2014 Annual Report and Statistics Now Available

(April 21, 2015) The 2014 Annual Report is now available online. Click here.

The 2014 statistics are also available online and can be found on each association's web page.

Electronic Registration Version 3.11 Released

(April 10, 2015) This release includes several minor program improvements and bug fixes. The most important bug fix related to skipped or duplicated tracking numbers. This affected several members who were submitting multiple applications in the same Appx session. You should now experience more reliable submission of multiple applications.

Please keep us informed of any other apparent malfunctions of the program.

Regarding Appx sessions that unexpectedly end, this occurs because of brief Internet interruptions. This can be caused by your Internet service itself or a loss of signal from your local WiFi or by faulty cables or Internet modems. You may log into Appx again but you will need to re-enter your current application. You do not need to re-enter applications if you have already received a Tracking Number.

If you make an error in an electronic registration and have already received a tracking number, please send us an e-mail and advise us of the names of the animals affected and the requested corrections. A future release will allow you to make your own corrections.<

Inbreeding Coefficient (IC) Interpretation

(March 12, 2015) For the last two years, CLRC has been publishing Inbreeding Coefficients on our website for most breeds.  At the same time, we added a virtual mating option for every animal that includes an IC calculator.

While that additional information is available, it is the member`s responsibility to determine whether the coefficient is useful in making breeding decisions.  There are many sources of information on this subject available on the Internet. 

CLRC cannot provide specific advice on this matter, however, we can give you some idea of how coefficients relate to some easy to understand relationships. This will then give you an idea of how to interpret IC values for your animals in relation to these situations.


Inbreeding Coefficient (%) *

Animal bred to its own parent.
(eg. A son bred to its dam)


Half siblings bred to each other.
(eg. A common sire or dam)


Full siblings bred to each other.
(eg. Both sires and both dams are the same)


Animal has a single common great grandparent on both the sire side and dam side of the pedigree


(*) – This is the minimum Inbreeding Coefficient.  If there is further inbreeding in the pedigree, the coefficient will be higher.

IC values are not precise.  They depend on the number of generations of ancestry available and how many generations are analysed.  In general, the more generations of ancestry that are analysed, the higher and the more accurate the IC will be. 

In addition, IC values will vary between breeds depending on the breed history and the genetic diversity that exists within that breed.  If the genetic diversity is historically narrow (limited bloodlines were available), then IC values will tend to be higher for that breed.  This illustrates the importance of bringing in new blood lines occasionally (perhaps from other countries) when possible. 

CLRC`s virtual mating IC calculator does a 5 generation analysis by default.  In most cases, this gives a reasonable estimate of the coefficient.  There is also a 12 generation option which will give more accurate results but the response time for the calculation is noticeably slower.  Please be patient if you choose the 12 generation option. 

You should also be aware that when you recreate parent combinations for existing registered animals using the virtual mating IC calculator, you may not get the same IC value as posted on the website for the existing registered animal.  The IC value that we display for registered animals take into consideration the entire ancestry in the database, regardless of the number of generations available.  The displayed IC values will tend to be higher (and more accurate) than those provided by the virtual mating IC calculator.

(June 11, 2014) **Please note that this bulletin only applies to Quantum (Genserve) customers, which excludes horse breeds other than Warmbloods.

All breeders who use the services of Genserve Laboratories Inc. (now owned by Quantum Genetix) are asked to note the following changes regarding applying for DNA testing.

  1. Genserve Laboratories Inc. will no longer be accepting hair samples that are not accompanied by a test application form that has been prepared by CLRC.  Breeders are advised that they must now obtain a DNA test kit from CLRC and then send that with the hair samples to Genserve. If this is not done, the samples will not be processed.             To request a DNA test kit, you may:

    a) Download, complete and submit the DNA Kit Request form click here.; or
    b) Call or  e-mail CLRC with the details about the animal for  which the kit is requested

If the test kit is needed quickly, the printed application form can be e-mailed to you and then you can put the hair samples in a plain envelope on which you have written the animal’s name, sex, birth date and identification and mail the envelope and the application form to Genserve. 

    2. Please note the new  address for Genserve Laboratories Inc. as follows:

Presentation Regarding Animal Pedigree Act

(April 22, 2014) A very worthwhile session concerning the Animal Pedigree Act, and the possibility that it might be repealed, took place during the CLRC Annual Meeting in Calgary on April 5th. About 75 people representing a broad group of the Canadian breed associations were present to hear John Ross of Agriculture and Agri-Food Canada outline why repeal of the Act is being considered.

To view the Powerpoint slides that Mr. Ross used, click here. To read a full transcript of the presentation and ensuing discussion, click here. During the meeting, those present nearly unanimously expressed their strong opposition to repeal of the Animal Pedigree Act.

Sending Photographs by E-mail

(May 10, 2013) For those breeds which require photographs of animals to be submitted with applications for registration, CLRC recommends that breeders scan the application forms and e-mail them, along with the required photographs, to CLRC.

Photographs e-mailed directly from a digital camera chip are very often superior in quality and reproduce better on the certificates than printed photos that must then be scanned by CLRC staff. E-mailing both the application and photographs will save mailing time as well. In these cases, we do request payment by credit card or that you have a credit balance on file.

For transfers, the photographs can still be e-mailed with a copy of the transfer application and certificate, but the original certificate must then be mailed to CLRC.

Updates to CLRC's Electronic Herdbook

(Updated daily) The CLRC Electronic Herdbook is updated daily.

Inbreeding Coefficients and Virtual Mating

(April 11, 2013) CLRC announces that Inbreeding Coefficients are now published on our website for all breeds except Swine. We hope to add Swine in the near future.

Inbreeding Coefficients measure the degree of repeating or common ancestors that exist in the pedigree. Coefficients are measured as a percentage from 0% to 100% or values from 0 to 1. Our website uses percentages. An animal with a coefficient of 0% has no known common ancestors that appear on both the sire and dam side of the pedigree. If you were to breed an animal to its sire or dam, the resulting offspring will have an inbreeding coefficient of at least 25%, depending on the number of other common ancestor lines that might appear in the pedigree.

In addition, CLRC now offers a virtual mating service which will determine the inbreeding coefficient for a proposed mating and display a five generation pedigree and common ancestor list. The virtual mating option appears at the bottom of each animal page and you can select a mate based on member ID number, animal name or registration number. If you select the ID number option, you can select one or more or all animals owned by that member.

Animal Photos and Marking Diagrams now available on-line

On-Line Extended Pedigrees now Show Repeating Ancestry

(November 6, 2012) As step 1 in our efforts to supply our members with more information on repeating or common ancestry, we are now providing additional information with the extended pedigree for each animal in our on-line Members and Pedigrees database. This is accessed here. When displaying an animal's record, there is a link to the extended pedigree near the bottom of the page. This will display a 5 generation pedigree.

What is new is a list of repeating ancestors which is sorted by the percentage of the pedigree that each animal represents. In addition, there is an alphabetic list of ancestors. This latter list will allow you to more easily compare pedigrees of animals that you are considering to mate to identify common ancestry.

Furthermore, we also offer a 12 generation analysis of the pedigree for repeating ancestors. A link appears below the 5 generation tree. You will experience a short delay while the database is doing the analysis.

To clearly show repeating ancestry, the 5 generation pedigree tree is also colour coded. The key repeating males are displayed in bright red and the females in magenta. Their ancestors are displayed in dark red and purple respectively. When an animal does not repeat in the pedigree, it appears in black.

Please watch this page for more related services as they are added.
