Abstract

The invention relates to a composite feed additive, in particular to an immunity enhancer which is applicable to breeding livestock, poultry and aquatic animals. The composite feed additive comprises the following components by weight percent: 25% or more of beta-glucan, 20% or more of mannan, 3.00%-4.50% of alanine, 1.20%-1.80% of arginine, 2.90%-3.50% of aspartic acid, 4.00%-5.50% of glutamic acid, 1.65%-2.25% of glycine, 0.70%-1.25% of histidine, 1.90%-2.45% of isoleucine, 2.80%-3.35% of leucine, 2.15%-2.85% of lysine, 0.65%-1.05% of methionine, 2.15%-2.75% of phenylalanine, 1.85%-2.35% of proline, 0.35%-0.85% of tryptophan, 2.20%-2.75% of threonine, 0.80%-1.20% of tyrosine, 2.40%-2.90% of valine and 2.00%-4.5% of crude fiber. The adoption of the composite components can realize good immune effect and stable effect, enhance the immunity of animal organisms and avoid the negative feedback inhibition phenomenon caused by long-term use for breeding.

Description

A kind of composite feed additive

Technical field

The present invention relates to feed addictive, the immunopotentiator of especially a kind of suitable raising livestock and poultry and aquatic livestock.

Background technology

Aquaculture is the basis of national economy.The breeding technology of good livestock and poultry and aquatic livestock kind, science is the key that promotes aquaculture development.In the existing breeding technology, when raising, livestock and poultry and aquatic livestock often need use antibiotic.Since over half a century, great impetus has been played in the antibiotic develop rapidly that is applied as livestock and poultry and aquaculture of aquatic animal industry, brought rich profit, but its side effect is also obvious day by day.A large amount of antibiotic that use cause that autogenous infection or suprainfection are more and more serious, make the animal immune function reduction, and even more serious is that it can threaten to human beings'health through food chain.Therefore, restriction uses antibiotic cry increasingly high in the world.There are problems such as medicament residue and bacterial drug resistance to antibiotic feed additive; Enhancing from people's environmental consciousness and health perception; The immunopotentiator of a kind of new feed addictive---single component comes out; It raises the existing many reports of application facet both at home and abroad livestock and poultry and aquatic livestock, but existing single component immunopotentiator not only action effect is limited, effect is understable, and on culturing the long-term appearance of negative feedback inhibition problem that tends to of using.People urgently hope that a kind of green is arranged, the appearance of environmental protection, safe, effective immunopotentiator as feed addictive.

Summary of the invention

The present invention is intended to overcome that the immunopotentiator immune effect of prior art single component is limited, effect is understable, and on culturing the long-term deficiency that tends to the appearance of negative feedback inhibition of using, release a kind of compound additive agent for feeding.It is a kind of composite immune reinforcing agent; Its good immune effect, effect stability, and the phenomenon that long-term use can the appearance of negative feedback inhibition on culturing make an addition in the feed; Improve livestock and poultry and organism immunity of aquatic livestock, can reduce even stop antibiotic use in the breeding process.

For this reason, a kind of composite feed additive of the present invention adopts following technical scheme:

The component and the weight percent content thereof of a kind of composite feed additive of the present invention are: beta glucan is equal to or greater than 25%, and mannosan is equal to or greater than 20%, alanine 3.00%-4.50%, arginine 1.20%-1.80%; Aspartic acid 2.90%-3.50%, glutamic acid 4.00%-5.50%, glycine 1.65%-2.25%; Histidine 0.70%-1.25%, isoleucine 1.90%-2.45%, leucine 2.80%-3.35%; Lysine 2.15%-2.85%, methionine 0.65%-1.05%, phenylalanine 2.15%-2.75%; Proline 1.85%-2.35%, tryptophan 0.35%-0.85%, threonine 2.20%-2.75%; Tyrosine 0.80%-1.20%, valine 2.40%-2.90%, crude fibre 2.00%-4.50%.

Each component of said weight percent content is pulverized respectively, crossed the 80-120 mesh sieve; Mix; Packing promptly is a product of the present invention.

In the process of pulverizing, mixing, temperature remains on 20 ℃-40 ℃, and controlled humidity stirs down at the state of sealing, and strict control time of stirring, and avoids the active ingredient heat loss, the contacting of also try one's best minimizing and moisture, air.

Compare with prior art; Beneficial effect of the present invention is: adopt composite parts, both contained daily needed each seed amino acid of animal, added the immunocompetence factors such as multiple antibody beta glucan that meets the animal health growth and mannosan again; Its good immune effect, effect stability; Can strengthen the immunity of animal body, and the phenomenon that long-term use can the appearance of negative feedback inhibition on culturing, digestion, the absorption of animal can effectively be promoted to nutriment; Promote growth of animal, improve the delivery and feed infant ability of animal.Specifically:

1, strengthens the non-specific immune function of animal body, improve livestock and poultry and aquatic livestock resistance and anti-stress ability, reduce disease and environmental stress adverse effect animal to general diseases.

2, can be used as efficient vaccine adjuvant and vaccine and unite use; Stimulate animal to produce specific immunity; Powerful more lasting immanoprotection action can be provided, improve immune protective rate, prevent and treat and multiple aquaculture is endangered huge stubborn disease (like pig mouth crow epidemic disease, bird flu and vibriosis penaeus).

3, have special antibacterial effect, can be absorbed in the enteron aisle inwall and suppress the field planting and the growth of pathogeny flora in the enteron aisle, promote the propagation of beneficial bacterium in the enteron aisle, thereby replace or reduce antibiotic dosage, the puzzlement of no drug residue.

4, have tangible growth promoting function, can be used as the natural short long agent of livestock and poultry and aquatic livestock.
