Process for the preparation of granules of active principles by extrusion

摘要

The invention relates to new granules as well as to a process for their preparation, the granules being obtained by extrusion of a mixture containing a fusible binding agent in an amount such that it enables the mixture to pass through a die. The granules obtained are then coated with a polymer which enables them to pass through the rumen without degradation. …These granules after coating are used in animal feeds for ruminants.
