Abstract
this paper relates to a feed additive for broiler chickens. The feed additive comprises the following components by weight: 90%-95% of traditional Chinese medicine compounds and 5%-10% of bacteriocin. The feed additive of the invention can improve feed conversion rate, promote broiler chicken growth, regulate immune function, and enhance disease resistance.
Description
Technical field
The invention belongs to feed industry and livestock breeding industry field, be specifically related to a kind of feed additive for chickens that utilizes bacteriocin, Chinese medical extract preparation.
Background technology
In modern farming is produced, antibiotic has played indelible effect aspect disease preventing and treating, but use for a long time the caused antibody-resistant bacterium problem of antibiotic, the problems such as autogenous infection are having a strong impact on the sustainable development of animal husbandry, and use for a long time antibiotic also can suppress and kill the profitable strain in animal body, cause archenteric flora disorder, cause digest and assimilate bad, affect absorption and the utilization of feed, simultaneously, the teratogenesis that impact on human health of antibody-resistant bacterium potential and medicament residue bring, carcinogenic, the problems such as mutagenesis more and more receive social concern.The research of Substitutes For Antibiotic is just in the ascendant.
Bacteriocin is polypeptide or the Precursor Peptide that a class that some bacterium produces by Ribosome biogenesis mechanism in metabolic process has bacteriostatic activity, scope of restraining fungi do not limit to in the bacterium of homology, produce bacterium bacterium have to LADA.The more bacteriocin of research is lactein at present.Research shows; lactein has protective effect to fowl poultry intestines and stomach; it has inhibitory action well to the pathogen of the animal intestinals such as Escherichia coli, staphylococcus aureus, shigella flexneri, Pseudomonas aeruginosa, monospore hyperplasia Li Site bacterium; simultaneously; lactein can promote the secretion of gastric juice; the digestion that strengthens stomach and intestine is wriggled, and food is digested and assimilated better.In addition, lactein can promote the growth and breeding of lactic acid bacteria, reduces the pH value of enteron aisle, thereby suppresses and killing microorganism, regulates the balance of the intestinal microflora of animal.Lactein not only has the similar beneficial effect of antibiotic feed additive, and nontoxic, have no side effect, noresidue, without the resistance to the action of a drug, and there is good diffusivity, also free from environmental pollution.Just because of these character, allow lactein replace antibiotic become gradually possibility, make livestock birds health and livestock products safety and breeding ecological obtain safely further assurance.
Chinese herbal medicine is the product of the distinctive theory of traditional Chinese medical science of China and practice, is the material that a class has nutrition and medicinal double action concurrently.The research of recent domestic and test confirm, use Chinese herbal feed additive in poultry production, have the physiological function that regulates poultry body, strengthen premunition, improve the effect of the aspects such as production performance.Chinese herbal feed additive, with the feature of its natural sex, security reliability, low toxic and side effect and environmental protection, more and more receives people's concern.
At present Chinese herb feed additive has been applied to broiler fodder and has added, but the interpolation in broiler fodder does not also appear in the newspapers about bacteriocin, and the two is combined with especially and does not have.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide one can improve feed efficiency, promote growth of meat chicken, regulate immunologic function, strengthen resistance against diseases, substitute antibiotics, Chinese herbal medicine and the compound broiler chicken high-efficiency feed additive of bacteriocin of reduction feed cost and aquaculture cost.
The present invention can be achieved through the following technical solutions:
A kind of feed additive for chickens, by quality percentage composition, comprises Chinese herbal compounds 90%-95%, bacteriocin 5%-10%.
Above-mentioned feed additive for chickens, described Chinese herbal compounds is counted as Chinese bulbul 18%-22%, Radix Astragali 18%-22%, coptis 4%-6%, Radix Codonopsis 13%-17%, rheum officinale 13%-17%, honey-fried licorice root 8%-12%, hawthorn 14%-16% by quality percentage composition.
Above-mentioned feed additive for chickens, the bacteriocin of telling is lactein, concentration is 1.5 × 10
6iU/g.
The preparation method of Chinese herbal compounds is: by above-mentioned each taste medicine through 105 ℃ of oven dry, pulverizing, cross 80 mesh sieves after by above-mentioned 7 tastes according to described ratio matching component, just obtain Chinese herbal compounds.
The preparation of feed additive for chickens of the present invention comprises the following steps: (1) takes various raw materials according to the weight prescription predetermined ratio of the composite feed additive that promotes growth of meat chicken and raising immunity; (2) add Chinese herbal compounds, mix; (5) add again lactein to mix.Beneficial effect of the present invention:
1. promote growth of meat chicken, increase and improve broiler chicken immunocompetence, improve anti-oxidation function, can improve broiler chicken survival rate.Improve the production performance of broiler chicken etc.;
This promotion growth of meat chicken and improve immunity composite feed additive noresidue, have no side effect, it lays particular emphasis on the complete unification that promotes animal body and interior environment, keeps ecological balance, and reaches the object of anosis health care.
