Abstract
The invention provides a kind of nursery pig concentrated feed, belong to a kind of field of animal feed, nursery pig concentrated feed of the present invention adopts the substitute antibiotics compound be made up of antibacterial peptide, plants essential oil and acidulant to carry out substitute antibiotics.The pure green safety of feed of the present invention is nuisanceless, and can not damage the immunity of swinery, avoids disastrous effect and serious food security crisis that pig difficulty that the excessive interpolation of antibiotic causes supports.
Description
Technical field
The present invention relates to a kind of animal feed, particularly a kind of nursery pig concentrated feed.
Background technology
Along with China's large-scale degree of raising pigs improves rapidly, cultivation density increases, and for increasing economic efficiency to greatest extent, antibiotic is widely used as feed growth-promoting additive always.Add antibiotic in feed after, the speed of growth and the efficiency of feed utilization of animal improve 5% to 10%, and for control disease generation, reduce diarrhoea aspect there is good effect.Animal husbandry was once consuming the antibiotic dosage of global half.But because the situation that antibiotic overdose, super kind were added in recent years remains incessant after repeated prohibition, and there is further serious gesture.Antibiotic Use out of range brings a lot of problem, the responsibility of such as food-safety problem, enterprise and the infringement of image, the problem such as piglet hair color is mixed and disorderly, late growing stage is obviously suppressed.Although antibiotic application facilitates the development of animal husbandry, allow more people buy more meat products with cheap price, bring global Health risk---popular death threats brought of drug-resistant bacteria.According to the saying of CPMA hospital infection control association General Board Hu Bijie, China is every year because of nearly 500,000 people of death toll that bacterial resistance causes.
Sweden announced to completely forbid in 1986 to use antibiotic for the first time in animal and fowl fodder, and in January, 2006 plays European Union and completely forbids use antibiotic especially.Japan just started to forbid the use of all antibiotic in feed from 2008.Korean government also completely forbade and add antibiotic in animal feed from 1 day July in 2011.On December 11st, 2013 FDA (Food and Drug Adminstration) (FDA) official sources, FDA is implementing to forbid in animal feeding process to accelerate to use antibiotic way for the purpose of growth of animal.In China, the Ministry of Agriculture has issued the measures such as No. 168 bulletin, carries out strict restriction and specification to the antibiotic kind of use, dosage, and antibiotic medicine monitoring is included in legal management track.In future, whole world forbidding antibiotic becomes a kind of trend, and therefore the green safety nuisance free feed supplement of development of new carrys out the inexorable trend that the use of substitute antibiotics is current animal husbandry development.
Summary of the invention
According to demand and the deficiency in above-mentioned field; the invention provides a kind of concentrated feed for nursery pig; feed antibacterial peptide of the present invention, plants essential oil and acidulant reasonable compatibility substitute antibiotics; the pure green safety of feed of the present invention is nuisanceless; and the immunity of swinery can not be damaged, avoid disastrous effect and serious food security crisis that pig difficulty that the excessive interpolation of antibiotic causes supports.
Technical scheme of the present invention is as follows:
A kind of nursery pig concentrated feed, it is characterized in that, described nursery pig concentrated feed adopts the substitute antibiotics compound be made up of antibacterial peptide, plants essential oil and acidulant to carry out substitute antibiotics.

Antibacterial peptide is the owned a kind of polypeptide with antibacterial activity produced through induction in animal body, has broad spectrum antibacterial, innate immunity characteristic, is proved to be and has good killing action to multiple gram-positive bacteria and negative bacterium.By acting on the cell membrane of bacterium, causing perforation, destroying the ion channel of bacterium, finally cause thalline self-dissolving and dead, and antibiotic has equal effect, but the generation of noresidue and drug resistance.
Acidulant by reducing intestines and stomach pH value, can keep best digestive environments on the one hand, changes harmful bacteria and is suitable for living environment, promote the increment of beneficial bacterium.On the other hand, in feed, add acidulant, the breeding of mould in feed can be prevented, keep freshness, improve the utilization rate of feed palatability and nutriment.
The antibacterial mechanisms of plants essential oil is roughly considered to after hydrophobic aromatic oil enters cell, destroy membrane structure, cause bacterial cell to break, thus play antibacterial action.Be considered to the strongest at extracts such as antibiosis, garlics, only dysentery grass, wild marjoram.
