UNASSIGNED: In broiler @entity1573 , feed additives, including prebiotics, are widely used to improve gut health and to stimulate performance. Xylo-oligosaccharides (XOS) are hydrolytic degradation products of arabinoxylans that can be fermented by the gut microbiota. In the current study it was aimed to analyze the prebiotic properties of XOS when added to the broiler diet. Administration of XOS to @entity1573 , on top of a @entity3505 /rye-based diet, significantly improved the feed conversion ratio. XOS significantly increased villus length in the ileum. It also significantly increased numbers of lactobacilli in the colon and @entity8466 in the caeca. Moreover, the number of gene copies encoding the key bacterial enzyme for @entity4876 production, @entity6854 : @entity598 CoA-transferase, was significantly increased in the caeca of @entity1573 administered XOS. In this group of @entity1573 , at species level, @entity10265 and Anaerostipes butyraticus were significantly increased in abundance in the colon and caecum, respectively. In vitro fermentation of XOS revealed cross-feeding between @entity10265 and A. butyraticus. @entity880 , produced by @entity10265 during XOS fermentation, was utilized by the @entity4876 -producing Anaerostipes species. These data show the beneficial effects of XOS on broiler performance when added to the feed, which potentially can be explained by stimulation of @entity4876 -producing bacteria through cross-feeding of lactate and subsequent effects of @entity4876 on gastrointestinal function.
