PURPOSE:A feed additive, obtained by adding a specific material to a water-insoluble salt of an acid, more weakly acidic then hydrochloric acid, and acceptable by living bodies as a main agent, and granulating the resultant mixturre, 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 is obtained by adding (a) >=20wt%, based on the total amount of the feed additive, water-insoluble salt of an acid, more weakly acidic than hydrochloric acid, and acceptable by the living bodies 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 throug the abomasum or thereafter effectively in the bodies of individual ruminants without consumption by microorganisms in the rumen. Calcium tertiary phosphate, magnesium tertiary phosphate, magnesium carbonated, etc. may be cited as the above-mentioned water-soluble salt. |
