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
The invention belongs to animal husbandry animal nutrition and feed technical research field, relate to a kind of feed formula that zytase and 'beta '-mannase be feed addictive of take, say more specifically a kind of application that regulates weanling pig intestinal contents microbiota and reduce the aspects such as small intestine contents viscosity.
Background technology
The daily ration of raising livestock and poultry be take corn-soybean meal as main, along with corn industry consumption constantly increases, causes fodder maize increasingly in short supply, and therefore, developing other feed resources becomes one of effective way solving energy feed shortage.Wheat is as the main cereal crops of China, and output is high, nutritive value is abundant, good palatability, and the application in animal and fowl fodder is increasingly extensive.
China's wheat resource is abundanter, and annual production is 200,000,000 tons of left and right, is only second to paddy rice, corn occupies the 3rd.Compare with corn, wheat nutritive value is higher, and wherein crude protein content is 13% ~ 16%, and lysine content is 0.31%-0.37%; Content of mineral substances is abundant, and copper, manganese, zinc content are higher, and calcium, phosphorus content are approximately 3 times of corn, and in wheat, contain natural phytase, can improve the utilization rate of phosphorus.Wheat is not except containing carrotene, and vitamin E and B family vitamin content are all substantially suitable, visible higher than metabolizable energy and the corn of corn and wheat, and wheat nutritive value is abundant, as alternative Partial Protein feed in energy feed, reduces feeding cost.Yet, in wheat, contain more SNSP (NSP), mainly comprise xylan, mannosan and araban etc., account for the more than 6% of wheat dry weight, can not be digested by animal digestive ferment, there is anti-oxidant action.In addition, mannosan is present in the middle of multiple beans, and in its process, for example, in dregs of beans production process, effectively place to go mannosan, enters the follow-up supervention of animal and bird intestines and wave its anti-oxidant action, affects animal intestinal healthy.
The anti-oxidant action of SNSP is mainly manifested in two aspects: increase intestines and stomach chyme viscosity, SNSP increases enteron aisle chyme viscosity, cause the motionless water layer thickening on small intestine surface, affect contacting of chyme and small intestine surface, reduced the absorption rate of nutrient; Destroy intestinal microbial balance.NSP reduces nutrient digestibility, the nutrient content that enters enteron aisle back segment is increased, for bacterial growth breeding provides good environment, simultaneously, chyme is by gastral Speed Reduction, bacterium and harmful microorganism can not be got rid of external in time, strengthen the destruction to intestinal environment, cause breeding performonce fo animals to decline.
Therefore, consider that in wheat, NSP main component is xylan, contain more mannosan in dregs of beans, therefore, we add special complex enzyme formulation for this daily ration, to reduce the anti-oxidant action of NSP, improve nutrient digestibility, finally promote growth of animals or poultry.
Summary of the invention
