A molasses-based liquid animal feed supplement including a nutritionally appropriate phosphorus content is hardened into a solid form by the addition of a small amount of a soluble calcium compound, e.g., calcium chloride. The disclosed solid animal feed supplement is sufficiently palatable to permit its free choice feeding and contains sufficient molasses to help meet the energy requirements for maintenance and weight gain of grazing animals. The solid animal feed supplement is prepared by mixing the ingredients to provide a solution having a critical pH, in the range of from 2.7 to 4.5, to permit the in-situ reaction of an orthophosphate compound and a calcium compound. Within this critical pH range, the solution quickly hardens into a solid molasses block having a hardness of 80 or less (i.e. in 0.1 mm Penetrometer units). To avoid requiring excess calcium ion to effect hardening, the ingredients are, preferably, mixed in the absence of added sulfate ion and calcium sequestrants.
