Definitions
- the invention is directed to compositions and their use as feed additives to reduce mycotoxin contamination, preferably in animal feed.
- Mycotoxins are metabolites produced by fungi that are toxic to humans and/or animals. These fungi occur on natural materials such as grains and plants, where the mycotoxins are then formed. These mycotoxins are fairly resistant to all kinds of treatments and are, in addition, difficult to detect. As a result, fungi infested plant material acts as carrier for mycotoxins, allowing them to enter the animal food chain through the feed produced thereof, where they can cause discomfort and disease. The physical effects of mycotoxins differ from reduced food intake and poor food conversion to animal disease. The observed symptoms may also vary from animal to animal.
- Acute mycotoxicosis is often recognizable, but chronic mycotoxicosis takes its toll as it has an impact on animal performance and a reduction in immunity with all the known economic consequences. Liver damage and deterioration is one of the main characteristics of both acute and chronic mycotoxicosis, further compromising the animals' health.

Description
COMPOSITION FOR USE AS MYCOTOXIN BINDER IN ANIMALS
TECHNICAL FIELD The invention is directed to compositions and their use as feed additives to reduce mycotoxin contamination, preferably in animal feed.
BACKGROUND Mycotoxins are metabolites produced by fungi that are toxic to humans and/or animals. These fungi occur on natural materials such as grains and plants, where the mycotoxins are then formed. These mycotoxins are fairly resistant to all kinds of treatments and are, in addition, difficult to detect. As a result, fungi infested plant material acts as carrier for mycotoxins, allowing them to enter the animal food chain through the feed produced thereof, where they can cause discomfort and disease. The physical effects of mycotoxins differ from reduced food intake and poor food conversion to animal disease. The observed symptoms may also vary from animal to animal. Acute mycotoxicosis is often recognizable, but chronic mycotoxicosis takes its toll as it has an impact on animal performance and a reduction in immunity with all the known economic consequences. Liver damage and deterioration is one of the main characteristics of both acute and chronic mycotoxicosis, further compromising the animals' health.
Known state of the art solutions include the addition of (myco)toxin binders to the feed, in order to inactivate the mycotoxins before being taken in by the animal, or in the animal itself. EP 1 079 696 for instance discloses a composition comprising a clay mineral and a yeast component capable of binding mycotoxins into the feed. However, once the animal has ingested the toxins, there is also a need for a composition which helps to restrain the damage caused by the toxins, limiting their toxicity, thus assisting the animal to cope with the infection. WO 2 014 014 334 Al describes a food supplement for animals comprising a clay mineral, a yeast component and trace minerals. This food supplement, however, does not deal with the issues of mycotoxicity. RU 2 391 975 describes the use of high doses of betaine in feed containing mycotoxins to prevent mycotoxicosis in farm animals. The invention aims to provide a composition that is, on the one hand, functional as a toxin binder in feed while, on the other hand, protecting liver function in the animal, thereby having a double positive influence on the well-being of the animal and its performance.
SUMMARY OF THE INVENTION
The present invention provides a composition as stated in claim 1 for binding and inactivation of mycotoxins in animals, while protecting liver function. More specifically, the composition comprises (myco)toxin binders combined with betaine, thereby having a double positive influence on the well-being of the animal and its performance.
The current invention thereto aims to provide a composition comprising one or more mineral clays and a yeast component as (myco)toxin binders, acting both in the feed and in the animal. Betaine or a betaine derivative is included in the composition, which is functional in the animal as a liver detoxifying agent due to its involvement in methylation reactions and detoxification of homocysteine. In a second and third aspect, the present invention provides an animal feed comprising a composition as stated in claim 14 and a method as stated in claim 19.
The current invention thereto aims to provide an animal feed comprising the composition as stated above in combination with a preservative, and a method of providing this feed to animals.

