Abstract
The invention discloses a poplar tree extract feed additive and a preparation method thereof. The preparation is prepared by making extract of flowers and barks of poplar trees by various means and mixing the extract with a carrier uniformly. The preparation method comprises the following steps: 1, performing primary extraction on flowers and barks of poplar trees; and 2, performing secondary circulating extraction on residue obtained after the extraction in the step 1, subjecting the extract obtained at two times to spray drying treatment, and uniformly mixing the dried extract with the carrier uniformly to obtain the poplar tree extract feed additive. The feed additive has antibacterial, antiphlogistic and animal immunity-improving functions.
Description
Technical field
The present invention relates to a kind of willow extract feed additive and preparation method thereof, have anti-inflammation, improve the function of animal immunizing power, belong to natural plants additive technology field.
Background technology
Various age pig particularly the breathing problem of piglet be feature, existing one of the main eqpidemic disease of large-scale pig farm that become.Wherein present topmost PRDC (PRDC) is the disease of feature with speed of growth reduction, efficiency of feed utilization reduction, anorexia, cough, expiratory dyspnea, diarrhea, though overall mortality rate is not high, can have a strong impact on the economic benefit on pig farm.At present, some new characteristics have appearred in prdc, the one, the pathogen that shows as mixed infection changes more to some extent, pathogen is that the infection of mycoplasma pneumoniae, reproductive and respiratory syndrome virus (PRRSV), 2-type PCV-II (PCV-2) etc. is main, again in conjunction with other bacterium secondary or mixed infection.The 2nd, the change of disease time, the pig that shows as wean each stage of back all can fall ill, promptly from weaning 2 weeks of back, until prdc can take place fattening period.This disease all can take place the pig of various kinds, all ages and classes and purposes, and classical PRDC betided for 18～20 ages in week, thus be called 18 age in week wall.China PRDC in the past in 2003 can betide the growth pig stage, i.e. in 12～15 ages in week, this moment, main pathogen was mycoplasma pneumoniae, PRRSV and swine influenza virus.And present morbidity can begin to take place (promptly before and after 40～50 ages in days) 2～3 weeks after wean, also can betide in 2 weeks after changeing group.Key issue is the infection time of PRRSV, and the time of stress reaction generation.Betide before and after the wean if PRRSV infects, then the disease time of PRDC can be after wean 2～3 weeks; If PRRSV infects the later stage that betides the child care house, or after changeing the group, then PRDC can betide the early stage of growth phase.So different pig farm disease time differences, the order of severity of morbidity is different with loss.And stress reaction can significantly reduce the resistance of pig, and the generation of promote infecting can betide any stage, but modal be wean, change the group and mix the group stress, resistance infects when descending, and process incubation period different in size just can show symptom.The clinical symptoms of PRDC is relevant with the main pathogen of infection, if based on mycoplasma pneumoniae, then The main symptoms is for a long time cough, then causes symptom based on accelerated breathing, expiratory dyspnea, diarrhea based on the infection of PRRSV.If based on influenza infection, the morbidity of group pig symptoms such as breathing is the devil, heating, diarrhea occur suddenly entirely.But present breathing problem generally is mixed infection, and it is main being difficult to any cause of disease of difference sometimes.Main pathogens as the Taiwan weanling pig respiratory diseases that a pig farm takes place at the year ends 2003 is influenza virus, PCV-2 and mycoplasma pneumoniae.Persistent infection is the EPDML key character of PRRSV, and PRRSV can exist for a long time in infected pigs's body.Equally, the disease that other type is propagated by respiratory tract, alimentary canal is also deep is perplexing the various places raiser, and respiratory tract and disease of digestive tract threaten the pig industry of China day by day, to the stage that must solve.
Summary of the invention
The present invention is a raw material with natural willow, processing through science, comprehensive potent trophism can be provided for nerve, the immune system of animal, fast quick-recovery and enhancing animal immune system function, the mucus secretory volume of increase mucous membrane tissue strengthens the ability that mucous membrane of animal is secreted multiple IG antibody, strengthen all kinds of activity of immune cells, repair the mucous membrane tissue structure of damaging, thereby resist the invasion of PRRSV virus efficiently, thereby reduce the incidence of disease of livestock and poultry respiratory and disease of digestive tract.
Technical scheme of the present invention to achieve these goals is to adopt following means to realize:
A kind of willow extract feed additive is carried through twice water by willow and to be formed with appropriate carriers after adding spray drying treatment.
Described carrier is preferably at least a in attapulgite, silica, pine needle meal and the maltodextrin.
The present invention also provides a kind of preparation method of willow extract feed additive, and concrete steps are as follows:
Respectively with poplar flower and skin brachymemma, clean, choose clean;
Raw material is packed in the multi-function extractor, through 6 times of water gagings, boiled 1 hour, steam pressure is that 1Mpa handles, and filters, and obtains first filtrate and filter residue;
Filter residue boiled 1 hour once more through 6 times of water gagings, and steam pressure is that 1Mpa handles, and filters, and gets second filtrate and filter residue respectively; Filter residue discards;
First filtrate, second filtrate mixed and be concentrated into D=1.19-1.2 promptly get extract medicinal extract;
The medicinal extract container of packing into refrigerates in 1-4 ℃ and preserves down;
Medicinal extract enters spray dryer, 180 ℃ of EATs, and 70 ℃ of leaving air temps promptly get a kind of willow extract formulation dry powder.
Monomer dry powder promptly gets a kind of willow extract feed additive after mixing with the carrier that is fit to.
The present invention has following remarkable advantages and beneficial effect:
1) anti-inflammation, control animal breath road and disease of digestive tract;
2) the harmful bacterium of absorption, virus strengthen body's immunity, promote growth;
3) palatability is strong, improves feed intake;
4) natural, noresidue, have no drug resistance, have no side effect.
The specific embodiment
Below in conjunction with specific embodiment the present invention is illustrated:
A kind of willow extract feed additive is made up of following parts by weight prescription: poplar flower extract 2-4 part; Carrier 3-6 part.
