The detoxicating mycotoxin agent of a kind of pig feed
Technical field
The present invention relates to the detoxicating mycotoxin agent of a kind of pig feed.Additive of the present invention can effectively be removed mycotoxin to the harm of growth of animal performance, production performance and health status, belongs to the feed additive field that ensures feed safety.
Background technology
Mycotoxin is the poisonous secondary metabolite that some mould produces in the growth and breeding process on cereal or feed, has had up to now 300 kinds of mycotoxins of surpassing to be isolated and identified out.During herding is produced, common and mycotoxin that can directly affect growth of animal production performance and health status is mainly produced by four kinds of mould Pseudomonas: Eurotium (mainly secreting aflatoxin, ochratoxin etc.), Penicillium (mainly secreting the mould toxin of tangerine), Claviceps (mainly secreting ergotoxin), fusobacterium (mainly secreting vomitoxin, zearalenone, T-2 toxin, fumonism etc.).Mycotoxin can cause that organa parenchymatosum's damage (liver, kidney), immunosupress appear in pig, (sow false heat or oestrous cycle extend breeding difficulty, after ablactation, insemination of sows returns the rising of feelings rate, Repeat breeding or pseudopregnancy occurs, in-pig miscarriage or product stillborn foetus, milking sow lactation amount reduces or agalasisa, the boar sexual desire is poor, degradation under sperm motility), feed intake decline, the stagnation of growing, become thin, the illness such as feed conversion rate reduction.
Cereal (feedstuff) thus field growing, results, storage, process and the process of feeding in all might fungal infection cause the generation of mycotoxin.The harm of mycotoxins in feed has been serious problems of the global aquaculture of impact.According to FAO (Food and Agriculture Organization of the United Nation) investigation, the whole world is accounted for 25% left and right of its total amount every year by the cereal of mould contamination, oilseed and feed.2006~2007 years, Ao Teqi company found more than 800 sample detection that Asia gathers, and zearalenone, the deoxidation melon of raw food, feed etc. withers the positive rate of reaping hook alcohol, fumonism, aflatoxin all more than 90%.Ao Zhi has just waited 225 sample detection has been found; corn, complete feed, protein feed, corn byproducts (corn germ cake, corn protein powder, maize alcohol stillage etc.) milk cow mixed fodder; 6 kinds of mycotoxin recall rate average out tos 93.2% of ensilage; the highest vomitoxin reaches 99.1%; exceeding standard rate average out to 29.6%, the highest vomitoxin that exceeds standard reaches 53.5%.The Ministry of Agriculture was to coming from 32 corn samples in the whole nation in 2009,46 protein raw materials samples, 23 complete feed samples detect discovery, aspergillus flavus toxin pollutes the most serious, zearalenone the second, T-2 toxin, vomitoxin, FT, ochratoxin pollute ubiquity.All samples all detects aspergillus flavus toxin and vomitoxin, 89% corn sample is the zeranol positive reaction, and usually by mycotoxin contamination more than three kinds or three kinds, 80% dregs of beans contains aspergillus flavus toxin, T-2 toxin and three kinds of toxin of zearalenone simultaneously.2011, hundred Ao Ming companies are to having carried out the detection of 13854 samples time from all over the world 4327 samples, each mycotoxin positive rate is respectively: aflatoxin 27%, zearalenone 40%, vomitoxin 59%, FT 51%, ochratoxin 27%.
By rejecting mouldy or damaged seed, slough and contain the more outer covering of a kernel of toxin or plumule, clear water elutriation, the methods such as sunlight insolation, radiation, heating, can reduce the toxicity of mould quantity and reduction mycotoxin, but the method is difficult to thoroughly eliminate the toxin that mould produces.Multiple natural or synthetic mycotoxin scavenger had appearred on market in recent years, with removing mould and the mycotoxin that has polluted in feed and raw material, by its mode of action, can be divided into following a few class: physics detoxicity method, chemical detoxication method, biological detoxication method etc. are several.
(1) physics detoxification: its principle is can the absorbing mycotoxin material by adding in feed, and toxin is not absorbed by animals through animal intestinal the time, directly excretes.Mold toxin sorbent commonly used has, natural aluminosilicate (as zeolite, montmorillonite, diatomite, kaolin etc.), mannan-oligosaccharides etc.
