Technical field

The present invention relates to the production technology of a kind of aquaculture, particularly relate to a kind of technology of utilizing earthworm to handle the high-quality forage protein of low-quality protein production with forage protein.

Background technology

Along with the development of aquaculture, increasing to the demand of protein raw materials, China is the country of protein raw materials scarcity, and raw materials such as fish meal, dregs of beans largely are to rely on import.And more rich low-quality protein raw materials such as feather meal, leather powder, peanut (cake) dregs of rice, cotton (cake) dregs of rice, dish dregs of rice etc., though have certain nutrient value, but, cause animal low to these protein raw materials absorption rates because of the improper or contained albumen of its amino acid contained ratio is difficult for being digested and assimilated by animal or containing higher factors such as ANFs.Though these protein raw materials output are very high in China, utilize lower.Peanut (cake) dregs of rice crude protein content is more than 45%, but it is bad that amino acid is formed, lysine content has only about half of soybean cake dregs, methionine content is also lower, and arginine content is up to 5.2%, be the highest in all animal and plant feeds, influence its application in animal feed because of its arginine content height, lysine content are low.Cotton (cake) dregs of rice crude protein is more than 38%, but it is undesirable that amino acid is formed, arginine content is up to 3.6-3.85%, and lysine content only has 1.3%-1.5%, and methionine is also not enough, about 0.4%, simultaneously, the utilization rate of lysine is relatively poor, and contains more gossypol, thereby has limited its adding proportion in feed.The amino acid ratio of the dish dregs of rice is not suitable for the needs of growth of animal, and contains harmful substances such as tannin, thioglucoside, saponin, has limited its adding proportion in the animal daily ration.It is many that animal proteins such as feather meal, leather powder contain keratin, and cystine height in the keratin, this kind albumen are difficult for being digested and assimilated by animal.Still do not utilize earthworm to handle the research report that the low-quality protein raw materials is produced high-quality forage protein up to now.

Summary of the invention

The purpose of this invention is to provide the earthworm that utilizes that a kind of production technology is simple, absorption rate is high, short growth of animals or poultry is effective and handle the technology of the high-quality forage protein of low-quality protein production.

The technical scheme that realizes the foregoing invention purpose is: the high-quality forage protein of final products of the present invention is made of the reactant of low-quality animal/vegetable protein and earthworm, and its production technology is undertaken by following step:

A, with low-quality protein raw materials screening, mix, carry out ultramicro grinding then, grinding particle size is at the 80-100 order, fine powder is standby;

B, earthworm screening, making beating: with bright earthworm screening, remove impurity such as wormcast, earth, add water then to pull an oar, the ratio of bright earthworm and water is 5～9: 1, and the making beating temperature is controlled at 20-25 ℃, and making beating liquid filters filtrate for later use with 20 mesh sieves;

C, with low-quality protein raw materials fine powder, earthworm filtrate and water in 1～2: 1: 1 ratio is mixed, and is 30～50 ℃ in temperature, reacts under the condition of pH value 5～7.5 8～12 hours, per hour stirs once between the stage of reaction;

After d, reaction are finished the reactant taking-up is carried out flash baking under 80～120 ℃ of temperature, moisture is controlled at below 12%;

Pulverize after e, the oven dry, grinding particle size is 20～60 orders;

Product after f, the pulverizing is a finished product, with finished product pack packing.

The ratio of each seed amino acid and lysine and livestock and poultry ideal protein pattern more more approach the ideal protein pattern in the reactant of the present invention; The medium and small peptide content of reactant reaches 5-25%, and the content of phytate phosphorus is lower than 0.1%.But be used for protein raw materials such as livestock and poultry breeding industry import substitution fish meal, high-quality dregs of beans, animal is had tangible growth promotion effect.And contain the antibacterial peptide of some in the reactant, and livestock and poultry is had certain prevention effect, can improve the livestock and poultry Abwehrkraft des Koepers.Technological process of the present invention in addition is simple, and cost of material is low, is fit to large-scale production.

The specific embodiment

The present invention will be further described below in conjunction with embodiment.

The present invention is a raw material with earthworm and animals and plants low-quality protein raw materials, comes the high-quality forage protein of processing.Invention thought of the present invention is, the earthworm body contains the albumen autolytic enzyme, and this enzyme can resolve into hmw protein low molecular weight protein and amino acid, improves lysine content in the reactant, improve the amino acid ratio, can eliminate the anti-oxidant action of some ANFs simultaneously.Finally reach the low-quality protein raw materials is changed into digestibility height, utilization rate height, has the purpose of the high-quality forage protein of disease-resistant growth-promoting effect.
