The invention is solid compositions comprising feed-grain calcium phosphates surface-coated with a mixture of molasses and a surfactant, wherein the compositions are characterized by having substantially reduced dusting properties as compared to similar but uncoated products. The invention further relates to a process for coating feed-graide calcium phosphates with a mixture of molasses and a surfactant to minimize dusting of the products.
