<P>PROBLEM TO BE SOLVED: To provide a chicken feed mixing agent for demonstrating action and effect such as increasing iron content in eggs and lowering egg braking rate, to provide a method for producing the mixing agent, and chicken feed containing the chicken feed mixing agent. <P>SOLUTION: This chicken feed mixing agent contains an aqueous solution obtained by dissolving organic acid (such as citric acid) having carboxyl-base and/or hydroxyl-base, and FeO (FeO produced by a specific method and hard to oxidize), or a water removed product obtained by removing water from the aqueous solution. The method for producing the mixing agent comprises a dissolving process of heating a mixture containing powder of organic acid (such as citric acid) having carboxyl-base and/or hydroxyl-base, FeO powder (FeO powder produced by a specific method and hard to oxidize) and water, and dissolving the organic acid powder and FeO powder in water to bring into an aqueous solution. <P>COPYRIGHT: (C)2007,JPO&INPIT |
