Description
Technical field
The present invention relates to feed industry and livestock breeding industry field, be specifically related to a kind of preparation method utilizing orange peel to produce feeding micro-ecological preparation.
Background technology
Since 20 middle of century find that antibiotic to make an addition to sub-therapeutic dose and have growth-promoting effect in feed, antibiotic has been widely used in husbandry sector, brings certain economic benefit to animal husbandry.At present, no matter be the prevention of livestock and poultry or the treatment of livestock and poultry, still substantially antibiotic is used.But use antibiotic in a large number for a long time, under making pathogenic microorganism produce drug resistance, livestock products drug residue and livestock and poultry body autoimmunity, degradation problem becomes increasingly conspicuous, cause that the generation of livestock and poultry is increased, mortality of livestock and mortality rise year by year, bring huge economic loss to livestock breeding industry.Antibiotic etc also has potential harmfulness to human health by the accumulation of food chain simultaneously.Therefore, measures such as forbidding or limit the use of is taked to antibiotic use in countries in the world, also impels people to find antibiotic substitute as feed addictive simultaneously.
Probiotics is considered to antibiotic effective substitute.Probiotics be use beneficial microbe through fermentation special process of etc.ing make contain viable bacteria and (or) extremely bacterium, comprise the viable bacteria goods of its component and product, have nontoxic, have no side effect, the advantage such as noresidue, and normal flora balance in enteron aisle can be maintained, improve the balance of mucomembranous surface place microorganism or enzyme, improve organism metabolism and strengthen the effects such as immunity of organism.At present, also there is certain problem in commercially available liquid state or solid-state probiotics, and as commercially available liquid probiotics, its production equipment requires that high, energy consumption is large, and the waste water of discharge can contaminated environment; The primary raw material of commercially available solid-state probiotics is the feeding raw material such as dregs of beans, wheat bran, produces probiotics will tie up feedstuff in short supply if be used for, and is difficult to reduce aquaculture cost.Therefore, under the background of built environment friendly, conservation-minded society, develop eco-agriculture and become a kind of trend, particularly under feed resource shortage and the pressure that is growing more intense of industry competition, waste residue is made the feature of environmental protection, low cost feeding micro-ecological preparation significant.
At present, along with the development of Citrus procession industry, there is a large amount of orange peels, only Hunan Province produces orange peel about 200,000 tons per year.Orange peel has nutritive value and medical value, containing nutritional labelings such as abundant carbohydrate, fat, vitamin, amino acid and mineral matters, but the orange peel water content of undried is very high, easily rot, be not suitable for long-distance transport and long-term preservation, that abandons easily causes the waste of resource and the pollution to environment.At present, the orange peel of most domestic is landfilled to abandon and slatterns, only have sub-fraction to be dried and become animal feed as Chinese herbal medicine or ensiling, make animal feed also because of its heavy bitter taste, palatability is poor, protein content is not high, animal absorbs bad and be difficult to industrialization, so imperative to the utilization of orange peel, research, innovation.
Domestic and international for the application of orange peel in herding and research at present: a main approach is exactly that orange peel is processed into feed.The Citrus procession big countries such as annual Brazil, the U.S. are making pellet after the orange peel drying of more than 40%; Add duck feed with the citrus peel meal of 1% ~ 2% according to the study, 2% ~ 3% adds chicken feed, and 5% ~ 10% adds pig feed and adds in ox feed with 10% ~ 20% and feeds, and all obtains good effect.Such as orange peel mixes in pig feed and feeds pigs, more than general pig 50 ~ 100 grams of daily gain.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and can produce the preparation method of feeding micro-ecological preparation and the feeding micro-ecological preparation of application beneficial microbe many bacterium solid state fermentation orange peel production by efficiency utilization orange peel.This feeding micro-ecological preparation can improve the feed intake of livestock and poultry, improves feed efficiency, growth promoting effects; Immunity moderation function, strengthens resistance against diseases; Substitute feeding antibiotic, reduce diarrhea rate; Reduce nitrogen phosphorus emission in excrement, reduce excreta to the pollution of environment, reducing feed cost and aquaculture cost, is a kind of livestock and poultry high-efficiency and environment-friendly feed additive.
For achieving the above object, the invention provides a kind of preparation method utilizing orange peel to produce feeding micro-ecological preparation, it comprises the following steps:
1) seed liquor is prepared: be the Lactobacillus delbrueckii of CCTCCM207096 by preserving number, preserving number is the Bacillus subtillis of CCTCCM207097, Saccharomyces paradoxus that preserving number is CCTCCM207098 is seeded in MRS fluid nutrient medium, meat soup fluid nutrient medium, potato dextrose broth respectively, cultivate 18 ~ 24 hours at 30 DEG C ~ 37 DEG C;
2) fermentation solid medium is prepared: by weight by air-dry rear orange peel 100 parts, brewex's grains 10 ~ 15 parts, wheat bran 15-20 part, glucose 3 ~ 5 parts, dregs of beans 8 ~ 10 parts, 2 ~ 3 parts, urea, 2 ~ 3 parts, ammonium sulfate, potassium dihydrogen phosphate 0.2 ~ 0.5 part, 0.3 ~ 0.4 part, magnesium sulfate, pulverize respectively, mix after crossing 40 mesh sieves, add distilled water 100 ~ 120 parts, high-temperature sterilization 15-30 minute at fully mixing latter 121 DEG C thoroughly, is cooled to room temperature for subsequent use;
3) solid state fermentation: by step 1) prepare Lactobacillus delbrueckii, Bacillus subtillis, Saccharomyces paradoxus seed liquor 1 ~ 2:1 by volume ~ 2:1 ~ 2 mix, mixed bacteria liquid is joined step 2 in 5-10%V/W ratio) in the solid medium prepared, 30 ~ 40 DEG C of bottom fermentations 36 ~ 48 hours, obtained tunning;
4) tunning is carried out 50 ~ 55 DEG C of low temperature dryings, pulverize, obtain feeding micro-ecological preparation.
The feeding micro-ecological preparation utilizing above-mentioned preparation method to obtain is golden yellow powdery, water content≤10%, and its useful total viable count is respectively: bacillus>=1 × 10
8cFU/g, Bacillus acidi lactici>=1 × 10
8cFU/g, saccharomycete>=2 × 10
8cFU/g.
The beneficial bacterium fermentation of orange peel through filtering out is made feeding micro-ecological preparation by the present invention, be added directly in animal feeding-stuff, the double utility of orange peel and beneficial bacterium can be played, increase beneficial microorganism quantity in animal intestinal, the mineral element that some is necessary is provided, improve the conversion ratio of feed, prevent disease from occurring, and can economic benefit be increased.Microbiological treatment orange peel is utilized to be develop eco-agriculture, the sustainable development path of reasonable employment waste resource, available protecting environment.Yet there are no the report that many bacterium solid state fermentation orange peel produces feeding micro-ecological preparation aspect up to now.
The invention has the advantages that:
1, the present invention has hewed out the scientific and reasonable regeneration approach of orange peel, thus solve its pollution problem to environment, there is provided possibility for Citrus procession industry realizes zero-emission, not only also can create economic benefit for enterprise has saved pollution treatment expense, meet the strategy of sustainable development.
2, the present invention adopts many bacterium solid-state fermentation process to produce feeding micro-ecological preparation, and easy to process, energy consumption is low, produces and throws than high, and whole the process not only easy to control but also sorrow of no waste discharge, can realize cleaner production.
3, the raw material of the present invention more than 75% is orange peel and other slag class materials, and its abundance, cheap, production cost is low, can improve the competitiveness of enterprise.