Natural aluminosilicate to the adsorption capacity of mycotoxin not only with adsorbent relevant with the size of total charge dosage, charge distribution, hole and available surface area (specific area), and be decided by the physical features such as polarity, solubility, molecular size, molecular shape, CHARGE DISTRIBUTION of the lps molecule that is adsorbed.Natural aluminosilicate has advantages of larger specific area, but simultaneously also has certain defective: show as that absorption affinity is little and efficient is low; Must heavy dose of (1-3%) add ability effectively in use, and only for aflatoxin and ergotin, certain absorption affinity be arranged; To vomitoxin, the T-2 toxin, zearalenone, ochratoxin A, snakelike verticillium toxin, Festuca Arundinacea toxin etc. does not have suction-operated; Nutriment in feed also there is suction-operated, thereby reduces feed nutrition concentration; Use the feed of this kind adsorbent to exist by the risk of dioxin (dioxins) and heavy metal pollution.
Mannan-oligosaccharides prevent the animal mycotoxin poisoning aspect,, effect few with its addition is significantly and cause people's extensive attention in conjunction with characteristics such as the mycotoxin kind are wide.Present studies show that in a large number, mannan-oligosaccharides can with many mycotoxin combinations, eliminate mould to the impact of body.The simulation broiler chicken alimentary canal in vitro tests such as Raju show, mannan-oligosaccharides is respectively 82.5%, 51.6% and 26.4% to AFB1, FT toxin, ochratoxin in conjunction with rate.The in vitro test of Trenholm etc. shows, under the pH=4.0 condition, mannan-oligosaccharides reaches respectively 80%, 95%, 77%, 59% and 12% to the knot platform rate of zearalenone, aflatoxin, zearalenone, fumonisin and vomitoxin.Mannan-oligosaccharides is the oligosaccharide kind material that mainly extracts from the yeast cell wall skin, and therefore obtaining mannan-oligosaccharides needs tightly high fractionation technique accurately.Domestic shortage is with the yeast cell wall demixing technology, just simply yeast cell wall integral body is pulverized and used as immunostimulant and mould adsorbant function product, cause mannan-oligosaccharides active ingredient dosage on the low side and make the absorbing mycotoxin effect differ greatly with the result of document report, limited greatly promoting the use of in market.
(2) chemical detoxication.Some mycotoxin can be destroyed degraded by the chemicals of part, with the mouldy seed of soda lye wash, soaks moldy feed with ammoniacal liquor or copper-bath as common.But there is following drawback in the method: different chemical substances often only effectively can not be degraded to other toxin to certain toxin, and the chemical substance of use is residual and produce new poisonous and harmful effect in feed.(3) biological detoxication.Mainly contain enzymatic isolation method and microbe fermentation method, enzymatic isolation method is to make the functional group of mycotoxin/toxicity inactivation by enzyme digestion reaction.The limiting factor that the method is subject to has, and in essence, enzyme is also protein, and its vigor can be subjected to pH, temperature and be subjected to the impact of matter (mycotoxin).The defective of the method is: feed may not necessarily provide the environment that is fit to this kind enzyme; Enzyme is very high to the narrow spectrum degree of the selection that is subjected to matter, be critical sometimes, so these class methods equally only has certain effect to certain toxin; Secondary species after enzymolysis might be toxic; Enzyme is thermo-labile, at the easy inactivation of feed process.The effect of microbe fermentation method is slow, is not suitable for feed factory and plant.Therefore, use that biological detoxication method cost is higher and effect is unstable, thus in production practices still difficulty apply.
(4) normal flora and Chinese herbal medicine detoxicity method.In recent years, having and add lactic acid bacteria with the report that removes aflatoxin in feed, is mainly by keeping the gut flora balance, strengthening the immunity of body to alleviate the harm of toxin.The method contratoxin does not have specificity, only rests on the experimental stage, differs greatly from practical application.
Since 2007, detoxicating mycotoxin agent commodity all emerge in an endless stream every year, but annual feed mould Positive rate, the poisoning incidence of disease of livestock and poultry mycotoxin remain high, and from the angle of actual production practice, existing detoxicating mycotoxin agent effect on market is undesirable.
