Summary
Sexed semen is now used for the first two inseminations in heifers, with any subsequent services reverting to beef semen: “My primary focus is to ensure we’re getting five or six heifers pregnant with female calves each week. Compared to life without SenseHub, we’re moving heifers in and out of the dome shed far more quickly than I imagined,” Philippa says.