The recitation of numerical ranges by endpoints includes all numbers and fractions subsumed within that range, as well as the recited endpoints.
The expression "% by weight" (weight percent), here and throughout the description unless otherwise defined, refers to the relative weight of the respective component based on the overall weight of the formulation.
For the purpose of the current invention, the term betaine is to be understood as referring to trimethylglycine. Trimethylglycine is an N-trimethylated amino acid. Betaine derivatives are to be understood as the products originated by conversion of betaine by strong acids to various salts. A betaine derivative can therefore be, but is not limited to, betaine hydrochloride which is yielded by conversion of betaine by hydrochloric acid.
The present invention provides a composition that can be used to reduce the negative effects of mycotoxins to the animals' health by, on the one hand, inactivating mycotoxins present in feed or in the animal itself and, on the other hand, by supporting the detoxification function of the liver in the animal.
In a first aspect, the invention provides a composition for binding and subsequent inactivation of mycotoxins while protecting liver function, comprising a yeast component, one or more mineral clays, characterized in that said composition further comprises betaine or a betaine derivative. Mineral clays are known as (myco)toxin binders, both in the feed as in the animal itself. The absorption of the toxins by the mineral clays prevents their uptake into the animals' blood stream. The combination of mineral clays with yeast cell wall extracts in animal feeds is known to further increase the mycotoxin binding effect. Binding of mycotoxins directly interferes with their toxicity mechanism.
The yeast component in the composition is preferably present in a concentration from 5% to 10% by weight and consists specifically of a yeast cell wall extract. In particular the cell wall is extracted from a yeast selected from the group of Saccharomyces, Candida, Kluyveromyces, Torulaspora or a combination thereof. More in particular, the yeast cell wall is extracted from a Saccharomyces cerevisiae yeast. More in particular, the yeast cell wall is hydrolysed prior to extraction and is, more specifically, composed of mannan-oligosaccharides.
The clay minerals in the composition are preferably present in a concentration from 40% to 80% by weight. In particular, one or more mineral clays are selected from the group consisting of zeolites, bentonites, aluminosilicates, magnesium aluminum silicates or mixtures thereof. In a preferred embodiment of the invention the mineral clay consists of a clinoptilolite.
The composition also aims at supporting the animals' endogenous defense mechanisms once mycotoxins have been ingested. After mycotoxin ingestion, the liver is burdened
with the inactivation and degradation of the mycotoxins. Accordingly, liver damage and deterioration is one of the main characteristics of both acute and chronic mycotoxicosis.
The composition thereto comprises betaine or a betaine derivative, which is involved in methylation reactions and in the detoxification of homocysteine. Betaine and betaine derivatives are used in this invention as detoxifying agents, supporting the detoxification functions of the liver, eventually contributing to the improvement of the animals' health.
Betaine is used in the liver as a methyl group donor. The liver is the major organ within which methylation reactions occur. Dietary intake of methyl donors like betaine could influence the methylation of DNA and histones, thereby altering the epigenetic regulation of gene expression. Many of the hepatic genes involved in pathways for the development of fatty liver, hepatic fibrosis, and hepatocarcinomas are epigenetically regulated. In addition, methylation reactions are also important for several metabolic processes such as the synthesis of creatine and carnitine.
The composition comprising a yeast component, one or more mineral clays, and betaine or a betaine derivative has a positive effect on animals' health which is larger than the effect expected of the individual components on the animals' health. Betaine or a betaine derivative is preferably present in the composition in a concentration from 0.001% to 5% by weight of the composition. When betaine or a betaine derivative is present in the composition in a concentration of at least 0.001% by weight of the composition, the synergetic effect of the composition is more pronounced. Above a betaine or a betaine derivative concentration of more than 5% by weight of the composition, the synergism between the different components of the composition was no longer observed. In a particularly preferred embodiment of the invention, the betaine derivative included in the composition is betaine hydrochloride.
The inventors of the present invention have found that a composition as described above is exceptionally suited to counteract the harmful effects of a broad range of toxins. The binding and inactivation of in particular Ochra toxin, zearalenones, deoxynivalenol (DON), fumonisins, aflatoxins, HT-2 toxins, T-2 toxins or enniatins contributes to the protection of the animals' health. In a preferred embodiment, the composition described in the present invention or a feed supplement comprising the composition described in the present invention comprises a preservative composed of a calcium, sodium or ammonium salt of propionate. This preservative prevents bacterial and fungal growth in the composition or in the animal
feed or drinking water upon addition of the composition. More in particular, the preservative is present in a concentration from between 5% to 10% by weight of the composition. In a second aspect, the composition of the present invention as described above has a remarkable positive effect on the animal when taken in and is thus well suited as a feed supplement or as addition to the animals' feed. Addition of the composition to feed directly or as (part of) a feed supplement therefore results in healthier animals. In one embodiment, the composition or supplement is a powder. In a different embodiment, the composition or supplement is a liquid. In yet another embodiment, the composition or additive is added to the animals' drinking water. In a preferred embodiment of the invention, the effective amount of the composition comprises from 0.5% to 1% by weight of the feed.
In particular the composition according to the present invention is suited for administration to animals selected from the group consisting of avian, bovine, porcine, equine, ovine, and caprine species In a third aspect, the present invention also describes a method of feeding animals with a feed supplemented with a feed supplement according to the present invention, wherein the animal obtains the feed additive in a content of between 5 g/kg and 10 g/kg bodyweight / day. In a specific embodiment of the invention, the composition is admixed with the animal feed prior to feeding. In an alternative embodiment, the composition is admixed with the animal's drinking water before it is provided to the animal.

Example 3: Study of the clinical effect of mycotoxins in pigs
50 pigs of either sex with average initial weight of 8.2 kg and average age 29 days were selected for the study. The animals were divided in 12 experimental groups. Half of the groups were fed with a feed that was contaminated with mycotoxins while the other half was fed with mycotoxin-free feed. Additionally, the feed of each group further differed in the presence or absence of a 0.5% feed supplement comprising 0%, 2.5% or 5% betaine hydrochloride (HCI). The feed supplement (see Table 2 for feed supplement composition) was admixed with the animal feed prior to feeding. The feed was administered 4 times per day and water was available ad libitum. The feed intake and weight gain was measured daily for 30 days. The Feed Conversion Rate (FCR) was calculated for each experimental group as the proportion of the feed intake (g) to the daily weight gain (g) and is used as a measure for pig health : the lower the FCR, the healthier the pigs.
Table 2: Feed supplement compositions used in example 3.
The results of the study are shown in Figure 3. A surprising effect was found when pigs were fed with mycotoxin contaminated feed that was provided with the feed supplement comprising betaine HCI. The FCR of pigs fed with the feed according to the current invention was much lower, indicating these pigs were much healthier due to the liver supporting function of betaine HCI. Notably, the positive effect on pig's health was larger than what could have been expected of the combination of feed supplement and betaine HCI based on the results of the feed supplement alone (0.5% supplement and 0% betaine HCI) or the betaine HCI alone (0% supplement and 0.0125% or 0.025% betaine HCI).
