Dr. Matt Hegarty has finished his report of the latest findings in the ongoing project researching the genetics of the Hereford breed, and has made the report available to the public.

This project has had several delays, some of which were in the UK, and unavoidable. However, a significant amount of the delay is the result of the very excellent, candid and sometimes heated discussion on this Forum. Many of the ideas, theories, and general comments about the issue of whether or not the Hereford breed is corrupted by other breed genetics, were followed and researched as new data came in. The interest in the issue by the Forum Membership was instrumental and invaluable as a source of support, information and genetic samples that could not have been found anywhere else. Just as important were the discussion and information that gave the researchers a lot to think about. Before, if the results were being checked for errors five times, the forum discussions caused the same checks to occur ten times. The process was slow, but has resulted in a 39 page paper that represents a portion of what is probably the most comprehensive research project ever done on the Hereford breed.
It would be more accurate to say: Hereford breeds, plural, because there are two separate breeds in the Hereford family. They are related, somewhat, but very much apart from each other. Many people reading this Report will be upset, but I think unsurprised, by the results in it.
Another thing that the research was able to do, was to be able to offer breed percentages. This is a win to breeders of North American Derived (NAD) cattle, because even if they aren’t interested in using Original Population (OP) Hereford genetics, the breed percentage test also tests for the category of Unexplained genetics which is a polite name for crossbred, or genetics from breeds other than Hereford (OP or NAD). If the test shows more than 9.9% Unexplained, then the chart automatically shows that the animal is possibly a crossbred.
I can tell you that many of the data results that I have seen have NAD cattle that are under less than 9.9% Unexplained, regardless of the percentages of OP, or NAD in those animals. I can also tell you that many of the NAD cattle also show more than 9.9% Unexplained, including animals that were born after the 2010 requirement by the AHA to have very walking herd bull parent verified in order for the breeder to be able to register calves from that bull. Parent verification does NOT guarantee breed purity. Breed percentage testing will.
Not only are NAD cattle that were born in North America having difficulties with high percentages of Unexplained, but there are modern day animals that have been imported into North America that have high percentages of Unexplained as well. What makes this interesting is the fact that some of the imported animals don’t necessarily have a lot of actual North American breeding in their pedigrees. This means that not only are breeders in North America vulnerable to Unexplained genetics from breeders at home, but also from the Unexplained genetics of imported cattle.
I hope that every Hereford Breeder, and every Hereford Breed Association/Society reads the Report, and takes it seriously. I also hope that Breeders decide to make use of the HTOPP test. Regardless of everyone’s difference of opinion of what type or combination of Hereford they want to raise, the test is an important and useful tool that will instantly tell the Breeder where their herd is going genetically.
herefordhbi.com will be offering the test to breeders from North America, the UK, and Australia through HHBI and the labs of Neogen. It may be that it will also be possible to send samples from South America by way of Neogen in Brazil, but this has not yet been tried, or set up. The test is now being offered on the HHBI website, and the main components are now in place. There may be some delay at the beginning, as details such as payment options and a few other small details are being attended to at this time, so if you are interested in trying the test please be patient, it is a new system.
Have a good day,
