    专利说明:

    The present invention relates to an additive for predominantly plant constituents, such as cereals, maize, grass, lucerne or the like, consisting of selenium-containing feedstuffs containing at least one inorganic mycotoxins detoxifying salt,
    Additives for animal feed are known and widely used for a wide variety of purposes, such as additives intended to discourage animal deficiencies during rearing, such as vitamin preparations or the like, as well as additives intended in particular to enhance performance and, finally, additives which are intended for the binding and / or rendering harmless of harmful substances, which are frequently present in feed occurrences, in particular of feed consisting predominantly of plants or plant constituents, such as mycotoxins or the like.
    For the detoxification of feed for livestock are here on the one hand a variety of substances on which the on or in from plants or plant components, such as cereals, corn, grass, lucerne or the like. Existing feed existing mycotoxins are adsorbed or deposited, known, wherein Here bentonites or zeolites are used in particular, which due to the large number of layers, channels and pores formed therein have an extremely large, internal surface on which large amounts of harmful substances can be adsorbed.
    Finally, in recent years, it has been possible to find specific microorganisms capable of enzymatically degrading individual mycotoxins, such as deoxynivalenol.
    Another way to remove mycotoxins from feed is the use of yeasts or yeast components, such as yeast cell walls, to which mycotoxins can be attached or bound and thus rendered harmless. - 2 - ·· • »
    In addition to the adsorption or addition of mycotoxins to surfaces and the enzymatic degradation of mycotoxins, however, it is also possible to detoxify mycotoxins chemically and / or enzymatically by degrading or converting them into non-toxic cleavage or reaction products.
    In this context, it can be seen from DE 10 2008 002 013 A1, for example, that mycotoxin-contaminated crop harvest products can be detoxified by containing a preparation containing at least one sulfur dioxide-derived oxygen acid or salts thereof and an amine of the formula NH 2 R or its Salts of the formula [NH3-R] + X " be used. By using such a mixture it is possible to break down mycotoxins, in particular trichothecenes and / or zearalenones, and thus make them harmless.
    It has proved to be disadvantageous in use that combinations of a monosubstituted amine compound and an oxygen acid derived from sulfur dioxide or their salts have to be used in order to reduce the mycotoxins present or present on the feed, in particular the trichothecenes, aflatoxins and / or zearalenones , which makes the composition of the feed or the additive relatively complex.
    A disadvantage of the known methods for detoxifying feed consisting predominantly of plants or plant constituents, moreover, is the fact that each detoxifying individual substance known hitherto or each insertable microorganism detoxifies only one or at most two different mycotoxin families was able to bind and therefore only one. very specific use of the substances or microorganisms to be used was possible.
    The present invention now aims to provide an additive for feed consisting predominantly of plants or plant components, such as cereals, maize, grass, lucerne or the like, with which it is possible to obtain 3 ···· * 9, to simultaneously degrade or immobilize a large number of such harmful constituents present in animal feed, in particular mycotoxins.
    According to the invention, the additive for a feed consisting predominantly of plants or plant components is essentially characterized in that the inorganic mycotoxins detoxifying salt is an alkali metal or alkaline earth metal sulfite and / or a selenium-containing salt. By the additive is constructed so that inorganic or mycotoxins detoxifying salt is an alkali or alkaline earth metal sulfite is used and / or a selenium-containing salt, it is possible on the one hand, not only the known, germicidal effect of sulfite or analogous or similar selenium-containing Exploiting salts, but it has surprisingly been found that the use of only small amounts of alkali and or alkaline earth metal sulfites particularly beneficial effect on the degradation of mycotoxins, especially mycotoxins from the group of trichothecenes or zearalenones. It is thus with a relatively small amount of added, inorganic alkali or alkaline earth metal sulfite for the degradation of relatively large amounts of mycotoxins found the way, so that not only an extremely efficient acting additive, which can be used directly in solid form, in addition Is made available, but also the use of the additive in any case for the subsequent consumption harmless amounts seems sufficient. Improved results are achieved when using selenium-containing salts, it being assumed that in the present case a catalytic effect is caused by the selenium content of the salts or compounds used.
    According to a preferred development of the additive is formed so that a sodium, potassium, magnesium and / or calcium sulfide is included. The use of any of the above-mentioned sulfites is not only economically favorable, but these compounds are particularly preferred because of their relatively good solubility and workability. In addition, the preferred sulfites additionally act as reducing agents, so that optionally further harmful substances contained in the feed based on plants or plant components can be reduced directly to non-toxic substances.
    By, as corresponds to a preferred embodiment of the present invention, the inorganic mycotoxins de-toxif.izierende sulfite in an amount of 10% to 100% contained in the additive or the additive consists of the same, and it is sufficient, mycotoxins and in particular Deoxynivalenol rapidly and reliably converted into deoxynivalenol sulfonate, which is a non-toxic metabolite, or to detoxify zearalenone.
    According to a preferred embodiment of the invention, the additive is formed so that in addition to or instead of the alkali and / or alkaline earth metal sulfite as selenium-containing salt at least one sodium, potassium, magnesium, calcium selenite are included in the additive. By containing as selenium-containing salt at least one sodium, potassium, magnesium, and calcium selenite in the additive, it is possible on the one hand, safely and reliably degrade the mycotoxins in their non-toxic metabolites and on the other hand at the same time the important trace element selenium in sufficient quantities To provide an overall performance increase in the animals fed with it, which goes beyond the cumulative effect of a sole administration of selenium or a detoxification of mycotoxins, can be achieved.
    By additionally containing a further selenium-containing compound, such as a selenium yeast, in the additive, as is the case with a preferred development of the invention, it is possible, in particular in addition to the advantageous effects of selenium in the additive, to provide a yeast which mycotoxins, such as eg zearalenone adsor- 5 - * * · ··· «« > So that even more complete detoxification of the feed treated with the additive can be achieved. *** "
    According to a preferred embodiment of the present invention, the additive is formed so that selenium is present in a finished feed in a concentration of at most 0.5 ppm, preferably at most 0.2 ppm. By setting the selenium concentration to a maximum of 0.5 ppm, it is ensured that on the one hand the trace element selenium is present in sufficient quantities, and on the other hand that excessively large amounts, which in turn can have adverse effects, can be avoided with certainty. For this purpose, for example, the additive is formed so that mixtures of alkali or alkaline earth metal sulfites and, for example, a selenium yeast are used, whereby an additional, preferred effect is achieved in that the yeast contained in the additive in a conventional manner optionally further contained in the feed Bind mycotoxins and thus can render harmless. For a further improvement of the addition or adsorption of mycotoxins contained in feeds or to additionally contribute useful or the performance of animals enhancing substances to the feed additive, the additive according to the invention is further developed such that in addition a solid carrier selected from one or more substance (s), such as a naturally occurring or modified silicate mineral, such as smectite, montmorillonite, saponite, kaolinite, vermiculite, illite, sepiolite, attapulgite, zeolite, clinoptilolite and / or silicate-mineral containing compounds, such as bentonite, diatomaceous earth and / or biopolymers , such as chitosan or mannanoligosaccharides. are included. In this case, by carefully selecting an inorganic carrier based on silicate, it is possible, surprisingly, to safely and reliably adsorb the reaction products of deoxynivalenol formed by the addition of the alkali metal or alkaline earth metal sulfites, and by selecting optionally utilizable as

