Abstract
A heavy density depot for lodgement in the remeno-reticulum of a ruminant animal and progressive release of veterinary substance, comprises an elongate body containing the veterinary substance and having an aperture to allow its progressive release, and a domed weight at a leading end of the body to facilitate passage down the animal's oesophagus. The weight is usually outside the body. The construction is particularly compact so maximizing the amount of veterinary substance contained.
