Antimicrobial formulation
An anti-microbial composition for treating animal feed, comprising: 1 to 90 wt. %, based on the total weight, of a C 1 to C 24 organic acid, 1 to 90 wt. %, based on the total weight, of trans-2-hexenal provided it constitutes at least 5 wt. % of the organic acid and aldehyde mixture, 0 to 50 wt. % based on the total weight of terpenes, 0 to 20 wt. % based on the total weight of a surfactant, and water.
1. A method of treating an animal feed that is a solid, said method comprising mixing the animal feed with an effective amount of an anti-salmonella composition that is not compositionally modified before or while being mixed with the animal feed, wherein the anti-salmonella composition comprises:
pelargonic acid at an amount in a range of about 5 wt % to about 10 wt % of the composition;
propionic acid at an amount in a range about 65 wt % to about 75 wt % of the composition; and
trans-2-hexenal at an amount in a range of about 15 wt % to about 25 wt % of the composition;
thereby resulting in a treated animal feed suitable for consumption by an animal for which the animal feed is appropriate, wherein the treated animal feed comprises the animal feed and the effective amount of the anti-salmonella composition.
2. The method of claim 1 , wherein the amount of pelargonic acid is about 5 wt %, the amount of propionic acid is about 75 wt %, and the amount of trans-2-hexenal is about 20 wt. %.
3. The method of claim 1 , wherein the animal feed is mixed with the anti-salmonella composition via spraying and the effective amount of the anti-salmonella composition corresponds to an application rate in a range of about 1 kg to about 3 kg of the anti-salmonella composition per metric ton of the animal feed.
