Description
Technical field
The present invention relates to a kind of compound feed of pelteobagrus fulvidraco juvenile fish and preparation method thereof.
Background technology
The Pelteobagrus fulvidraco formal name used at school
Pelteobagrus fulvidraco(Richardson), popular name Huang Lading, yellow bud are first-class, in China each waters, the whole nation except that western plateau distribution are arranged all.Pelteobagrus fulvidraco body bluish yellow look, most irregular brown speckle of tool, each fin ash black-tape is yellow, fine and tender taste, its muscle nutrition is abundant, stings between no flesh, and meat flavour is delicious, and edible ratio height is a kind of typical euryphagy fish, and economic worth is high.For a long time, Pelteobagrus fulvidraco is little because of individuality, and is many as small-sized wild fishes class processing by people.The Along with people's growth in the living standard; Consumption to aquatic products changes to " quality leading type " rapidly; Thereby the economic worth to many aspects such as Pelteobagrus fulvidraco nutritive values is re-recognized; So from the hot-sale products of how much " taking off heap " and dump about 30 yuan of per kilograms till now in past, not only domestic market demand enlarges, and has exported states such as Korea S, Japan.But because Pelteobagrus fulvidraco breeding potential in natural waters is lower, the speed of growth is slow, lean on the wild Pelteobagrus fulvidraco of fishing in the natural waters can't satisfy the demand in market, so various places is propagated Pelteobagrus fulvidraco artificially as a kind of economic fish.Present propagating artificially regional Pelteobagrus fulvidracos such as Guangdong Province, Zhejiang Province has certain scale, and still, Pelteobagrus fulvidraco is propagated artificially and still has some technical problems, and cultural technique is prematurity still.Use the fish meal on the market to feed Pelteobagrus fulvidraco now; Fish body survival rate, rate of body weight gain is on the low side, and causes the Pelteobagrus fulvidraco body colour to shoal (bleaching) easily, and Pelteobagrus fulvidraco is in natural water; Be rich in the algae and the planktonic organism of carotenoid in a large number owing to ingested; Body colour is more bright-coloured, and there is blackspot on the side under the normal condition, and remainder is yellow.The factor that the Pelteobagrus fulvidraco body colour changes the most important thing is that feed substances has produced great influence to its body colour except that factor affecting such as waters environmental condition, disease, the Pelteobagrus fulvidraco body colour shoals and had a strong impact on the quality of Pelteobagrus fulvidraco as aquatic products.Therefore, the exploitation of yellow-head catfish feed, the particularly exploitation of parr of yellow catfish feed are the needs of Pelteobagrus fulvidraco aquaculture development.
Summary of the invention
The purpose of this invention is to provide a kind of compound feed of pelteobagrus fulvidraco juvenile fish and preparation method thereof.This mixed feed has characteristics such as high-quality grinding particle size, mixture homogeneity, feed formability and resistance to water, can improve the absorption rate of feed, and it is applicable to that the body weight of feeding is the Pelteobagrus fulvidraco of 5～50 grams; Can satisfy the nutritional need of the parr of yellow catfish of body weight 5～50 grams, it is rich in the additive of pigementation, and the Pelteobagrus fulvidraco body colour that makes breed is near natural effect; And the resistance against diseases of raising fish; Promote that the fish body is quick, healthy growth, shorten the culture-cycle greatly, significantly reduce to use and even do not use fresh and alive feed; Reduce aquaculture cost; Reduce pathogeny and water pollution, and the preparation method is scientific and reasonable, has remarkable economic efficiency and environmental benefit.
Compound feed of pelteobagrus fulvidraco juvenile fish of the present invention comprises following component by weight percentage: fish meal 25%～45%, meat meal tankage 4%～8%, flour 15%～20%; Corn 4%～10%, dregs of beans 10%～20%, rapeseed dregs 4%～8%, fish oil 1%～4%; Corn protein powder 10%～20%, multidimensional 1.0%, many ore deposits 1.0%, immunopotentiator 0.1%; Liver protectant 0.2%, choline 0.2%～0.4%, calcium dihydrogen phosphate 1%～2%.
A kind of process for preparing compound feed of pelteobagrus fulvidraco juvenile fish, step is following:
(1) feeds intake, pulverizes, carry out mixed once;
(2) deironing, pulverizing are carried out secondary and are mixed;
(3) modulation, expanded granulation;
(4) oven dry, grease spraying make compound feed of pelteobagrus fulvidraco juvenile fish after the cooling;
(5) again through oven dry, grease spraying, make compound feed of pelteobagrus fulvidraco juvenile fish after the cooling.
Remarkable advantage of the present invention is:
The present invention is according to parr of yellow catfish nutritional need and Physiology and biochemistry characteristics; Select quality raw materials for use; Optimize the feed formula structure; Add the compound feed of pelteobagrus fulvidraco juvenile fish that efficient green immunity growth-promoting additive is developed, use this mixed feed can reduce aquaculture cost, reduce disease and take place and water pollution.
The present invention selects for use corn and corn protein powder etc. as raw material according to Pelteobagrus fulvidraco body colour regulation mechanism, helps the additive of pigementation, and the Pelteobagrus fulvidraco body colour that makes breed is near natural effect.
Reasonably combined each raw material components of the present invention adds efficient green immunity growth-promoting additive, improves technology; Reduce the destruction that high temperature causes feed nutrient in the preparation process, and guaranteed the stability of feed in water, increased the energy level in the feed simultaneously; Make the feed of preparing have characteristics such as high-quality grinding particle size, mixture homogeneity, feed formability and resistance to water, improved the absorption rate of feed, can satisfy the nutritional need of parr of yellow catfish; And improve the resistance against diseases of fish, and promote that the fish body is quick, healthy growth, shorten the culture-cycle greatly; Significantly reduce to use and even do not use fresh and alive feed, reduce aquaculture cost, reduce pathogeny and water pollution; And the preparation method is scientific and reasonable, has remarkable economic efficiency and environmental benefit.
