Description
Affiliated technical field
Patent of the present invention relates to the preparation method of probiotics, especially a kind of novel fowl preparation method of probiotics.
Background technology
The poultry cultivation of China has passed through the sustainable development of many decades, and the number of animals raised constantly increases, and quantum of output is also in continuous rising.2011, the poultry total output surpassed 1,600 ten thousand tons, and 2,811 ten thousand tons of birds, beasts and eggs total outputs increase by 1.8% than the last year.But even if China is the second-biggest-in-the-world production of poultry meat state that is only second to the U.S., and birds, beasts and eggs output accounts for more than 40% of Gross World Product, and the poultry cultivation level of China but still is in a kind of relatively original state.Our poultry consumption proportion is lower, and chicken consumption per head in 2011 only is 12kg, well below the 42.2kg of the U.S., the 40.6kg of Saudi Arabia and the 39.3kg of Brazil; Simultaneously, our poultry export volume is well below our poultry import volume.In recent ten years, our poultry outlet European Union has all suffered to besiege and chase, and European Union uses a series of TBT (Technical Barriers to Trade) to be means, raises poultry product import threshold, and the poultry that limits us enters EU market.In on May 24, August 1 to calendar year 2001 in 1996, contain animal epidemic and agricultural chemicals, residue of veterinary drug etc. in the poultry of European Union with Chinese exports and serve as reasons China is closed market.In January, 2002, European Union does not reach its requirement and serves as reasons to contain residual chloromycetin and Chinese trace standard of pesticide system from the Some Animals derived food of Chinese import, completely forbids from the animal derived product of Chinese import.Just at same year, " block and make " assigned to Chinese poultry product in succession by Korea S, Japan, Malaysia and Russia.Although again successively to the open poultry of Chinese Enterprise market, for the animal epidemic in our poultry, the problems such as agricultural chemicals, residue of veterinary drug needed us more to pay attention to since 2008 in these countries.
The paces of bird large-scale cultivation are constantly moving ahead, and the purpose of large-scale cultivation is to promote whole cultivation level, and are lower with green, science, efficiently cultivation means solution bird production performance, the problems such as agricultural chemicals, residue of veterinary drug.About the residue of veterinary drug problem, it all is the abuse that comes from feeding antibiotic that larger proportion is arranged.The poultry of China, egg production amount are huge, but most of product is for a long time all produced by small-sized raiser and provided.Large-scale cultivation degree in recent years improves gradually, just changes the small-scale raiser of professional large-scale farming field and sideline production and the situation of depositing into.Under this situation, cultivate very highly to the degree of dependence of manpower management and nursing, the level of raising is limited, and sanitary condition is not fully up to expectations especially, thereby the chance of blindly medication increases.Especially owing to cultivating improving constantly of intensive degree, stocking density is increasing, add that the modern varieties breeding technique excessively develops Production of Livestock and Poultry potential, cause the raiser in of short duration increasing economic efficiency, also to increase the various incidences that stress reach epidemic disease.These reasons cause the raiser to use more and more at the breeding process Chinese traditional medicine, progressively reach the degree that can't leave medicine in whole breeding process fully.
The risk problem of antibiotic resistance also still exists in the large-scale cultivation field, and at the beginning of this year, the Dutch consumers' association communique of releasing news says, on the Dutch market from 99% all having the antibiotic resistance risk in the chicken of intensive poultry farms.And the also comparatively serious antibiotics resistance problem of ubiquity of the various plants of China, pathogen isolated from clinical specimens has the trend that increases year by year to the resistant rate of the antibacterials such as tetracycline, kanamycins, streptomysin, gentamicin, Enrofloxacin, ampicillin.(2004), its equalitys of Zhao (2003) such as Zhang Zhengqing etc. (2007), Liu Shuanjiang are studied the drug resistance of fowl source salmonella drug resistance, chicken source Drug Resistance of E. coli, chicken coccidia medicine respectively.Result's demonstration, these three kinds of common germs have higher drug resistance to the above-mentioned antibacterials of enumerating.
2008, one piece of article that is published on Britain's " nature " weekly was pointed out, uses antibiotic might destroy the congenital immunity power of enteron aisle, and this also is the reason that causes that the antibiotic-resistant bacterium infects.Research also finds, although antibiotic can be eliminated a lot of bacteriums in the enteron aisle, the damage of the enteron aisle congenital immunity function that is caused by antibiotic therapy also provides hotbed for the breeding of antibiotic-resistant bacterium.Generally speaking, use for a long time antibiotic easily to produce drug resistance, cause feed medication and medicine for treatment amount to raise, even cause livestock and poultry to the irritated toxic reaction of antibiotic medicine; Simultaneously, antibiotic use descends Abwehrkraft des Koepers, and various bacillary and viral diseases easily occur; And the residual meeting of antibiotic in livestock products enters human body by food chain, and harm humans is healthy.
