An amino acid feed additive is obtainable by a process comprising mixing a granular feed additive containing from 30 to 90% by weight, on the dry basis, of amino acid(s) with fine particles of a caking preventive selected from the group consisting of silica gel, sucrose fatty acid ester, glycerin fatty acid ester, branched amino acid, calcium salt, magnesium salt, aluminum silicate, magnesium oxide, alumina, zeolite, talc, diatomaceous silica, perlite, disodium hydrogen phosphate and mixtures thereof, the mixing ratio of which is from 0.1 to 5% by weight to the granular feed additive. The granular feed additive used as a starting material may be produced from a fermentation broth comprising amino acids. By mixing the granular feed additive mainly comprising amino acids with a small amount of a caking preventive it is possible to suppress caking due to moisture absorption and the obtained feed additive has excellent flowability and is convenient to use and to store. |
