The invention relates to a through-rumen choline chloride microcapsule and the preparation technique thereof, and solves the problems that choline chloride has a poor effect through the rumen, ruminants have a low intestinal absorption rate and packing, storage and transportation are not easy. The technical proposal is as follows: choline chloride with a mass percentage of 35 to 40 percent is adopted as the main active ingredient and used as the core material, acrylics IV is used as the internal coating of the core material, chitosan is used as the external coating, and the mass of the internal and external coatings is both 3 to 5 percent of the mass of the core material. The through-rumen choline chloride microcapsule can guarantee that a good moisture resistance is ensured during packing, storage and transportation, deformation and damage fail to occur due to compression, the goal of a slow release can be achieved in the rumen and the intestinal absorption rate of choline chloride is improved. |
