The present invention relates to a chewable formulation for delivering a nutritional or pharmaceutically active agent to an animal target. The chewable formulation comprises a nutritional ingredient or an effective amount of a pharmaceutically active agent, and a plasticiser. The chewable formulation is formed by extrusion and the formulation contains substantially no unbound water, nor is any water added in the manufacturing process. The present invention also relates to a method of manufacturing a shelf stable chewable formulation which comprises mixing the nutritional or pharmaceutically active agent with a fat, lipid or fat and lipid to obtain a first composition, adding one or more plasticizers to the first mixture to obtain a second composition, extruding the second composition at a temperature sufficient to melt the fat and lipid, and allowing the extruded second composition to cool to room temperature thereby providing the chewable formulation. |
