Abstract
The present invention relates to special feed additive for seawater fish and a preparation method thereof, belonging to the technical field of aquatic feed additives. The special feed additive for seawater fish consists of the following raw materials: 2-10 parts of fish oil DHA, 5-15 parts of fish oil EPA, 45-55 parts of linseed oil, 30-38 parts of soybean oil and 1-5 parts of vitamin E. The total fatty acid content weight ratio of the fish oil DHA and fish oil EPA is greater than 1, the total fatty acid content percentage of long chain n-3 and short chain n-3 is less than or equal to 50% and the total fatty acid weight ratio of the n-3 and n-6 is more than or equal to 2. The preparation method is as follows: 1) weighing the fish oil EPA and fish oil DHA and putting the weighted fish oil EPA and DHA into an intelligent temperature controlled blender to conduct mixing for a first time; 2) adding the vitamin E into the mixture to conduct mixing for a second time; 3) adding the linseed oil and soybean oil to conduct mixing for a third time; and 4) performing sub-packaging and labeling and preserving the finished product at 4-8 DEG C. A vacuum spraying technology is used to envelope the feed additive on the compound feed. The anti-stress effects of the unsaturated fatty acid and VE are utilized, and by blending and mixing the raw materials, and enveloping the feed additive on the dry particles by spraying, the feed has anti-stress and attractant functions, improves feed efficiency, and is safe, high-efficient and free of non-toxic and side effects.
Description
One, technical field:
The present invention relates to a kind of fish feed additive special and preparation method thereof, is specifically by allocating nutrient and produce the special anti-stress feed addictive of marine fish culture in conjunction with feed manufacturing spraying film-coating technique, belonging to feeding additive aquatic animal technical field.
Two, background technology:
Under the situation of modern intensive production development, the intrinsic biology demand such as behavior, nutrition, psychology of aquatic animal is subject to severe challenge under cultivating condition, moreover the aggravation of Human Activities on Natural Ecology environmental disruption in addition, when fish body can not be escaped and cannot overcome these destructive stimuluses, stress reaction is just more outstanding to the harm of fish body.Meanwhile, the improper use of some additives, the problem such as result in the resistance to the action of a drug of aquatic livestock and drug disposition is residual, directly jeopardizes the health of the mankind.This kind of situation seriously hinders further developing of mariculture industry, carrys out serious consequence to cultivation industrial belt.One of effective ways addressed these problems, reach the object of healthy aquaculture exactly by regulation and control nutrient additive.
Three, summary of the invention:
Object of the present invention is exactly to solve because modern intensiveization cultivates the problem that stress work the mischief to fish body with environment-stress brought, fish feed additive special providing a kind of resisting stress and preparation method thereof.
Because unrighted acid is mainly through affecting Steroidgenesis to affect anti-stress ability, thus adopt vitamin E as fat-soluble antioxidant, the oxygen radical participating in being brought by stress reaction in purged body stops lipid peroxide reaction, design a kind of grease additive containing vitamin E, vitamin E is mixed in proportion with fish oil EPA, fish oil DHA, linseed oil and soybean oil, spraying coating is on dry pellet, make it in water, have certain attractant, increase the utilization rate of mixed feed Middle nutrition element simultaneously, reach the effect of growth promotion, resisting stress.
The technical scheme that the present invention takes regulates and controls nutrient exactly as feedstuff additive for sea water fish, and it is made up of polyunsaturated fatty acid and vitamin E, and in the present invention, feed addictive comprises: fish oil EPA, fish oil DHA, linseed oil, soybean oil, vitamin E.Adopt the additive of nutrient composition thus, can be used as fish feed additive special, namely there is certain anti-stress effect, the utilization rate of nutrient can be improved again, and there is certain food calling effect.
The present invention is achieved through the following technical solutions:
A kind of fish feed additive special, its special feature is to be obtained by following raw material components, is respectively by the weight portion of each component: fish oil DHA 2-10 part, fish oil EPA5-15 part, linseed oil 45-55 part, soybean oil 30-38 part, vitamin e1-5 parts.
Wherein in fish oil DHA and fish oil EPA, the percentage by weight of total fatty acid content requires to be greater than 1, i.e. fish oil DHA/EPA requires to be greater than 1, long-chain n-3 and short chain n-3 total fatty acid content percentage≤50%, TFA weight ratio >=2 of n-3 and n-6.
Preferably, fish feed additive special adopts following raw material components to obtain, and is respectively by the weight portion of each component: fish oil DHA 7 parts, fish oil EPA9 part, linseed oil 46 parts, soybean oil 36 parts, vitamin E2 part.
The above fish oil DHA accounts for the refined fish oil of TFA percentage composition >=66% from commercially available DHA; Fish oil EPA accounts for the refined fish oil of TFA percentage composition >=48% from commercially available EPA.
Described vitamin E from commercially available Vitwas E, purity >=50%.
Described linseed oil and soybean oil all from commercially available, C18:3n-3 percentage composition >=54% in linseed oil, C18:2n-6 percentage composition >=52% in soybean oil.
The preparation method of above-mentioned fish feed additive special, comprises the following steps:
1) get the raw materials ready: take various raw material by the weight portion of each component;
2) mixed once: first fish oil EPA and fish oil DHA are carried out first time mixing, put into and have intelligent temperature control ultrasonic stirrer container, incorporation time is 90-120 second;
3) secondary mixing: added by vitamin E in the good material of mixed once, carry out secondary mixing, incorporation time is 100-150 second;
4) three mixing: linseed oil and soybean oil are added in material that secondary mixes, carry out three mixing, incorporation time is 120-240 second;
5) packing: by step 4) mix product packing mark, require 4-8 DEG C of preservation.Wherein step 2), step 3), step 4) in mixing time temperature all control at 4-8 DEG C.
The application process of the fish feed additive special prepared according to the method described above is:
Take this additive according to the ratio of the 5-20 ‰ of marine fish feed weight, additive is evenly mixed in oil tank, utilize on airless spraying technology coating to marine fish feed.
Such as with the addition of 1 ton of marine fish feed for benchmark, this fish feed additive special is 5-20kg at the addition of marine fish feed.
Advantage of the present invention:
1. the marine fish feed specialist additive adopting the inventive method to make is rich in EPA, DHA, leukotrienes, linoleic acid and vitamin E, the demand of the intensive high-density breeding of multiple fish can be met, the environmental stress making fish reduce environment and human factor to bring, improves the anti-stress effect of fish.
2. the resisting stress physiology of applied nutrition element regulation and control fish, safe and efficient, has no side effect.
3. in the present invention because adding appropriate high unsaturated fatty acid, there is certain food calling effect, add ingesting of fish, improve juvenile fish survival rate, add culture benefit.
