicated clear differences among the cecal samples of the groups. In the cecal digesta, the abundance of active bacteria associated with probiotic properties, such as Lactobacillus crispatus and Akkermansia muciniphila, was higher in the H group than in the other groups. Enramycin treatment promoted the expression of peptide (bcrA), glycopeptide (vanRI), and lincosamide (lsaE) resistance genes but inhibited the expression of aminocoumarin (parY) and pleuromutilin (TaeA) resistance genes. BLFP (1 and 3 g/kg) treatment suppressed the expression of aminoglycoside (ANT(6)-Ib), streptogramin (vatB), and peptide (ugd) resistance genes but enhanced the expression of macrolide (efrA) and aminocoumarin (novA) resistance genes. The abundance of peptide resistance genes in Bacteroides spp. was lower in the H group than in the C group. The abundance of lincosamide resistance genes in Lactobacillus spp. was higher in the E group than in the other groups. These results demonstrated that differential changes in the structure of 3 g/kg BLFPs and enramycin-induced cecal microbial communities accompany changes in the abundance of bacterial hosts carrying specific ARGs in the cecal microbiota of broilers.
