Which mineral is best for 7 months old pregnant cow

For a seven month pregnant cow, a good cattle mineral mixture is the best choice. Give a trusted mineral mixture made for dairy cows, along with clean water and balanced green fodder, dry fodder, and enough energy feed. Do not overfeed calcium now. In the last two months before calving, the mineral support becomes even more important. If she is weak, off feed, or has swelling, get her checked. Consult a veterinarian before administering any medicine or treatment.
