Definitions
- the present invention pertains to feed additives for animal feed, in particular feed preservatives.
- Feed additives for animal feed are well known. Such feed additives may serve to improve the gut health of animals, especially livestock, or to improve the general health of the animals. Also feed additives are known to preserve animal feed, in particular against bacterial infestation and/or fungal infestation. A commonly used ingredient in such preserving feed additives is propionic acid and salts thereof. Propionic acid may relatively effectively reduce mold formation on animal feed. Under certain conditions, e.g. at higher temperatures and/or more moist conditions, the effectiveness of propionic acid may not be sufficient. Moreover, under such conditions the stability of the feed additive, and the diluted feed additive (with water) before it is applied onto the animal feed may be low, which in turn renders the feed additive to be less effective against molds. The object of the invention to provide novel feed additives.
- the present invention pertains to a feed additive comprising an emulsifier, propionic acid and/or salt thereof and at least one fatty acid having 6 to 12 carbon atoms, wherein the weight ratio of propionic acid and fatty acid is at least 2 and at most 25 and the amount of ammonium formate is less than 0.5 wt%.
- the feed additive of the invention was shown to have a better antifungal efficacy against molds, especially molds that form on animal feed upon storage.
- the fatty acids generally are more efficacious against mold than propionic acid and/or its salts, i.e. these fatty acids have a lower minimum inhibitory concentration (MIC) value for various molds than propionic acid and/or its salts.
- MIC minimum inhibitory concentration
- the feed additive of the invention is effective against xerophilic molds, i.e. molds that also grow under water-poor or water-free environments such as Aspergillus chevalieri or Penicillium lanosocoeruleum.
- the combination of propionic acid and the fatty acid of the invention exhibits a synergistic antifungal efficacy against molds when compared to propionic acid and fatty acid per se, i.e. the actual efficacy of the combination is more than the sum of the individual efficacies of the individual components.
- the presence of the fatty acids, and particularly when the amount of the fatty acid of the invention is at least 2.5 weight percent (wt%), increases the stability of the feed additive per se, and upon dilution with water before being applied to the animal feed.
- a further advantage is that animal feeds will contain less to no mycotoxins originating from molds such as
- Aspergillus flavus and Aspergillus parasiticus are also the shelf life of animal feed.
- Further advantages of the feed additive of the invention are its ability to inhibit bacterial growth, to improve the gut health, improve epithelial integrity and improve the palatability of the animal feed.
- the feed additive of the invention comprises propionic acid and/or salt thereof.
- the feed additive may comprise propionic acid alone, a salt of propionic acid alone or a combination of propionic acid and a salt of propionic acid.

- the invention further pertains to the use of a feed additive comprising an emulsifier, propionic acid and/or salt thereof and at least one fatty acid having 6 to 12 carbon atoms, wherein the weight ratio of propionic acid and fatty acid is at most 25 and the amount of ammonium formate is less than 0.5 wt% in drinking water for animals, in particular livestock.
- the invention is exemplified in the following Examples.
- Example 1 Synergistic effect of propionic acid with MCFA towards fungi
- test compound solutions prepared in ME20S medium were gently added to the standing cultures and mixed carefully. This culture was incubated for 30 min at room temperature, and biofilm was loosened by means of a pipetting tip and 10 pL culture was added to 90 pL demi water containing 4 pM TOTO-1
- Micrographs were taken with the Axiocam software (Zeiss, Oberkochen, Germany). The total time of exposition to ingredients was 30 min. and germ tubes in diluted solutions were counted afterwards in a time window of 30 min starting 15 min after the beginning of staining.
- Aspergillus chevalieri showed a significantly higher percentage of TOTO-1 stained cells when incubated with a combination of propionic acid and NFU and MCFA + pol80, than when incubated with the sole ingredients (see Table 1). Especially at the higher concentrations, 0.4 - 0.2 % (v/v), the synergistic effect of these ingredients is clearly evident.
- the antifungal activity of compounds was determined using a MIC (minimum inhibitory concentration) assay in microtiter plate format.
- A. was grown for 10 days at 25°C on DG18 (Dichloran Glycerol Agar) supplemented with 100 mg/I CAM (Chloramphenicol) plates (pH 5.6).
- the fungal spores were harvested by adding ⁇ 10-13 ml sterile ice-cold ACES-Buffer (N-(2-Acetamido)-2-aminoethanesulfonic acid)
- spores were added into malt extract broth supplemented with 10 % (w/v) sucrose and 100 mg/L CAM. A concentration range of test compounds was used to determine the MIC value at which no fungal growth was observed. The plates were incubated for 6 days at 25 °C.
- the antifungal activity was determined of mixtures with varying ratio of propionic acid and MCFA.
- lowering the MCFA concentration to 0 % significantly reduced the antifungal activity.
- the stability of the premixtures was tested under conditions that can mimic customer storage conditions of the product.
- One big issue for customers especially in the tropical areas is the instability of antifungal solution in a diluted form (7 or 10 volume percentage in water) during storage.
- An unstable diluted premix shows a visible phase separation of the fatty acids (at the top) and water fraction, independent of the presence of an emulsifier.
- Our results showed that a good stability at room and higher temperatures of the diluted premixtures was achieved when the MCFA concentration was increased to 4 % in the premixture. Lowering of the MCFA concentration to 1 % and lower resulted in a stable diluted premix as well.
