Provided are a dispersion-type feed additive composition for ruminants containing 40% by weight or more but less than 65% by weight of a basic amino acid which is a biologically active substance; and a method of producing the same, that is, granules which have rumen bypass properties, can release the biologically active substance at a high concentration in the small intestine of a ruminant animal to thereby increase the milk yield of a lactating cow and can be shaped into an arbitrary form being hardly classified when added to a feed; and a method of continuously producing the above-described granules at a high efficiency. A feed additive composition for ruminants which contains at least one protective agent selected from a hardened vegetable oil and a hardened animal oil having a melting point higher than 50oC but lower than 90oC, 0.05 to 6% by weight of lecithin, water and 40% by weight or more but less than 65% by weight of a basic amino acid; and a method of producing the feed additive composition for ruminants characterized by comprising solidifying a molten mixture, which comprises at least one protective agent selected from a hardened vegetable oil and a hardened animal oil having a melting point higher than 50oC but lower than 90oC, lecithin and a basic amino acid, by dipping the same in water. |
