An acidic molasses-based liquid animal feed supplement stock including calcium and mangesium, so that the calcium to magnesium weight ratio is between about 1.5 and 3, and, optionally, non-protein nitrogen, is hardened into a solid form by the addition of a phosphorus-containing compound in a nutritionally appropriate amount. In the preferred embodiment a single homogeneous first solution containing the sugar or molasses and the soluble calcium and magnesium compound but containing no added phosphorus compound is prepared and stored until it is desired to manufacture the animal feed blocks. At that time a second solution containing phosphorus but no calcium, magnesium, or molasses is added to the first solution so that the blocking reaction can occur.
