Precision Glycan Supplementation Improves Gut Microbiota Diversity, Performance, and Disease Outbreak Resistance in Broiler Chickens

The intensive poultry production system faces production challenges like pathogenic infections, poor performance, and bird welfare. The use of antibiotics has been reduced due to regulations and increasing antimicrobial resistance, promoting research into viable alternatives. Precision glycans represent an alternative that modulates the gut microbial community and its metabolic functions. This study compares birds fed precision glycan-supplemented and non-supplemented diets in a commercial broiler farm. We report major alterations in microbiota across caecum, ileum, and ileum mucosa gut sections. The treated birds also showed better intestinal morphology and higher weight gain with an improvement in feed efficiency and disease resistance.
