Description
Technical field
The present invention relates to a kind of additive for feed for porkets and preparation method thereof, particularly a kind ofly can improve efficiency of feed utilization and additive for feed for porkets and preparation method thereof after reducing the wean of sucking pig diarrhea rate.
Background technology
At present, Animal Husbandry in China is in the high-speed developing period, but also there are some problems while high speed development.Such as, Pig Industry produce in, due to breeding environment and cultural technique level delayed, make animal in flourish process be difficult to play its due hereditary potential.For playing the best production performance of sow, reducing sucking pig disease infection probability and improve sucking pig production performance, often adopt segregated early weaning technology.The digestive system of early weaned piglets is not yet grown perfect, be difficult to bear convert to cereal solid feed the nutrition brought by liquid breast milk stress; Sucking pig and dam are separated the psychological stress caused suddenly; And again build the environmental stress that the fight in group and grade status deterministic process between sucking pig individuality causes.Nutrition, psychology and environment are triple inevitably stress increase the rear sucking pig of wean to the sensitiveness of pathogenic microorganism potential in environment, sucking pig diarrhoea after causing weaning, feed intake decline, have the fidgets, aggressive reinforcement, growth retardation, degradation comprehensively stress under concurrent oedema and premunition, more easily there is archenteric flora imbalance, cause alimentary canal normal flora to be destroyed, the pathogenic strain such as Escherichia coli, Salmonella amount reproduction causes bacillary enteritis.Research shows, pig be the most easily stress animal species, and in intensive culture process, wean be again the most easily bring out sucking pig stress key link.Wean sucking pig stress often with the stagnation of growth of suckling pigs, produce cad pig when situation is serious, even cause sucking pig dead, cause tremendous economic to lose to Swine Production industry.
For a long time, antibiotic is at guarantee animal health, growth promoting effects, saving feed and play very important effect in increasing economic efficiency, but long-term a large amount of abuse of antibiotics can bring problems, as pathogen produces drug resistance, limit the performance of animal immune function, reduce immunity and the premunition of animal, suppress the growth of animal intestinal beneficial bacterium, destruction intestinal microecology balances, the growth of restriction animal.A lot of research shows, if the mankind eat the meat product of antibiotic excess residual for a long time, the mankind will be made to create antagonism and to give birth to the drug resistance of element, this not only can produce so-called ' resistance baby ', ' superbacteria ', and bring serious threat to human health existence, therefore, a lot of country forbids or limits the use of feeding antibiotic one after another in the world.European Union was from 1 day January in 2006, completely forbid and use antibiotic in animal feed, Japan from 2008 just forbid using in all antibiotic animal feeds, Korean government completely forbids from July 1st, 2011 and add antibiotic animal feed, and I am in state's feedstuff industry, in additive for feed for porkets, a large amount of antibiotic phenomenon of adding is still commonplace, cause that animal produces drug resistance or the resistance to the action of a drug, immunologic function reduces, resistance against diseases declines, have the problems such as antibiotic residue in pork, bring fear to people's life.In addition, because trace element plays very crucial effect, excessive interpolation phenomenon also ubiquity in feedstuff industry, especially copper and zinc in growth of animal and intestinal health control.And due to traditional inorganic microelement digestive utilization ratio low, excessive interpolation certainly leads to excessive emissions, and this not only causes waste, and give environment, the red tide of sea occurred in recent years and malicious grain phenomenon all follow animal husbandry relevant.Therefore, provide that a kind of diarrhea rate is low, digestive utilization ratio is high, feed intake and grow comparatively well suited under intensive culture pattern non-antibiotic class environment-protecting feed or environment-protecting feed additive seem particularly important.
In addition, although the high-quality feed raw material (as milk powder, SDPP, intestine membrane protein etc.) of piglet preweaning feed generally containing higher level in Swine Production, and excess adds antibiotic growth-promoting additive and the extra additive (as acidulant, enzyme, emulsifying agent etc.) supplementing regulating intestinal canal health.But ubiquity, and efficiency of feed utilization is not high, the dissatisfactory problem of suckling pig growth and development situation, this not only adds the production cost of raiser, and a large amount of nutritional labeling is discharged in environment, causes the huge wasting of resources and environmental protection pressure.The utilization rate improving feed has also become the demand of building a conservation-minded society.
