  • Patent number: 5688502
    Abstract: A growth promotant comprising microgranules having a core consisting of one or more enzymes selected from: i) protein digesting enzymes; ii) carbohydrate digesting enzymes; iii) fat digesting enzymes; and iv) fiber digesting enzymes in an immobilized form; the core being encapsulated within a water soluble film, and coated with an enteric coating comprising an alkali soluble, acid insoluble polymer, or a high molecular weight polymer whose structure is substituted with or contains windows of fatty acid or other material capable of being solubilized by intestinal juices. A method for increasing animal growth comprising the administration of a growth promoting amount of the growth promotant is also described, as is a method of producing the growth promotant.

  • Patent number: 5597564
    Abstract: A microgranular preparation having a core of biologically active material that is encapsulated by a water soluble film that is covered by an enteric coating of either an alkali soluble, acid insoluble polymer or a high molecular weight polymer whose structure is substituted with or contains windows of fatty acids or other material capable of being solubilized by intestinal juices. Useful for protecting pH sensitive and other biologically active materials from inactivation or contact with the stomach or rumen, and releasing the same in active form in the intestinal tract, particularly the duodenum.

  • Patent number: 5484609
    Abstract: Compositions comprising (i) granules comprising a biologically active material in association with a weak base and partially coated with a delayed release material soluble in intestinal juice, (ii) an acidifying agent having a pH between 1.5 to 6, and (iii) a gel forming agent are described. There is also described a composition comprising an acidic gel having a pH between 1.5 to 6 and containing microgranules comprising a biologically active material in association with a weak base and partially coated with a delayed release material soluble in intestinal juice. The compositions may be used in the treatment of diseases associated with intestinal pathogens in animals. Where the biologically active material is a protease, receptor/adhesion sites in the intestines for pathogens may be proteolysed so as to prevent pathogen binding to intestinal surfaces.
