Description

Sturgeon feed and preparation method thereof
Technical field
The invention belongs to field of feed, and in particular to a kind of sturgeon feed and preparation method thereof.
Background technique
Sturgeon is the first-class delicious food in food by the favorable comment of numerous gourmets with delicious meat, full of nutrition. In the world, the U.S., Germany are begun to study the artifical compound feed of sturgeon by five sixties, China's researcher Also it in the research for the artifical compound feed for having started special aquatic products the seventies and eighties, makes great progress, it is effective to promote The development of the cultivation of sturgeon.But in some critical higher technical formulas of scientific and technological content and process flow, not yet Obtain more quantum jump.
During the artificial breeding of sturgeon, the disease incidence of sturgeon is higher, and the common disease of sturgeon has ovum mildew, water mold Disease, hemorrhage, bacillary enteritis, swollen mouth disease, trypanosomiasis, trichodinasis, chilodoniasis, ich, gyrodactyliasis, quasi- Horse Neck Argulosis, hepatic encephalopathy, Histopathology disease, epicardial fat knit scorching, black matrix disease, pregnant disease and red spot disease etc., for The fungal disease of sturgeon, control method are that fish body to be prevented is injured, can be using clotrimazole and 1% salt to illness fish body Suffer from fish 10 minutes or so with the immersion of sodium bicarbonate water mixed solution.For the bacteriosis of sturgeon, control method be first have into It acts charitably environment disinfected, while adding multi-vitamins and immune polysaccharide in feed, for improving the immunity of fish body；It can also be with Add antibiotic and the Chinese herbal medicine prevention of noresidue in right amount in feed.Using existing disease prevention and cure method to the disease of sturgeon It is prevented and treated, although the survival rate of sturgeon can be improved to a certain extent, the disease of sturgeon is mostly explosive disease, is had Extremely strong infectiousness, morbidity is swift and violent, causes the death rate of sturgeon higher, and the survival rate of sturgeon also only has 62~65%.Therefore, it mentions The survival rate of high sturgeon is most important for the development of sturgeon cultivation industry.
Summary of the invention
The present invention proposes a kind of sturgeon feed, which not only meets the nutritional need of sturgeon, also improves depositing for sturgeon Motility rate improves the digestive utilization ratio of plant phosphorus.

2) filter residue of step 1) is put into beater and suitable quantity of water is added and carry out mashing processing, obtain slurries；
3) into the slurries of step 2), inoculated aspergillus niger is fermented with saccharomyces cerevisiae, and fermentation temperature is 28~32 DEG C, hair The ferment time is 20~26h, terminates fermentation, and fermentation liquid progress low temperature is concentrated to get medicinal extract, sprays modified kaolin to medicinal extract, then It is dried to obtain Chinese herbal medicine extract；The mass ratio of medicinal extract and modified kaolin is 1:6~12, the inoculum concentration of aspergillus niger is The 2~4% of slurry weight, the inoculum concentration of saccharomyces cerevisiae are the 1~3% of slurry weight.
Preferably, the modified kaolin is prepared by the following method to obtain：
Kaolin is added to the water to obtain dispersion liquid, starch is then added into dispersion liquid, stir, be warming up to 70 DEG C~ 85 DEG C are added nano silica thereto again and carry out ultrasonic disperse with silane coupling agent and stir, dry after reaction terminates ?.
Preferably, the mass ratio of the kaolin, the starch and the nano silica is 20~30:5~7:1 ~3, the mass ratio of the nano silica and the silane coupling agent is 16~20:1.
Preferably, the silane coupling agent is silane coupling A -171, Silane coupling agent KH550 or silane coupling agent KH560。
Preferably, the premix is the mixed of glycine, isoleucine, tea polyphenols, apple polyphenol and starch from sweet potato composition Close object.
Preferably, the multi-vitamins are VitAVitE, vitamin B, vitamin B2 and niacin composition Mixture.
It is a further object to provide a kind of preparation methods of sturgeon feed, include the following steps：
1) fermented bean dregs, rapeseed dregs, wheat bran, cuttlefish meal, soybean lecithin, corn protein powder and zeolite are weighed according to the proportion Powder mixing is crushed, and crushed mixture is obtained；
2) after weighing additive, premix, multi-vitamins and fish oil mixing according to the proportion, then it is mixed with the crushing of step 1) Close object carry out it is uniformly mixed, then through 80~85 DEG C of vapor pelletization system pelletize.
Beneficial effects of the present invention：
1, selection of the invention is mainly by tealeaves, pueraria lobata, honeysuckle, oriental wormwood, garlic and dried orange peel by aspergillus niger and wine brewing The additive that yeast fermentation is prepared, it then follows the configuration criteria of " monarch " has finally been determined through repetition test and verifying The type and optimum amount of Chinese herbal medicine, so that it is wherein synergistic between various traditional Chinese medicine ingredients, it mutually promotes, has reached enhancing fish The immunity of body, the incidence for reducing disease.
2, traditional Chinese medicine is boiled the dregs of a decoction (being filter residue in the present invention) for extracting and giving it up by the present invention, at mashing Reason, then handled with aspergillus niger and fermentation by saccharomyces cerevisiae, one side can sufficiently by the ingredient of dregs of a decoction raw material itself, (ingredient be also Have the non-principal component not having in traditional water and alcohol extract) it decomposites and, on the other hand promote aspergillus niger and saccharomyces cerevisiae itself Secretion of phytase is expressed, so that the phytase in the Chinese herbal medicine extract finally obtained, which is able to enter in fish body, helps fish digestion Absorb plant phosphorus.
3, the present invention coats Fermented Condensed liquid using modified kaolin, makes which reduce high temperature to aspergillus niger and wine brewing The influence of the enzyme activity of the phytase of yeast secretary, activity are high.In addition, kaolin is even by starch, nano silica and silane Join the modification of agent, so that kaolin coats Fermented Condensed liquid, enters in fish body and can release rapidly by the dry additive obtained It puts, plays the activity of phytase.
