In the past, studies have shown that linear xylooligosaccharides (XOS), non-digestible oligosaccharides produced by enzymic and/or chemical degradation of lignocellulosic materials having xylan as major hemicellulose component, promote the growth of health promoting bacteria, in particular lactobacilli and bifidobacteria, and therefore act as prebioticum. However, little is known about the effects of substituted XOS, in particular arabino-xylo-oligosaccharides (AXOS), on the mode of fermentation by intestinal microbiota. To see whether AXOS indeed have prebiotic effects, the influence of structurally different AXOS, obtained after enzymic and/or chemical degradation of lignocellulosic materials having arabinoxylan as major hemicellulose component, on the cecal microbiota of broiler chicks was studied. In addition, the effect of AXOS on the growth performance of broiler chicks was evaluated.
