Problems solved by technology

[0004] The anti-nutritional effect of non-starch polysaccharides is mainly manifested in two aspects: increasing the viscosity of gastrointestinal chyme, and non-starch polysaccharides increase the viscosity of intestinal chyme, resulting in thickening of the immobile water layer on the surface of the small intestine, affecting the relationship between chyme and the surface of the small intestine. Exposure to reduced nutrient absorption and utilization; disruption of intestinal microbial balanc

Abstract

The invention discloses a composite enzyme compound feed capable of improving the intestinal health of weaned pigs. The composite enzyme compound feed comprises the components by weight parts: 70-75 parts of wheat, 5-8 parts of wheat bran, 13-18 parts of bean pulp, 1-5 parts of fish meal, 0.2-1 part of glucose, 0.1-1 part of calcium hydrogen phosphate, 0.5-1 part of limestone powder, 0.1-0.5 part of table salt, 0.5-1 part of L-lysine hydrochloride, and 1-4 parts of a piglet premix material, and also comprises the components of: 5,000,000 U/ton of xylanase and 400,000U/ton of beta-mannase. After weaned pigs are fed by using the composite enzyme compound feed for four weeks, the influence of the feed formula to the micro-chyme viscidity of small intestine contents and the quantity of escherichia coli can be discussed, and the influence to the growth performance of the weaned pigs can be tested. The results prove that in an experimental group, the viscidity of the small intestine contents of the piglets is very remarkably reduced, and the quantity of escherichia coli of jejunum and ileum contents is remarkably reduced; and the growth performance comparison proves that the average daily gain of the piglets can be remarkably increased. Therefore, after the xylanase and the beta-mannase with the appropriate proportions are added into a wheat-bean pulp-fish meal type feed for the weaned pigs, the growth performance of the weaned pigs can be improved by improving the intestinal health of the weaned pigs.

Description

technical field [0001] The invention belongs to the research field of animal nutrition and feed technology in animal husbandry, and relates to a feed formula using xylanase and β-mannanase as feed additives, more specifically, a method for regulating the microbiome of intestinal content of weaned piglets system and reduce the viscosity of small intestinal contents. Background technique [0002] The rations for raising livestock and poultry are mainly corn-soybean meal. With the continuous increase of the industrial use of corn, the shortage of corn for feed is becoming more and more serious. Therefore, the development of other feed resources has become one of the effective ways to solve the shortage of energy feed. As the main food crop in my country, wheat has high yield, rich nutritional value and good palatability, and it has been widely used in livestock and poultry feed. [0003] my country is relatively rich in wheat resources, with an annual output of about 200 milli...
