For DHIA purposes you should register your Simmental/Fleckvieh (with Standard Breed Code in the registered name as the first code field) with the Red & White Association as well as with the Breed Association.  

As with all breeds, since the polled gene has become a rare gene in dairy cows, because of the failure to repeat the genes of the horned (ox) family lines, we need to have at least 10 elite cow Sponsors who will flush their cows to top polled bulls to create the bull mothers of the future. We also need 100 member sponsors for each bull of the breed who will raise polled animals to create proofs for the families and to provide a nucleus for further choices. Picking top polled cows is important, and to do that we need to have as many cows bred polled to produce the next generation as possible. If you can contribute cows, heifers, and recipients for these projects, please register and let us know what you can contribute. 

Please also identify the breed's Dairy polled females with their records if they are elite cows or offspring of an elite animal.

In a few short years the USA Simmental beef herd is about 2/3 polled. A cross with Holstein produces high milk producers. These can be registered in both the Simmental Association and with the Red & White Association Much of this is due to crossing with black angus, but much also is due to selection of homozygous polled Simmental sires and dams which are partly identified here.  Bavarian, Austrian and Swiss Fleckvieh are dual purpose cattle with some milk.

There are many homozygous polled Simmental / homozygous polled Fleckvieh Use these terms on your browser to locate other sources near you. Crossing the homozygous polled Simmental/Fleckvieh with Holstein was not popular in Switzerland, but the cows do milk!

Crosses are registered in the Red and White Dairy Cattle Association for DHIA testing and removed if the particular animalís milking ability falls short the Red Holstein. The cows can be registered also with the Simmental Association as an upgrade.
