Description

A kind of Eriocheir sinensis promotees shell feed and preparation method thereof
Technical field
The invention belongs to animal feed production technical fields more particularly to a kind of Eriocheir sinensis to promote shelling feed and its system Preparation Method.
Background technique
Eriocheir sinensis (Eriocheir sinensis), it is commonly called as river crab, is under the jurisdiction of Arthropoda (Arthropoda), Crustachia (Crustacea), Eriocheir (Eriocheir).Its fine and tender taste, delicious flavour, are considered as Aquatic products treasure, the deep favor by the majority of consumers.The artificial breeding of Eriocheir sinensis is explored since the 70's of 20th century, it is existing Modern Eriocheir sinensis has become that China's fresh water new, special products of famous brands, of extra fine quality is leading and pillar kind, and freshwater aquiculture production in China's is being pushed to hold It plays an important role in continuous sound development.
Different from fish, growth is significantly realized by continuous shell for river crab growth pattern.Often occur in breeding production because Shell is unsuccessful and the problem of lead to river crab mortality, which is the bottleneck problem for restricting crab farming and more preferably developing.It sloughs off Shell is the critical stage of river crab growth and development, is also rarely reported for the feed of the particular biological behavior, relevant preparation side Method also has not been reported.Thus it is current be badly in need of developing it is a kind of for river crab shelling phase organism physiology demand, nutrition comprehensively, beneficial to river crab The rush river crab shelling nutrient enrichment fodder smoothly to shell and corresponding preparation method.
Summary of the invention
To overcome the shortcomings of that it is comprehensive, scientifical for river crab shell phase psychological need that above-mentioned river crab shell phase feed fails, originally Invention be intended to develop it is a kind of specifically for river crab shell psychological need, component compatibility it is scientific comprehensive, it is rich in natural constituents, The environment-friendly type river crab that stability is strong in water body promotees shell feed and preparation method.Now take following technical scheme:
A kind of Eriocheir sinensis rush shell feed, it is characterised in that:It is yellow including 2-4 parts of Radix Glycyrrhizae, 2-5 parts of Lysimachia sikokiana, fragrant 2-4 parts of pine 1-3 parts smart, 2-5 parts of Rhizoma Chuanxiong, 1-6 parts of Rehmannia glutinosa, 2-7 parts of Radix Astragali, 15-20 parts of fish meal, 7-12 parts of fly maggot powder, 9-13 parts of blood meal, 5-11 parts of corn flour, 5-8 parts of wheat flour, 8-12 parts of shrimp shell meal, 2-5 parts of tapioca, 1-4 parts of cottonseed oil, 1-2 parts of salt, tea 0.5-1 parts of polyphenol, 1-6 parts of bacillus powder, 2-5 parts of Bifidobacterium powder, 4-7 parts of multi-vitamins.
A kind of Eriocheir sinensis of the present invention promotees shell feed, and multi-vitamins mixture therein includes vitamin C, vitamin E, vitamine D3, vitamin B1 etc. is one or more.
A kind of Eriocheir sinensis of the present invention promotees shell feed, and preparation method comprises the technical steps that:
A. by Radix Glycyrrhizae, Lysimachia sikokiana, fragrant pine, rhizoma polygonati, Rhizoma Chuanxiong, Rehmannia glutinosa, Radix Astragali cleaning remove impurity.Then impregnated 50-60 Minute, it is then cooked by slow fire 1-1.5 hours, with 50-60 mesh net filtration, removes filter residue, retain filtrate;
B. fish meal, fly maggot powder, blood meal, corn flour, wheat flour, shrimp shell meal, tapioca, tea polyphenols are uniformly mixed, carry out one Secondary crushing makes it through 30 mesh screens, then pulverizes to first time mixture, makes it 90% by 80 meshes;
C. the separating twice object obtained in step B is sufficiently mixed, the filtrate obtained in step A is added, be uniformly mixed. Cottonseed oil is added, is uniformly mixed.
D. the mixture progress in step C is quenched, obtain quenched material;
E. the quenched material obtained in step D is subjected to expanded molding, then pelletized;
F. by bacillus powder, Bifidobacterium powder, multi-vitamins after mixing, are added cottonseed oil, are sprayed into obtained On feed granules;
G. the pellet of above-mentioned acquisition dried, cooled down, that is, obtain a kind of Eriocheir sinensis rush shell feed.
In step D, the refining temperature is 95-105 DEG C to the present invention, and conditioning period is 50-80 seconds.
For the present invention in step E, the swelling temperature is 100-110 DEG C, and puffing time is 30-50 seconds.
For the present invention in step G, each drying forage volume is 80kg, 30 minutes dry, final feed at 55 DEG C Water content controls below 12%.Finally the pellet cooling after drying is packed.
The device have the advantages that as follows:
Group used in the present invention is divided into natural constituents, has used a large amount of herbal component, effectively coordinating intestines and stomach can promote digestion, increase Strong immunity, food calling, resisting stress, supplement calcium phosphorus etc., further preferably joined the mould proof good natural fungicidal agent of function effect, guarantee Feed quality.It protects nutrient not to be destroyed to greatest extent in technique simultaneously while each component effect effectively plays, be a kind of It is ingesting conducive to river crab, the preferable river crab of stability promotees the dedicated heavy property expanded pellet diet of shell in water body.
