Description
Technical field
The present invention relates to a kind of additive for feed for porkets and preparation method thereof, particularly a kind of can improve efficiency of feed utilization and reduce the wean of sucking pig diarrhea rate after additive for feed for porkets and preparation method thereof.
Background technology
At present, Animal Husbandry in China is in the high-speed developing period, but also exists some problems in high speed development.For example, during Pig Industry is produced, due to breeding environment and the hysteresis of cultural technique level, make animal in breeding growth course, be difficult to its due hereditary potential of performance.For the best production performance of performance sow, minimizing sucking pig disease infect 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 bringing by liquid breast milk stress; Sucking pig separates with dam the psychological stress causing suddenly; And again build the environmental stress that in group and grade status deterministic process, the fight between sucking pig individuality causes.Nutrition, psychology and environment are triple stress inevitably increase the sensitiveness of the rear sucking pig of wean to potential pathogenic microorganism in environment, after causing weaning, under sucking pig diarrhoea, feed intake decline, dysphoria, aggressive reinforcement, growth retardation, concurrent oedema and premunition, degradation comprehensively stress, more easily there is archenteric flora imbalance, cause that alimentary canal normal flora is destroyed, the pathogenic strain amount reproductions such as Escherichia coli, Salmonella cause 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.The stagnation that stress often follow growth of suckling pigs of wean sucking pig, produces cad pig when situation is serious, even cause sucking pig death, causes tremendous economic loss to Swine Production industry.
For a long time, antibiotic guarantee animal health, promote growth, save feed and increase economic efficiency aspect play very important effect, but long-term a large amount of abuse of antibiotics meeting brings problems, as pathogen produces drug resistance, limit the performance of animal immune function, reduced immunity and the premunition of animal, suppressed the growth of animal intestinal beneficial bacterium, destroy intestinal microecology balance, the growth of restriction animal.A lot of research shows, if the mankind are the meat product of edible antibiotic excess residual for a long time, will make the mankind create antagonism and give birth to plain drug resistance, this not only can produce so-called ' resistance baby ', ' superbacteria ', and existence brings serious threat to human health, therefore, a lot of national uses of forbidding one after another or limiting feeding antibiotic in the world.European Union was from 1 day January in 2006, completely forbid and in animal feed, use antibiotic, Japan just forbade using in all antibiotic animal feeds since 2008, Korean government completely forbade and animal feed, adds antibiotic from July 1st, 2011, and I am in state's feedstuff industry, in additive for feed for porkets, a large amount of antibiotic phenomenons of adding are still commonplace, cause in animal generation drug resistance or the resistance to the action of a drug, Immune Dysfunction, resistance against diseases decline, pork and have the problems such as antibiotic residue, brought fear to people's life.In addition, because trace element plays very crucial effect in growth of animal and intestinal health control, excessive interpolation phenomenon also ubiquity, especially copper and zinc in feedstuff industry.And because traditional inorganic microelement digestive utilization ratio is low, excessive interpolation certainly leads to excessive emissions, this not only causes waste, and gives environment, and the red tide of sea and the malicious grain phenomenon that occur in recent years 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 piglet preweaning feed generally contains the high-quality feed raw material (as milk powder, SDPP, goldbeater's skin albumen etc.) of higher level in Swine Production, and excess is added antibiotic growth-promoting additive and the extra additive (as acidulant, enzyme, emulsifying agent etc.) that supplements regulating intestinal canal health.But ubiquity, and efficiency of feed utilization is not high, the dissatisfactory problem of suckling pig growth and development situation, and this has not only increased raiser's production cost, and nutritional labeling is discharged in environment in a large number, has caused the huge wasting of resources and environmental protection pressure.The utilization rate that improves feed has also become the demand of building a conservation-minded society.
CN 103053854A a kind of sucking pig Antistress agent and preparation method are disclosed and sucking pig is anti-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 salt fine powder, the salt after refinement is sieved mixes with corn α-starch; After successively adding VitAVitE, mix; After adding glucose, lactose, mix.CN 103125773A discloses a kind of for repairing the composite feed additive of 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.Above-mentioned two patent applications all exist the long-term gaining effect of sucking pig not good, the defect that efficiency of feed utilization is not high.
Summary of the invention
After sucking pig wean, be prone to diarrhoea, cause the feed intake after sucking pig wean and grow to be affected, cause tremendous economic loss to cultivation industry.Existing piglet feed or additive for feed for porkets all well do not address the above problem, and a large amount of antibiotic of interpolation have simply had a strong impact on the upgrowth situation of sucking pig and raiser's confidence.In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of new additive for feed for porkets, in this additive, do not contain antibiotic completely, it is take probio and amino acid etc. as main component, after adding in piglet feed, can greatly alleviate the diarrhea rate after sucking pig wean, and can significantly improve the utilization rate of feed, improve the growth and development state of sucking pig, be adapted at applying in aquaculture.