So far, there have been a plurality of countries to completely forbid gradually the use of feeding antibiotic, although China does not also enter the stage of using of completely forbidding, but consider from long-range angle, it is more and more higher that the consumer is forbidden antibiotic cry, pursuit for pollution-free, noresidue, publicly harmless animal product is also more ardent, and forbidding feeding antibiotic certainly will become the inevitable development trend of Animal Husbandry in China comprehensively.Ban use of after the feeding antibiotic; just must need to find a kind of antibiotic substitute of environmental protection; descend in order to breeding performonce fo animals decline, the immunity function that solves in the bird large-scale cultivation; and the problem such as epidemic prevention and control, alleviate the negative effect that the antibiotic forbidding brings Production of Livestock and Poultry.
At present, antibiotic substitute mainly can be summarized as five large classes: probiotics, enzyme preparation, functional oligosaccharide, organic acid preparation, Chinese herbal medicine extract.Wherein, probiotics move to maturity gradually, but still there are some problems in present existing probiotics when reality is used as a kind of comparatively popular antibiotic substitute of accepting.
The problem that existing probiotics mainly exists when using is: easy inactivation during 1. active bacteria formulation is processed, transported at feed; 2. after viable bacteria enters alimentary canal, mostly be difficult to stand the effect of hydrochloric acid in gastric juice, bile acid, low pH value, difficulty has enough quantity to reach enteron aisle or settles down enteron aisle and play a role; 3. the speed of growth is slow, be difficult to the competition of harmful enteric microorganism in the status of having the advantage; 4. bacterial classification is single, lacks compatibility research, and action effect is unilateral.Patent CN1965673 utilizes the Mixed Microbes of one or more compositions of Bacillus acidi lactici, bacillus, saccharomycete, filamentous fungi and photosynthetic bacteria, regulate the body microecological balance to reach, promote the purpose of the useful nutritional labelings such as intestinal absorption secretion multivitamin and amino acid.But the viable bacterias such as Bacillus acidi lactici are easy inactivation in feed processing, transportation, and are relatively poor to the tolerance of hydrochloric acid in gastric juice, bile acid, low pH value, and the effect during actual the use can be had a strong impact on.Patent CN 102178047A is that mixing in 1: 1: 1 forms with lactobacillus acidophilus, Lactobacillus casei and Lactobacillus plantarum by the viable count ratio, is used for alleviating the animal intestinal inflammation, and adjusting is immune, improves the growth of animal performance.These three kinds of lactobacillus are stronger for the tolerance of environment in the alimentary canal, produce sour effect better, but the bacterial classification classification are single, and effect is close, can't reach the effect of mutually replenishing, for improving the efficiency of feed utilization DeGrain.Patent 201010517542.8 forms a kind of probiotics with Miyarisan viable bacteria and acceptable carrier, Miyarisan can produce butyric acid, enzyme and vitamin, the ability that has good promotion nutrient digestion to absorb, but Miyarisan tolerance to cholate in enteron aisle is not yet clear, so the activity of Miyarisan in alimentary canal is still waiting research.

The active bacteria formulation of existing probiotics easy inactivation in feed processing, transportation after viable bacteria enters alimentary canal, is difficult to stand the effect of hydrochloric acid in gastric juice, bile acid, low pH value mostly, and difficulty has enough quantity to reach enteron aisle or settles down enteron aisle and play a role.Patent of the present invention is coated with the VREF that easily is subject to the various extraneous factor impacts in feed processing, the transportation in process of production, external environment is renderd a service the effect of viable bacteria to be reduced, guaranteed that this product has enough viable bacterias to reach enteron aisle, plays a role after entering alimentary canal.
Patent of the present invention further provides the using method of described probiotics, comprises the steps:
A: chick: 0-21 age in days, spice: 500 grams/ton mixed feed;
B: plant chicken: laying period, begin continuous use, spice: 500 grams/ton mixed feed;
Wherein, VREF (Enterococcusfaecium) belongs to a kind of in the enterococcus, is amphimicrobian lactic acid bacteria.It is not only normal bacterial classification common in the humans and animals enteron aisle, also is usually used in improving food, quality of the fodder.VREF is to be convenient to the first-selected bacterial classification producing and use with respect to strictly anaerobic, Bifidobacterium, the lactobacillus of cultivating the preservation condition harshness.1989, U.S. FDA was just announced it for can be directly used in one of bacterial classification of animal.
Li Xin etc. (2011) to 9 probiotics active variation in feed processing and storage process done a series of contrast, test and selected the bacillus of 5 strains and the lactic acid bacteria of 4 strains, wherein code name be SC be VREF.By comparing the situations such as feed mixing, feed granulating, powder storage, particulate material storage to the impact of 9 probiotics strain activity, can determine that 5 bacillus are fit to feed processing and storage.And in 4 strains of lactic acid bacteria, no matter VREF is in the situation that feed mixing, feed granulating, powder storage or particulate material are stored and all had the highest survival rate, and the survival effect significantly is better than lactobacillus acidophilus, streptococcus thermophilus, chicken enterococcus.
