A kind of duckbilled sturgeon feed reducing the incidence of disease
Technical field
The invention belongs to agriculture field, particularly a kind of duckbilled sturgeon feed reducing the incidence of disease.
Background technology
Duckbilled sturgeon, formal name used at school U.S. paddlefish.Mainly with earthworm, shrimp and planktonic organism for food, because its form is special, kiss long and flat, as duckbilled, like paddle, therefore gain the name.Duckbilled sturgeon (paddlefish) originates in U.S. Mississippi Valley, just live on earth from (i.e. dinosaur period) before 300,000,000 years, and the rare sturgeons of the one remained, be one of only two kinds in Polyodontidae in the world.Paddlefish in it and mandarin sturgeon and Water area of Changjiang River belongs to Gadiformes paddlefish section together, is one of superfine product fish in fish.
At present, several large problem is there is: first in the cultural technique of duckbilled sturgeon, under China's aquaculture is mostly hydrostatic pool environment, high-density breeding causes the precipitations such as a large amount of aquatic livestock excretas, remaining bait, disinfectant water-bed, then be decomposed and discharge a large amount of harmful substance, make the increase of aquaculture water cultivation density, water body environment worsens, the farming disease harms also increasingly sharpens, and many diseases are serious threat culture benefit.And the loss of feed in water and excremental accumulation have become the primary pollution source of water body, cause water quality deterioration, pathogen amount reproduction, survival rate declines, and dosage increases, and changes water frequent, and then causes aquaculture cost to rise.Therefore, the quality of feed and utilizability are that can culture fishery one of the important restriction factor of sustainable development.
Summary of the invention
Goal of the invention: in order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of duckbilled sturgeon feed reducing the incidence of disease.

Present invention also offers a kind of preparation method reducing the duckbilled sturgeon feed of the incidence of disease, comprise the following steps:
(1) get garlic, onion, dandelion, grass-leaved sweetflag, oriental wormwood, the stem of noble dendrobium pulverize respectively, mixing, obtains just batch mixing;
(2) fish meal, freshwater shrimp powder, pork liver powder, Kelp Powder, dregs of beans, Chinese sorghum part, soy meal, pearling cone meal, cotton dregs, the dish dregs of rice, wheat bran, clam worm powder, wheat time powder, alfalfa meal, phosphatide, seawood meal, medical stone powder is got, after mixing, add vegetable oil, stir, obtain compound;
(3) in compound, add just batch mixing, stir, to obtain final product.
Beneficial effect: duckbilled sturgeon provided by the invention can not only provide duckbilled sturgeon basal nutrient material, ensure the growth efficiency of duckbilled sturgeon, simultaneously by optimizing feed formula add core additive, the meat of duckbilled sturgeon can also be improved, security is high, raw material sources are wide, cheap.
Containing multiple nutrients material in duckbilled sturgeon feed of the present invention, scientific formulation, comprehensive nutrition, can meet the basal nutrient of duckbilled sturgeon completely.
Duckbilled sturgeon feed of the present invention can improve duckbilled sturgeon immunity, security is high.Adopt natural products be raw material as core additive, duckbilled sturgeon autoimmunity can be improved, promote the growth of duckbilled sturgeon, improve duckbilled sturgeon meat.
Duckbilled sturgeon feed provided by the invention is easy to use, abundant raw material source, cost are low, has and without special odor, accompanies in feed and do not affect feeding; Easy to use, it is convenient to preserve.
