Abstract: Supplementing poultry diets with xylanase partially depolymerizes the xylans present in the dietary cereals, reducing the number of sugars in the molecular chains. The resulting oligosaccharides can be selectively fermented by beneficial intestinal bacteria, resulting in improved nutrient utilization (De Maesschalck et al., 2015). The study aim was to investigate the production of xylo-oligosaccharides (XOS) in different batches of Australian wheat, in the presence or absence of xylanase. Five different batches of wheat were selected from NSW, VIC, QLD, WA and SA. Samples were exposed to a 2-step in vitro digestion assay that simulated gastric (pH 3.5 with 0.1M HCl and pepsin) and small intestine (pH 6 with 1M NaOH and pancreatin) phases of digestion in broiler chickens. Either 0 or 16,000 BXU/g xylanase (Econase XT 25, AB Vista Feed Ingredients, UK) was added. The samples were centrifuged and resulting supernatant prepared for analysis of XOS composition, along with standards of xylobiose (X2), xylotriose (X3), xylotetraose (X4) and xylopentaose (X5) (Morgan et al., 2018). The standards and samples were analysed on a Shimadzu LCMS-8050 with a C18 HPLC column by electrospray ionization.
