With the development of society and economy, people's demand for pollution-free livestock and poultry products has become increasingly urgent. The UN Food and Agriculture Organization of the United Nations (FAO), the International Organization for Animal Health (OIE), and the World Health Organization (WHO) jointly proposed the concept of "resistance beginning" to control the use of veterinary medicines in order to prevent tremendous harm to humans. Therefore, the new non-polluting, non-residual and pollution-free safe green feeds and feed additives have become the hotspots and focuses of current research and development. Among them, xylo-oligosaccharides are used in many products due to their unique health promoting effects and safety on animals. Outstanding, attracted much attention. Use value Xylo-oligosaccharides, as bioactive substances, have become more and more widely used as feed additives in the feed industry. Xylo-oligosaccharides can improve animal performance and feed conversion rate, prevent diarrhea and constipation of livestock and poultry, enhance animal immunity and disease resistance, reduce drug dosage in feed, reduce drug residues and improve animal product quality, and improve the intestinal integrity of livestock and poultry. Microecological balance and other advantages. Effect on Intestinal Population of Broilers Changing the morphology of intestinal tissue by intestinal microbes has a great influence on metabolism and function, and establishes a good intestinal microflora, which helps to improve animal performance and feed conversion rate. Tests have shown that xylo-oligosaccharide can significantly reduce the number of E. coli and increase the number of lactic acid bacteria compared with the experimental control group. Effect on Broiler Growth Performance Xylo-oligosaccharides have the functions of promoting the proliferation of beneficial bacteria such as bifidobacteria in animals, inhibiting harmful bacteria, and reducing intestinal putrefaction substances, thereby improving animal immunity and promoting growth and development. The test showed that: adding xylo-oligosaccharides can increase the body weight of Huainan chickens from 21 days to 42 days (P>0.05), and significantly reduce the feed-to-weight ratio (P). Effects on Chicken Serum Immunology Tests showed that xylo-oligosaccharides increased serum levels of immunoglobulin (p>0.05); serum levels of IgG, IgA, and IgM increased, and IgA and IgM reached significantly different levels (P summary Xylo-oligosaccharides are one of the better products of the oligosaccharides that have good function of proliferating bifidobacteria, inhibit the growth of pathogenic bacteria spoilage bacteria and purify the intestinal tract; they can stimulate the immune system of the chicken body, enhance immunity and disease resistance of the body. Force, thereby reducing the incidence rate; improving the growth performance of broilers; increasing the absorption and utilization of nutrients, reducing the amount of residual protein in the excreta, reducing the amount of ammonia produced in the house, and improving the environmental sanitation of the house. The health of chickens and breeders are all favorable; the feathers of chickens are of bright color and good color; they can play a better role in reproduction; they have good social and economic benefits. Therefore, xylo-oligosaccharides, as a new type of safe green feed additive, has positive significance for the promotion of animal husbandry product upgrading and industrial development in China, and its market prospects will be very broad. 5 Inch Face Access Control,5-Inch Face Recognition Attendance Access Control,Face Recognition Attendance Access Control,Office Face Recognition Access Control System Shenzhen BIO Technology Co.,Ltd. , https://www.huifantech.com
