Nanchang 330045; 2 Jiangxi Science and Technology Normal University School of Pharmacy, Jiangxi Nanchang 330013; 3 Jiangxi Science and Technology Normal University School of Life Sciences, Jiangxi Nanchang 330013) 4iqabstract: As people continue to study feed, more and more enzymes are applied to various feed production industries, rather than starch polyglysase agents are one of themNon-starch polysaccharides (NSPs) are the main components of feed fiber, and most of the fiber shones nutrients in feed wrapped in cell walls, inhibiting the normal digestive function of animals, hindering the absorption of nutrients, resulting in the utilization of nutrients and reduced feeding efficiencyAdding enzymes to the feed can remove these NSPs, allowing the cell wall to release nutrients, thereby improving the utilization of metabolic energy and protein, and improving the production performance of all aspects of animalsTherefore, it is very important to study the effect of non-starch polysaccharide preparation seisy to improve the utilization rate of feed digestionThis paper gives an overview of the mechanism of non-starch polyglysase agents and the effect on weaned piglets4iqin the figure classification number: S816.71 document identification code: B article number: 1673-4645 (2014) 11-0059-03 With people's green, safe consumption concept of increasing, enzyme preparation in feed production has more and more attention, the application is increasingly widespreadAdding a certain amount of non-starch polysaccharide preparations to weaned pig food can effectively improve the digestion utilization rate of feed and improve the production performance of weaned piglets, thus bringing a certain economic and environmental benefits to farmers4iq1Overview of non-starch polysaccharides 4iqnon-starch polysaccharides (NSPs) refers to all carbohydrates in plant tissueexceptated starch, consisting mainly of cellulose, pectin, hemicellacell and resistant starch, the first three of which constitute the main cell wall components, while resistant starch is the product produced during production and processingDepending on solubility, non-starch polysaccharides can be divided into soluble non-starch polysaccharides (SNSP) and insoluble non-starch polysaccharides (INSP)Soluble non-starch polysaccharides mainly include arabic glycosaccharides, grape glycosaccharides, glycoglucose, beta-glucan and pectin, and are among the main factors affecting the production performance of livestock and poultry In addition, the high viscosity and water holding properties of non-starch polysaccharides make its anti-nutritional effect sharply, resulting in increased viscosity of the diet, decreased activity of physiological substances, changes in the intestinal microbiome, affecting the physiological form and function of the intestine, as well as the digestion and absorption of nutrients The mechanism of action of 4iq 2, non-starch polyglynese formulation 4iq 2.1 reduces the viscosity of intestinal diet 4iq the viscosity of nSP has a great relationship with its molecular weight, the higher the molecular weight, the higher its viscosity The main role of NSP enzyme preparation is to break down anti-nutrient factors, after adding enzymes in the diet, the large molecular weight of glucan components significantly reduced, small molecular weight of alaccosa and beta-glucan adhesion and water soluble significantly reduced, the viscosity of intestinal content decreased, so that the diet in the digestive tract easier transport and digestion and absorption, improve feed nutrient utilization rate, improve growth performance 4iq 2.2 Activate the secretion of endogenous enzymes 4iq piglets are stimulated by weaning stress early in their growth, and the endogenous enzyme secretion is insufficient Adding a certain percentage of NSP enzymes to NSP-rich feeds can increase the nutrient absorption by breaking down the corresponding starch or protein, increasing the nutrient component after decomposition, stimulating the secretion of endogenous digestive enzymes (e.g., increasing alpha-amylase activity Xu Weirong and others added NSP enzyme preparations to weaned pig barley diet, and the results showed that the activity of maltose, sucrose enzyme and lactase in the empty intestinal mucosa were improved respectively 4iq 2.3 Improve the lining of the gut 4iq The addition of NSP enzyme preparations, reduce the viscosity of the intestine, promote the digestion and absorption of nutrients, thus changing the environment in which the intestinal microorganisms grow and reproduce, reduce the number of pathogenic microorganisms, reduce the competitive absorption of nutrients, and reduce the side effects of NSP on the intestine, improve the intestinal structure, promote the rapid growth of intestinal fluff The results showed that the concentration of volatile fatty acids in the reflux and blind intestines increased and the intestinal morphology changed The effect of 4iq 3, non-starch polyglynease preparation on weaned piglets 4iq 3.1 to improve the intestinal environment, improve nutrient digestion rate 4iq weaned piglets are the most rapidly developed pigs, the highest feed utilization rate, the most conducive to targeted cultivation of the important stage Add non-starch polysaccharide preparations to weaned pig feed, can effectively degrade or eliminate anti-nutrition factors in feed, improve feed utilization rate, promote the growth of beneficial bacteria, inhibit the reproduction of harmful bacteria, improve the micro-ecological balance of piglets' intestines, significantly improve the average daily weight gain of weaned pigs, reduce the weight ratio, increase the amount of food harvest, improve nutrient digestion rate Yin et al added enzyme supips to weaned pig high NSP diet, and the