Application of Xylo-oligosaccharide in feeding

Prebiotics—Xylo-oligosaccharides is a new type of feed additive that is newly developed in recent years and is non-polluting, non-residual and unique in function. Xylo-oligosaccharides have the following unique advantages in the feed industry:
First, highly selective, to promote the proliferation of bifidobacteria: xylo-oligosaccharides is the most potent one of the functional oligosaccharides in proliferating bifidobacteria, its efficacy is nearly 20 times that of other oligosaccharides. Because there is no enzyme that decomposes xylo-oligosaccharides in the animal body, xylo-oligosaccharides can reach the colon directly and are used by beneficial bacteria in the intestine to regulate and maintain the balance of the intestinal flora. The metabolites also inhibit the breeding of harmful bacteria. Improve immunity. Bifidobacterium and Lactobacillus and other beneficial bacteria can use xylo-oligosaccharides to synthesize various vitamins, proteins and unknown antibody factors in animals and promote the absorption of calcium, zinc, iron and vitamin D, and other nutrients. Growth and improve feed conversion, protein utilization and meat quality, reduce feed coefficient, improve production performance.
Bifidobacteria and lactobacillus metabolized vitamins, unknown antibodies, etc. can help the liver break down drug residual toxicity. Xylo-oligosaccharides also stimulate the immune system of grass carp and increase the activity of glutathione peroxidase and superoxide dismutase.
Second, the intake is small, cost-effective, good compatibility: Xylo-oligosaccharide is currently found that the least effective amount of oligosaccharides, the most cost-effective, low-poly xylose has a good compatibility, it is a variety of feed The ingredients have no effect and are not affected by the ingredients in the feed.
Third, acid, thermal stability: in the pH range of 2.5 to 8.0 is quite stable, in this range 100 °C heating 1 liter, xylopolymer hardly decompose, therefore, do not worry about xylo-oligosaccharide processing or Decomposition of active ingredients that may result from storage.
Grass carp is a unique species of fish in China. It grows fast, has large individuals, is simple in diet, and has a wide source of feed. The largest individual can reach 35 kilograms. Because of its tender meat, delicious taste, and high yield, and herring, mackerel, and squid are known as the world famous "Four Home Fish", they are often used as the main breeding ground for pond culture and lakes, reservoirs, and river courses. It has also become the primary choice in aquaculture.
In culture, common diseases of grass carp are red skin disease, gill disease, and enteritis disease. In aquaculture, antibiotics and antimicrobial agents are often used to prevent and treat these diseases to reduce their impact on grass carp growth. However, due to the existence of drug residues and drug resistance problems, it poses a hazard to human health, making the development of alternatives to antibiotics and antibacterial drugs a hot topic in recent years. Therefore, Xylo-oligosaccharides feed additives are safe, efficient, non-polluting and non-residual new additives. They are the best ones among the prebiotic additives and are also recognized by the industry as superb bifidogenic factors.
With the rapid development of the aquaculture industry and the increasingly fierce competition in the feed industry, the harm caused by antibiotics has become more and more severe. People are increasingly vocal about the safety of animal foods, and the feed-grade low-polymerized xylose has no pollution and no toxic side effects. , No residue, can not only improve the ability of disease prevention and disease resistance, reduce the feed coefficient, but also can greatly improve the performance of grass carp, fully in line with the development of green, safe and environmentally friendly feed. The widespread application of forage xylose in aquaculture is bound to be an inevitable trend in China's aquaculture industry and feed industry.
