Effect of Bacillus species-fermented products and essential oils on growth performance, gut morphology, cecal short-chain fatty acid levels, and microbiota community in broilers.

ABSTRACT: In this study, the effects of Bacillus species-fermented products (synbiotics [SYNs]) and essential oils (EOs) on the growth performance, gut morphology, cecal short-chain fatty acid (SCFA) levels, and microbiota of broilers were investigated. A total of 180 one-day-old unsexed broiler chicks (Ross 308) were randomly assigned to 5 dietary treatments as follows: basal diet (control group), basal diet plus enramycin (10 mg/kg; A group), basal diet plus SYNs (3 × 10¹¹ CFU spore/kg of feed; SYN group), basal diet plus EOs (100 mg/kg; EO group), and basal diet plus SYNs and EOs (SYN + EO group), with 6 replicate cages per treatment group and 6 birds per cage. The SYN+EO treatment resulted in a higher (P = 0.003) average daily gain at 1 to 14 d of age than did the control and EO treat
