Abstract

The present invention relates to new granules, as well as the process for their preparation, obtained by extrusion of a mixture containing a meltable binder in an amount such that it permits the passage of the mixture through a die. The granules obtained are then coated with a polymer permitting their trans-rumen passage without degradation. After coating, these granules are used for animal feeding of ruminants.
