A fast-acting bolus that provides an industry-high 44 grams of available calcium from calcium propionate, calcium chloride and calcium carbonate to deliver both rapid and sustained release of this important mineral. Unlike other calcium boluses, which can take hours to begin delivering calcium to the bloodstream, the Triple Calcium Bolus begins its release immediately. Whether used as supportive treatment or a preventive measure, this innovative bolus is designed to make it easy for producers to supplement cows with the calcium they need to maintain health at calving.
