After a small sampling from one herd, it appears that the Dexter breed does have this highly inheritable genetic marker. It appears that the marker is found in those cows with the most milk production. This makes total sense, as they refer to the genetic marker as found in most easy keeping cattle.
Unfortunately no bulls were part of the initial testing and semen is not able to be tested for this marker.
So, now that we know the marker is there for the Dexter breed and that it seems to be in cows with most milk…we need more folks to test. It has been suggested that it maybe easy to get a few drops at ear tagging time and a simple tail stick for the older ones.
If you would like more information on how to get your herd tested, please reach out to the Irish Dexter Cattlemen and we will help you get started. It requires only a few drops of blood on a Tenet card sampler. The card is then sent of for sequencing.
It takes 5 days to get to the lab and 10-30 days for the sequencing to happen after being received. They send your your results by email. Pretty simple procedure.
The thing that was most interesting was it was found in the cows with the most milk production. How cool would it be to be able to predict possibly milk production and beef tenderness? Duality!
In case, you need to brush up on this. Below is the podcast that started this adventure. This is NOT the Neogen testing that has been happening by a group of Dexter breeders.
