Abstract: Production of a polymer-coated granulated animal feed additive containing enzyme(s). Production of a polymer-coated granulated animal feed additive containing enzyme(s) comprises: (1) granulating a mixture of a suitable feed carrier and enzyme(s); and (2) coating the granulate with a suitable organic polymer (I) by spraying the granulate with a melt, solution or dispersion of (I) or coating with (I) powder in a fluidized bed or in a mixer. If necessary, the coated granulate is dried, cooled and/or freed from coarse particles. Independent claims are also included for: (1) granulated animal feed additives of this type, coated with a specified organic polymer; and (2) pelletized animal feed compositions containing additive(s) of this type mixed with usual constituents.
