The present invention relates to novel phytase-comprising enzyme granules, the particles of which have a weight-average particle size in the range from 300 to 800 mum and the specific phytase activity of which, expressed in FTU/g, is at least 13 000 and does not exceed a value of <；?in-line-formulae description="In-line Formulae" end="lead"?>；FTUmax=6000[FTU g-1].D-3.mm3,<；?in-line-formulae description="In-line Formulae" end="tail"?>； D being the weight-average particle diameter of the granule particles in mm. The invention further relates to phytase-comprising enzyme granules for feeds, the particles of which have a weight-average particle size in the range from 300 to 800 mum and the specific phytase activity of which, expressed in FTU/g, is at least 7000, and does not exceed a value of <；?in-line-formulae description="In-line Formulae" end="lead"?>；FTUmax=2000[FTU g-1].D-3.mm3,<；?in-line-formulae description="In-line Formulae" end="tail"?>； D being the weight-average particle diameter of the granule particles in mm. 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.
