Description
Technical field
The present invention relates to a kind of loach feed, belongs to technical field of aquaculture more particularly to a kind of can improve loach body
Color and the mixed feed for improving cultivation survival rate.
Background technique
Loach (scientific name:Misgurnus anguillicaudatus), belong to Cobitidae Misgurnus.With fast growing, disease-resistant
Advantages, the delicious meats such as power is strong, cultivation density is high, individual big, the culture-cycle is short, easy fishing have high nutritive value, quilt
It is described as " ginseng in water ", therefore welcome and consumers by raiser.
In recent years, with the expansion of loach breeding scale, seedling degradation phenomena is more serious in the market, and the body colour cultivated out is inclined
Black, disease is more, and survival rate is low, and the quality requirement of mixed feed is also continuously improved.
Therefore, how to develop it is a kind of can improve loach body colour, and improve the mixed feed of cultivation survival rate, be current
Field technical staff technical problem urgently to be resolved.
Summary of the invention
In order to solve the above technical problems, the object of the present invention is to provide a kind of nutrition equilibrium, can effectively improve loach body
Color, the mixed feed of strengthen immunity can reduce the disease incidence of loach seedling, improve the survival rate of cultivation.
It is a further object to provide a kind of above-mentioned mixed feeds that can improve loach body colour and improve survival rate
Preparation method.
The purpose of the present invention is what is be achieved by the following technical programs：
A kind of mixed feed that can improve loach body colour and improve survival rate, it is yellow added with natural leaf in the mixed feed
Element.
Furthermore, the natural carotenol of 0.2-0.4% is added in the mixed feed.
A kind of mixed feed that can improve loach body colour and improve cultivation survival rate proposed by the present invention, by following quality hundred
Divide the raw material components composition of content proportion：
Fish meal 3-6%, dregs of beans 15-20%, Strong flour 18-22%, corn protein powder 5-10%, rapeseed dregs 10-12%,
Peanut cake 5-7%, dephenolization cottonseed protein 10-15%, shrimp shell meal 6-8%, cuttlefish cream 4-6%, fodder yeast 4-6%, di(2-ethylhexyl)phosphate
It is hydrogen calcium 1-2%, soyabean lecithin oil 3-4%, fish oil 1-2%, vitamin premix 1-2%, mineral salt premix 1-2%, natural
Lutein 0.2-0.4%.
Mixed feed of the invention, the right lutein is extracted by raw material of marigold flower, specific steps
For：
1) at granular marigold particle in chloroform-ethanol mixed solvent (feed liquid weight percent 1:10) immersion
Under, in a solvent by the pigmentolysis in particle, form miscella；
2) mixing well cuts are separated in filtering；
3) by miscella solvent and ointment separate, it is different using both solvent and ointment boiling point, by miscella
In solvent be evaporated；Ointment enters destilling tower, using the effect of vacuum pump, realizes negative pressure evaporation at 38 DEG C of temperature, will
The solvent remained in ointment carries out last separation；It is thick lutein through treated ointment；
4) above-mentioned substance is entered into treatment tank and is refined into finished product.
Mixed feed of the invention, the vitamin premix are uniformly to mix following ingredients (g/kg mixed feed)
Mixture：
Vitamin A：16, vitamin D：10, vitamin E：1, vitamin K：2.5, vitamin B1：4, vitamin B2：5, it ties up
Raw element B6：5, pantothenic acid：20, biotin：1, choline：150, folic acid：10, inositol：200, calcium pantothenate：70, vitamin B12：1, it takes off
Rouge rice bran：504.5.
Mixed feed of the invention, the mineral substance premix are uniformly to mix following ingredients (g/kg mixed feed)
Mixture：
Calcium dihydrogen phosphate：500, potassium chromium sulfate：5, copper sulphate：4, ironic citrate：10, magnesia：26, manganese sulfate：5, single
Water citric acid potassium：250, potassium sulfate：50, sodium chloride：50, zeolite powder：100.
In addition, the present invention also provides a kind of preparation sides of mixed feed that can improve loach body colour and improve survival rate
Method, including step in detail below：
1) raw material it is clear it is miscellaneous after, accurately weigh each component in raw material, be then uniformly mixed；
2) raw material mixed is crushed by micronizer, makes it through 200-300um sieve；
3) then material is moved into modulator, is passed through 90-100 DEG C of steam and modulates 5-6 minutes, then at 95-100 DEG C
Under carry out extruding granulation；
4) feed granules are dried under the conditions of 85-90 DEG C；
5) it will be packed after the pellet cooling after drying.
By above-mentioned technical proposal, the present invention has following advantageous effects：
1) the problems such as present invention is relatively low for the artificial breeding partially black cultivation survival rate of loach body colour, with jade in loach feed
Rice gluten powder is added to natural carotenol as feedstuff.
2) corn protein powder contains the natural pigment for being conducive to improve loach body colour；Natural carotenol is to be with marigold flower
Raw material extracts lutein, is conducive to the coloring of loach body colour.
3) in addition, natural carotenol is a kind of excellent antioxidant, can resist free radical caused in fish body cell with
Organ damage, to improve fish body immunity.Culture experiment the result shows that, mixed feed provided by the invention is able to satisfy loach
Basic nutrition demand, can be obviously improved the body colour of loach, moreover it is possible to effectively enhance its immunity, to improve cultivation survival rate.
Specific embodiment
The present invention is further described combined with specific embodiments below.
The invention discloses a kind of mixed feed that can improve loach body colour and improve survival rate, add in the mixed feed
The natural carotenol for being 0.2-0.4% added with weight percent；It also include each raw material component of following weight percent：
