Abstract

The present invention relates to a manufacturing formula of feed with high protein (FS-high-protein feed), which is efficient ternary proteosome multipolymer referred as the feed with high protein, which is produced by using various vegetable protein sources as carriers and animal protein as core protein sources via microorganism fermentation, the feed with high protein is used for feeding domestic animals and marine products, and the animal protein sources come from bovine blood, sheep blood and chicken blood. After microorganism fermentation, semi-finished products have a balanced proportion of amino acid through artificial allocation, and the content of the protein of each semi-finished product is from 50 to 55 %. The feed contains no germicide, has no pollution in manufacturing process and has safe and effective process.

Description

Prescription for preparing high-protein feed

The present invention is the prescription of a kind of production by the ternary high protein feed of animal, plant, microprotein.

One, Fa Ming background

The discarded object of poultry blood (as ox, sheep, chicken blood) for butchering, not only contaminated environment also causes the person poultry disease after going bad easily.But poultry blood contains the dry of 10-15%, and its blood meal contains crude protein all more than 70%, is a kind of fabulous protein resource, protein inadequate resource in the world today.Present have the animal protein of 1/3 population to obtain quantity not sufficient 10 grams (average everyone 15 grams in the world) so develop effective protein proteins matter resource at a low price every day in the world, take in for improving the general protein level of people, and the reduction feed cost, significant.The ability that China produces mixed feed and mixed fodder nineteen ninety has reached 5,000 ten thousand tons, needs 1,500,000 tons of animals ' protein forages.Imported fish meal reached 600,000 tons in 90 years, can not satisfy the demand far away, and thisly be converted into irrational food chain structure, even like this, the demand of animals ' protein forage also also has big gap, cause the cross-infection of congenerous disease pathogenic microorganism easily with the fish meal fishes and shrimps of feeding in addition, this problem of the breed under the intensification condition will be more serious.

For addressing this problem, Japan scholar rattan Tian Xing controls Mr., adopt microbial strains, join with auxiliary material, the fermentation animal waste prepares protein feed (see a day disclosure special permission communique: clear and 51-145792,1976), is applied to aquaculture, obtain effect preferably, also had some fermented products in addition.But in use find, because its protein content is on the low side, the mixed feed that is used for breed such as marine product such as prawn and other high protein level uses, can reduce total prescription protein level, if only consider that improving protein level certainly will influence amino acid balance in the feed, and then reduce digestibility.At the problems referred to above, the present invention forms new prescription by technological improvement, promptly improves protein content, guarantees that again the absorptivity of animal does not reduce, and the novel protein feed is referred to as " high protein feed ".

Two, Fa Ming description

Fig. 1 is seen in the description of invention

At first with fresh poultry blood, 100-105 ℃ of boiling 10 minutes is after carrying out degerming and checking, think qualified can be as animal protein source, with various puffed soybean agricultural-products as plant protein source, after it is pulverized, mix with animal protein source, the preparation of the sort of quyi is carried out as follows:

At first saccharomycete is seeded in 500 milliliters of triangular flasks, cultivated about 24 hours for 30 ℃, be extended to again in 5000 milliliters of triangular flasks, be after the cultivation to enlarge and cultivate seed.

2, Aspergillus is seeded in 500 milliliters of triangular flasks, cultivated 24 hours for 28 ℃, go to again in the 5000ml triangular flask, be after the inoculated and cultured to enlarge and cultivate seed.

Above-mentioned seed is connect certain proportion to be mixed.Cultivated 24 hours, and add certain auxiliary material, cultivated about 24 hours, 28 ℃ are the sort of quyi.

The sort of quyi is mixed by a certain percentage with above-mentioned two kinds of protein sources, and to control its moisture content be 45-50%, can ferment after stirring evenly.

About fermentation to 30 hour, overturning once continues fermentation, to 70-90 hour, is fermentation ends.

With the feed that ferments, in 105 ℃, sterilization in 25 minutes, the threshing ground is cool then shines, when water content reaches 20% left and right sides.Dry about 110 ℃, 10 minutes, product moisture content about 10% was crushed to 40 orders, is finished product.

Embodiment 1, prescription (jin): blood product 2400; Soya-bean cake powder 700

Sesame residues 700; Wheat bran 200

The sort of quyi 10

Blood product and other plant albumen auxiliary material are mixed, after the sort of quyi is uniformly dispersed with auxiliary material, be seeded in the compound, stir evenly and add water to water content 50%, the cross stacking is built with Polypropylence Sheet and is preserved moisture in the dress bamboo basket, 28 ℃ of room temperature fermentations were to about 30 hours, and the overturning material is once adorned basket after fermentation to 70 hour end again.

Fermentation material steamed 30 minutes, 105 ℃; Platform shines cool, Tumblies Dry at last to total moisture content 20%, and being crushed to 40 orders is finished product, and product contains protein 53 %

Embodiment 2:

4500 jin of blood products; 3750 jin of rape cakes

25 jin of the sort of quyis

The rape cake of blood product and pulverizing is mixed, and the sort of quyi mixes up with auxiliary material and is seeded in the compound, stirs to add water to total amount 50%, 35 centimeters fermentations are piled up on dress basket or ground, and overturning is once fermented again to 80-90 hour between 30-40 hour, after the fermentation ends, to expect 105 ℃ of steamed 20 minutes, platform is cool to be shone, to moisture 20%, last drying machine drying, be crushed to 40 orders, be finished product, contain protein 52.5%

Embodiment 3: 1200 jin of blood products; 300 jin in soya-bean cake powder; 200 jin of rape cakes

200 jin of cottonseed cakes; 100 jin in rice bran; 6 jin of the sort of quyis

The vegetable protein material is pulverized the back mix with blood product, the sort of quyi is seeded in the compound after being uniformly dispersed with auxiliary material, stirs evenly, and adds water to total moisture content 50%, and dress basket or concrete floor tiling are put the back well and built with Polypropylence Sheet, preserve moisture.28 ℃ of room temperatures were fermented to 30-40 hour, overturning once, again dress basket or stir after fermentation to 75 hour about finish.

105 ℃ of steamed of fermentation material, 20 minutes; Cold is shone to water content 20% then, last drying machine drying.Being crushed to 40 orders is finished product, and product contains protein 53 .5%
