    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.

    Abstract: The present invention relates to novel methods for producing coated granulated enzyme-comprising feed additives, to the coated enzyme-comprising granules produced in this manner, and also to feed compositions which are obtainable using the coated granules. This method comprises the following steps: a) Extrusion of an enzyme-comprising dough which, in addition to water, comprises i) 50 to 96.9% by weight of at least one solid carrier material suitable for feed, ii) 0.1 to 20% by weight of at least one water-soluble polymer, iii) 3 to 49.9% by weight of at least one enzyme, the weight fractions of i), ii) and iii) in each case being based on the nonaqueous components of the dough; b) final-processing the extrudate to give raw granules having a water content of no greater than 15% by weight, and c) coating the raw granules with a hydrophobic material selected in an extent of at least 70% by weight, based on the hydrophobic material, from saturated fatty acids, the esters of saturated fatty acids, in particular the mono-, di- and triglycerides of saturated fatty acids, and mixtures thereof.

    Abstract: The present invention relates to novel phytase-comprising enzyme granules, those particles of which have A) a core which comprises at least one phytase and at least one solid carrier material suitable for feeds, and b) a coating arranged on the core, the cores of the particles or the entire particle, after if appropriate required grinding, on suspension or dissolution in demineralized water at 25° C. giving a pH in the range from 4.5 to 6.5, preferably in the range from 4.6 to 6.0, and particularly preferably from 4.7 to 5.5 and which are suitable as feed additives, and also a method for production thereof. The invention also relates to the use of the phytase-comprising enzyme granules in feed compositions and, in particular, pelleted feed compositions, which are obtainable using the phytase-comprising enzyme granules.

    Abstract: The invention relates to a method for producing granulates which contain enzymes and which are suited for feeding animals. The granulates are produced by mixing at least one enzyme with a supporting material and by extruding this mixture. The inventive method is characterized in that the supporting material is firstly plasticized in a screw mixer which is equipped with at least one horizontally arranged screw. Afterwards, the enzyme is introduced into the screw mixer and is processed with the plasticized supporting material to produce a homogeneous material which is then extruded.