    Carrier-usable biopolymers to achieve a still further increase in performance of animals to which the additive was fed according to the present invention.
    By, as in a preferred embodiment of the present invention, the additive is formed so that the solid carrier is contained in an amount of 90% to 5% of the additive, it is possible to ensure any adaptation of the additive to the intended purposes, such as in cases in which in addition to an effective decontamination of mycotoxins or a degradation of the same, a specific, targeted nutrient content to be made available to stop.
    In addition, in order to certainly certainly prevent any contamination with zearale-non, the feed supplemented with the additive according to the present invention, the additive is preferably developed in such a way that additionally selenium-free yeasts and / or yeast cell walls or yeast cell wall constituents are contained. By additionally containing selenium-free yeasts and / or yeast cell walls or yeast cell wall components, not only a safe adsorption of zearalones succeeds but surprisingly, in addition to the above-described synergistic effect, a binding of the formed degradation products, in particular the deoxynivalenol sulfonates, is achieved a further increase in performance of the animals supplied with the feed additive according to the invention can be observed.
    It has been found to be favorable that, as corresponds to a preferred embodiment of the invention, the selenium-free yeasts and / or yeast cell walls or yeast cell wall components are contained in an amount of 80% to 10%, so that the adsorption of deoxynivalenol formed as reaction products Sulfonates can be ensured. Surprisingly, it has been found that the invention is preferably developed in such a way that the additive as inorganic mycotoxins detoxifying salt sodium sulfite as well as 7 *
    addition catalytic amounts, in particular a concentration of 2 or 20 wt .-% of a selenium yeast, the effect of the inorganic mycotoxins detoxifying salt can be significantly enhanced, which is attributed to a catalytic effect of added selenium yeast, as in a final feed after degradation of all Mycotoxins, an almost unchanged concentration of selenium can still be detected.
    A particularly complete removal of mycotoxins, such as deoxynivalenol, aflatoxin and zearalenone in feeds succeeds when the additive is preferably designed so that it contains 25 to 93 wt .-% sodium sulfite, 2 to 20 wt .-% selenium yeast and 5 to 73 Wt .-% bentonite as a carrier. To ensure that a uniform detoxification of all mycotoxins possibly contained in a feedstuff succeeds, the additive is preferably developed in such a way that it is used as a homogeneous, finely ground powder. When such a finely ground powder is mixed with the feed, it is ensured that it evenly degrades the existing mycotoxins throughout the feed, either by reduction into harmless constituents, or adsorbs them to the surface of the other adsorbents contained in the additive, and thus no longer can be metabolized. Surprisingly, it has been shown that, as corresponds to a preferred embodiment of the invention, the feed additive can be used to increase the performance of livestock. Here, the increase in performance is attributed, on the one hand, to the detoxification or adsorption of the mycotoxins present on the feed, and, on the other hand, to the fact that the optionally usable substances, such as yeasts and the like, which are additionally present in the feed additive are also able to contribute to an increase in performance.

