Antibiotic growth promoters (AGPs) have been used for decades in animal production to improve animal productivity and health. However, the global concern about development and transference of antimicrobial resistance from animal production had encourage the development of alternatives to AGPs. The information about the effects of phytogenic compounds on chicken intestinal microbiota is required to understand the potential of these bioactive natural products as alternatives to antibiotics. Therefore, the aim of this study was to evaluate and compare the impact of a blend of chestnut and quebracho tannins against antibiotics feed additives on chicken gut microbiota using high-throughput sequencing of 16S rRNA gene amplicons under experimental and commercial conditions.
