A method of preserving fodder masses for animal feeding by applying an acid catalyzed coating liquid to the surfaces of the fodder masses. The coating liquid comprises a thermosetting monomer and a nutritive cross-linking agent, which is catalytically polymerized and cross-linked by a mineral acid to form a water insoluble solid barrier to the penetration of moisture, air, and other elements which can cause degradation of stored fodder. Suitable thermosetting monomers include: urea-formaldehyde resins, furfuryl alcohol, and their mixtures. Liquid carbohydrates derived from vegetable sources, particularly molasses, starch, and fermentation by-products, are effective cross-linking agents. Mineral acids found to be effective for the polymerization and cross-linking include: phosphoric, sulfuric, and hydrochloric acids. |