The invention provides the nursery-stage pig feed of a kind of antibacterial peptide, plants essential oil and acidulant reasonable compatibility substitute antibiotics.Child care pig because of stress, very easily there is the early stage syndromes of ablactation such as diarrhoea, growth retardation in the change such as digestive physiology, immune factor and gastrointestinol microorganism flora, has a strong impact on piglet healthy and grow.This stage, the antibiosis of the most of feed interpolation high dose in market usually avoids the generation of above-mentioned symptom, endurance strain increases year by year on the one hand, and worse and worse, piglet easily occurs that fur is mixed and disorderly, late growing stage is obviously suppressed to the effect of control bacteriosis on the other hand.The present invention uses antibacterial peptide dominant mechanism to be cell membrane to bacterium, causes perforation, destroys the ion channel of bacterium, finally cause thalline self-dissolving and dead, have equal effect with antibiotic, extremely difficulty forms the resistance to the action of a drug in animal body, has the plurality of advantages such as broad spectrum antibacterial and drug residue free.The constituent of antibacterial peptide is easily by amino acid that animal digests and assimilates.Antibacterial peptide gene is transferred in livestock and poultry specific cells, strengthens immunity of organisms, can not produce drug-fast bacteria, is used for treating the various thorny diseases such as piglet pest, diarrhea of pigs, has no side effect and noresidue.The plants essential oil used in the preferred embodiments of the present invention is the plants essential oil through experiment sieving, nucleus is origanum oil mainly, and the mechanism of action of origanum oil is also the mode by perforate membrane and film bonding, makes membranolysis, intracellular organic matter is excessive, kills harmful bacteria.Large quantity research shows, origanum oil all can effectively suppress enteropathogenic E. Coli, salmonella, staphylococcus, streptococcus, well maintains intestinal health, prevents diarrhea.On the other hand, origanum oil has facilitation to alimentary canal endothelial cell, accelerates the renewal of enteron aisle fine hair, reduces that pathogen is attached to be planted, and promotes nutrient absorption.The present invention adopts the compound acidulant of high dose, reduces intestines and stomach pH value, the VFAs such as propionic acid, reduces pH value in born of the same parents rapidly, suppresses the metabolism such as DNA, RNA, kill harmful bacterium.The non-volatile organic acids such as lactic acid, by reducing the pH value between kytoplasm, destroy pathogen osmotic pressure system, stop cell normally to be bred.The present invention selects antibacterial peptide, plants essential oil, compound acidulant three kinds of raw materials by different metabolic pathway kill harmful bacterium by testing sieve, establishes multiple defense barrier, the diarrhea rate of child care pig and the death rate are declined greatly.
The present invention easily absorbs high energy source and is selected from the energy source that popcorn, flour, soybean oil, fatty powder and glucose etc. easily absorbs, provides energy fast.Because child care pig body fat content lacks most, research shows, the child care pig body fat content after one week that weans drops sharply to 7% from 15%, but the digestive system undeveloped mature of at this moment piglet, endogenous digestive ferment hyposecretion.The raw material select easy absorption, providing energy fast can well adapt to its intestines and stomach, and added body internal loss fast.Popcorn can make that amylum body breaks, starch gelatinization, and Vitro Digestibility can bring up to 80% from 18%, overcomes ablactation stress.Model etc. report that popcorn can improve average daily gain and the feedstuff-meat ratio of the rear 14 ~ 25d and 0 ~ 25d of wean.Fatty powder adopts special process that aliphatic acid is formed and more balances, and has good water-soluble, is more beneficial to child care pig and digests and assimilates.Lipomicron on the other hand after enzymolysis, shearing, emulsification, homogeneous can be converted into ketoboidies by very fast absorption, and ketoboidies is easy to by child care pig synthctic fat.
Present protein source is selected from dehulled soybean meal, expanded soybean, fermented bean dregs, fish meal.A part of dregs of beans is replaced with expanded soybean and fermented bean dregs.Fermented bean dregs fully eliminates ANFs, trypsin ihhibitor and agglutinin content all extremely low, soybean antigen all decomposes, and avoids the GI infringement of these factor pair child care pigs.And be rich in a large amount of prebiotics bacteria, promote the propagation of profitable strain, suppress harmful bacteria, protect the intestines and stomach of child care pig.Activate Endogenous Growth Factors and immune-regulating factor, strengthen child care pig resistance against diseases.And fermented bean dregs aromatic flavour, good palatability, can improve feed intake.Expanded soybean starch burn degree reaches 40-50%; Eleocyte breaks, and makes it more easily contact lipase, thus increases capacity usage ratio, also makes free fatty acid content increase; And reduce the content of trypsin ihhibitor, and have better destruction to two kinds of antigenic substances of soybean protein, greatly reduce grice diarrhoea, improve production performance.
Organic calcium source of the present invention be calcium lactate or/and calcium formate, good palatability, not only as good calcium complement agent, simultaneously or a kind of high-quality acidulant, reduces the use amount that antibiosis is answered.
The present invention not only uses the fat source of absorption easy to digest, and with the addition of fat digestion promoter breast energy or/and l-cn, promotes digesting and assimilating of piglet further.The nucleus of breast energy is bile acid, not only plays the effect of auxiliary lipase, can strengthen the activity of lipase simultaneously.Improve child care pig digesting and assimilating fat.On the other hand, bile acid or a kind of effective bactericide, prevent food from rotting and fermentation at stomach, therefore greatly reduce the diarrhoea of piglet.L-cn in aliphatic acid beta oxidation process as the mechanism of action of carrier transport aliphatic acid by mitochondrial membrane; play an important role in piglet fat metabolism; and acyl group and lactic acid in purged body; prevent the toxicity of the excessive generation of ammonia in body; and as biological anti-oxidant scavenging free radicals, stress of baby pigs caused ablaction may be greatly reduced.
Inventor is by a large amount of animal experiment, the raw material of substitute antibiotics is screened, optimize antibacterial peptide, plants essential oil, acidulant rational proportion, substitute the antibiotic such as colistin, virginiamycin in feed completely, reduce weanling pig because of stress, the change such as digestive physiology, immune factor and gastrointestinol microorganism flora and the diarrhoea, growth retardation etc. that occur weans early stage syndrome and the generation of noresidue and drug resistance.Not only can be solved the problem by antibacterial peptide, plants essential oil and acidulant reasonable compatibility, and the present invention is by antibacterial peptide, plants essential oil, acidulant reasonable compatibility, replace antibiotic use, for reducing medicament residue, reduction bacterial drug resistance provides best solution.
