Sow constipation is a common digestive disorder syndrome, mainly manifested as dysentery, fecal frequency reduced, dry stool, like an abacus bead. Sows with mild constipation will cause loss of appetite, inadequate nutrition intake, postpartum no milk, litter and other phenomena; serious sows will cause physiological disorders, mental disorders, secondary infection of other diseases, and even sows will die, causing serious harm to the pig industry. Sow * * constipation occurs in all stages of sows, but is most common in antenatal ten days and postpartum. The main reasons are due to inadequate exercise, inadequate drinking water, long-term high-dose abuse of antibiotics, high temperature and humidity and cold seasons.
It is very difficult to treat constipation in sows clinically. Artificial salts, sodium sulfate, magnesium sulfate and other drugs are usually used to slow down diarrhea and cooperate with antibiotics, but the effect is very little. The use of laxatives should not be too large to avoid miscarriage, stillbirth; the use of antibiotics is mainly to prevent secondary bacterial infections, but often more severe constipation. Therefore, it is urgent to choose an appropriate way to control constipation in sows, which can not only soften feces, but also promote gastrointestinal peristalsis. It is more important to establish gastrointestinal microecological balance to prevent constipation in sows than to treat constipation in sows.
Xylo-oligosaccharides (XOS), also known as xylo-oligosaccharides, are functional oligosaccharides, which are mainly composed of 2 to 7 xylose molecules linked by beta-1,4-glycoside bonds. Xylooligosaccharide is one of the strongest Bifidobacterium proliferative strains in polysaccharides. Its efficacy is nearly 20 times that of other polysaccharides. Xylooligosaccharides are not digested by digestive enzymes. Xylooligosaccharides can pass through the stomach and small intestine smoothly, enter the hind intestine directly, and are used by beneficial bacteria in the intestine, and are hydrolyzed into acetic acid. Short Chain Fatty Acid (SCFAs), such as propionic acid and butyric acid. Short-chain fatty acids can reduce the pH value of the intestine, inhibit the growth of harmful bacteria, regulate the balance of intestinal flora, protect intestinal health, stimulate intestinal peristalsis, increase fecal humidity, and maintain a certain osmotic pressure, thereby preventing constipation.
Xylooligosaccharides exist in some plants in nature, such as bamboo shoots and bananas. Xylooligosaccharides are part of plants, but the amount is very small. Japan Suntory Company is the first company in the world to start the industrial production of xylo-oligosaccharides. China also initiated the research on the industrial production of xylo-oligosaccharides during the Ninth Five-Year Plan. Shandong Longli Biotechnology Co., Ltd. is the largest xylo-oligosaccharide production base in the world, is the "National Sugar Engineering Center" Longli Branch Center issued by the Ministry of Science and Technology, has undertaken major national "11th Five-Year Plan", "12th Five-Year Plan", "National Torch Plan" and other major projects, on xylo-oligosaccharide has more than 50 patents Among them, the project of "corn cob enzyme preparation of xylo-oligosaccharides" won the second prize of national technological invention in 2006, and the project of industrialization key technology and application of thermophilic fungi xylanase won the second prize of national scientific and technological progress in 2011.
Shandong Longli Biotechnology Co., Ltd. has developed the application of xylo-oligosaccharides in animal husbandry through independent innovation for many years. In 2006 Longli Bio-xylo-oligosaccharides obtained the certificate of new products of feed and feed additives issued by the Ministry of Agriculture of China. In 2009 Longli Bio-oligosaccharides and other related units drafted the national standard of feed additive xylo-oligosaccharides (GB/T 23747-2009).
Feed xylo-oligosaccharide, as a safe, efficient, pollution-free and residue-free new additive, is one of the best oligosaccharide additives. It has been recognized as a super bifid factor by the industry. With the rapid development of the feed industry and increasingly intensified competition, people are increasingly calling for animal food safety-feed safety. Feed xylo-oligosaccharides are pollution-free, non-toxic, side-effects and residue-free. They not only have the ability of disease prevention and resistance, improve feed utilization efficiency, but also greatly improve the production performance of livestock and poultry. They fully meet the requirements of green, safe and environmentally friendly feed. The wide application of feed xylo-oligosaccharides will certainly make the feed science and technology level and breeding industry in China. Create brilliance again.
