NLIS cattle devices

There are two types of NLIS devices (tags) endorsed for the permanent identification of cattle:

  • White breeder tags – used by a breeder to permanently identify cattle before they leave their property of birth.
  • Orange post breeder tags – used to permanently identify introduced cattle that have lost their original breeder device.

NLIS devices come in the form of an ear tag, or ear tag and rumen bolus combination.

All cattle must have an NLIS device applied to the ear before leaving the property. In most cases this will be their property of birth and therefore must be fitted with a white breeder tag. This tag must not be removed until the animal is slaughtered.

Breeder tags have a unique number printed on the outside of the device which includes the Property Identification Code (PIC) of the property of birth.

Orange post breeder tags are applied when cattle are missing a tag, but were not born on that property ie an animal bought from another property.

If an animal was not born on your property it must not be fitted with a white breeder tag.

If cattle you buy are already identified with an NLIS device, do not attach a second NLIS device or remove the device and replace it with one of your own.

Remember: One animal = One tag for life

How to order NLIS devices

To order NLIS devices you must contact or go to your local reseller (eg Elders, Landmark, or CRT) and provide the following information:

  • Your PIC.
  • Contact details.
  • Type of tags (ie either white breeder tags or orange post breeder tags).
  • Name of manufacturer.
  • Number of devices wanted.

Note: From July 2011 PIRSA no longer needs to be contacted when ordering NLIS cattle tags.

How to apply NLIS devices (tags)

Applying tags correctly first time avoids the cost and inconvenience of re-tagging

Cattle only need to be permanently identified once, either with an NLIS breeder tag or an NLIS post breeder tag. If cattle are already identified with an NLIS tag, do not remove the tag or attach a second NLIS tag.

When tagging cattle remember:

The correct location of a cattle NLIS device
  • A convenient time to attach an NLIS tag is at marking on beef properties and at weaning on dairy farms. Cattle are easier to restrain for tagging when they are young.
  • To maximise tag retention, you need to carefully read the instructions that you receive with your NLIS tags. After application, tags cannot be reused.
  • You must use the correct applicator. If an incorrect applicator is used, tag retention will be compromised and the microchip in the tag may be smashed.
  • Cattle must be tagged in the right (off-side) ear (see image).
  • When tagging cattle with NLIS tags make sure you follow the manufacturer’s instructions. The correct position for NLIS tags is shown below for maximum retention.
  • If you have a problem with the retention rate of the NLIS tags you are using, contact the tag manufacturer.
