Gut transcriptional response of broiler chickens fed a diet supplemented with yeast cell wall extracts

In a context moving towards antibiotic-free livestock production, research in feed additives has largely increased to evaluate different products and their effects on animal health and immune response, besides animal productivity. Among the different products, prebiotics such as yeast cell wall (YCW) extracts have been widely used.The present study aimed at evaluating the effect impact of the dietary supplementation with YCW (mainly mannano-oligosaccharides and β-glucans) from Saccharomyces cerevisiae on gut whole-transcriptome profiling in broiler chickens.