CN 103053854A discloses a kind of sucking pig Antistress agent and preparation method and sucking pig resisting stress water.Sucking pig Antistress agent, in every 500g Antistress agent, each composition is: vitamin A, vitamin E, corn α-starch, lactose, glucose, salt.By broken for salt fine powder, refinement sieve after salt mix with corn α-starch; Mix after successively adding VitAVitE; Mix after adding glucose, lactose.CN 103125773A discloses a kind of composite feed additive for repairing sucking pig intestinal mucosa injury, and this feed addictive comprises: glutamine 0.1-0.2 part, butyric acid 0.01-0.1 part, yeast nucleic acid 0.01-0.1 part, threonine 0.02-0.2 part, origanum oil 0.03-0.3 part, chitosan oligosaccharide 0.03-0.3 part, active dry yeast 0.1-0.5 part, bacillus subtilis 0.1-0.5 part, vitamin 0.11-0.3 part, carrier 5-7.5 part.It is not good all to there is the long-term gaining effect of sucking pig in above-mentioned two pieces patent application, the defect that efficiency of feed utilization is not high.
Summary of the invention
Easily occur diarrhoea after sucking pig wean, the feed intake after causing sucking pig to be weaned is affected with growing, and causes tremendous economic to lose to cultivation industry.Existing piglet feed or additive for feed for porkets all well do not solve the problem, and a large amount of antibiotic of interpolation has simply had a strong impact on the upgrowth situation of sucking pig and the confidence of raiser.In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of new additive for feed for porkets, completely not containing antibiotic in this additive, its with probio and amino acid etc. for main component, add the diarrhea rate after greatly can alleviating sucking pig wean after in piglet feed to, and the utilization rate of feed can be significantly improved, improve the growth and development state of sucking pig, be adapted at applying in aquaculture.
A kind of for reducing sucking pig diarrhea rate after wean and the feed addictive improving efficiency of feed utilization, it comprises the following raw material according to weight parts: Bifidobacterium 0.1-0.5 part, bacillus subtilis 0.1-0.5 part, active dry yeast 0.1-0.5 part, arginine 0.1-0.2 part, branched-chain amino acid 0.2-0.7 part, glutamic acid 0.1-0.3 part, glutamine 0.1-0.2 part, tryptophan 0.1-0.2 part, glycine 0.1-0.2 part, taurine 0.03-0.3 part, CLA (CLA) 0.05-0.4 part, DHA (DHA) 0.1-0.5 part, eicosapentaenoic acid (EPA) 0.1-0.3 part, glucose oxidase 0.5-1 part, lactic dehydrogenase 0.3-0.8 part, Immunoglobulin IgG 0.2-0.4 part, vitamin 0.15-1 part, environmental protection organic trace element 0.5-0.9 part, environmental protection organic acidulant 0.3-0.5 part, pepsin 1.5-2 part, trypsase 1.5-2 part.
Wherein said trace element mainly contains copper, iron, zinc, manganese and selenium, and wherein copper iron zinc-manganese selects amino acid or small-peptide chelated salt; Culture propagation product yeast selenium selected by selenium salt.
Bifidobacterium Bifidobacterium is the Gram-positive bacillus by French scholar Tissier isolated a kind of anaerobism from the ight soil of breast milk nutrition youngster in 1899, and end is bifurcated usually, therefore named Bifidobacterium.Because recent two decades comes the emergence of microecology and the progress of Medical Revolution, the importance that Bifidobacterium is studied more and more is familiar with.Because Bifidobacterium goods are able to extensive use at world wide, broad masses have recognized that its importance.Particularly can provide unique protective effect for the intestinal health of infant, effectively reduce the incidence of disease of infant's enteric infection.The Main Function of Bifidobacterium and extensive use, also for the basis of development has been established in the research of Bifidobacterium.Through the continuous explorative experiment of numerous experts and scholars, confirm that Bifidobacterium is flora the most useful in intestines.The Bifidobacterium confirmed at present has following beneficial effect to animal body: 1. protect health not by the infection of pathogen.A large amount of Bifidobacteriums is perched in the intestines of Healthy People.Most typical representative, is breast-fed baby, and their intestinal bacterium clump 99% is all Bifidobacterium.Because Bifidobacterium can produce acetic acid and lactic acid, so the pH value deflection highly acid in intestines, therefore can suppress the breeding of pathogen, prevent human body to be infected.Drink the baby of baby than drink milk of breast milk, less generation diarrhoea or enteritis, the death rate is also lower, and reason just here; Certainly, not only baby is like this, even if child and adult are too.Bifidobacterium is more preponderated in intestines, is more not easy to suffer the intrusion of pathogen and catches.2. situation corrupt in intestines is suppressed.When protein is decomposed by bad bacterium in intestines, the corrupt substances such as amine, ammonia, indoles (indole), hydrogen sulfide can be formed.After these