National Animal Identification System
What is the National Animal Identification System
Spurred by recent outbreaks of mad cow and other forms of disease within the livestock
industry and global governmental global efforts to reign control over animal production, the National Animal
Identification System (NAIS) is designed to track all agricultural animals as they come into contact, are mixed
with or interact with herds and as they move through the supply chain.
Ideally, the NAIS will enhance U.S. efforts to respond to intentionally or
unintentionally introduced animal disease outbreaks more quickly and effectively. The United State Department of
Agriculture's long-term goal is to establish a system that can identify all premises and animals that have had
direct contact with a foreign animal disease or a domestic disease of concern within 48 hours of discovery.
Here are some of the most frequently asked questions from the USDA:
Why is a National Animal Identification System needed?
The NAIS allows for rapid tracing of animals in the event of an outbreak, helping
to limit the scope, spread and expense of the outbreak and minimizing the mpact on the industry as a whole. The
NAIS will also be critical as USDA, States, and industry work to complete the disease eradication programs in which
we have invested many years and millions of dollars. The NAIS may have merit for producers for other reasons as
well, including providing additional marketing opportunities.
What is meant by the term "animal identification"?
Animal identification links each animal with a number and then links that number
to a registered premises.
What is meant by the term "animal tracking"?
Animal tracking is the final step and consists of recording animal movements from
one premises to another.
Is the NAIS related to the Country of Origin Labeling (COOL) initiative?
The COOL program is a food labeling program designed to provide source of origin
information to the consumer while the NAIS is a live animal tracking program designed to address animal disease and
health concerns quickly. While the mechanisms to implement these programs may be similar, they are not currently
What is the timeframe for implementation of this program? What do I need to do now (2005)?
The NAIS program is currently completely voluntary. USDA focused on establishing
the processes for acquiring a premises identification number (PIN) in 2004 and 2005. More on this process is
indicated below. Acquiring a PIN is voluntary in most states. The national focus will now turn to determining and
establishing standards and procedures for acquiring official animal identification numbers (AIN) and for tracking
animal movements. Official AINs should be available by the fall of 2005. Producers are not required to do anything
at this time (May 2005). If a producer is interested in registering their premises, they can contact the state
animal health official for assistance. If a producer is interested in using electronic tags, they should look into
the optional resources detailed below.
Why should I tag my cattle and should I do it now (2005)?
Animal identification is one of the key elements of the National Animal
Identification System. Each livestock animal will need an official Animal Identification Number (AIN) that is a 15
digit number beginning with 840 (representing the U.S.). NAIS remains completely voluntary at this time (May 2005),
so many producers are using individual animal identification to improve on-ranch record keeping and management
strategies, to market their cattle to specific verifiable programs, or to meet the requests of buyers and/or
feeders. The cattle working group recommends that the tag be placed in the left ear and suggests that each tag
company provide directions on how tags should be placed and applied. Attaching the official identification tag
consistently in the left ear will help create more awareness that it is the official tag and not to be removed.
Proper placement in the ear improves retention and the instructions from the tag manufacturer should be followed by
producers when tagging their cattle. Unless you are interested in the advantages of management, processing and/or
carcass data, tagging livestock with an electronic tag is not necessary at this point as NAIS is still voluntary.
If you are interested in collecting data on your herd, check with one of the programs detailed below.
How do I get involved in a program to individually identify and track my livestock?
There are several programs available that provide individual animal
identification methods and maintain data in a nationwide private database. Listed below are some of the
1. Check with your breed association to see if they have a program started. For example, the American Angus
Association has AngusSource, and can collect and communicate breed identity, genetic composition, past performance
history and management practices on feeder calves, stocker cattle and replacement females
2. Private data companies can help you identify and track your livestock through radio frequency electronic
identification tags. Options include eMerge Interactive, AgInfoLink, APEIS, IMI Global, and Micro Beef Technologies
(see Resources below).
3. If you are interested in a biometric identification option, check with your local veterinarian about options
for DNA testing and identification. Optibrand has a system that will record the retinal vascular pattern of the
4. Check with your Extension agent or your land grant university to see what other programs may be available to
you. In Montana, that includes the Montana Beef Network, a cooperative project that has identified and tracked
cattle since 1999 for value added and marketing purposes.
5. Check with the auction market or video auction sales company handling your cattle to see if they have any
programs available. For example, Superior Livestock Auction is starting a new voluntary identification program
called VASE (Verified Age Source Electronically identified).
6. Finally, check with your state industry associations. The staffs of those organizations are watching this
program develop and can direct you to viable options for your operation.
