Animal feeds including actives and methods of preparing same

摘要

Improved extrusion-processed daily ration animal feeds are provided which include minor amounts of actives to ensure that an animal consuming the feed receives quantities of the actives sufficient to establish and maintain substantially constant concentrations of the actives in the animal's bloodstream. The feeds may be produced by extrusion with addition of minor quantities of one or more actives so as to uniformly distribute the actives throughout the extruded product.
