Cattle devices
NLIS devices for cattle may either be an ear tag, or a rumen bolus/visual ear tag combination.
Breeder devices are predominately white and are applied to cattle on their property of birth. Post-breeder devices are predominately orange and are applied to cattle no longer on their property of birth, and not already identified with an NLIS-accredited device. This includes cattle that have lost their breeder device after leaving their property of birth.
Permanent radio-frequency identification devices that have successfully completed three-year retention trials under the NLIS (Cattle) Program are granted full accreditation.
Once an NLIS-accredited device is attached properly, it should remain with the animal for life. If you purchase cattle that are already identified correctly, you do not need to apply another device.

More detailed information on devices is available in the NLIS Equipment Compatibility Guide (PDF, 1075 KB).
