The Late Pregnant Heifer
A fourth heifer group is the springing heifer. Besides gaining 0.7 to 0.8 kg of growth (frame), she must also provide nutrients for a rapidly growing fetus. During late pregnancy, fetal and related tissue gains account for 0.6 to 0.7 kg per day of weight gain. Thus, the springing heifer should gain over 1.1 kg of scale weight per day (12). These heifers also need additional trace minerals and vitamins for the unborn calf and immune system.
