PigPass, PICs, and why pig tags matter
In most Australian states, pig traceability links pigs to the Property Identification Code (PIC) of the property they move from, supported by movement documentation (often a PigPass NVD) and database reporting. PigPass is designed to link pigs to a PIC, tag or brand/tattoo, and a movement document—supporting biosecurity and food safety across the supply chain. (State and territory requirements can differ, so check your local rules before dispatch.)
Ear tag vs tattoo brand
Pig identification rules commonly depend on the pig’s weight and whether the animal is leaving its property of residence. A typical approach is:
Lighter pigs/weaners: ID via an NLIS-approved pig ear tag
Heavier pigs: ID via a registered tattoo/slap brand (threshold varies by state)
For example, industry guidance notes slap branding is the primary method for pigs above 25 kg liveweight (above 30 kg in Queensland), while NLIS-approved pig tags are commonly used for pigs under 25 kg. Keep in mind: pig tags are different to cattle and sheep/goat NLIS tags, and you should only use devices intended for pigs.
Best-practice tagging for retention and welfare
Good tag retention starts with correct application and clean gear. Before tagging:
Use the correct applicator for your tag type and check the pin isn’t bent or blunt
Keep tags clean and keep the tag site free of dirt/manure
Keep applicators clean and disinfect between animals during a tagging run where practical
Restrain pigs safely to avoid misplacement and injuries to handlers
If you’re tagging for movement/compliance, also build a habit of checking your PIC details and your movement documentation process before dispatching pigs.
