PURPOSE: A producing method of rumen-protecting choline for producing choline-fortified milk, and the rumen-protecting choline are provided to prevent the decomposition of a choline component in rumen of milking cow. CONSTITUTION: A producing method of rumen-protecting choline for producing choline-fortified milk comprises the following steps: fixing a choline solution on a fixing carrier, and removing the moisture to obtain choline fixed to the fixing carrier; mixing the choline fixed to the fixing carrier with a first binding/coating agent for coating, and extruding to obtain firstly coated choline; inserting the firstly coated choline in a rotating drum-type coating machine, and coating with a second binding/coating agent to obtain secondly coated choline; cooling the secondly coated choline at 40 deg C; and inserting the secondly coated choline in the rotating drum-type coating machine, and coating with the second binding/coating agent to obtain thirdly coated choline. |
