PURPOSE: A feed additive containing activated humic substances, a chelated mineral-organic acid complex and a fermented biomass which forms antibiotics, digestive enzyme, biologically active substances(vitamins), growth promoting substances(hormones) or the like is provided which improves growth rate and meat quality of livestock and increases tolerance to diseases. CONSTITUTION: The feed additive comprising 20 to 50 parts by weight of activated humic substances containing mineral complexes of peroxyfulvic acid and other activated substances, 100 parts by weight of a chelated mineral-organic acid complex and 100 parts by weight of a fermented biomass is fed to a feed in an amount of 1 to 2% by weight. The mineral complexes are obtained by reacting mineral powder such as pegmatite, elvan, phyllite, oyster shell, zeolite, sericite, tourmaline, loess, coral fossil, aragonite or the like with citric acid, tartaric acid and fulvic acid.
