PURPOSE: To produce a feed additive having excellent storage stability even in a state that the additive is mixed with feed by coating the feed additive and more particularly the feed additive contg. zinc bacitracin by an air control granulation system. CONSTITUTION: The coating is formed on the feed additive and more particularly the feed additive contg. the zinc bacitracine by using the air control granulation system using coating materials selected from 2.5 to 30wt.% physiologically harmless polymer and inorg. shaping material, for example, coating materials, such as, preferably, hydroxypropyl methylcellulose, carboxymethyl cellulose sodium, hydroxyethyl cellulose, methyl cellulose, in accordance with a starting material. |