Used VREF (CECT410) can survive in SGF pH value 2.0 in the test of (2007) such as Nelson P é rez Guerra.Submergence can also normal growth after 120 minutes in the SGF of pH value 2.0 for VREF ANSE228 among the patent CN 201010539988.0.A large number of experiments show that, the VREF that obtains of screening can tolerate 1.0% gallbladder salinity, even up to 3.0% and the high salt of NaCl of 5%-6.5%.As seen, VREF has good stomach juice-resistant performance, and is larger by the possibility of stomach survival, and it has simultaneously good bile tolerance performance and to the tolerance of intestines and stomach against the property environment, has possessed the primary condition in the small intestine field planting.Enterococcus, especially VREF have drug resistance (Brunton, 1984 to broad-spectrum antibiotic; Murray, 1990; Woodford etc., 1995; Gold etc., 1996; Rice etc., 1996; Klare etc., 1997; Quintiliani etc., 1999; Kak etc., 2002; Klare etc., 2002).And evidence is arranged, in the time of 60 ℃, still can not examine viable bacteria through coated VREF.Great majority experiment showed, that the probiotic that is comprised of VREF can improve the body weight gains of livestock and poultry childhood. improve the price of deed.Reduce diarrhea rate, reduce the death rate.In addition, the VREF metabolism produces the materials such as organic acid, biacetyl, hydrogen peroxide, bacteriocin, and these materials have pathogen and spoilage organisms, the raising immunity of inhibition, improve the physiological function such as livestock products quality.
And but bacillus subtilis is the Direct-fed animal of China Ministry of Agriculture announcement and allows one of 16 kinds of feed grade probio bacterial classifications that use.Bacillus subtilis can stop growing under the condition of nutritional deficiency, under extreme condition, can also induce to produce the very strong endogenous spore of resistance, has the characteristics such as high temperature resistant, anti-extruding, resistance to oxidation, acid and alkali-resistance.In suitable environment, gemma can bring back to life again, and amount reproduction.
Owing to surviving in the multiple environment, bacillus subtilis has abundant product enzyme system, can utilize the multiple nutrients substance classes, can produce tens kinds of enzymes such as protease, amylase, 1,4 beta-glucanase, phytase, pectase and zytase.Bacillus subtilis can be converted into mycoprotein with the vegetable protein in the feed during the fermentation, is easilier absorbed by animal; Macromolecular albumen is converted into micromolecular little peptide, improves digestibility; Produce various enzymes, decomposition of cellulose etc., the ANFs of can also degrading simultaneously decomposes trypsin inhibitor, urase, phytolectin etc.The product enzyme effect of bacillus subtilis can promote enteron aisle to the absorption of nutriment, improves feed efficiency, reduces feedstuff-meat ratio.
Pan Kangcheng etc. (2005) studies show that, in the basal diet of broiler chicken, add 0.1% bacillus subtilis formulation after, net gain, the weight average that increases day by day are significantly increased; Feed intake and feed conversion rate also are significantly improved; Chicken meat quality and amino acid composition then have clear improvement.According to (2009) such as Xu Haiyan, adding bacillus in the diet has the function that promotes that chick thymus gland, spleen and the bursa of farbricius are grown, and can significantly improve IgG content in the serum, strengthens the anti-stress ability of animal.And compare with single use bacillus subtilis, many bacterial classifications cooperate therapy more comprehensive, effective.Simultaneously, because bacillus subtilis has very strong biological assimilation, therefore can be applicable to remove the ight soil stench of livestock and poultry farm, its metabolite also has inhibitory action to the growth and breeding of mosquitos and flies.
The probiotics of patent of the present invention has following beneficial effect:
1, the beneficial bacterium among the present invention can improve feed intake, daily gain and the feed conversion rate of chick, aspect the reduction death rate significant effect is being arranged.
2, the beneficial bacterium among the present invention can improve the reproductive performance of kind of chicken, plants the performances such as laying rate of chicken, fertility rate of hatching egg, incubation rate, strong young rate and all increases significantly.
3, the VREF among the present invention can fast breeding and carries out the occupy-place effect, sets up the dominant microflora of intestinal beneficial bacterium.Simultaneously, the VREF among the present invention can secrete lactic acid, suppresses breeding and the growth of pathogen, regulates the microecological balance of body enteron aisle before stress occuring, improve to stress resistivity, reduces sick of follow-up infection.
4, the bacillus subtilis among the present invention can promote the Development of Immune Organs of fowl, strengthens immunity of organisms; Produce enzyme and antibacterial peptide, suppress the pathogenic bacteria breeding; Improve poultry, birds, beasts and eggs product quality.
5, the oligosaccharides among the present invention can promote the Fast-propagation of beneficial bacterium, further enlarges the flora advantage of beneficial bacterium, and vitamin is improved anti-stress ability and shorten the treatment effect of the course for the treatment of, reduces case fatality rate and reduces the sick rate of washing in a pan.
