ABSTRACT:
Disclosed is a process for producing a composition for ruminants, which is characterized in that a nucleus containing a physiologically active substance is coated with a coating material prepared by suspending in water (i) an emulsion comprising water and at least one hydrophobic substance hardly soluble in water and (ii) a slurry containing at least one polymer soluble in water of pH 5.0 or below and insoluble in water of pH over 5.0 In the process, an aqueous suspension is used for coating instead of a meterial dissolved in an organic solvent.
