The Michigan Department of
Agriculture (MDA) has set the date of
March 1, 2007
, by which all cattle must be
identified with Radio Frequency Identification
Device (RFID) electronic ear tags prior to movement from
a premises. After
that date, animals will not be allowed
to move with official metal ear tags or
official registered breed tattoos as their
recent change is in support of
�s Bovine Tuberculosis Eradication Program.
The use of RFID tags decreases the time and money
required to trace animal movement within
will be using the new Animal Identification Number (AIN)
system which allows each animal to be identified with a
lifetime number. The
format for the AIN is 15 numeric characters, the first
three being a country code which, for the
is 840. EXAMPLE: 840123456789012.
As animals are bought and sold during their
lifetime, the tag is never changed unless lost, and then
the animal will be retagged at its current premises.
Before any tag
orders can be placed, producers need a National Premises

(USDA) will assign one permanent number to each premises
(location) involved in animal agriculture.

As part of its
ongoing efforts to safeguard
animal health, the U.S. Department of Agriculture (USDA)
initiated the implementation of a National Animal
Identification System (NAIS) in 2004.
The NAIS is a cooperative State-Federal-industry
program administered by USDA�s Animal and Plant Health
Inspection Service (APHIS).
A National Animal ID system will dramatically
improve our ability to respond to animal disease
a contagious disease outbreak, time is actually the
more time it takes to track an animal, the more animals
are exposed, the more premises become involved, and the
more money it costs to contain the disease.
An animal ID system will help animal health
officials identify the birthplace of a diseased animal
and shorten the time required to trace the animal�s
history to identify other potentially exposed animals.
Michigan Department of Agriculture in November 2001
received a grant for $1.3 million for livestock
identification related to bovine tuberculosis (TB), USDA
officials might not have known what kind of results to
expect. The program has evolved into a highly effective
animal identification and tracking program. The program
has demonstrated its ability to be the framework for the
National Animal Identification System.
recent USDA station review and audit the Animal Industry
Division was assigned 30 metal ear tag numbers and 30
RFID tag numbers with the intent to locate the animals
in 24 hours. Staff in the division located all 60 tags
along with the farm locations in 30 minutes. Excellent
support by staff both in the office and field along with
producer participation is the only way this type of
result will occur.
