Abstract
The invention relates to a production method for high-absorption prawn fodder, which is characterized in that soybean meal, fish meal, flour, shrimp powder, wheat bran, multi-vitamin mineral and soybean phospholipid are adopted as the main materials which are crushed to ultrafine particles and are fully and evenly stirred; the active enzyme is dissolved in fish oil; and the solute is made into fodder through the post spraying method. The invention has the advantages that digestion and absorption of nutrient and utilization ratio of fodder are improved in the mode of adopting active enzyme, improving the micro-ecological environment of digestive tract and activating the relevant physiological factors, thus growth of aquaculture organisms is promoted; discharge of nitrogen and phosphorus is reduced; finally substitute for hormone and reduction of environmental pollution are realized.
Description
Affiliated technical field
The present invention relates to culture fishery, refer more particularly to a kind of production method of feed of cultured prawn.
Background technology
Along with the raising of living standards of the people and the growth that food nutrition is required, the prawn culturing area of China is significantly increasing, the shrimp culture industry development rapidly, but prawn feed production and scientific and technological research and development level far do not catch up with the development of aquaculture, especially the absorption rate of prawn feed is low, and unabsorbed protein content is too high in the excreta of shrimp body, causes the breeding water body ammonia nitrogen to increase, destroy breeding water body, and influenced the prawn growth.In order to improve the absorptivity of feed nutrition, indivedual producers adopt and add illegal drug, as hormone etc., have had a strong impact on the security to shrimp food.
Summary of the invention
The production method that the purpose of this invention is to provide a kind of high absorption prawn feed, it can improve the absorption rate of feed effectively, reduces the pollution to water body.
For achieving the above object, the present invention is achieved in that
A kind of production method of high absorption prawn feed, be to be primary raw material with dregs of beans, fish meal, flour, shrimp med, wheat bran, the many ore deposits of multidimensional, soybean lecithin, ultramicro grinding also stirs, again through preceding slaking, granulation, post curing operation, again active enzyme preparation is dissolved in the fish oil, and the gained dissolved matter adopted the method for back spraying, spray on the post curing gained feed grain and form.
The weight ratio of the above primary raw material is:
Dregs of beans: 200-300
Fish meal: 250-350
Flour: 200-250
Shrimp med: 80-120
Wheat bran: 100
The many ore deposits of multidimensional: 14
Soybean lecithin: 5
Active enzyme preparation: 0.5-1
Fish oil: 8-15
The concrete processing technology that is adopted is:
With dregs of beans, fish meal, flour, shrimp med, wheat bran, the many ore deposits of multidimensional, soybean lecithin is primary raw material, carry out just pulverizing through batching and after fully mixing, raw material pulverizing fineness requirement 70 mesh sieve percent of pass 80%, after enter operation:
A. ultramicro grinding: just pulverize mixed raw material and pass through ultramicro grinding once more, material fineness reaches 90 mesh sieves and divides percent of pass more than 90%.
B. preceding slaking: ultramicro grinding and abundant mixed raw material are entered in ager, use superheated steam to carry out slaking, 80 ℃ of temperature, and increase water content and reach 20%.
C. granulate: through the raw material of preceding slaking, adjust temperature and humidity after, extruder grain in granulator, by extruding, material temperature rises to 95 ℃, enters the post curing operation then.
D. post curing: after the compression of granulating, the temperature of particle is 95 ℃, enters the post curing device, uses steam insulation 20 minutes, improves the amount of cure of material, guarantees its digestibility.
E. spraying: active enzyme preparation is dissolved in the fish oil, is heated to 40 ℃ and is sprayed at the feed granules surface.
F. obtain finished product of the present invention after cooling off, packing.
The above fish oil can be with in soya-bean oil and the fish oil a kind of.
The invention has the beneficial effects as follows:
1. the present invention divides percent of pass more than 90% through feedstuff fineness 90 mesh sieves after the ultramicro grinding, has guaranteed that the nutrient in the feed is fully absorbed.
2. the present invention adopts the way of back spraying, has avoided the ultramicro grinding and the high-temperature maturing processing technology of prawn feed production process, has guaranteed the biologically active of enzyme preparation, thereby the protein in the feed can fully be absorbed by prawn.
3. the use active enzyme preparation improves modes such as alimentary canal micro-ecological environment, the relevant physiological factor of activation, improve nutrition digestion to absorb and efficiency of feed utilization, thus the growth of promotion aquaculture organism, the discharging of reduction nitrogen phosphorus, final realization substitute hormone, minimizing environmental pollution.
