New aqueous concentrates adapted for dilution to form use compositions, and methods of preventing or treating hoof diseases with these use compositions are provided. The compositions and concentrates comprise (and preferably consist essentially of) a quaternary ammonium compound, an acid, and a surfactant. Preferred quaternary ammonium compounds include those selected from the group consisting of alkyl dimethyl benzyl ammonium salts, alkyl dimethyl ethyl benzyl ammonium salts, dialkyl dimethyl ammonium salts, dialkyl methyl benzyl ammonium salts, and mixtures thereof. The inventive methods comprise diluting the concentrate to form a use composition and applying the use compositions to the affected areas by spraying, under a bandage, or in a footbath. The invention is particularly well-suited for treating papillomatous digital dermatitis. |
