A kind of preparation method of the pig feed containing cattle manure
Technical field
The present invention relates to field of feed, the preparation method of more particularly to a kind of pig feed containing cattle manure.
Background technology
In recent years, with the fast development of cattle-raising, cattle manure is processed also becomes the problem that people compare concern, according to relevant money
Material shows, in some places, pollution of the cattle manure to environment has exceeded the total amount of industrial pollution, even as high as more than 2 times for having,
More than 7 tons, the feces of a cattle generation are caused very between 5--6 tons the feces that one cow head is produced every year to environment
The orthobiosiss of nearby residents are had undesirable effect by big pollution, while cattle manure is various bacteria pathogen grows breeding again
Source, cultured population is had a serious impact, therefore how cattle manure just processes and utilized into focus of concern.
Research shows, contains more rich protein, crude fibre, also containing some mineral, vitamin and not in cattle manure
The trophic factors known, at present in the preparation of pig feed, pursue mostly and fatten, shorten fattening time, add various hormones, formula
Also it is unreasonable so that the pig diet structure of cultivation is unreasonable, has a strong impact on mouthfeel, in the modern society for pursuing quality and mouthfeel,
It is difficult to meet the demand of existing market, so, cow dung resource is developed, cattle manure is made pig feed has become a development mesh
Mark, can not only turn waste into wealth, energy saving, can also reduce production cost, obtain more profit, with good promotion price
Value.
The content of the invention
The present invention is solution above-mentioned technical problem, there is provided a kind of preparation method of the pig feed containing cattle manure.
Realize particular by technical scheme below:
A kind of preparation method of the pig feed containing cattle manure, it is characterised in that comprise the following steps:
(1) cattle manure pretreatment:Natural air drying is collected to water content in 55~60% cattle manure, concentrates the drying to water content to be
7~9%, 3 times of cattle manure gross mass of water is added, the disinfectant of cattle manure gross mass 10~15% is added, fluidized state 130 is kept
~150min, adds deodorizer, after stirring 15min, adds biological activated carbon, stir 3min, filter when being cooled to 50~60 DEG C.
(2) cattle manure precision processing:Filtering residue after step (1) is filtered, dries to water content 10~13%, obtains cattle manure and does
Powder, by the filtrate after filtration, is concentrated into the 1/3 of filtrate cumulative volume, adds 18~22h of alcohol steep, decompression recycling ethanol, then plus
Enter acetone, extract 8~12h, raffinate is brewed into paste, obtains cattle manure extractum by recovered under reduced pressure acetone.
(3) prepare feedstuff:By cattle manure extractum, cattle manure dry powder, nutrient, adjuvant by 1: 0.3~0.5: 1~1.3: 0.8~
1.3 mass ratio mixing, stirs evenly, and stir-fry in being put into the pot that pot temperature is 75~80 DEG C 20~25min, obtains grog, adds grog total

In sum, the beneficial effects of the present invention is:Cattle manure, nutrient, adjuvant are matched somebody with somebody by the present invention by scientific and reasonable
Than, improve feedstuff palatability, increase pig appetite, by being dehydrated to cattle manure, deodorization, sterilization, purification the step of so that in cattle manure
Nutritional labeling release is thorough, reduces hormone, the use of antibiotic in traditional pig feed, is effectively promoted the growth promoter of pig, subtracts
It is few sick, while turning waste into wealth for cattle manure can also be realized, meat nutrition and mouthfeel is improved, improve the economic benefit of animal cultivation.
By carrying out pretreatment to cattle manure, the pathogen in cattle manure of effectively having become extinct grows breeding situation, also passes through
The process of Chinese medicine, the microorganism deodorizer as made by proportion optimizing, stink that is safe and nontoxic, effectively eliminating cattle manure, it is ensured that
The palatability of feedstuff, afterwards by the precision processing to cattle manure, separately purifies to cattle manure, pretreated filtering residue and filtrate is entered
Row is processed, and by the extraction respectively of ethanol and acetone, is discharged the nutrient substance in cattle manure to greatest extent, preferably full
Demand in sufficient pig growth course to nutrition, no added any hormone, it is ensured that feedstuff it is safe and healthy, effectively raise
The meat of Carnis Sus domestica and mouthfeel.
Add adjuvant in feedstuff, wherein comprising antioxidant, feed vector, facilitating digestion material, effectively keep away
Exempt from going mouldy for feedstuff, it is ensured that the durability of feedstuff, meanwhile, by the effect of carrier, the absorption with pig being more beneficial for, raising disappears
Change ability.
