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.
