Abstract

The invention discloses a method for preparing a feed additive free of antibiotics. The method includes the following steps that firstly, an organic antibiotic additive is prepared, wherein fresh bamboo leaves or fresh fungi are selected, smashed and then arranged in a funnel, an ethanol solution with the mass percent of 75% is added into the funnel, a switch is arranged at the bottom of the funnel, after the bamboo leaves or the fungi are totally immersed by the ethanol solution, the bamboo leaves or the fungi are steeped for three days in this way, and then the switch is opened, and extracting liquid is collected; secondly, the extracting liquid obtained from the first step undergoes repeated distillation and purification, moderate starch is added into the extraction liquid, and the extraction liquid is dried to obtain powder which is reserved for use; thirdly, after some of amino acid, lysine, methionine, chitosan oligosaccharide and chitin, selected at random, are mixed, microelements, vitamins, plant enzyme, salt, edible oil, polysaccharide and protein powder are added in the obtained mixture, the mixture is packaged individually, wherein each bag contains one kilogram of the mixture, and the feed additive free of the antibiotics is obtained. The method for preparing the feed additive free of the antibiotics is easy, the ratio of the prepared additive is simple, obtained products do not have antibiotic additives which are replaced by natural extractives, and feed prepared with the feed additive reduces hormones or nutrition additive residues.

Description

A kind of preparation method of feed addictive of antibiotic-free

 

Technical field:

The present invention relates to field of feed, particularly a kind of preparation method of feed addictive of antibiotic-free.

 

Background technology:

In recent years along with the development of aquaculture, multiple feed addictive is come out one after another, improved the cultivation level and efficiency, the formation of feed generally comprises the grain major ingredient, composition auxiliary material and additive, additive mostly is chemicals, rich selenium for example, rich zinc, the products such as rich copper, perhaps vitamin, calcareous, glucose etc., its by by trace element with after multiannensional-sine mixes, be added in feed to guarantee the equilibrium of elemental composition in feed, but, some hormones of the employing that these feed addictives have, after chicken fowl is edible, become the products such as the chicken that obtains after broiler chicken or laying hen or egg, have hormone residues, human body is produced to certain impact.For prevent disease, raising efficiency of feed utilization, add the nutritive additives such as vitamin, trace element, amino acid in perfect compound feed, also add the non-nutritive additives such as antibiotic, mould inhibitor, flavor enhancement.The antibiotic medicine added in feed can cause pig, chicken to produce drug resistance, to the control of disease, bring a difficult problem; It is healthy that the problems such as while medicament residue also can affect people.Along with the raising of people's living standard and to the attention of food security, the research of antibiotic-free feed additive has become popular research topic.

Some national regulations of Europe ban use of antibiotic to solve the medicament residue problem in pig, chicken feed, add probiotic, enzyme preparation etc. to improve efficiency of feed utilization, have obtained effect in various degree.Therefore development of new feed addictive substitute antibiotics solution pig, chicken product drug residue problem and efficiency of feed utilization problem are current problems urgently to be resolved hurrily.For solving this technical problem, it is simple that the present invention aims to provide a kind of manufacture method, the additive formula made is simple, the product antibiotic-free additive made, the employing natural extract substitutes, use the feed of this additive configuration, reduced the preparation method of the feed addictive of the residual a kind of antibiotic-free of hormone or nourishing additive agent.

 

Summary of the invention:

The object of the invention is to overcome the shortcoming existed in prior art, provide a kind of manufacture method simple, the additive formula made is simple, the product antibiotic-free additive made, the employing natural extract substitutes, use the feed of this additive configuration, reduced the preparation method of the feed addictive of the residual a kind of antibiotic-free of hormone or nourishing additive agent.

To achieve these goals, the invention provides a kind of preparation method of feed addictive of antibiotic-free, wherein, comprise the steps:

A, prepare the step of organic Antibiotic Additive: choose the fresh leaf of bamboo or fresh mushroom, after after pulverizing, be placed in funnel, add the ethanolic solution that mass percent is 75%, hopper base arranges switch, after ethanolic solution did not have the leaf of bamboo or mushroom fully, so soak 3 days, opening switch, collect leaching liquor;

B, by steps A gained leaching liquor, distill repeatedly adds appropriate amount of starch after purifying, after oven dry pulvis, standby:

C: by amino acid, lysine, methionine, chitosan oligosaccharide, after any several mixing in chitin, add trace element, vitamin and phytoenzyme, salt, edible oil, polysaccharide, albumen powder, according to 1 bag of packing of per kilogram, obtain the feed addictive of antibiotic-free of the present invention after mixing.

 

The feed addictive of the antibiotic-free made through preparation method of the present invention wherein, configures following component according to parts by weight:

The nutritional labeling additive: 25-35 part,

Trace mineral supplement: 1-3 part,

Vitamin(e) supplement: 3-5 part,

Organic Antibiotic Additive: 3-6 part;

Enzyme additive: 5-8 part;

Described nutritional labeling additive is: amino acid, lysine, methionine, chitosan oligosaccharide, the mixture of any one or a few in chitin;

Described trace mineral supplement contains selenium, zinc, iron, molybdenum, copper various element;

Described vitamin(e) supplement is: the vitaminAD powder

Described organic Antibiotic Additive is extract solution of bamboo leaves or mushroom crop extract.

Further be added with following composition: salt 2-5 part, edible oil 3-5 part, polysaccharide 2-5 part, albumen powder 3-5 part.

Described organic Antibiotic Additive is prepared as pulvis from liquid and uses.

 

The invention has the beneficial effects as follows, manufacture method is simple, and the additive formula made is simple, and the product antibiotic-free additive made adopts natural extract to substitute, and has used the feed of this additive configuration, reduces hormone or nourishing additive agent residual.Feed addictive of the present invention, under the prerequisite without harm to animal and human body, can substitute exogenous hormones class additive fully, and successful; By add this feed addictive be equivalent to feed weight 0.2% in feed, under the prerequisite that does not increase forage volume, average every chicken 10-15 gram that can increase weight every day more, laying hen can be improved laying rate 10-20% more.

The present invention can promote appetite, raising efficiency of feed utilization, raising immunologic function, the prevent disease of pig, chicken.Be a kind ofly have no side effect,, green safety feed addictive to environment without any pollution residual without harmful components.For achieving the above object, the present invention adopts following technical measures, according to fungi extracts can activating immune system, promote lymphocyte transformation and propagation, antibacterium, antiviral, promote RNA, DNA, protein to synthesize etc., can improve animal immunizing power, promote growth of animal, reduce the death rate.The mannonase zytase can reduce enteron aisle chyme viscosity, destroys the plant cell wall construction, eliminates its anti-oxidant action, the systematic function oligosaccharides, improve intestinal microflora, be conducive to pig, chicken health, the material absorbing utilization that has additional nutrients, reduce the ight soil discharge.

 

The specific embodiment:

The preparation method of the feed addictive of antibiotic-free, wherein, comprise the steps:
