The present invention relates to a device for administration to the mammary gland cavity of a subject including at least one active agent; and, at least one carrier material; and, characterised in that the environment into which the device is inserted into activates dispersion of the active agent. In further embodiments, a muco-adhesive material is used as a retainer material for the carrier material / active agent mixture. The aim of the device is to deliver active agent or agents to a subject in the form of a suppository that, on administration to the subject, disperses into the subject environment. The device is particularly useful for delivery of an active agent to the mammary gland of a lactating cow.
