The present invention an antibiotic-free fodder composition for domestic animals. According to the present invention, by adding germanium biotite instead of antibiotic to assorted fodder commonly used in the livestock industry, it is possible to produce domestic animals having a growth rate and immune ability as good as by adding a large amount of antibiotic to the feed. Therefore, in preparing feed, use of antibiotic harmful to animals and a human which has consumed the meat of the animals can be avoided partially or totally, thereby enabling production of "healthful meat". The present composition comprises a basal diet including corn, soybean meal, molasses, salt, vitamin premix and mineral premix, and 0.1 to 3.0% of germanium biotite including 36 ppm of germanium, and biotite, muscovite, feldspar, tourmaline, zircon, garnet, apatite and opaque minerals, and having 0.93% of emissivity and 4.3110² W/m² m of radioactive energy at a range of far infrared rays between 5 and 20 m.
