YIDUOZYME X series products are xylanase preparations developed by GUANGDONG VTR BIO-TECH CO., LTD. with international advanced gene engineer strain, producing through liquid deep fermentation and several kinds of aftertreatment techniques. These series products have high enzyme activity with completed preparation forms, which can satisfy different demands of xylanase using.Xylan is one of the foremost anti-nutritional factors in common use feedstuff raw materialsXylan exists mostly in the secondary cell wall of vegetable cell,situates between lignose and other polysaccharide, acts as a connector. The amount of xylan contained in different plant varies. As we know, Xylan content in wheat and its by-product is very high, e.g., the xylan content in wheat bran is as high as 20 - 21%, which is the foremost anti-nutrition factor that affects the wheat materials' application in feedstuff. In fact, in our country, even in the most popular feed raw material i.e., corn meal, soybean meal, xylan is also the most important anti-nutrition factor. For instance, xylan content in corn is between 3.7 - 4.4%, occupies around 40% of cell wall overall composition, is the upmost anti-nutrition factor in corn. And the xylan content in soybean also reaches 6%. Besides,in other processing by-products such as rice bran, unconventional material, the content of xylan is even higher. So, xylan is universally existing in all kinds of feed raw materials,is one of the foremost anti-nutritional factors in feedstuff.The Anti-nutritional Effects of XylanIncreases Chyme Viscosity in Intestinal Tract, and Impact Animal's Digestion & Absorption Function.Monogastric animals themselves are incapable of secreting enzymes which decompounded xylan. While animal makes a meal of feed containing high ratio of water-solubility xylan, dissolubility xylan in animal intestinal tract forms stickum,and increase viscosity of the contents in intestinal tract. The increased viscosity will reduce the passing speed of chyme through intestinal tract, then leads to a decrease of feed intake, disturbs the mixing between the digestive juice and the substrate,postpone the digestion of digestive enzyme to the substrate. At the same time, it also reduces the diffusion velocity of nutrient substance in chyme in intestinal tract, and disturbs the absorption of nourishment.The Problems Which Yiduozyme X series Xylanase Can Solve Degrades xylan,reduces intestinal tract chyme viscosity, destroys the structure of vegetable cell wall,eliminates its anti-nutritional function,ameliorates animal productive performance; Increases metabolizable energy of feedstuff,promotes absorption and utilization of nourishment, enhances profita-bility of feed manufacturers and farming enterprises Eliminates the restraining function of xylan to endogenesis enzyme, prevents the peptic from compensatory hypertrophy Produces plenty of functionality oligosaccharidexylo-disaccharide, xylo-trisaccharide and so on,which can improve animal intestinal tract microscopic ecosystem,and benefit animal health Reduces the quality difference of feed product caused by feedstuff raw material quality variation,stabilizes product quality,and decrease customers' complaints Widens the range of raw materials used in feed,increase unconventionality raw material percentage used in feed manufacturing, such as bran, wheat shorts, rice bran and so on, consequently reduces formula cost of feed Increases absorption and utilization of nutrient substance,reduces feces excreted to protect environment; at the same time decreases stimulation of noxious gas produced by decompounding organic substance to livestock and poultry,and decreases the occurrence of respiratory diseases.The Advantage of Yiduozyme X Ser Xylanase Products International advanced gene engineering strain is adopted in production, through liquid submerged fermentation,producing higher enzyme activity with better quality cost ratio As a kind of single endo-xylanase,not including β-xylosidase and other exo-xylanases,it is more suitable to be used in feed industryThe
