Conclusion, Ear Notch Systems
• Ear notch systems are easy applicable• Ear notch systems are relatively safe• Capacity of ear notch systems alone is
too small for traceability systems• Combination with premises identification
and movement records will provide traceability

Ear Tattoo Procedure• Clean the inside of the ear first• Drive the tattoo needles deep into the ear• Avoid where possible, dark skin, hair, cords or
ribs in the ear• Wipe off any blood• Apply immediately plenty of ink on the ear
surface• Rub it in well with an old toothbrush. • Get ink well into holes, so after healing the ink
stain is visible.

Ear Tattoo in theory
• Age at application• Proportional growth ??• Skin colour• Fur, density and colour• Avoid veins, cords and
ribs• Fading of ink

Conclusion, Ear Tattoo• Ear tattoos with six
positions (as shown) may identify individually millions of pigs
• In Australian test readability was o < 56 % eight weeks after
application o < 40% at slaughter
• Readability problems may disqualify ear tattoos is identification tool
Good Production Practice 4 11

Conclusion, Slap Tattoo
• Slap mark tattoos may be difficult to read• Australian evaluation: 72 – 85 % readable • Reading difficult
• improper application• ink faded• dark skin• dark or dense fur• pig dirty
•

Tattoo Slap Marking• Tattoo slap marks often used to identify
holding of origin• 6 position codes provide millions of codes if
some positions are alphanumeric• Identification of farm of origin and movement
records proved sufficient for controlling swine fever in EU
• Combination of tattoo slap and ear notches can provide low cost individual unique identification if tattoos are readable

Ear Tags
• Use high quality tags for permanent identification
• Lost eartag -> lost identity
• Tamperproof• Locking mechanism• Print quality• Proper size
![Page 18: Identification Tools and Technologies for Pigs · Identification Tools and Technologies for Pigs OIE Traceability Conference Buenos Aires, March 2009 Ole Klejs Hansen Senior Adviser,](https://reader034.vdocuments.net/reader034/viewer/2022042710/5f64e63f7e62df7bed402892/html5/thumbnails/18.jpg)

Conclusion, Visual Plastic Ear Tags
• Loss rate is the big issue with ear tags• Loss rates for conventional quality ear tags
recorded at 2–4 % during pigs lifetime • Loss rate depends on housing systems• Loss rate increases if animals are moved or
regrouped• Loss rate during slaughtering 3–4 %
![Page 19: Identification Tools and Technologies for Pigs · Identification Tools and Technologies for Pigs OIE Traceability Conference Buenos Aires, March 2009 Ole Klejs Hansen Senior Adviser,](https://reader034.vdocuments.net/reader034/viewer/2022042710/5f64e63f7e62df7bed402892/html5/thumbnails/19.jpg)
Danish Agricultural Advisory ServiceNational Centre
Conclusion, Visual Plastic Ear Tags
• Easy application• Premises code - Internationally unique
animal ID-code)• Two identical ear tags or combination with
other identification method• Temporary tag or permanent tag• High permance tags as a key factor• Look for independent international quality
tests of ear tags

Common issues, injected transponders
• No visual identification except in combination• Visual indication of injected transponder• Trained people to do injection• Test before and after injection• All transponder must be removed after
slaughter• At the speed of the slaughter line

Intraperitoneal Transponder found after Slaughter
![Page 27: Identification Tools and Technologies for Pigs · Identification Tools and Technologies for Pigs OIE Traceability Conference Buenos Aires, March 2009 Ole Klejs Hansen Senior Adviser,](https://reader034.vdocuments.net/reader034/viewer/2022042710/5f64e63f7e62df7bed402892/html5/thumbnails/27.jpg)

Conclusion Transponders• Subcutaneous injected transponders not
recommended because of loss rates• Intraperitoneally injected transponders provide
very high traceability even after slaughter• Identification quicker with electronic devices• Less reading errors (”read” or ”not read”)• EID enables automatic recording and
reporting to traceability database and automated management.

Recommendations, Transponders
• ISO 11784 and 11785 are the international standards on transponders for animal identification
• Low frequency type (134.2 Khz)• Signals penetrates water and body tissue• Relatively short reading distances• Individual handling of animals• ICAR is Registration Authority of ISO• All approved transponders can be seen on ICAR
website.
