A kind of artifical compound feed of anti-grass carp fatty liver
[technical field]
The present invention relates to a kind of artifical compound feed, relate in particular to a kind of grass carp and can prevent the pathogenetic artifical compound feed of grass carp fatty liver of being used for.
[background technology]
The grass carp growth cycle is short, delicious meat, and aquaculture cost is low and parent that receive numerous raisers looks at.Grass carp all is one of maximum freshwater fish of breed amount in China.Yet usually the nutritional fatty liver disease can occur in the grass carp breeding process, thereby cause the grass carp decline of ingesting, poor growth, feed coefficient rises, and resistance against diseases descends, thereby causes other disease of grass carp easy infection.Especially at high temperature season, nutritional fatty liver can cause grass carp explosive dead.These are suffered from the sick grass carp of nutritional fatty liver carry out the pathologic dissection, can see on sense tissue and the mesenterium and deposit significant quantities of fat, the hepatic tissue steatosis is obvious, organizes vacuolation, the nucleus off normal, and cell volume increases, symptoms such as hepatic tissue hemostasis.Cause the sick reason of grass carp nutritional fatty liver a lot, comprise that feed nutrition is uneven, lack lipotropic factor in the man-made feeds, feed quality is low, breeding water body ecological deterioration etc.The feed of nutrient balance is difficult for causing fat in liver, to pile up, and the effect of lipotropic factor can be from reducing fat accumulation and fat in time transported the generation of avoiding fatty liver aspect two from the liver transfer liver.
Grass carp artifical compound feed on the market too asks most low-cost now, uses a large amount of low-quality feedstuffs, and feed nitrogen can be uneven, and some key trophic factors lack.It is sick to use such grass carp mixed feed the grass carp nutritional fatty liver usually to occur.Therefore, be necessary to provide a kind of artifical compound feed that prevents the grass carp fatty liver, prevent the economic loss that the grass carp fatty liver brings, promote feedstuff industry to develop in a healthy way.
[summary of the invention]
To the problems referred to above; The purpose of this invention is to provide a kind of annual grass carp nutritional fatty liver and many concurrent disease that causes and explosive death of grass carp that is prone at high temperature season that prevents; Thereby reduce grass carp fatty liver huge financial loss, can promote grass carp growth, artifical compound feed balanced in nutrition.
For realizing above-mentioned purpose, the technical scheme that the present invention taked is following:
A kind of artifical compound feed of anti-grass carp fatty liver comprises the component of following weight portion: dusty yeast 1-5 part, dregs of beans 5-10 part, dish dregs of rice 30-40 part; Cotton dregs 5-15 part, wheat 10-15 part, DDGS (maize alcohol lees and DDGS thereof) 5-15 part, calcium dihydrogen phosphate 0.5-2 part; System chaff 5-15 part, soya-bean oil 0.5-2 part, bentonite 1-10 part, Choline Chloride 0.1-0.3 part; Many ore deposits of multidimensional premix 0.5-2 part, anti-oxidant 0.01-0.05 part, salt 0.1-0.3 part, mould inhibitor 0.05-0.3 part; Methionine 0.01-0.05 part, soybean lecithin 0.1-1 part, bile acid 0.02-0.2 part, oriental wormwood 1-3 part.
In a preferred specific embodiment, comprise the component of following weight portion: 2 parts of dusty yeasts, 10 parts of dregs of beans, 30 parts of the dish dregs of rice, 10 parts of cotton dregs; 15 parts of wheats, 10 parts of DDGS (maize alcohol lees and DDGS thereof), 1 part of calcium dihydrogen phosphate, 15 parts of system chaffs, 1.5 parts in soya-bean oil; 2.95 parts of bentonites, 0.15 part of Choline Chloride, 0.6 part of many ore deposits of multidimensional premix, 0.2 part of salt, 0.02 part of anti-oxidant; 0.1 part of mould inhibitor, 0.02 part of methionine, 0.5 part of soybean lecithin, 0.02 part of bile acid, 1 part of oriental wormwood.
In another preferred specific embodiment, comprise 5 parts of dusty yeasts, 10 parts of dregs of beans, 33 parts of the dish dregs of rice, 6 parts of cotton dregs; 15 parts of wheats, 9 parts of DDGS (maize alcohol lees and DDGS thereof), 1 part of calcium dihydrogen phosphate, 15 parts of system chaffs, 1 part in soya-bean oil; 2.9 parts of bentonites, 0.15 part of Choline Chloride, 0.6 part of many ore deposits of multidimensional premix, 0.2 part of salt, 0.02 part of anti-oxidant; 0.1 part of mould inhibitor, 0.02 part of methionine, 0.5 part of soybean lecithin, 0.02 part of bile acid, 1.5 parts of oriental wormwoods.
After above-mentioned raw materials mixing pulverizing, mix in proportion, through feed manufacturing machine, promptly get the present invention's manual work mixed feed after the extruding cutting.
Compare with normal diet, the artifical compound feed of the anti-grass carp fatty liver of the present invention has following advantage: the oriental wormwood that 1, contains in the feed can effectively prevent the generation of grass carp fatty liver; 2, contained bile acid can promote fat to transport from careless internal organ transfer in the feed, thereby effectively prevents the generation of grass carp fatty liver; 3, balanced in nutrition, grass carp ingests the back growth rapidly, and premunition is strong.
[specific embodiment]
Below in conjunction with specific embodiment the present invention is described further.
