PURPOSE:A feed additive, obtained by granulating a mixture containing calcium carbonate and a specific material, and capable of passing through the rumen of ruminants and dissolving out satisfactorily in the abomasum or thereafter. CONSTITUTION:A feed additive containing a material effective for living bodies. The feed additive is obtained by adding (a) >=20wt% calcium carbonate to (b) >=10wt% at least one substance of a >=14C straight chain or branched saturated or unsaturated monocarboxylic acid or a salt thereof or a wax having >=40 deg.C melting point, and granulating the resultant mixture. The above-mentioned material effective for the living bodies is a nutriment or a feed or drug containing the same, and preferably absorbed through the abomasum or thereafter effectively in the bodies of individual ruminants without consumption by microorganisms in the rumen. Examples of the material include amino acids, proteins, vitamins, veterinary drugs, hormones, etc. |
