Abstract: An animal tag for attachment to the flesh of an animal with the tag characterized by having a portion of the tag containing a film coating containing an antiseptic for release into a wound made in attachment of the tag to the flesh of the animal to thereby inhibit bacterial infection in the wound.

Abstract: A method and phase changing composition with an in situ insecticide for the killing of insects on animals over an extended period of time. The phase changing composition with an in situ insecticide comprises a film-former such as hydroxypropyl cellulose, ethyl cellulose and methyl cellulose, an insecticide and a rapidly evaporating solvent such as volatile alcohol. When the phase changing insecticide composition is applied to an animal, it leaves a liquid bead on the animal which penetrates and encapsulates a portion of the animal's body hairs. As the liquid solvent in the liquid bead evaporates, it forms a dry-to-the-touch gel bead that contains the in situ insecticide which is released from the gel bead over an extended period of time.

Abstract: A method and composition for the prevention of mastitis in animals. The composition comprises a water soluble film former such as hydroxypropyl cellulose, ethyl cellulose and methyl cellulose, and chlorhexidine (preferably as the gluconate), carried in a freeze-resistant, rapidly evaporating solvent comprising a volatile alcohol. When animal teats are dipped into the composition, a liquid film containing chlorhexidine remains on the teats, and the liquid vehicle quickly evaporates to form a protective film that coats the teats to prevent bacterial infection.
