Abstract
The invention provides a nursing pig concentrated feed and belongs to the field of animal feeds. According to the nursing pig concentrated feed, an antibiotic is replaced by an antibiotic-substituting compound consisting of antimicrobial peptides, plant essential oil and an acidifying agent. The feed is purely green, safe and harmless, the immunity of pigs cannot be destroyed, and difficult pig breeding and severe food safety crisis which are caused by the excessive addition of the antibiotic are avoided.
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.In feed, add after antibiotic, the speed of growth of animal and efficiency of feed utilization have improved 5% to 10%, and have good effect for generation, the reduction diarrhoea aspect of controlling disease.Animal husbandry had once consumed 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 problems, problem that infringement, the piglet hair color of the such as responsibility of food-safety problem, enterprise and image are mixed and disorderly, late growing stage is obviously suppressed etc.Although antibiotic application has promoted the development of animal husbandry, allow more people buy more meat products with cheap price, brought a global healthy crisis---the popular death threats that bring of drug-resistant bacteria.According to the saying of the General Board Hu Bijie of CPMA hospital infection control association, nearly 500,000 people of death toll that China causes because of bacterial resistance every year.
Sweden announced to completely forbid in 1986 in animal and fowl fodder, to use antibiotic for the first time, and play European Union and completely forbid especially use antibiotic in January, 2006.Japan just forbade the use of all antibiotic in feed since 2008.Korean government also completely forbade and animal feed, adds antibiotic from 1 day July in 2011.FDA (Food and Drug Adminstration) on December 11 (FDA) official sources in 2013, FDA is implementing to forbid take quickening growth of animal as object, to use antibiotic way in animal feeding process.In China, the Ministry of Agriculture has issued the measures such as No. 168 bulletin, to using antibiotic kind, dosage to carry out strict restriction and standard, antibiotic medicine monitoring is included in to legal management track.In future, forbidding antibiotic in the whole world becomes a kind of trend, and therefore to carry out the use of substitute antibiotics be the inexorable trend of current animal husbandry development to the green safety nuisance free feed supplement of development of new.

Antibacterial peptide is the owned a kind of polypeptide with antibacterial activity producing through induction in animal body, has broad spectrum antibacterial, innate immunity characteristic, is proved to be multiple gram-positive bacteria and negative bacterium are had to good killing action.By acting on the cell membrane of bacterium, cause perforation, destroy the ion channel of bacterium, finally cause thalline self-dissolving and death, and antibiotic has equal effect, but the generation of noresidue and drug resistance.
Acidulant can, by reducing intestines and stomach pH value, keep best digestive environments on the one hand, changes the suitable living environment of harmful bacteria, promotes the increment of beneficial bacterium.On the other hand, in feed, add acidulant, can prevent the breeding of mould in feed, 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, causes bacterial cell to break, thereby plays antibacterial action.At antibiosis, garlic, only the extract such as dysentery grass, wild marjoram is considered to the strongest.
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, the change very such as digestive physiology, immune factor and intestines and stomach microorganism species is prone to the early stage syndromes of ablactation such as diarrhoea, growth retardation, has a strong impact on the healthy and growth of piglet.This stage, the antibiosis of the most of feed interpolation high dose in market is usually avoided the generation of above-mentioned symptom, on the one hand endurance strain increases year by year, and worse and worse, piglet easily occurs that fur is mixed and disorderly, late growing stage is obviously suppressed etc. to the effect of control bacteriosis on the other hand.It is the cell membrane to bacterium that the present invention uses antibacterial peptide dominant mechanism, causes perforation, destroys the ion channel of bacterium, finally cause thalline self-dissolving and death, 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 the amino acid of easily being digested and assimilated by animal.Antibacterial peptide gene is proceeded 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 using in the preferred embodiments of the present invention is the plants essential oil through experiment sieving, nucleus is mainly origanum oil, and the mechanism of action of origanum oil is also by perforate membrane and the bonding mode of film, makes membranolysis, intracellular organic matter is excessive, kills harmful bacteria.Quantity research shows greatly, and 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, has reduced intestines and stomach pH value, and the VFAs such as propionic acid reduce rapidly pH value in born of the same parents, suppress 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, three kinds of raw materials of compound acidulant by different metabolic pathway kill harmful bacterium by testing sieve, has set up multiple defense barrier, and 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 popcorn, flour, soybean oil, fatty powder and glucose etc. and easily absorbs, provide energy fast energy source.Because child care pig body fat content lacks most, research shows, after weaning one week, child care pig body fat content drops sharply to 7% from 15%, but the digestive system undeveloped mature of piglet at this moment, endogenous digestive ferment hyposecretion.The intestines and stomach of selecting easy absorption, providing the fast raw material of energy can well adapt to it, 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.The report popcorns such as Model can improve average daily gain and the feedstuff-meat ratio of the rear 14~25d of wean and 0~25d.Fatty powder adopts special process to make aliphatic acid form more balance, and has good water-solublely, is more beneficial to child care pig and digests and assimilates.Lipomicron after enzymolysis, shearing, emulsification, homogeneous can and be converted into ketoboidies by very fast absorption on the other hand, and ketoboidies is easy to by child care pig synthctic fat.
Protein source of the present invention is selected from dehulled soybean meal, expanded soybean, fermented bean dregs, fish meal.Replace a part of dregs of beans with expanded soybean and fermented bean dregs.Fermented bean dregs is fully eliminated ANFs, and trypsin ihhibitor and agglutinin content are all extremely low, and soybean antigen all decomposes, and has avoided the GI infringement of these factor pair child care pigs.And be rich in a large amount of prebiotics bacterias, and promote the propagation of profitable strain, suppress harmful bacteria, protected 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, thereby increases capacity usage ratio, also makes free fatty acid content increase; And the content of reduction trypsin ihhibitor, and two of soybean protein kinds of antigenic substances are had to better destruction, greatly reduce grice diarrhoea, improve production performance.
Organic calcium of the present invention source is calcium lactate or/and calcium formate, and 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 has added fat digestion promoter breast energy or/and l-cn further promotes digesting and assimilating of piglet.The nucleus of breast energy is bile acid, not only plays the effect of auxiliary lipase, can strengthen the activity of lipase simultaneously.Improved child care pig digesting and assimilating fat.On the other hand, bile acid or a kind of effectively bactericide, prevent that food from rotting and fermentation at stomach, therefore greatly reduces the diarrhoea of piglet.L-cn in aliphatic acid beta oxidation process as carrier transport aliphatic acid by the mechanism of action of mitochondrial membrane; in piglet fat metabolism, play an important role; and the interior acyl group of removing body and lactic acid; prevent the toxicity of the excessive generation of ammonia in body; and may remove free radical as biological anti-oxidant, greatly reduce stress of baby pigs caused ablaction.
Inventor is by a large amount of animal experiments, raw material to substitute antibiotics screens, optimize antibacterial peptide, plants essential oil, acidulant rational proportion, substitute the antibiotic such as colistin in feed, virginiamycin completely, reduced weanling pig because of stress, digestive physiology, immune factor and intestines and stomach microorganism species etc. change the early stage syndromes of weaning such as the diarrhoea that occurs, growth retardation, and the generation of noresidue and drug resistance.By antibacterial peptide, plants essential oil and acidulant reasonable compatibility, not only can address the above problem, and the present invention is by antibacterial peptide, plants essential oil, acidulant reasonable compatibility, replace antibiotic use, for minimizing medicament residue, reduction bacterial drug resistance provide best solution.
