RFID Animal and Livestock Identification

RFID for Livestock and Animal Identification

Sheep RFID


Texas Instruments RFID (TI-RFID™) low frequency (LF) RFID technology has been used to identify millions of livestock animals around the world. These systems track meat and dairy animals, valuable breeding stock and laboratory animals involved in lengthy and expensive research projects. The Australian National Livestock Identification System (NLIS) is the first and the largest implementation of RFID for animal tracking in the world.

RFID transponders are worn as ear tags or as an inter-ruminal capsules. Farm management can be fully automated for such processes as feeding, weighing, disease management, and breeding practices.

Low frequency (LF) RFID, with an operating frequency of 134.2 kHz, has been adopted internationally for animal identification applications following many years of development, exhaustive testing and practical field evaluation.

The International Standards Organization (ISO) and the Australian/New Zealand standards for the electronic identification of animals are based on LF 134.2 kHz RFID technology. (ISO11784/11785, AS5018/5019) The Texas Instruments LF RFID technology was selected by the ISO as the basis for these standards.

TI-RFID™ 134.2 kHz LF technology has been adopted by the NLIS in Australia after exhaustive field testing of all available technologies. Through these trials the TI-RFID half-duplex (HDX) technology was demonstrated to have superior performance under practical conditions. NLIS tags have now been in use for several years, with great success.

Over a period of 10 years or more, suppliers of non-conforming technologies have challenged the use of LF RFID for livestock. Despite these challenges TI's LF 134 kHz HDX RFID still delivers the best cost: performance ratio for the livestock industry.

Texas Instruments 134.2 kHz LF RFID uses frequency modulation and half duplex techniques. This unique approach gives the most robust performance and best read-range in its class. The tags are passive components (i.e. no battery), which combined with TI's legendary quality and reliability, means they continue to operate for many, many years.AnimaLife Antenna

The ISO standards also encompass full duplex (FDX) 134 kHz technology. Although full duplex tags are cheaper and suppliers often claim that they will perform as well as HDX technology, these claims have not been supported during field evaluation with walk-through readers. For this reason, HDX tags are used almost exclusively for livestock where performance and reliability are important. FDX tag performance is adequate where animals can be individually handled and scanned with hand-held readers.

TI HDX transponders used for livestock identification are factory programmed with a unique 64-bit code which is tamper proof and cannot be duplicated. All animal data is stored in secure data-bases where it can only be accessed by authorised users.

The leading suppliers of cattle identification products have now integrated TI-RFID technology into their ear tags. Eartag manufacturers are carefully qualified by Texas Instruments, and must obtain ICAR (international) and NLIS approvals before releasing their products. These tags are now being rolled out progressively in Australia , state by state, to support the NLIS implementation. Millions of tags have been deployed to date (2007).

The Australian meat and livestock industry is regarded as one of the most efficient and cost effective in the world. By nature it is also conservative, pragmatic and cost sensitive.

At present, the identification of sheep using RFID technology is not yet mandatory, but may soon become necessary when a nominated RFID standard has been agreed upon by the NLIS & Sheep-Cooperative Research Centre.

LF 134.2kHz technology is proven to be the most effective technology for livestock identification. It is currently being used for cattle identification therefore making it the logical choice for sheep identification. Other technologies are being considered but the performance and reliability is still questionable. LF 134 kHz HDX RFID technology is the only system that has long term, proven performance in the field with large animals.

RFID identification for sheep is seen to have many advantages over current line-of-sight tagging systems.

There are many disadvantages of current NLIS sheep identification techniques such as:

Difficulties in visual sheep methods (requiring manual animal restraint)
Build up of grime on the tag obscures barcodes
Sheep management currently occurs on a flock to flock basis, the benefit and value of identifying individual sheep is not being taken advantage of.

Sheep trials using the 134.2kHz TI-RFID technology have shown the following advantages:

Automatic capture of identification data with long range and high throughput capability
Easier management of flock information- the reduction in the need for paperwork and manual input
Electronic identification eliminates never-ending paperwork and allows farmers to have accurate livestock data on hand
Allows for speedy information and statistics retrieval
Allows for individual sheep management
Accurate traceability for animal disease management
Significant cost savings within the wool pipeline
Ability to scan the RFID tags to utilize artificial insemination data, fleece weights, pregnancy testing, fiber testing and tracking of every sheep on a farm.

NLIS -National Livestock Identification System

About the NLISNLIS logo
NLIS is Australia's system for the identification and tracing of livestock. It is a permanent identification system that enables individual animals to be tracked from property of birth to slaughter for food safety, product integrity and market access purposes.

NLIS uses RFID devices to identify cattle. NLIS approved devices come in the form of an ear tag or rumen bolus/ear tag combination. Cattle are tagged with NLIS devices only once in their life.

Cattle identified with NLIS devices can be electronically read as they move through the livestock chain. At time of reading, each owner's PIC can be recorded and linked to the NLIS device. This transaction information is then stored in the secure central NLIS database.

Once full transaction recording is in place, a life record of an animal's residency, and which other animals it has interacted with, will be established. It is this centrally stored electronic history of an individual animal's residency that will enable rapid and accurate traceability.
