The present invention relates to animal feed additives containing rare earth elements and a manufacturing method thereof. The animal feed additives are manufactured through a cultivation step and a drying step after additionally mixing water to a rare earth element mixture consisting of rare earth element compound, chitosan liquid, citrate powder, concentrated mineral, rice bran, corn powder, zeolite, molasses, and complex microorganisms. Therefore, according to the present invention, by allowing livestock to intake the feed additives, it is possible to improve immunity through toxin gas removal and diarrhea prevention of the livestock, and at the same time, to reduce bad smell in a shed, thereby improving an environment of the shed. Also, a temperature condition, in which a temperature is gradually raised from an initial 40 degree setting temperature to a final temperature of 55 degrees for 48 hours, is applied to the cultivation step, thereby improving preference such as flavor and the like through a Mailard reaction in the cultivation step so as to improve efficiency of feed. Further, by containing the rare earth element compound and the chitosan liquid, it is possible to improve meat quality and meat color of livestock, and to improve immunity by allowing livestock to intake the feed additives, thereby maximizing disease prevention efficiency of the livestock.(S110) Mixture preparation step of preparing a rare earth element mixture(S120) Additional mixing step of adding 40 parts by weight of water with respect to 100 parts by weight of the prepared rare earth element mixture(S130) Cultivation step of cultivating the rare earth element mixture added with water for 48 hours at a specific temperature condition(S140) Drying step of drying feed additives which is completed with cultivation through mixture preparation, additional mixing and cultivation processesCOPYRIGHT KIPO 2019
