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 present invention relates to novel enzyme-comprising granules which are suitable as feed additives, and also to a method for production thereof. The invention also relates to the use of the enzyme-comprising granules in feed compositions and, in particular, pelleted feed compositions, which are obtainable using the enzyme-comprising granules. The particles of the enzyme granules have A. an enzyme-comprising core having a water content below 15% by weight, preferably in the range from 1 to 12% by weight, in particular in the range from 3 to 10% by weight, and especially in the range from 5 to 9% by weight, based on the weight of the enzyme-comprising core, which comprises i) 50 to 96.9% by weight, preferably 55 to 94.85% by weight, and in particular 60 to 89.7% by weight, of at least one solid support material suitable for feeds, ii) 0.1 to 10% by weight, preferably 0.15 to 5% by weight, in particular 0.2 to 2% by weight, and especially 0.3 to 1% by weight, of at least one water-soluble, neutral cellulose derivative, iii) 3 to 49.9% by weight, frequently 5 to 49.85% by weight, in particular 10 to 44.8% by weight, and especially 10 to 39.7% 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 core; and B) at least one hydrophobic coating arranged on the surface of the core, which coating comprises at least one hydrophobic material selected from waxes, saturated fatty acids, esters of saturated fatty acids, polyolefins and polyamides in an amount of at least 70% by weight, preferably at least 80% by weight, in particular at least 90% by weight, and especially at least 99% by weight, based on the total weight of the coating.
