Integrative multi-omics analysis demonstrates dietary fibre influences caecal microbiota in chickens, highlighting gut health implications.
Background The sustainability of poultry farming faces significant challenges due to rising feed costs and competition with human food sources. Dietary fibre offers a promising, cost-effective alternative due to its beneficial impact on gut health. We utilised a multi-omics approach to understand the influence of soluble inulin and insoluble cellulose dietary fibres on the composition and function of caecal microbiota in broilers. Results High inulin significantly altered caecal microbial composition and promoted broader microbial metabolic adaptations, while high cellulose had a minimal impact. Conclusions These findings will enhance our understanding of how various fibre types and quantities shape gut microbiota, ultimately leading to improved poultry performance.
