PURPOSE:An animal drug, obtained by coating the surface of a granular pharmaceutical of an animal drug coated with a hydrophobic waxy material further with a water-soluble polymer, and used for oral administration by mixing in a feed, etc. CONSTITUTION:An animal drug pharmaceutical, obtained by coating an animal drub, e.g. antibiotic, sulfamide agent or nitrofuran based drug, with <=1pts.wt., particularly 5-50pts.wt., based on 100pts.wt. animal drug, hydrophobic waxy material, e.g. higher fatty acid, hardened natural fat or oil or natural wax, and coating the resultant granular pharmaceutical further with a water-soluble polymer, e.g. methyl cellulose, cellulose acetate or gelatin adjusted to preferably 2-5,000cps viscosity, capable of preventing the bitterness of the drug, and readily and orally administrable. If it is difficult to obtain the granular pharmaceutical, a nucleating agent, e.g. mica, talc or kaolin, for promoting crystallization of the animal drug may be incorporated with the hydrophobic waxy material to promote the crystallization.
