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.
Claims26
An animal growth promotant comprising microgranules having a core consisting of at least one digestive enzyme immobilized by entrapment within a gel matrix wherein said gel matrix restricts the accessibility of denaturing agents to said at least one digestive enzyme, wherein said at least one digestive enzyme is selected from the group consisting of:
- (i) protein digesting enzymes;
- (ii) carbohydrate digesting enzymes;
- (iii) fat digesting enzymes;
- and
- (iv) fibre digesting enzymes;
- wherein the core is 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, whereby said at least one digestive enzyme is not degraded by contact with fluids in the stomach or rumen.
A method for the production of an animal growth promotant comprising the steps of:
- (a) immobilizing at least one enzyme selected from the group consisting of
- (i) protein digesting enzymes;.
- (ii) fat digesting enzymes;
- (iii) fibre digesting enzymes;
- (iv) carbohydrate digesting enzymes;
- by entrapment within a core;
- (b) microgranulating the immobilized at least one enzyme;
- (c) encapsulating the microgranules with a water soluble mechanical barrier;
- and
- (d) coating the microgranules of step (c) with an enteric coating comprising an alkaline 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 administering an animal growth promotant to animals in need thereof, comprising administering to said animal growth promotant comprising microgranules having a core consisting of at least one digestive enzyme immobilized by entrapment within a gel matrix wherein said gel matrix restricts the accessibility of denaturing agents to said at least one digestive enzyme, said at least one digestive enzyme being selected from the group consisting of:
- (a) protein digesting enzymes;
- (b) carbohydrate digesting enzymes;
- (c) fat digesting enzymes;
- (d) fibre digesting enzymes;
- 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, whereby said at least one digestive enzyme is not degraded by contact with fluids in the stomach or rumen.
