Abstract
A time release bolus comprises a tubular member and an end cap secured to each other. The tubular member contains an inner bag which is adapted to receive and contain a nutrient or medicament substance. A capsule is provided in the tubular member, and upon fracture thereof, applies pressure to the inner bag. The end cap includes a plug which fits into an open end of the tubular member and a top portion. A passage is provided which leads from the tubular member to the exterior, such that nutrient or medicament can flow from the inside of the tubular member to the outside of the time release bolus. The bolus further includes in the end cap a mesh in the flow path of the substance, the mesh further restricting and controlling the amount of substance which may pass from the bolus to the exterior. Wings are provided on the end cap which are movable between a first retracted position where insertion per os of the bolus takes plus, and a second extended position adopted in the rumen to prevent regurgitation of the bolus.
