Division of Sexing Technologies, the source of "sexed Ultra" gender sorted semen
The company focus is on Holstein, Brown Swiss and Jersey sires (the three largest breeds worldwide)
However, they also offer Guernsey, MIlking Shorthorn, Ayrshire and HOxJE cross selections, as well as a few "Beef on Dairy" crossing options.
ST has two company employed salespeople in Michigan, as a result we handle ST sires as a "special order" option.
They have a separate division for BEEF sires of interest to Beef breed cattlemen. We have not explored that yet.
