Abstract
The present invention relates to a kind of rainbow trout culturing feed and its application, which includes the raw material of following parts by weight：30-40 parts of red fish meal, 15-20 parts of euphausia superba powder, 1.5-4 parts of dregs of beans, 5-7 parts of soya-bean oil, 5-7 parts of fish oil, 1-3 parts of soybean lecithin, 15-25 parts of wheat flour, 3-6 parts of powdered rice hulls, 1-2.5 parts of vitamin premix, 1.5-2.5 parts of mineral pre-mix, 0.2-0.3 parts of choline chloride, 0.5-2 parts of calcium dihydrogen phosphate；The rainbow trout culturing feed can satisfy the various nutritional needs of rainbow trout, and promote absorption and utilization of the rainbow trout to nutriment, is conducive to rainbow trout growth and develops, has lower feed coefficient；In addition, the feed can improve the muscle color of rainbow trout, effectively solves the problems, such as that cultivation rainbow trout muscle red degree is relatively low, improve commodity value.
Description
Technical field
The present invention relates to rainbow trouts to raise field, in particular to a kind of rainbow trout culturing feed and its application.
Background technique
Belong to vertebrate rainbow trout (Oncorhynchus mykiss) subphylum, Osteichthyes, salmon shape mesh, salmonidae, salmon category,
It is known as " ginseng in water ", is a kind of cold water fishes, is one of widest worldwide cultured fishes.Rainbow trout eats
Value makes its muscle red degree become the important indicator for evaluating its quality；However, existing cultivation rainbow trout muscle red degree by
It gradually reduces, reduces the degree of recognition of consumer, influence its economic value.
Currently, the change of rainbow trout muscle red degree is mainly by adding corresponding pigment in feed, however, feed
The pigment of middle application is usually chemical industry synthesis, expensive, and since pigment is added in feed merely to improving meat
Color without other trophic functions, therefore considerably increases feed cost.In addition, the chemical property of these pigments itself is unstable
Fixed, commercial form need to usually carry out coating or microcapsules processing, enhance its stability, different capsulating material meetings to block air
The digestion and absorption and utilization for influencing pigment, influence biological value.
In view of this, the present invention is specifically proposed.
Summary of the invention
The first object of the present invention is to provide a kind of rainbow trout culturing feed, which can satisfy the various nutrition of rainbow trout
Demand, and promote absorption and utilization of the rainbow trout to nutriment, conducive to the growth and development of rainbow trout, there is lower feed system
Number；In addition, the feed can improve the muscle color of rainbow trout, effectively solve the problems, such as that cultivation rainbow trout muscle red degree is relatively low,
Improve commodity value.
The second object of the present invention is to provide a kind of rainbow trout method for breeding, and the method increase raising rainbow trout muscle Prawns
The deposition content of green element, improves the red degree of rainbow trout muscle, and can promote the growth and development of rainbow trout, reduced feed
Coefficient.
In order to realize above-mentioned purpose of the invention, spy uses following technical scheme：
The first aspect of the present invention provides a kind of rainbow trout culturing feed, which includes the original of following parts by weight
Material：30-40 parts of red fish meal, 15-20 parts of euphausia superba powder, 1.5-4 parts of dregs of beans, 5-7 parts of soya-bean oil, 5-7 parts of fish oil, soybean lecithin
1-3 parts, 15-25 parts of wheat flour, 3-6 parts of powdered rice hulls, 1-2.5 parts of vitamin premix, 1.5-2.5 parts of mineral pre-mix,
0.2-0.3 parts of choline chloride, 0.5-2 parts of calcium dihydrogen phosphate.
The present invention can satisfy the various nutritional needs of rainbow trout by the selection of above-mentioned specified raw material and dosage, and promote
Absorption and utilization of the rainbow trout to nutriment have lower feed coefficient conducive to the growth and development of rainbow trout；In addition, the feeding
Material can improve the muscle color of rainbow trout, effectively solve the problems, such as that cultivation rainbow trout muscle red degree is relatively low, improve commodity value.
