Tagging regulations

  • Any purchased cattle should have a ‘primary’ NAIT approved RFID tag AND an official ‘secondary’ tag.
  • Farmers will need to record any off-farm cattle movements with NAIT, unless they are to a NAIT accredited meat processor or a NAIT-accredited sale yard.
  • Cattle arriving onto or being born (except bobby calves) on the farmer’s property require a primary RFID ear tag and secondary tag. All off-farm cattle movements are recorded with NAIT, unless to a NAIT-accredited meat processor or sale yard.

Bobby calves

Under the NAIT scheme, bobby calves are classed as less than 30-days-old and going direct to slaughter. Bobby calves are not included in the NAIT scheme as they are considered a low biosecurity risk. Simply tag a bobby calf with an ear tag issued by your meat processor. You are not required to use a RFID ear tag for bobby calves and you do not need to record a bobby calf’s movement with NAIT.

Accurate calving records,made easy; Gene Mapping’s as simple as applying an eartag.

Creating calving records with ease is one benefit of DNA testing. Gene Mapping identifies the sire and dam as well as the A2 type beta casein status.
The Gene Mapping service uses a new Allflex Birth Tag which takes the sample at the same time as applying the ear tag. Also available in a button tag format for the herd.
This provides many wins – it’s less invasive for the animal, faster for the farmer with only one action required, and provides a visual marker to confirm the animal has a DNA profile. Most importantly, the Allflex tag
system leaves no room for error. You’ll have 100% confidence that the results correctly link the sample to each animal.
