Sep 08, 2015  Although pure (feed-grade) calcium carbonate is relatively inexpensive, there is another source of calcium that is even cheaper. That is limestone, which costs as little as EUR30 to EUR50 per metric ton. One would be excused to believe that such difference in price is not enough to bother, in the grand scheme of feed formulation.