    The invention is subsequently carried out on the basis of degradation experiments with various alkali or Erdalkalimetallsufiten and optionally selenium yeast on kontox with deoxynivalenol corn.
    In these maize meal was mixed with different natural water contents and different starting concentrations of deoxynivalenol (DON) and acetyldeoxynivalenol (AcDON) with different concentrations of alkali or alkaline earth metal sulfite.
    The results are shown in the following experiments and figures. In these shows

    Corn meal with 6% water content, neutral pH, 23.0 ppm DON and 3.1 ppm AcDON as initial concentration and 1% Na sulfite were measured twice each at different temperatures after an incubation period of 24 h.

Visible that at room temperature (25 ° C) within 24 h, a reduction in the initial concentration of DON or AcDON by 64% and 67% can be achieved, whereas when performing the same test at 60 ° C, essentially no change in the reduction can be seen relative to room temperature. Specifically, reductions of 63 Ir and 75% of the starting toxins were achieved in two repetitions.

    An analogous experiment (two repetitions) was carried out with the addition of 1% sodium sulfite for a longer incubation time, as shown in Table 2, after a 48 hour incubation at room temperature (25 ° C) a reduction of 54% or 61%, whereas at elevated temperatures of 60 ° C a reduction of the starting toxin concentration of up to 83% can be achieved.

    In a further experiment, corn meal with 13.5% water content and neutral pH and a starting concentration of 14.8 ppm DON was each subjected twice to a sodium sulfite treatment with 0.2% sodium sulfite to show that within the first 24 h The reduction of 46% could be achieved and that with prolonged storage of the maize meal under constant conditions (such as temperature, relative humidity) at 25 ° C for up to 7 days, the concentration of DON is reduced until about 76% of the starting toxin concentration has been reduced. 10% ** * ··· ·· («* ·· ·

    Finally, corn meal with 13.5% water content and a starting concentration of 23.0 ppm DON was subjected to two repetitions of treatment with 0.5% sodium sulfite and selenium yeast, the selenium yeast containing 2000 ppm selenium. It can be seen from Table 5 that immediately after mixing the maize meal with the feed additive, between 67% and 71% of the initial concentration of DON contained in the feed set was reduced or degraded and thereafter the value was maintained substantially constant for 24 hours. from which a synergistic effect between the alkali metal sulfite and the selenium yeast or a catalytic effect of the selenium yeast can clearly be derived.

    Finally, in a storage experiment, piglet feed containing 0.1% sodium sulfite or 0.1% magnesium sulfite was investigated with regard to the reduction of the mycotoxin concentration. As can be seen from Table 6, with sodium sulfite, significantly better results were obtained, both in terms of deoxynivalenol (DON) and Ac-DON and zearale-non (ZON) compared to treatment be achieved with magnesium sulphite.

