Description
Technical field
The invention belongs to technical field of fertilizers, and in particular to a kind of mixed feed for cray cultivation.
Background technique
Freshwater crayfish is the animal of typical omnivorousness.It had not only eaten green grass, water plant, but also ate grain trough and animal feeding
Material.The pure natural organics forage feed such as artificial propagation aquatic organism, toy and planting aquatic plants is taken, than the commodity of purchase
Feed palatability is good, full of nutrition, fresh delicious, can not have to purchase mixed feed completely.Both it can avoid because of commercial feed
The oxious components such as hormone are exceeded, guarantee commodity lobster green non-pollution, and can make the feed investment for saving writing every year.
Cray has become Important Economic breed variety in China in recent years, during commercial aquaculture, due to small dragon
For the environment of shrimp life by artificial limitation, cultivation density is also more much higher than wild stocks, therefore is easy to appear easy infection germ, life
How the problems such as life vigor declines, meat is poor improves the cultivation quality of cray, improves cultivation profit becomes currently one and asks greatly
Topic, many raisers expect improving breeding feed formula from breeding feed, so that cray growth is more healthy and strong, so
And the effect is unsatisfactory, mainly there is that assimilation effect is bad, palatability is bad, is also easy to produce the problems such as anorexia.
Summary of the invention
To solve the above-mentioned problems of the prior art, the present invention proposes a kind of mixed feed for cray cultivation,
The feed not only enhances cray immunity, improves survival rate, also has the advantages that palatability is good.
The technical scheme of the present invention is realized as follows:
A kind of mixed feed for cray cultivation, according to the number of parts by weight, including following raw material:
40~50 parts of corn flour, 4~8 parts of chicken meal, 20~30 parts of millet, 10~20 parts of dregs of beans, 10~20 parts of peanut meal,
15~25 parts of vinasse, 1~3 part of soybean lecithin, 4~8 parts of zeolite powder, 0.2~0.8 part of microelement and feed addictive
0.5~1.5 part；Wherein, the feed addictive mainly by Radix Astragali, Radix Codonopsis, cape jasmine, cortex acanthopanacis, Radix Angelicae Sinensis, Monochoria vaginalis, dried orange peel and
Pheretima obtains by fermentation of bacillus subtilis.
Preferably, the preparation method of the feed addictive, comprising the following steps:
1) according to the number of parts by weight, weigh each raw material: 15~25 parts of Radix Astragali, 15~25 parts of Radix Codonopsis, 10~20 parts of cape jasmine,
8~16 parts of cortex acanthopanacis, 8~16 parts of Radix Angelicae Sinensis, 5~10 parts of Monochoria vaginalis, 4~8 parts of dried orange peel and 4~8 parts of pheretima, it is spare；
2) after being mixed the raw material in addition to pheretima plus water carries out boiling, and filtrate and filter residue is obtained by filtration；Filter residue is put
Enter in beater and suitable quantity of water is added and carry out mashing processing, obtain slurries I, slurries I is warming up to 40~60 DEG C, is then added fine
It ties up plain enzyme to be digested, obtains enzymolysis liquid I；
3) pheretima is placed individually into beater and suitable quantity of water is added and carry out mashing processing, obtain slurries II, by slurries II
40~50 DEG C are warming up to, neutral proteinase is then added and is digested, enzymolysis liquid II is obtained；
4) merge filtrate, enzymolysis liquid I to obtain mixed liquor with enzymolysis liquid II, bacillus subtilis training is added into mixed liquor
Base is supported, bacillus subtilis is then inoculated with and ferments, fermentation temperature is 25~28 DEG C, and fermentation time is 15~20h, terminates hair
Fermentation liquid progress low temperature is concentrated to get medicinal extract by ferment.
It can not only efficiently use filtrate to feed addictive preparation method of the invention, and will general unused residue
It is utilized by digesting with fermentation, on the one hand makes fermentation obtain Chinese medicine additive and be easy to be digested and assimilated in cray body,
On the other hand also promote bacillus subtilis oneself expression secretion of phytase, amylase etc., so that additive inhibits fungal disease,
The poisonous and harmful substance in aquaculture pond is decomposed, improves the immunity and antiviral ability of cray, moreover it is possible to promote cray liver
The reparation of dirty chemical lesion.
Preferably, the additive amount of the bacillus subtilis is the 3~6% of the weight of the mixed liquor.
Preferably, the bacillus subtilis bacterium culture medium specifically: dregs of beans 10wt%, wheat bran 4wt%, urea 1.5wt%,
Yeast powder 2wt%, corn flour 8wt%, molasses 10wt%, magnesium sulfate 0.8wt%, add sterile water to 100wt%.
Preferably, the additive amount of the cellulase in step 2) is the 0.2~0.4% of slurries I weight.
Preferably, the additive amount of the neutral proteinase in step 3) is the 0.1~0.3% of slurries II weight.
Preferably, the microelement is one or more in manganese, silicon, boron, zinc, iron or magnesium.
The preparation method of mixed feed for cray cultivation of the invention: above-mentioned raw materials are weighed according to the proportion, are mixed
Uniformly, it then pelletizes at 80~90 DEG C.
Beneficial effects of the present invention:
1, the ingredients such as feed of the invention amino acid rich in, vitamin, minerals, microelement, contain there are many
Nutriment, formula science, nutrition is comprehensive, can not only maintain albumen and energy balance, but also can effectively facilitate lobster stomach and intestine
Road is wriggled, and help digestion air guide, improves appetite, and accelerates nuisance excretion, keeps lobster intestinal health, reduces lobster disease hair
Raw rate, to improve the yield of lobster.
2, according to the growth characteristic of cray, be susceptible to suffer from illness and feeding is accustomed to, feed addictive of the invention mainly selects
Natural, safety medicinal herb components, it then follows the configuration criteria of " monarch " has finally been determined through repetition test and verifying
The type and optimum amount of herbal medicine, so that it is wherein synergistic between various traditional Chinese medicine ingredients, it mutually promotes, has reached the small dragon of promotion
The reparation of shrimp chemical damage, the safety for improving liver function, the technical effect for improving immune, pre- disease prevention.In addition, additive
In contain pheretima, contain abundant protein and amino acid, especially by after neutral protein enzymatic treatment, the amino of release
Acid is more, wherein relatively being enriched and being matched rationally with necessary amino acid (LYS, METHILEU, THR, HIS etc.) content, it is easier to quilt
Cray absorbs.