results showed that the utilization rate of Arabic sugar, xylitose, semi-lactose and glycosaccharide in the intestines was significantly improved Xu Jianxiong and other studies show that the digestion rate of piglets increased by 9.67 percent and the digestion rate of crude protein increased by 15.4 percent when non-starch polysaccharides were added to the diet Zeng Fuhai and others have found that the addition of non-starch polysaccharide agents in daily grain can significantly improve the average daily weight gain and material weight ratio of piglets (P 0.05), and the average daily harvest is also increased (P 0.05) 4iq 3.2 improve blood sugar and protein levels 4iq glucose in the blood provides the main source of energy for weaned pigs, who intake glucose through intestinal absorption and liver sugar breakdown Non-starch polysaccharide preparation can improve the digestion rate of starch, starch decomposition in the form of glucose absorption into the blood, improve blood sugar concentration, promote its growth and development Adding enzyme synosis to feed can not only improve the blood sugar concentration of piglets, but also have an effect on promoting the synthesis of proteins in plasma and body Chen Qinghua and others added different levels of non-starch polyglycesome preparations to the daily grain of weaned piglets, and the results showed that blood sugar in piglets serum increased significantly and blood urea nitrogen content decreased Lu Qiufeng and others found that non-starch polysaccharides significantly increased the blood sugar and total protein content of weaned pigprecups (P 0.05); Wang Jinwei and others added NSP enzymes to wheat-type base feed, and the test results showed that the total protein and globulin content (P 0.05) in the weaning pig serum increased significantly 4iq 3.3 improve the growth performance of piglets 4iq non-starch polysaccharides can improve the mucosity of the porcupine gastrointestinal diet, high viscosity prevents the contact between nutrients and endoenzymes, hinders the movement of sugars, amino acids and other nutrients into the intestinal mucosa, resulting in a decrease in nutrient digestion and absorption Liu Qiang and other studies found that the strengthening of the viscosity of gastrointestinal esophageal diet, so that the absorption rate is reduced, the intestinal microbiome is unbalanced, and the endogenous enzyme activity is reduced Weaned piglets can not secrete non-starch polysaccharides that degrade NSP, therefore, adding non-starch polysaccharide to the diet can destroy the barrier effect of plant cell wall, promote the release of nutrients in intracellular so that they can be better digested by endogenous enzymes And the addition of exogenous digestive enzymes, can stimulate the secretion of endogenous digestive enzymes, significantly improve the growth performance of all aspects of weaning piglets Chen Qinghua and others will add non-starch polysaccharide feed piglets, the test results show that the apparent digestion rate of dry matter, crude fiber and energy has been improved, and 0.02% enzyme preparation addition level on piglet growth performance, nutrient digestion and absorption of the promotion effect is the most obvious Lu Qiufeng and other studies found that non-starch polysaccharide preparations can significantly reduce the rate of diarrhea in weaned pigs 4iq 4 Factors affecting the application effect of non-starch polysaccharide preparations 4iq 4.1 diet composition 4iq the content of non-starch polysaccharides contained in various feed crops is different, and cellulose on different fiber sources of the diet also have different effects, different fiber source of daily grain improvement degree is not the same In addition, the properties of enzymes from different sources vary, and the properties of enzymes from the same source sometimes vary Therefore, for different diet mix, the required non-starch polysaccharide preparation composition and content are also different 4iq 4.2 Animal species 4iq non-starch polysaccharide effect on piglets is not significant The need for non-starch polysaclyse preparations varies between different species of animals, different age stages of animals, and even the same animal during feeding with different feeds, so the amount of addition should be paid attention to when feeding 4iq 4.3 The functioning of 4iq enzymes in the digestive tract is affected by the animal's digestive tract environment, while lower pH in the stomach may have a significant effect on the activity of the enzyme Xylitose and beta-glucanase were very low in activity at pH of 2.5, slightly elevated at pH of 3.5, and the highest enzymes of various enzymes lived between pH 4.5 and 5.5 4iq 4.4 Processing and storage of 4iq in the production, processing, preservation, transportation and application of enzyme synopsis in all aspects of the activity of the enzyme, can lead to reduced efficacy, and, without special stability treatment of enzyme preparations are difficult to withstand the granulation process and maintain high vitality Therefore, various measures should be taken to effectively ensure the activity of non-starch polysaccharide preparations The practice of 4iq 5- summary 4iq has shown that adding non-starch polysaccharide preparations to the feed of weaned piglets can degrade soluble non-starch polysaccharides, reduce the viscosity of eating, reduce the proliferation of harmful microorganisms in the intestines of animals, improve the metabolic level of the body and enhance immunity With the further development of enzyme preparation research, the continuous improvement of application methods, the effect of continuous improvement, in the near future, the use of non-starch polysaccharide preparations will be more and more extensive 4iq
