Abstract

The invention relates to a process for producing a bioprotein feed, which is characterized by comprising the following steps: selecting slant strain, dried blood, white sugar, bran and brewer's grains according to a certain weight ratio; mixing, stirring, inoculating, carrying out enzymolysis, breeding and drying to manufacture a strain material; and selecting the strain material, dried blood, meat powder, bean pulp, bran, sucrose and slant strain according to a certain weight ratio, mixing, stirring, carrying out secondary enzymolysis, and drying to obtain the finished feed. The strain material is firstly produced, thereby enhancing the biodegrability, promoting decomposition and facilitating even mixing. The product prepared by the process combines the advantages of biological enzymolysis and microbian glycolysis, enables the dried blood and the meat powder to have favorable degradation effect, has the advantages of high digestability, good palatability, balanced nutrition, convenient production, low investment, low production cost, and can be used for replacing 80% of fish meal.

Description

A kind of process for producing bioprotein feed

Technical field

The present invention relates to a kind of production method of feed, particularly a kind of process for producing bioprotein feed.

Background technology

Gross protein value reaches more than 80% in the leftover bits and pieces such as livestock and poultry blood meal, digested tankage, is used to substitute part fish meal, dregs of beans production biological protein feedstuff for a long time.Traditional production method is to adopt cooking process, but the product digestibility of production is low, palatability is poor, the amino acid content imbalance.In order to overcome the defective that conventional production methods exists, at present, generally adopt boiling to dehydrate method production both at home and abroad again, though the nutritive value of product is better than the conventional production methods, investment is big, high, the troublesome poeration of production cost.

Summary of the invention

The objective of the invention is in order to overcome above-mentioned weak point, a kind of investment is little, production cost is low and provide, and is easy to operate, but the process for producing bioprotein feed of the digestibility height of product, good palatability, nutrient balance.

For achieving the above object, the concrete production method of the present invention's employing is as follows:

1, planting material makes: choose slant strains 5%-10%, dried blood 50%-60%, white sugar 10%-20%, wheat bran 10%-20%, brewex's grains 5%-10% by weight, mix and stir, place under 32 ℃ of-50 ℃ of environment, after 36-62 hour inoculation, enzymolysis, expanding propagation, drying for standby.

2, finished product is made: choose kind of material 10%-30%, a dried blood 40%-60%, digested tankage 10%-30%, dregs of beans 10%-15%, wheat bran 5%-10%, sucrose 1%-2%, slant strains 1%-2% by weight, mix and stir, place under 32 ℃ of-50 ℃ of environment, through after 36-62 hour the secondary enzymolysis, dry, pack finished product feedstuff.

The present invention makes kind of a material earlier owing to adopt above process, can strengthen degradation capability, promotes to decompose, and is convenient to stir.In the preparation raw material, adopt special bacterial classification group, proteolysis power is strong, and can produce biological active material, promotes to decompose; Dried blood, finished product digested tankage have been eliminated pathogen through high-temperature process, and moisture is low simultaneously, and enzymatic conversion is success easily; Carrier adopts raw materials such as dregs of beans, wheat bran, with sucrose, kind material, bacterial classification, blood meal, digested tankage, can satisfy the nutritional need of microorganism, helps the propagation of microorganism and the generation of enzyme.Combine the two-fold advantage of biological enzymolysis and microorganism glycolysis, make blood meal, digested tankage play good degradation effect, utilize the enzyme of microorganism secretion that livestock and poultry blood meal, digested tankage are carried out enzymolysis, make the macromolecular weight protein that wherein is difficult to digest be degraded to small molecular weight protein, peptone, peptide class and a considerable amount of water-soluble amino acids, help absorbing, thereby reach the purpose that improves blood meal, digested tankage utilization rate.But the digestibility height of product, good palatability, nutrient balance, easy to make, invest little, production cost is low.The fish meal of product protein feed alternative 80% uses, through on probation, the feed that this production technology is produced substitutes the part fish meal in the mixed feeds such as fish shrimp crab of fresh water and seawater, color, smell and taste etc. are better, indexs such as physics and chemistry health are more reliable and more stable, and the digestibility of fish shrimp crab class improves 3%-6% under the equal conditions.

The specific embodiment

1, planting material makes: choose slant strains 8%, dried blood 55%, white sugar 15%, wheat bran 12%, brewex's grains 10% by weight, mix and stir, place under 32 ℃ of-50 ℃ of environment, after 36-62 hour inoculation, enzymolysis, expanding propagation, 35 ℃ of-60 ℃ of following drying for standby of thermophilic.

2, finished product is made: choose kind of a material 20%, dried blood 50%, digested tankage 10%, dregs of beans 10%, wheat bran 6%, sucrose 2%, slant strains 2% by weight, mix and stir, place under 32 ℃ of-50 ℃ of environment, through after 36-62 hour the secondary enzymolysis, 35 ℃-60 ℃ of thermophilics are dry down, pack finished product feedstuff.The powerful fermented bacterium that slant strains in the present embodiment adopts Zhuhai City bioengineering Co., Ltd of pearl section to produce, wheat bran can replace with rice bran, and white sugar can substitute with sweet close element.
