The tagging procedure is very important both for the welfare of the animal and for tag retention.

We send a leaflet out with every applicator (reproduced here):

Using the SET Tag Applicator

Practically, none. RFID stands for Radio Frequency Identification while EID stands for Electronic Identification. Both terms are used widely, but some people tend to use EID to refer to the unique ID number of the animal and RFID to refer to the technology.
The transponders or microchips used in Shearwell tags have a very low failure rate. They are ISO 11784/5 compliant, high performance chips with an excellent read range. Should the electronic tag on a particular animal fail to read, check its identity from the tag and order a replacement.
When used with Shearwell equipment – stick readers, race readers, weigh crates etc. – transponder detection is excellent even in 'noisy' environments such as abattoirs, markets etc. We use high performance ISO 11784/5 compliant chips with an excellent read range for accurate, rapid reading. We believe ours is the best performing electronic ID package on the market.
Yes. Shearwell readers are bi-modal (reading both HDX and FDX technologies) and can detect RFID devices, including boluses, in sheep, cattle, pets and even fish.
Retention rates for Shearwell SET sheep tags in trials exceed 99.5% so this is unlikely to happen.

When re-applying tags, check for and treat any possible infection that may be caused if the tag has somehow been wrenched from the ear.
See the chart on the tag page
Animal IDs are read by the Shearwell Stick Reader (and Race Reader) and the information can be transferred wirelessly using Bluetooth to computers and other devices.

This information can then be used as the basis for efficient and practical individual animal management. Instead of basing your decisions across a whole mob, you can tailor treatments individually to optimise output. The Shearwell SET tag system is compatible with a range of reader and management equipment.
No. Not for sheep in New Zealand
The Shearwell SDL 400 Stick Reader can store up to 16,000 individual animal EIDs. This data can be downloaded to other devices via Bluetooth.
Since long before it was called ‘genetics’, livestock farmers have taken note of their best performing animals and practised selective breeding. Now the information that used to be stored in the farmer’s head or notebooks is available on computers. Electronic identification of individual sheep has empowered farmers to record increasing amounts of information about their mob so they can make better informed decisions. It has become possible to really identify which are the profitable animals, which fatten best, which show the best conformation, which ewes make the best mothers, which animals are most resilient or resistant to disease and parasites. Collecting that data consistently and turning it into useful information helps livestock farmers make better decisions and more profit.
