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.
Claims9
A process for making a coated granule having a minimum density of about 1.2 g/ml which contains an active principle selected from the group consisting of medicaments and amino acids intended for feeding ruminants comprising;
- extruding a dry mass of the active principle in the presence of a meltable binder in a molten state in an amount of less than 25% by weight, but in an amount sufficient to permit passage of the mixture of at least the active principle and meltable binder through a die;
- and coating the extruded core with a protective agent.
