Abstract: The invention relates to a sanitant arrangement for the application of matter and/or one or more articles to an animal, the arrangement including a member which pierces the skin or hide of an animal. The arrangement further includes a thixotropic sanitant gel, into or through which the member passes before and/or after each use. The invention includes a vaccinator for applying matter such as by injection, and a veterinary appliance for applying identification means to animals. The thixotropic sanitant gel preferably has an oil base, from about 5% to about 9% (W/W) colloidal silicon dioxide and from about 1% to about 10% (W/W) sanitant substance.

Abstract: The subject matter relates to an applicator for applying matter to be applied, such as vaccine, to animals. The applicator includes an applicator head which incorporates a chamber and needle. The needle is at least partially surrounded by a generally elongate proboscis or cover which is capable of axial movement over and relative to the needle. A reservoir for matter to be applied or vaccine, is provided and is attached to the applicator head. Valving connects the chamber with the needle and also connects the reservoir with the chamber. Predetermined axial movement of the proboscis or cover relative to the needle opens the valving between the needle and chamber and allows matter within the chamber, such as vaccine, to be passed from the chamber through the needle. The chamber is provided with a movable wall and actuating means connected to a trigger.
