IYAK Ear Tag System May 2015

The IYAK registration was started in 1993 as The North American Yak Registry (NAYR). It was designed to follow the year/letter designation published by the Beef Improvement Federation (BIF). This is an internationally recognized system of assigning a letter to each year in alphabetical order. It is widely used among livestock breeds. The

sequence is published on the IYAK website.

During the first year of registration (1993) all yaks were given registration numbers and ear tags beginning with the letter C, which was the year-letter for 1993. This grouped yaks whose birthdates were unknown with the calves actually born in 1993, a somewhat confusing convention

that was followed for the first several years. (That is why, for example, Queen Allante is D171 while her calf Prince Allante is C020.) All calves born in 1994 were given registration numbers starting with the letter D, 1995 starting with E, and so on thru the sequence. The first IYAK tag, C001, was given to Sargent Pepper, an adult Royal bull at the time.

The system is designed such that the letters I, O, Q and V are not used as these letters can be confused with numbers on tags when viewed from a distance. The year/letter sequence was written in the original NAYR rules but somewhere along the way NAYR fell out of sync with the BIF. In 2010 U and V were skipped to bring the

NAYR back into sync with the BIF.

The year 2015 presents to NAYR a special situation. We have completed our first cycle thru the letter system and are back to C for the letter year 2015 in the International System. How do we differentiate registration numbers in the first cycle from those in the second, both on registration certificates and in CattleMax?

The IYAK BOD unanimously agreed to the following solution at the May 3, 2015 meeting:

Starting with the second letter cycle in 2015, the registration number designated on the certificate will be 2C001. Subsequent registration numbers will be 2C002 and so on thru 2C999. However, it was decided to not put the cycle designation prefix 2 on the eartags as it adds too many characters, making it hard to read in the field and on registration photos. So, the first calf registered in 2015 will have a certificate number of 2C001 and a tag number of C001.

22 years from now we will complete this second cycle and registration numbers will start with 3: 3C001, 3C002 and thru 3C999. This gives us an infinite number of cycles and 999 registrations per year.

It will be the responsibility of the present and future Registrars to see that the International System is followed for the letter sequence.

As for the tags themselves, the IYAK BOD agreed unanimously on 05/03/2015 that, effective immediately, we will provide Z tags in the “cow” size for all animals accepted for registration. We feel the consistency achieved by this decision will be benefit IYAK members as a whole. If this does not fit in with your current livestock operation, you are welcome to supply your own eartags but they must conform in size, shape and text with the tags provided by IYAK.

Z Tag application tools can be found at most feed and animal supply stores and online.
