Description
Technical field
The present invention relates to additive agent field, specifically, relate to a kind of animal feed additive.
Background technology
Grease is the main energy supply material in bird feed, and modern commerceization cultivation adds the grease of higher proportion conventionally in order to improve breeding performonce fo animals in feed formula.Yet fat, due to its not hydrophilic feature, makes animal have certain particularity to digesting and assimilating of its.Fat to digest and assimilate be mainly to carry out in small intestine, because fat is water insoluble, and enzymatic reaction in body is carried out in the aqueous solution, so fat must just can digest in first emulsification.
The emulsifying agent existing in animal body is the cholate from gall-bladder, first it purify fat, reduce its surface tension, then make Fat Emulsion change into very tiny emulsification particulate and then thoroughly be decomposed by the pancreatic lipase in small intestine, form with chylomicron is absorbed by intestinal microvillus again, by blood, is transported to each tissue of health.Poultry is because autodigestion road is shorter, make the hyposecretion of enteron aisle digestive system endogenous emulsifying agent-bile acid, how Feed Enterprise adds animal fat or animals and plants compound lards in fowl material in order to reduce production costs now in addition, the saturated fatty acid that contains higher ratio in this grease, has aggravated the burden that poultry absorbs oil and fat assimilation.
At present, the feeding emulsifying agent in nundinal is divided into two large classes, and a kind of is bile salt type, and another kind is phosphatide type.Wherein bile salt is the naturally occurring emulsifying agent of animal's liver secretion, after exogenous interpolation, enter animal alimentary canal and whether can cause the secretion of animal's liver feedback inhibition bile, academia does not form unified suggestion always, and bile salt emulsifying effectiveness and emulsion stability that external source is added are poor; Commercially available phosphatide type emulsifying agent, adopts common phosphatide and some other surfactant compound, and emulsifying capacity and emulsion stability are not strong, and action effect is poor.In addition, emulsifying agent arrives small intestine and just starts to exercise its important effect after being taken in by animal, it in animal body, is a complex environment, especially lower pH value in stomach, can affect the effect of a lot of emulsifying agents, cause emulsifying capacity to reduce, therefore overcoming hydrochloric acid in gastric juice seems particularly important to the impact of emulsifying agent.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned defect, provides a kind of and can tolerate lower pH value and improve the animal feed additive of animal to the rate that digests and absorbs of grease.

As a kind of improvement:
Described lecithin is phospholipase A
1the modified lecithin of a fatty acyl group is removed in hydrolysis.
Lecithin has emulsification, can make neutral fat and cholesterol be decomposed into the scintilla harmless to animal body, make it to enter metabolic process, and be dissolved in the water and excrete, by emulsification, can reduce cholesterol, blood fat in blood, make blood circulation unblocked.Lecithin also has good hydrophily and lipophile, and choline and the acetyl of lecithin is combined into " acetylcholine " and can be brain sufficient nerve conduction material is provided, thereby regulates blood fat, alleviate fatty liver.Through the phosphatide of phosphatidase modification, compare with common lecithin in chemical constitution and increased hydrophilic hydroxyl, therefore there is higher HLB value, the applicable O/W type emulsifying agent of doing.
Rhamnolipid is the biosurfactant by a kind of biological metabolism character of pseudomonad or the generation of Burkholderia class, belong to anion biosurfactant, there is oil, water is amphipathic, can reduce water surface tension, can be used as wetting agent, emulsifying agent and blowing agent uses, rhamnolipid biological surface activator can be used in temperature, pH value and salinity under extreme situation, and nontoxic, can biodegradation.
Phosphatide after rhamnolipid and modification utilizes liposoluble dressing to make microparticle, reduce the impact of animal stomach inner acidic on it, when it enters after small intestine with feed, in body, pH value is greater than 5.5, enteric coating dissolves rapidly, phosphatide after rhamnolipid and modification is discharged in small intestine, with oil mixing with water, effective and stable chyle fat.
Polyglycereol fat ester has hydrophilic, oleophylic double grading concurrently, has the multiple performances such as well emulsify, dispersion, moistening, stable, foaming.In metabolic process, can decompose in vivo, thereby participate in metabolism, there is tight security, while polyglycerol ester quite stable in acidity, alkalescence and neutral environment, chance salt content also has fine emulsibility when higher.
Mono succinate glyceride is the esterification products of glycerine, aliphatic acid and butanedioic acid, is parents' molecular structure, belongs to nonionic food emulsifying agent.Its emulsifiability is between oil-in-water (O/W) and Water-In-Oil (W/O).There is safe, acidproof, salt tolerant, the water-disintegrable feature such as good.
Water soluble starch is a kind of between starch and starch sugar, and through controlling the low degree hydrolysis prods forming, this product aquation power is stronger, be solubilized at normal temperatures, the viscosity that has good humidity, has good carrier function, almost there is no sugariness or sweetless, heat resistance is strong, be difficult for brown stain, have good emulsification and thickening effect, hygroscopicity is little, be difficult for conglomeration, the advantages such as good film-forming property.
Owing to having adopted technique scheme, animal feed additive of the present invention has good tolerance to physiological environment complicated in animal body, and emulsifying capacity is strong, and stability is high, overcome the destruction that feeding emulsifying agent is in the past subject to hydrochloric acid in gastric juice, ion concentration, affected a difficult problem for emulsifying capacity performance.Be conducive to improve the especially emulsification of animal fat in animal alimentary canal of fat, increase the contact area of lipochondrion and lipase, strengthen pipe intestinal digesting function and liver metabolism function, promote fatty emulsification and absorption, improve body Nutrition and Metabolism, obviously improve breeding performonce fo animals; Improve the digest and absorb rate of animal to grease, can reduce grease amount, reduce costs; Promote the absorption of liposoluble vitamin; The disease of digestive tracts such as the diarrhoea that minimizing causes because of fat indigestion, enteritis.
Below in conjunction with the specific embodiment, the present invention will be further described.