    In summary, it should be noted that by adding small amounts of inorganic alkali metal or alkaline earth metal and optionally of selenium-containing substances such as selenium a significant reduction of mycotoxin concentration in feed can be achieved without further additives or artificial moisture must be added.
    Trial 2
    In an in vitro experiment, attempts were made to decontaminate deoxynivalenol contaminated feed samples with different additives or mixtures of additives according to the invention.
    Specifically, 10 g of a feed sample loaded with deoxynivalenol containing corn grist was placed in a sample tube and admixed with an aqueous 0.05% sodium sulfite solution having a pH of 4.5. In Fig. 1 it can be seen that after 1 h about 13% of the contained deoxynivalenol were detoxified and after a time of more than 2 h about 16% of the same. When a sample having the same concentration of deoxynivalenol is treated with a slurry containing 0.05% sodium sulfite and 0.05% by weight of a selenium yeast, about 20% of the deoxynivalenol is degraded after 1 h and greater than about 2 h 40%. Analogous experiments were carried out in each case with the addition of 0.05% sodium sulfite and sodium selenite, sodium sulfite and EDTA, sodium sulfite and yeast, sodium sulfite and chitosan, calcium sulfite, magnesium sulfite. The best results are in addition to the combination of sodium sulfite and selenium yeast with sodium sulfite and - 12

    Magnesiumsulfit achieved in which already after 1 h, a reduction of 40% of the deoxynivalenol contained in the sample can be observed.
    An analogous experiment with equal concentrations of deoxy-nivalenol, sodium sulfite and the other additives listed was carried out at a pH of 8, which shows that especially when the additive is added in a neutral to slightly basic medium, an extremely rapid degradation the deoxynivalenol can be observed, surprisingly in the basic medium, the best results can be achieved with sodium sulfite and ETDA or sodium sulfite and sodium selenite, in which, as shown in Fig. 2, with sodium sulfite and ED TA a 100% chemical conversion of deoxynivalenol can be achieved and with sodium sulfite and sodium selenite after 1 h already more than 90% of deoxynivalenol are converted.
    From Fig. 1 and 2 thus shows that, as corresponds to a preferred embodiment of the present invention, the feed additive can be mixed directly into the feed and immediately, without such a staggered feed from an animal must be taken or before it is taken up, a detoxification of the feed takes place.
    Trial 3
    This experiment shows a comparison of the degradability between sodium sulfite and the sodium metabisulfite already used in the prior art on samples containing various deoxynivalenol.
    From Figs. 3 and 4, which show the effect of sodium metabisulfite (SBS) after 1 h and 2 h, respectively, on the most varied samples, it is clearly evident that sodium metabisulfite has an effect only in phosphate-buffered samples within 1 h, while Sodium acetate, wheat extract and phosphate buffer containing at least 2 h of remarkable amounts of deoxynivale - 13
    nols to DONS 3, the structure of which is currently unknown.
    When analogous samples are used but 0.5% of sodium sulfite is used instead of 0.5% of sodium metabisulfite, as shown in FIGS. 5 and 6, it is particularly evident in the wheat extract and phosphate-containing samples after 1 h, substantial amounts of DONS3 have already formed, just as in the samples containing tap water not insignificant amounts of degradation products, namely DONS1 and DONS2, which are also no longer harmful, have emerged. When this experiment is run for a period of 2 hours, it can be seen that sodium sulfite is able to break down the total deoxynivalenol content into harmless metabolites, particularly DONS3 in wheat extract-containing samples.
    Specifically, it is known that the degradation products DONS1 and D0NS2 represent deoxynivalenol sulfonates and ketals, respectively, while DONS3 as well as D0NS2 probably represents a C-15 ketal, but its structure is not fully understood at the present time.
    In summary, it can be seen that, compared to the known sodium metabisulfite, sodium sulfite degrades deoxynivalenol much more rapidly and completely, in particular converting into three metabolites, whereas when degraded with sodium metabisulfite, only one metabolite, DONS3, can be found, if at all.
    Trial 4
    In feeding trials, the effect of a sulphite-containing feed additive on feed contaminated with mycotoxins in the feeding of piglets was investigated.
    For this purpose, approximately 20% of the maize in the experimental groups was replaced by highly contaminated maize. 150 piglets (approximately 4 weeks old, average weight 8.33 kg) were individually weighed and divided into four groups of comparable average weight divided into 14 ····. 30 piglets, whose individual weight deviates too much from the average, were isolated.
