Detailed Product Description

Physical and chemical properties
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.

Mechanism of action
Endogenous amylase can only break down α-1, 4-glycosidic linkages, but β-1, 4-glycosidic linkages in XOS are scarcely decomposed by animal digestive enzymes. XOS 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, XOS may bind to plant agglutininglycoproteinon 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. XOS 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.
Main physiological effects
1. Stimulate the growth of beneficial microorganisms, inhibit the growth of harmful microorganisms, and improve the balance of microflora in intestine.
2. Prevent the bind of pathogenic bacteria to host cell acceptor.
3. Stimulate the immune system and enhance the immunocompetence of animal.
4. Improve the tolerance of disease, reduce the incidence of diseases and improve the control efficiency.
5. Improve the feed efficiency and increase the animal performance.
6. Reduce the environment contamination and improve animal sanitation.
Characteristics:
High stability
XOS is very stable and can resist all digestive juice of animals; they are stable under acid condition of animal stomach. With high thermal stability, XOS can not be decomposed at 120-150, thus resisting all extreme condition of feed process.

The residual ratios of XOS in vitro digest experiment (%, w/w)

Digestive juice	Residual rate
Saliva	100.0
Gastric juice	99.9
Pancreatic juice	99.8
Enzyme of small intestine mucosa	99.6

No forbidden compatibility
XOS has little effect on other components of feed and is not affected by components of feed.
High activity with low addition
The dosage of XOS 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.
Application
Kangweisu is applicable for supplementing to the livestock, poultry and aquiculture.
