Description

A kind of creamy taste hirudiniculture feed and preparation method thereof

Technical field

The present invention relates to Aquatic Feed Processing preparing technical field, be specifically related to a kind of creamy taste hirudiniculture feed and preparation method thereof.

Background technology

Leech, is commonly called as leech, and it is a kind of valuable Chinese medicine, Ancient Times in China much medical science ancient books and records are all on the books, record in Ming Dynasty's Compendium of Material Medica: the water frog " main by extravesated blood, trace blood, close by the moon, gather under broken blood; s.m.p, Li Shui leads to ... control injured pendant and flutter poultry blood and gain merit ".Modern medicine study shows, containing a kind of anticoagulant material in leech glandula---leech element, can be widely used in the medical field such as the replantation of a severed limb, inhibition cancer cell growth.Along with application and the raising of modern biotechnology, the extraction processing of leech element and clinical medicine application, and the exploitation of Chinese patent drug, development and popularization, the demand of leech is increased year by year, in addition the pollution of natural environment is caught with artificially excessively adopting, total resources reduces year by year, and price but constantly rises, and is badly in need of development leech and propagates artificially to make up under-supply.From the hirudiniculture technology grasped at present, present stage hirudiniculture, main using animal blood, earthworm and spiral shell, freshwater mussel etc. as edible feed, these feed manufacturing degree are not high, the absorption and use efficiency of nutriment is low, leech poor growth, and the culture-cycle is long, growing way is bad, also very easily causes the generation of the situation of dying of illness.Owing to lacking suitable feed, the Quality and yield of hirudiniculture all receives very large impact, therefore, is badly in need of developing the leech feed with high cultivation efficiency and high added value and comes out.

Summary of the invention

In order to make up the deficiencies in the prior art, the invention provides a kind of creamy taste hirudiniculture feed and preparation method thereof.

Technical scheme of the present invention is as follows:

A kind of creamy taste hirudiniculture feed, the weight portion of its constitutive material is: shrimp chaff 150-170, puer tea slag 10-20, fresh porcine blood 40-60, dregs of beans 70-80, pig marrow 30-40, Yoghourt 2-3, rice washing water 20-30, molasses 0.4-0.6, yeast extract 0.2-0.3, EM zymophyte 0.1-0.2, salt 0.3-0.5, rare cream 3-5, sucrose fatty ester 0.1-0.2, glucose syrup 0.4-0.6.

The preparation method of described creamy taste hirudiniculture feed, comprises the following steps:

(1) molasses, yeast extract are joined in rice washing water and mix, boiling sterilization 20-30 minute, take out, be cooled to room temperature, then add EM zymophyte and mix, 30-35 DEG C of insulation 18-36 hour, obtain activation bacterium liquid;

(2) shrimp chaff, puer tea slag, fresh porcine blood are mixed, then the activation bacterium liquid adding step (1) mixes, add water and regulate water content to 58-68%, sealing and fermenting 2-3 days, obtains first fermentation material;

(3) mixed with dregs of beans, pig marrow, salt by the first fermentation material of step (2), then add Yoghourt and mix, add water and regulate water content to 55-58%, sealing and fermenting 1-2 days, obtains secondary fermentation material;

(4) rare cream, sucrose fatty ester and other surplus stocks are joined in the secondary fermentation material of step (3) and mix, 50-70 DEG C of oven dry, is ground into 200-300 object powder with pulverizer, and pack sealing, namely obtains finished product.

Beneficial effect of the present invention:

1, the present invention adopts fermenting twice technique, first fermentation is with shrimp chaff, puer tea slag, fresh porcine blood cooperatively interacts, the pungent fishy smell of fresh porcine blood is eliminated while decomposition and inversion shrimp chaff, and make fermentation material fragrant with light tea, improve digestibility and the attractant of raw material, the first fermentation material of gained again with dregs of beans, pig marrow, secondary fermentation is carried out in salt cooperation, add micromolecule polypeptide, the content of fat, improve palatability and the anti-corrosive properties of fermentation material, last again with rare cream, sucrose fatty ester etc. with the use of, fermentation material is made to have the milk fragrance of food calling, add the food amount of leech, facilitate leech to grow, shorten the culture-cycle, improve the Quality and yield of hirudiniculture.

2, final products of the present invention are micronised state, easily dissolve or suspend in water, and the adsorbable feeding that carries out on sponge is fed, and easilier than general Large stone feed search for food and are easy to digestion, and feeder reservoir is easy, long shelf-life.

Detailed description of the invention

Below in conjunction with the embodiment of the present invention, be clearly and completely described the technical scheme in the present invention, every simple distortion that other are made when not departing from core of the present invention or amendment all fall into protection scope of the present invention.

A kind of creamy taste hirudiniculture feed, the weight portion (kilogram) of its constitutive material is: shrimp chaff 150, puer tea slag 10, fresh porcine blood 40, dregs of beans 70, pig marrow 30, Yoghourt 2, rice washing water 20, molasses 0.4, yeast extract 0.2, EM zymophyte 0.1, salt 0.3, rare cream 3, sucrose fatty ester 0.1, glucose syrup 0.4.
