In the present invention, talc, when mixed with the particulate matter, adheres to the surface of the particulate matter to prevent direct contact between the particulate matter and to reduce frictional resistance between the particulate matter. As a result, the solidification of feed additives is prevented. It is presumed that these effects are due to talc having an appropriate hardness and particle size.
