When calcium chloride was added to a mixture of minerals and urea in molasses, the minerals had not settled after the mixture was shipped 350 miles and stored 4 weeks. Calcium carbonate added to a similar supplement caused all minerals tested except sodium, potassium, and copper to precipitate.
Using a 112-day, steer-feeding trial, we found that animals performed similarly when their liquid feed supplement contained either calcium chloride or resuspended calcium carbonate.
