Beef heifers were fed during late pregnancy to produce cows in poor, average, and good condition at calving late in winter. The animals were fed on dry-lot for the major part of the experiment. At 50 days of age half the calves were removed from their dams for 7 days, but no cows were induced to ovulate. The remaining calves were temporarily weaned for one week at 80 days of age. Only two cows exhibited oestrus shortly after calf removal.
