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.
