Abstract
The invention belongs to the preparation method of feed in the animal husbandry.
The natural fish meal that preparing animal fodder uses owing to each national residing geographical position difference, influences the source of natural fish meal resource.It is raw material that this present invention is adopted with hair or pig hair, is hydrolyzed with 10N hydrochloric acid, makes hydrolysising mother liquid, and it presses the mixed synthetic fish meal that gets of different proportion amount with soya-bean cake, blood meal, lysine, methionine and feather meal etc. again.The alternative natural fish meal of this synthetic fish meal, and feeding effect is good, and cost reduces, and is a kind of desirable feedstuff.
Description
The invention belongs to the preparation method of livestock feed.
Along with the development of animal nutrition science, when formula feed, add nutritions such as a certain amount of amino acid, vitamin and mineral matter and be widely used in feedstuff industry.The natural fish meal of animal protein multiselect of supply in formula feed, yet, be used as the fish meal resource of feed, different according to residing geographical position, various countries and environment, resource also is affected, in order to satisfy the requirement of feed industrial development, develop out a kind of synthetic fish meal that meets natural fish meal substantially.
The synthetic fish meal characteristics are to be raw material with originate widely hair or pig hair, through hydrolysis, neutralization, technology such as concentrate, make concentrated hair hydrolysis liquid.It mixes in different ratios with wheat bran, blood meal, high protein powder, meat meal tankage, lysine, methionine, stone flour, calcium monohydrogen phosphate etc. again makes.This pulverous synthetic fish meal of dark-brown that is has amino acid whose fragrance.Contained crude protein quantity equates substantially that with the content of the natural fish meal of Peru digestible energy is about 3000Kcal/kg.
The preparation technology of synthetic fish meal was divided into for two steps.The first step is the preparation of hair hydrolysis liquid; Second step was the preparation of synthetic fish meal.
The preparation of hair hydrolysis liquid be with hair or pig hair after purifying, put into hydrolytic decomposition pot, add 10N hydrochloric acid and be hydrolyzed, its weight ratio is 1: 1.6～1.8, hydrolysis temperature is 105 ℃～108 ℃, the time is about 9.5 hours.If hydrolysis temperature is greater than the cystine racemization that produces in 110 ℃ of gained hydrolyzates, less than 105 ℃, hydrolysis is incomplete as if hydrolysis temperature.Gained solution (hydrolyzate) neutralizes with ammoniacal liquor after the hydrolysis, and its pH value keeps 4.5～5.0 to be advisable.Solution after the neutralization has the partly precipitated deposits yields, is the crude product (byproduct) of cystine, after above-mentioned solution is filtered, gets filtrate and carries out vacuum and concentrate.Thickening temperature is 100 ℃～110 ℃, vacuum 500mmHg post, and the density of gained concentrate is 1.20g/cm
3, Baume degrees is 24.After concentrating the partially crystallizable deposits yields is arranged, be in ammonium chloride (byproduct).
Get above-mentioned mother liquor and mix with bone meal, blood meal, high protein powder, calcium monohydrogen phosphate, methionine, lysine, compound amino acid and stone flour, its percentage by weight is followed successively by 30.1%, 11.5%, and 28%, 1%, 1%, 1.5%, 25% and 2%.The component and the content of gained concentrated mother liquor are as follows in synthetic fish meal is produced:
The main content of gained synthetic fish meal:
Crude protein: 60%
Crude fat: 3.13%
Crude fibre: 1.36%
Calcium: 3.06%
Total phosphorus: 1.4%
Ash content: 14.21%
Methionine: 1.43%
Lysine: 3.81%
Methionine+cystine: 2.01%
Tryptophan: 0.33%
Threonine: 1.77%
Salt: 4%
Metabolizable energy: 2207Kcal/kg
The present invention and natural fish meal main component relatively are listed as follows:
The comparison of synthetic fish meal of the present invention and natural fish meal main component:
| The title classification | Synthetic fish meal (CFM) (%) | Homemade one-level fish meal (%) | The natural fish meal of Peru (%) |
| Crude protein methionine cystine lysine threonine tryptophan valine leucine isoleucine histidine digestible energy easily absorbs AA% | 60 1.43 0.60 3.18 1.77 0.33 2.42 3.43 1.40 1.02 | 52.9 1.40 0.57 4.59 2.60 0.80 2.27 3.45 2.17 0.77 | 62.8 1.67 0.65 3.29 1.98 0.70 3.05 4.53 2.50 1.54 |
By the table in more as can be known, crude protein and necessary amino acid whose content are near the natural fish meal of Peru in the synthetic fish meal, and itself have the amino acid fragrance that animal is liked, good palatability, particularly the free aminoacid content that animal can directly absorb in synthetic fish meal accounts for 80% of total amino acid content.Below surpass natural fish meal greatly, thereby be easy to absorb after making animal edible, be matched with the nutrient source application level that further improves feed in the feed.
Now exemplify and adopt synthetic fish meal feed prepared of the present invention, the result of the test of feeding chicken fowl is reported as follows:
Meat commercialization AA chicken is fed account (0-8 age in week)
Synthetic fish meal of the present invention can be beautiful with natural fish meal ratio, and the preparation method is easy, and is with low cost. During formula feed, addition is few, and successful is desirable nutrient source.
Claims (2)
1, a kind of synthetic fish meal that makes an addition in the animal feed is characterized in that with hair or pig hair be raw material, after Cystine is extracted in hydrolysis, concentrates and makes the condensed water hydrolysis mother liquor, again with high protein powder, blood meal, wheat
, lysine, methionine, calcium monohydrogen phosphate and meat meal tankage etc. mix.
2, according to claim 1, it is characterized in that the condensed water hydrolysis mother liquor is after being purified by hair or pig hair, with the reaction that is hydrolyzed of 10N hydrochloric acid.Its weight ratio is 1: 1.6～1.8; 105 ℃～108 ℃ of hydrolysis temperatures; Time is 9.5 hours.Solution neutralizes with ammoniacal liquor after the hydrolysis.Its pH value is 4.5, filters, and filtrate is carried out vacuum and concentrated.
