         Sire selection should be a
      combination of visual eval-

      Live Calves
         Typically, calves born
      with assistance, such as
      hard pulls, have a high-
      er death and sickness rate
      than calves that are born
      unassisted. Three  prima-
      ry EPDs predict the ability
      of a sire’s calves to be born
      with unassisted delivery:
      calving ease direct (CED),
      birth weight (BW) and calv-
      ing ease maternal (CEM).
      Calving ease direct (CED
      EPD) predicts the percent-
      age of a sire’s calves that
      will be born unassisted, BW
      predicts the difference in
      weight of a sire’s calves and
      CEM predicts the percent-
      age of a sire’s daughters
      who will calve unassisted.
