Sexed semen has been used in the dairy industry since 2005. In the beginning, the technology helped large commercial dairies to increase the number of heifer replacements. With the revenue now available by selling calves for the beef market, STgen Central U.S. Sales Lead Eric Zwiefelhofer says the focus has shifted. “As time has gone on with improvements in technology, we’re really dialing in heifer inventories to make sure we’re creating the right number of heifers that we need for the dairy, we’re able to produce those black calves on the back end, and that is driving a lot of profit in dairies right now.” STgen is promoting fresh gender-sorted semen for higher conception rates.
