Introduction of xylooligosaccharides
Xylooligosaccharide (XOS), also known as xylooligosaccharide, is a functional polymeric sugar formed by the combination of two - seven xylose molecules through a β-1,4-glycosidic bond. Xylo-oligosaccharides can be extracted from hemicellulose-rich materials such as corn cobs, bagasse, straw, and straw. Commercialized xylooligosaccharides are mainly obtained from materials such as corn cobs by bio-enzymatic methods.
Mechanism of action of xylooligosaccharides
Xylooligosaccharides mainly regulate the micro-ecological balance of the organism (double barrier theory).
Biological barrier: xylooligosaccharide selectively proliferates the body Bifidobacterium, Lactobacillus and other beneficial bacteria, promotes the colonization and proliferation of beneficial bacteria; forms a dominant flora, inhibits the adhesion of harmful bacteria in the intestine.
Chemical barrier: During the process of proliferating beneficial bacteria, short-chain fatty acids are produced. As the concentration of short-chain fatty acids increases, the pH of the colon of the animal is reduced, which is a suitable condition for destroying the proliferation of harmful bacteria.
Application of feed grade xylooligosaccharides in animals
Application of xylooligosaccharides in pigs. The xylooligosaccharide is used in the production of weaned piglets, fattening pigs and sows, which can improve the production performance, improve the intestinal flora and intestinal structure, and improve the body immunity; it has the effect of reducing the diarrhea rate for weaned piglets; For pregnant sows, the problem of constipation can be improved.
The application of xylooligosaccharides in chickens. The application of xylooligosaccharide in chicken production can improve the production performance, improve the intestinal flora and intestinal structure, and improve the immunity of the body; it can also improve the egg production rate and reduce the damage rate and the second time in laying hens. Egg rate, improve the regular quality of eggs, lower cholesterol.
Application of xylooligosaccharides in aquatic animals. The use of xylooligosaccharides in the production of aquatic animals can improve the production performance, improve the intestinal flora and intestinal structure, and improve the body's immunity.
Addition of xylooligosaccharide in animal husbandry
1. It is applied to livestock health products, and it is generally added in the form of compounded with xylooligosaccharides and Chinese herbal medicines, vitamins, trace elements and probiotics.
2. Applied to additive premixes. The xylooligosaccharide and various additives, including enzyme preparations, multi-dimensional, live bacteria, etc., form a new type of additive product, which is supplied to the feed manufacturer or farm for addition.
3. Directly added to core materials, premixes, high-end commercial materials, etc.
4. For aquaculture integrated enterprises, they can be directly added to the feed for feeding, grabbed from the source, take a healthy breeding route, reduce the use of drugs, and create economic benefits and environmental ecological benefits of the entire industrial chain.
5. In combination with therapeutic drugs, restore intestinal health in time, avoid bacterial infection, increase feeding in advance, and quickly restore health.