materials are absorbed by the body, namely become the reason of the various diseases such as constipation, diarrhoea, cancer, hypertension, and accelerate the aging of health.As above-mentioned, the reason that ight soil can stink, is also these corrupt substances.If Bifidobacterium and bad bacteriological operation are won, situation corrupt in intestines just can be suppressed.3. vitamin is manufactured.Suppressing the corruption in intestines, can't be the major function of Bifidobacterium.Bifidobacterium can produce the elements such as Aneurine, B6, B12, K12, nicotinic acid and iodine really.Wherein some can absorb in body, has greatest benefiting to human body.4. promote the wriggling of intestines, prevent the generation of constipation.When Bifidobacterium breeds in intestines, the organic acid such as lactic acid or acetic acid will be produced, as metabolite.Can promote that intestines are wriggled, and prevent constipation.5. prevention and therapy diarrhoea.If intestinal bacterium clump disequilibrium, will cause bacteroidal diarrhoea sometimes.Bifidobacterium can breed in intestines, namely represents that intestinal bacterium clump has kept normal balance.Therefore, can anti-diarrhea in advance; Even if suffering from diarrhea, if Bifidobacterium can be made to increase, also fully diarrhoea can treated.6. the immunity of health is improved.In the thalline of Bifidobacterium, containing stimulating immunity function in body, improve the material of immunity.It is generally acknowledged, the Bifidobacterium in intestines can be dissolved because of oneself, makes the composition of thalline by body absorption, and contributes to the raising of immunocompetence.7. decompose carcinogenic substances.The bad bacterium making COF be transformed into the carcinogens such as nitrosamine is there is in intestines.But then, Bifidobacterium but has the effect of decomposing certain nitrosamine, and this is the proof obtained according to tube assay.
Bacillus subtilis is the one of bacillus.Now verified bacillus subtilis have act on as follows produce in 1. bacillus subtilis thalli growth process subtilin, polymyxins, nystatin, gramicidins isoreactivity material, the conditioned pathogen of these active materials to pathogenic bacteria or autogenous infection has obvious inhibitory action.2. bacillus subtilis consumes rapidly the free oxygen in environment, causes enteron aisle hypoxemia, promotes that useful anaerobic bacteria grows, and produces the organic acids such as lactic acid, reduces enteron aisle pH value, indirectly suppresses the growth of other pathogenic bacteria.3. the growing of stimulating animal immune organ, activates T, bone-marrow-derived lymphocyte, improves immunoglobulin (Ig) and antibody horizontal, strengthens cellular immunity and humoral immune function, improves herd immunity.4. bacillus subtilis thalline self synthesizes the enzymes such as AMS, protease, lipase, cellulase, together plays a role in alimentary canal with the digestive enzymes in animal body.5. can the multiple B family vitamin such as synthetic vitamin B1, B2, B6, nicotinic acid, improve the activity of interferon and macrophage in animal body.
Active dry yeast is the dry ferment goods still being kept strong fermentability by the yeast cake of specific culture after squeezing drying and dehydrating.Compressed years are squeezed into fine strip shape or coccoid, utilize the circulating air of low humidity through fluid bed continuous drying, the moisture that makes finally to ferment reaches about 8%, and keeps the fermentability of yeast.Active dry yeast is the probio that U.S. FDA (1999) regulation allows to feed, the probiotic kind that the approval in 1999 of the Ministry of Agriculture of Ye Shi China uses.Research finds that active dry yeast can not only improve the quantity of Rumen Cellulolytic Bacteria, reaches the object improving nutrient digestion utilization rate, also can promote the propagation of lactic acid bacterium number simultaneously, maintains the normal function of cud.
It is the product utilizing Ipomoea batatas, pachyrhizus, sucrose or wheat to adopt fermentation method production that organic acidulant citric acid has another name called citric acid.First in the brewer's wort of 4 ~ 6 Baume degrees, add the agar of 25% to 30%, then add aspergillus niger strain, cultivate under 30 ~ 32 DEG C of conditions and within about 4 days, obtain cultivating bacterium, then access corresponding raw material and carry out fermentation leaching and form.Acidulant has pH value in reduction stomach, improves digestive enzyme activity, delays stomach mass rate of emission, promotes the function of nutrient absorption, and it can also improve enteron aisle acidity simultaneously, suppresses harmful bacteria to be bred, and regulation and control gut flora balance, reduces disease of digestive tract.When adding in wean piglet feed, can improve feed acidity, stimulating wean sucking pig salivary secretion, this acid and sweet animal, can improve palatability, increase feed intake concerning natively liking undoubtedly.
