Male and female tag members have respectively a projecting portion for extending through the part to be tagged and a receiving portion for accommodating an end part of the projecting portion after it has passed through the part to be tagged. The receiving portion is in the form of a closed container defining a cylindrical chamber containing sterilizing substance. The action of fitting the tag assembly to the part to be tagged causes the projecting portion to pierce a weakened portion of a wall of the chamber resulting in release of sterilizing substance from the chamber, for example for sterilizing the wound formed when the assembly is fitted to an animal's ear. In a variant the sterilizing substance is replaced by a substance having active pharmaceutical properties. |
