A method for preserving animal feed involves treating the animal feed with an inorganic acid having a pKa from 1.0 to 5.0 to reduce the pH of the animal feed to less than 4.5. Sodium bisulfate is a preferred inorganic acid. Preferably, the acid is substantially completely dissolved and is substantially uniformly distributed throughout the animal feed. In a preferred method, the animal feed is treated by mixing the animal feed with a dry acid and applying steam to the mixture. An animal feed composition contains a feed grain and an inorganic acid having a pKa from 1.0 to 5.0, where the acid is present in an amount sufficient to reduce the pH of the animal feed to less than 4.5.
