The present invention relates to a compound oligosaccharide feed additive for improving daily weight gain of piglets, belongs to the technical field of animal feed, and is applicable to the livestock breeding industry. The compound oligosaccharide feed additive for improving the daily weight gain of piglets comprises chitosan oligosaccharide and mannan oligosaccharide compounded according to a weight ratio of 1:10-1:20. The weight purity of each component is as follows: the weight purity of chitosan oligosaccharide is not less than 85%, the weight purity of mannan oligosaccharide is no less than 95%, and the polymerization degree of chitosan oligosaccharide is 2-10. According to the present invention, the compound oligosaccharide feed additive can significantly reduce the amount of additive on the basis of ensuring the application effect, thereby saving the storage space and reducing the costs of additive.
Description
Technical field
The present invention relates to a kind of composite oligosaccharide feed addictive that improves piglet daily gain, belong to technical field of animal, be applied to livestock-raising industry.
Background technology
Oligosaccharides is a large class green feed additive of developing in recent years, is more and more widely used in feedstuff industry at present.Oligosaccharides is the general name of the low polymerization carbohydrate that is connected to form by glycosidic bond by 2～10 monose.Conventionally it is believed that oligosaccharides can not be digested and assimilated by humans and animals enteron aisle, but can promote the propagation of Bifidobacterium, is a class oligosaccharides that is conducive to intestinal health.The comparatively common oligosaccharides using as additive in feed at present has manna oligosacchride (MOS), FOS (FOS), wood oligose (XOS) and soy oligosaccharide etc.These oligosaccharides all can not be digested and assimilated by animal itself, just in enteron aisle, play adjusting microorganism species, promote intestinal health, indirectly promote the effect of growth of animal.Additive capacity is larger conventionally in actual use for these oligosaccharides, and owing to being indirectly-acting, so effect is not very clear and definite.But another oligosaccharides-chitosan oligosaccharide that Recent study is found but makes a big difference with these traditional oligosaccharides, and it can be can be used as signaling molecule and directly act on target organ by animal absorbed into serum after absorbed into serum, play direct somatotrophic effect.
Chitosan oligosaccharide is the product that shitosan further decomposes, and by 2～10 Glucosamines, by β-Isosorbide-5-Nitrae glycosidic bond, is formed by connecting, unique alkalescence, the positively charged animal fiber oligosaccharides of being that is that current occurring in nature is found.It is not decomposed in intestines and stomach, can be absorbed directly into blood by animal and act on target cell, continual and steady raising animal body immunity.Chitosan oligosaccharide can regulate peculiar information the function of target cell with chemical transfer mode, play a part courier, after information is transmitted, is excluded external, safe, nontoxic, noresidue.
Manna oligosacchride is the class novel antigens active material extracting from Yeast Cultivation cell membrane, is extensively present in konjaku flour, melon bean gum, sesbania gum and multiple-microorganism cell membrane.It is comprised of mannose and glucose, and because its bonding mode is special, animal self can not directly be degraded, but can be fermented by enteric microorganism, produce organic acid, methane, carbon dioxide and hydrogen etc., lower the pH value of intestinal environment, thereby suppress the growth of harmful bacteria.It can also strengthen the function of intestine immunity, improves the production performance of animal.
Summary of the invention
It is upper that the production performance of cultivated animals is mainly reflected in weightening finish, and for piglet, it is the most direct that daily gain embodies production performance especially, is also a most frequently used index.The composite oligosaccharide feed addictive that the object of this invention is to provide a kind of raising piglet daily gain of efficient, low dosage.Compound function oligosaccharide feed additive used in the present invention, by chitosan oligosaccharide and manna oligosacchride rational proportion, makes the effect of two kinds of oligosaccharides mutually collaborative, by two kinds of different approach, reaches growth promotion, improves the effect of daily gain.Meanwhile, by such proportioning, can greatly reduce the additive capacity in feed, for saving formula space, reduce interpolation cost significant.
The present invention is achieved through the following technical solutions:
A composite oligosaccharide feed addictive that improves piglet daily gain, consists of chitosan oligosaccharide and manna oligosacchride, and its mass ratio is 1:10-1:20;
Described each constituent mass purity is respectively: described chitosan oligosaccharide >=85%, described manna oligosacchride >=95%;
The described chitosan oligosaccharide degree of polymerization is 2-10.
The mass ratio of described chitosan oligosaccharide and described manna oligosacchride is preferably 1:17.
The invention has the beneficial effects as follows:
1, the present invention adopts the chitosan oligosaccharide that can be absorbed by animal body and the manna oligosacchride compatibility only working at enteron aisle, by two kinds of approach, promote the immunity of piglet to grow, make the effect of chitosan oligosaccharide and manna oligosacchride collaborative mutually, strengthen action effect separately, can more effectively improve piglet daily gain.
2, use separately manna oligosacchride higher as the common additive capacity of feed addictive, and the compatibility of chitosan oligosaccharide provided by the invention and manna oligosacchride is when guaranteeing effect, can significantly reduce additive capacity, save the space of feed formula, also reduce interpolation cost.
3, feed addictive of the present invention has no side effect to piglet, noresidue after using, and environmentally safe, is a kind of green feed additive of new type of safe simultaneously.
The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with embodiment, the present invention is described in further detail.But example is not as a limitation of the invention.
Embodiment 1
Improve a composite oligosaccharide feed addictive for piglet daily gain, main component is chitosan oligosaccharide and manna oligosacchride.Described each constituent mass purity is respectively: chitosan oligosaccharide >=85%, manna oligosacchride >=95%; The described chitosan oligosaccharide degree of polymerization is 2-10.
Chitosan oligosaccharide and manna oligosacchride are coordinated and obtain testing required composite oligosaccharide feed addictive according to the mass ratio of 1:17.
This composite oligosaccharide feed addictive is added in daily ration according to 0.05% of daily ration weight, carry out child care piglets.
The child care piglet that selects rear approximately 5 ages in days of wean, is divided into 3 groups at random, every group of 2 repetitions, and each repeats 12.Control group: basal diet; Test 1 group: basal diet+yeast cell wall 500g/ ton; Test 2 groups: the composite oligosaccharide feed addictive of basal diet+the present embodiment.22 days experimental periods.Feeding and management: free choice feeding, freely drink water, keep column home clean dry.Result of the test is in Table 1.
Table 1 is respectively organized production performance data (unit: kg)
Main active in yeast cell wall is manna oligosacchride and beta glucan, is feed addictive conventional in current feed.Result of the test shows, compares with control group, and the average daily gain of 1 group of piglet of test, feedstuff-meat ratio are all less than improving, and this may be on the low side with the addition of yeast cell wall relevant.Conventionally the recommendation addition of yeast cell wall in complete diet pellet per ton is 2-4kg, and in this test, the addition of 500g/ ton is obviously on the low side, does not play somatotrophic effect.And the average daily gain of 2 groups of piglets of test all increases significantly compared with control group and 1 group of test, and feedstuff-meat ratio also all has significant decline compared with control group and 1 group of test.The composite oligosaccharide that the present embodiment is described has significantly promoted the growth performance of piglet.