Red fish meal refers to fish meal made of the fish with the red flesh of fish；Its primary raw material includes silver carp, sardine, wind tail
Leftover bits and pieces etc. after fish, green peel fish and other various small fish, fishes and shrimps food processing；Preferably, red fish meal in the present invention
Main composition content is crude protein 71%-73%, crude fat 8.5%-10.5%.
Euphausia superba powder is rich in protein, fat content appropriateness, while carotenoid rich in, can improve feeding
The palatability of material；In addition, euphausia superba powder amino acid nutrient balances, including 10 kinds of essential amino acids needed for fish growth
(EAA) and 8 kinds of nonessential amino acid, and content of polyunsaturated fatty acid and fish meal are substantially suitable；To krill in the present invention
The main composition content of powder does not limit strictly, it is preferable that in the euphausia superba powder content astaxanthin be 150-250mg/Kg,
Water content is 11%-13%, crude protein content 63%-65%, crude fat content 6%-8%, content of ashes 13%-
15%, fluorine content 1.55%-1.65%.
Dregs of beans is the byproduct that soybean obtains after extracting bean oil, also known as Soybean Meal.Answering there are many containing in Soybean Meal
With substance, wherein protein content accounts for 45%~52% or so, also contains a large amount of oligosaccharide, polysaccharide and cellulose.
Soya-bean oil is the grease extracted from soybean, has certain viscosity, is translucent liquid, and color is because big
Beans kind skin and soybean varieties are different and different, from light yellow to dark brown, have soy flavor；In soya-bean oil comprising palmitinic acid, oleic acid,
Stearic acid, linoleic acid, arachidic acid and linolenic acid can provide fat content abundant for rainbow trout and be conducive to astaxanthin in rainbow trout
Intracorporal deposition.
Fish oil is the general designation of the intracorporal whole oily substances of fish, it includes body oil, liver oil and cerebrol, main fish oil be it is a kind of from
The grease that greasiness fish are extracted, is polyunsaturated fatty acid (DHA and EPA) rich in ω -3, has the health such as anti-inflammatory, adjusting blood lipid
Benefit.
Soybean lecithin is the byproduct during refined soybean oil, is passed through after being then centrifuged for separation by solvent extraction
Alcohol is washed to obtain；Soybean lecithin is capable of providing choline and fatty acid, conducive to the growth and development of rainbow trout.
Wheat flour through wheat grind processing after to obtain the final product, in wheat flour rich in protein, carbohydrate, vitamin and
The minerals such as calcium, iron, phosphorus, potassium, magnesium have the effect of relieving mental strain and strengthening the kidney, invigorating the spleen thickness intestines, heat extraction quench the thirst；Energy can be provided for rainbow trout
And various nutriments.
Powdered rice hulls and crush to obtain by rice husk, mainly contain cellulosic and ash content, also containing a small amount of crude protein and
Fat；Rainbow trout can be promoted to promote making full use of for nutritional ingredient to the digestion and absorption of nutriment.
Choline chloride white hygroscopic crystalline, it is tasteless, there is fish stench, the absorption of nutriment can be promoted, promotes growth
Development, and its bad smell for distributing, can preferably stimulate the smell of rainbow trout, improve the utilization rate of feed.
The vitamin type of vitamin premix is not limited strictly in the present invention, it is preferable that the vitamin premix
Object includes vitamin A >=2KIU/kg, vitamin E >=20mg/kg, Vitamin K3 >=0.5mg/kg, vitamin B1, vitamin B2
>=4mg/kg, vitamin B6 >=4mg/kg, niacinamide >=15mg/kg, calcium pantothenate >=5mg/kg, L-AA -2- phosphate
≥75mg/kg；The idiotrophic demand that can satisfy rainbow trout by the addition of vitamin premix promotes the growth of rainbow trout to send out
It educates.
