Embodiment 1
[0027] Example 1 Rumen protected lysine 1
[0028] (1) Preparation of rumen protected lysine
[0029] ① Preparation of lysine granules
[0030] After mixing 480g of lysine hydrochloride, 60g of starch and 60g of microcrystalline cellulose, add appropriate amount of water to adjust to a state that can be granulated, prepare lysine granules with a diameter of 0.5mm with a granulator, and then use a spherical thrower to Shot blasting machine to get lysine pellets.
[0031] ②Drying of lysine granules
[0032] Put the lysine granules prepared in step ① into a fluidized granulation coating machine for drying. The heating temperature of the equipment is 85°C, the frequency of induced wind is 35Hz, the rotation speed is 45Hz, and the drying time is 30 minutes. Then sieve with 30-mesh and 40-mesh sieves respectively to obtain dry lysine granules of 0.40-0.60mm directly under the 30-mesh sieve and above the 40-mesh sieve.
[0033] ③ Coating of lysine particles

[0040] Example 2: Rumen protected lysine 2
[0041] (1) Preparation of rumen protected lysine
[0042] ① Preparation of lysine granules
[0043] Mix 400g of lysine hydrochloride, 50g of starch and 50g of microcrystalline cellulose, add water to make it ready for granulation, prepare lysine granules with a diameter of 0.5mm with a granulator, and then use a spherical shot blasting machine to prepare lysine granules with a diameter of 0.5mm. Shot blasting to get lysine particles.
[0044] ②Drying of lysine granules
[0045] Put the lysine granules prepared in step ① into a fluidized granulation coating machine for drying. The heating temperature range of the equipment is 85°C, the induced air frequency is 35Hz, the rotation speed is 45Hz, and the drying time is 30 minutes. Then sieve with 30-mesh and 40-mesh sieves respectively to obtain dry lysine particles with a diameter of 0.40-0.60 mm under the 30-mesh sieve and above the 40-mesh sieve.

[0054] Example 3 Evaluation of the bioavailability of rumen-protected lysine to lactating cows
[0055] In order to evaluate the bioavailability of the rumen-protected lysine products produced by the above method, three Holstein lactating cows with permanent rumen fistula were used as experimental animals, and the metabolic test was carried out by using a 3×3 Latin square design. Add the rumen-protected lysine 2 product (60 grams / head day) that adds the rumen-protected lysine 2 products (60 grams / head day) that the method of embodiment of the present invention 2 is produced in the ration to the influence of dairy cow digestion and metabolism and other main related indexes, so as not to add the rumen-protected lysine product as a control group. The main results of the test are shown in Table 3.
