A method of forming a granule having an internal three-dimensional framework of channels to control and sustain the release of an active ingredient for enteric delivery of the active ingredient in an animal fed the granule. In the composition of the granules hydrogenated vegetable oil, HVO for example, is combined with a modifier to create a granule with channels through which the active ingredient is released. The active ingredients, including but not limited to metal salts of butyric acid, can be released in the lower gut of the animal where it will best benefit the animal. By adjusting the amount of the modifier, the release rate of the active can be adjusted to suit the passage rate of the species of animal being fed. |
