Abstract

Method for identifying an animal wherein a transponder is (3) introduced in the animal. To prevent infection of the wound site, together with the transponder (3) a disinfectant is introduced. According to the invention, this disinfectant is present in a bioabsorbable tablet (14) and this tablet (4) is introduced in line with the transponder.

Claims

1. A disinfectant/transponder assembly for introduction into a living creature, comprising a bioabsorbable tablet disinfectant essentially having the same cross-sectional shape as the transponder wherein aid bioabsorbable tablet is introduced into the living creature in front of said transponder.

2. A disinfectant/transponder assembly according to claim 1, wherein one end of said bioabsorbable tablet is joined to said transponder and said other end of said bioabsorbable tablet which first comes into contact with said living creature is pointed.

3. A method for providing identifying information relative to a particular living creature comprising the steps of:

introducing a transponder under the skin of said living creature together with a disinfectant, wherein said disinfectant is present in a bioabsorbable tablet and is introduced in line with said transponder.

4. A method according to claim 3, in which the disinfectant is introduced in front of the transponder.

5. A method according to claim 3, further comprising making a U-shaped cut in the skin of the living creatures, folding back the section of skin thus formed and inserting the transponder and the disinfectant.

6. A disinfectant/transponder assembly for introduction into a living creature wherein said disinfectant comprises a carrier material with a disinfectant incorporated therein, and said carrier material has essentially the same cross-sectional shape as said transponder.

7. A disinfectant/transponder assembly according to claim 6, in which the carrier for a disinfectant contains polylactic acid.

8. A disinfectant according to claim 6, in which the carrier consists of protein which corresponds to the proteins of the living creature into which the transponder is introduced.
