摘要： A fertilizer supplying animal nutrients including a core particle having an outer surface and comprising compounds containing animal nutrients, and a coating of urea on the outer surface of the core particle, and further a process of making the fertilizer including the steps of: screening animal nutrient core particles comprising a powdered substance containing an animal nutrient, to a preselected particle size; spraying melted urea onto the surface of the nutrient core particles to produce a coating on the nutrient core particles; granulating the nutrient core particles with sprayed melted urea to produce nutrient core granules; and cooling the nutrient core granules.
