Description

The breeding feed of phase between cray shelling
Technical field
The invention belongs to field of feed, and in particular to the breeding feed of phase between a kind of shelling of cray.
Background technology
Cray is also referred to as Procambius clarkii, red crayfish and freshwater crayfish.Be similar to shrimp and crust is hard.Adult is about 5.6 ~11.9 centimetres, kermesinus, the nearly black in crust part, belly back side has a wedge-shaped striped.Juvenile prawn body is uniform grey, sometimes Has black ripple.Chela is long and narrow.Do not separated by areola in the middle part of crust, obviously has particle on crust.Volume sword has gemmule or volume Sword end has indentation.Cray is economic freshwater shrimps, because meat flavour is delicious wide welcomed by the people.Because of its omnivorousness, the speed of growth Soon, adaptable and absolute competitive advantage is formed in local environment.Its range of ingesting includes water plant, algae, water Raw insect, spoil etc., food are also killed each other when deficient scarce.
Scientific research proves that it is positive that content astaxanthin resists the ability of extraneous adverse circumstances with it in cray body It closes, also just says that body content astaxanthin is higher, the ability for resisting extraneous adverse circumstances is stronger.Purplish red color cray flesh The content of natural astaxanthin is the several times of prawn in body.So wine-colored cray can survive in dirty mud it is numerous It grows, and is not easy to survive in clear water body.Because cray itself can not generate astaxanthin, mainly pass through food chain --- Edible microalgae etc. gets astaxanthin, and constantly accumulation generates superpower oxidation resistance in vivo.Astaxanthin can effectively enhance The ability and raising fertility of the resistance adverse circumstances of cray.Therefore, astaxanthin is the so indomitable vitality of cray Strong guarantee, when instead cray is difficult to survive in lacking the environment that these contain astaxanthin microalgae.
The growth of cray is realized by shell.Shell is the important symbol of cray growth.Cray and its His crustacean is the same, it is necessary to which the growth of its mutability could be completed by sloughing off the crust of body surface.According to the activity of cray and ingest Situation, moulting cycle can be divided into intermolt, proecdysis, ecdysis and postmolt four-stage.The phase is small between shelling Lobster is the stage of growth accumulation nutriment, and the shrimp ingests vigorous in this stage, and crust is gradually hardened;Shell early period is from small Lobster stops having ingested to beginning shell and stop, this stage is that cray is prepared for shell.Cray stops ingesting, in crust Calcium shifted to calcium stone, internal calcium stone becomes larger, and crust is thinning, softens, and with inner cortex layer separation.The shell phase is from cray Shell of lying on one's side starts until crust is sloughed off completely, this phase duration about a few minutes to more than ten minutes etc., Wo Menguan What is observed is most at 5-10 minutes, and then cray is easily dead for overlong time.The shell later stage is taken the photograph to after cray shell Food stops, this stage is the process that the crust of cray is developed from cortical layer to crust.Moisture enters internal, body increasing from cortex Weight increases;The calcium of calcium stone is shifted to cortical layer, and cortical layer is hardened, thickens, and becomes crust, internal calcium stone finally becomes very little.
Invention content
To solve the above-mentioned problems of the prior art, the present invention proposes the breeding feed of phase between cray shelling a kind of, The feed can improve shelling during cray immunity, shorten shelling the time, substantially reduce the shell phase cray death rate.
The technical proposal of the invention is realized in this way:
The breeding feed of phase between a kind of shelling of cray, according to the number of parts by weight, including following raw material:
45~55 parts of corn flour, 5~10 parts of shrimp shell meal, 20~30 parts of fish meal, 10~20 parts of dregs of beans, peanut meal 10~20 Part, 15~25 parts of rape cake, 1~3 part of pumpkin powder, 5~10 parts of zeolite powder, micro- 0.2~0.8 part and feed addictive 3 ~6 parts;Wherein, the feed addictive includes with Rhizoma Atractylodis Macrocephalae, Radix Astragali, Radix Salviae Miltiorrhizae, Radix Glycyrrhizae, purple perilla, earthworm, spiral shell and fish scale raw material It is obtained through everfermentation.
Preferably, the preparation method of the feed addictive includes the following steps:
1) according to the number of parts by weight, weigh 15~25 parts of Rhizoma Atractylodis Macrocephalae, 15~25 parts of Radix Astragali, 10~20 parts of Radix Salviae Miltiorrhizae, Radix Glycyrrhizae 5~ 8~16 parts of 10 parts, 8~16 parts of purple perilla, 10~20 parts of earthworm, 8~16 parts of spiral shell and fish scale are mixed and are crushed to Powdered to obtain powder mixture, the water that 25~35 times of weight are then added boil that filtrate and filter residue is obtained by filtration;
2) it is put into beater after mixing filter residue with filtrate and carries out mashing processing, obtains slurries;
3) dry ferment after activation is added in the slurries of step 2) and is fermented, zymotic fluid is carried out at inactive yeast Then reason sequentially adds extraction from yeast enzyme and neutral proteinase in zymotic fluid, adjust pH to 4~7, while being warming up to 60~90 DEG C, for a period of time, then heat up enzyme digestion reaction enzyme deactivation, then is centrifugally separating to obtain supernatant, after supernatant concentration is dried.
Preferably, the addition of the dry ferment is the 3~6% of slurry weight, the extraction from yeast enzyme and the neutrality The addition of protease is the 1~3% of zymotic fluid weight.
Preferably, the trace element is one or more in manganese, silicon, boron, zinc, iron or magnesium.
Including following raw material preferably, according to the number of parts by weight,:
