Abstract
A composition of matter and method for administering a bioactive substance to the post-rumen portion of the digestive system of a ruminant substantially without introducing the substance to the rumen portion of the digestive system is provided. The composition of matter comprises particles which have a specific gravity between about 0.3 and 2.0, preferably between about 1.0 and 2.0. The particles comprises a core comprising bioactive substance; a hydrophobic coating essentially completely encapsulating said core in a quantity sufficient to essentially preclude introduction of bioactive substance into the rumen; and a surfactant applied to the surface of the hydraphobic coating in a quantity sufficient to ensure that said particles do not float on the rumen. The method comprises orally administering this composition of matter to a ruminant.
