Arabinoxylans are the predominant fiber component in cereal grains and cereal co-products. They have a backbone of β-(1− 4) linked xylose units with side chains of arabinose, glucuronic acid, acetyl, and phenolic acids. Xylanase hydrolyzes the β-(1− 4) glycosidic bonds between xylose units in the backbone and releases a mixture of xylose and xylo-oligosaccharides that can be either absorbed or fermented by pigs. Previous data indicate that xylanase increased the degradation of dietary fiber and increased energy digestibility in diets for growing pigs and lactating sows. Xylo-oligosaccharides improve growth performance of nursery pigs because they serve as prebiotics that modulate gut microbiota. A stimbiotic (i.e., xylanase in combination with xylo-oligosaccharides) may improve growth performance of weanling pigs to a greater extent than either additive alone by shifting the intestinal microbiome to favor fiber fermentation. However, there are no data on possible effects of xylanase in sows diets on growth performance and intestinal health of the offspring or on the impact of the stimbiotic on digestibility of nutrients when fed to nursery pigs. Therefore, an experiment was conducted to test the hypothesis that xylanase or a stimbiotic improves growth performance and the apparent total tract digestibility (ATTD) of dry matter (DM), gross energy (GE), and total dietary fiber (TDF), and the concentration of digestible energy (DE) of diets for weanling pigs, but that the effect is greater in offspring of sows fed xylanase in lactation than in offspring of sows not fed xylanase.
