Xylo-oligosaccharide or XOS is originated from plant materials through modern biotechnology, is a non digestible oligosaccharide. This type of low molecular-weight carbohydrate can promote the growth of animals, improve feed conversion efficiency and reduce mortality without any side-effect. Therefore, XOS is regarded as "prebiotic". XOS is recognized as the best functional oligosaccharide due to its special characteristics such as high selectivity for proliferating Bifidobacterium spp. in intestine, high stability to animal´s digestive enzyme system, acidic stability, thermal stability and prominent compatibility with feed.
Xylo-oligosaccharide is a functional oligosaccharide that is composed of 2-8 xylose groups through β-1, 4-glycosidic linkages. The sweetness of XOS is 40% of sucrose. XOS is a yellowy or light brown power. The physical properties of some effective ingredients of XOS are shown in following table
Xylooligosaccharide is also hardly to be utilized by harmful microorganisms in intestine. Therefore, XOS can reach the end of small intestine and large intestine. XOS provides the nutrients for the beneficial microorganisms such as bifidobacteria, and selectively stimulate their growth. Furthermore, XOS can decrease the activity of enteric putrefactive and pathogenic intestinal bacteria. The beneficial microorganisms such as bifidobacteria may produce antimicrobial substances and decrease the secretion of endotoxin. As a bind receptor of pathogenic bacteria, Xylooligosaccharide may bind to plant agglutinin（glycoprotein）on pathogenic bacteria cell surface, thus reducing the chance to bind to the digestive tract epithelia. This indicates that the pathogenic bacteria could not proliferate for the lack of nutrition from the host and hunger to death or loss the pathogenic ability. As the barrier, XOS can prevent the attachment of pathogenic bacteria with host cell, decrease antibiotics tolerance of these dissociated pathogenic bacteria, and meanwhile enhance the effect of antibiotics on sterilizing and restraining bacteria. Furthermore, they can bind to toxin, virus and eukaryote surfaces. Xylo-oligosaccharide can stimulate immune system, promote interferon production, activate macrophage and T or B lymphocyte, enhance execution of natural killer cells, and promote antibody production and immune system. With the characteristics of dietary fiber, XOS can simultaneously improve the physiological structure of intestine; improve the absorption of feed nutrients and animal production.
The dosage of Xylooligosaccharide is one twentieth of malto-oligosaccharides and one seventh of fructo-oligosaccharides widely used in feed, due to its high biological efficiency. Good fluidity XOS will not become viscid in normal moisture and can be mixed evenly with other ingredients. The quality of XOS is very stable; therefore it can be stored for a long term, even in extreme conditions.
