Description
Technical field
The present invention relates to technique for producing feed field, a kind of Composite fermentation type microbiological feed and its preparation side are particularly belonged to
Method.
Background technique
Since aquaculture excessively pursues high density, high yield, it is bound to cause breeding pollution object and increases and accumulate, cause to cultivate
The gradually deterioration of environment, major embodiment are as follows: water pollution;Air pollution;Pathogenic microorganism, which is largely bred, to spread the disease;Drug is residual
It stays;Pollution etc. of the microelement excess emissions to environment directly contributes cultivation failure and threatens Product quality and safety.According to current
The national appearance in relation to relevant policies such as food safety, environmental protections, development & production green, efficient, health, nonreactive microorganism
Feed, feed addictive, microbe additive, enzyme preparation become a key subjects of the pendulum in face of current cultivation every profession and trade.
Current microbiological feed is at high cost due to fermentation raw material, causes Feed Manufacturing at high cost, is unfavorable for extensive
Industrialization production is not suitable with the demand in market.
Summary of the invention
The object of the present invention is to provide a kind of Composite fermentation type microbiological feeds, overcome the deficiencies in the prior art, make
The garlic stalk and ginkgo leaf residue for using low cost reduce the production cost of feed, meet industrialization production as fermentation raw material
Demand.
To solve the above problems, the technical solution used in the present invention is as follows:

Stalk, ginkgo leaf residue and wheat bran, it is dregs of beans 30%- that each substance component, which accounts for the weight percentage of culture medium, in the culture medium
55%, garlic stalk 10%-25%, ginkgo leaf residue 10%-20%, wheat bran 15%-40%.
Further, including strain raw material and culture medium, the strain raw material by bacillus subtilis and lactobacillus plantarum it
One of or both arbitrary proportion combine;It include dregs of beans, garlic stalk, ginkgo leaf residue and wheat bran in the culture medium,
It is dregs of beans 41%, garlic stalk 17%, ginkgo leaf residue that each substance component, which accounts for the weight percentage of culture medium, in the culture medium
15%, wheat bran 27%.
Further, the overall viable bacteria content of the strain raw material is 5 × 108-10×109cfu/ml。
A kind of preparation method of Composite fermentation type microbiological feed, it is characterised in that: include the following steps,
(1) preparation of culture medium: claiming according to the weight percentage of dregs of beans in formula, garlic stalk, ginkgo leaf residue and wheat bran
Raw material is taken, above-mentioned raw materials are put into grinding device respectively and are crushed, is uniformly mixed after crossing 40 meshes, solid is made in sterilizing
Culture medium;
(2) actication of culture: being inoculated into LB culture medium for bacillus subtilis and activate, and lactobacillus inoculum to MRS is trained
Feeding base is activated;
(3) strain is inoculated with: the strain raw material activated in step 2 is inoculated into step 1 according to inoculum concentration for 8%-10%
On the solid medium of preparation;
(4) solid state fermentation: inoculated solid medium is placed into Zymolysis Equipment, under the conditions of 30-35 DEG C of temperature,
