The role of oligosaccharides and polysaccharides of xylan and mannan in gut health of monogastric animals

Thanks Dr. Fiodor S. Marchenkov, “I agree that it is imperative to look at ingredients. You are correct that xylans and mannans are not the only NSPs, however, they are the most abundant hemicellulosic polysaccharides (a major focus of this article). xylans alone make up 43% while beta-glucans are only 2%. Beta-glucan have a high molecular weight compared to xylan, however are easily broken down because of their high soluble property. The structure of xylan varies with the ingredients used and so does their solubility which directly influences the debranching mechanism (through enzyme supplementation). It is imperative when choosing an enzyme strategy to look at what will give you the highest impact in the feed. That includes as you said the local sources and regional specific ingredients. However, in a typical diet xylans are the largest targets to create the most impact.”
