Controlled release capsule

摘要

A device for the sustained release of into the rumen of a ruminant animal has an elongate, tubular body for housing a therapeutic or nutrient composition. Wings are pivotably attached to one end of the body member and are resumably biased away from a storage position, in which they extend along body member, an operative position. In the operative position, the wings are at a pre-determined angle to the longitudinal extent of the body member and are constrained from pivoting beyond this angle.
