Embodiment 1
[0033] The feed additive of the present embodiment, preparation process is as follows:
[0034] (1) Mechanically separate the fresh distiller's grains after drying, remove the rice husk by grading and sieving, and then pulverize and pass through a 100-mesh sieve;
[0035] (2) Dehull the corn kernels and crush them into corn dregs, extrude the corn dregs in an extrusion extruder, during the puffing process, the screw speed of the extruder is 150rpm / min, the processing temperature is 140°C, and the expansion rate is 15% , then carry out secondary pulverization, and pass through a 100-mesh sieve to obtain puffed corn flour;
[0036] (3) activating Bacillus subtilis with a liquid medium and subcultured for 2-3 generations to prepare a Bacillus subtilis seed liquid;
[0037] (4) Mix the processed distiller's grains with puffed corn flour in a mass ratio of 8:2; mix manganese sulfate, magnesium sulfate and dipotassium hydrogen phosphate in a mass ratio of 1:4:5 to form metal ion in...
Embodiment 2
[0041] The feed additive of the present embodiment, preparation process is as follows:
[0042] (1) Mechanically separate the fresh distiller's grains after drying, remove the rice husk by grading and sieving, and then pulverize and pass through a 100-mesh sieve;
[0043] (2) Extrude corn gluten powder in an extrusion extruder. During the expansion process, the screw speed of the extruder is 150rpm / min, the processing temperature is 140°C, and the expansion rate is 15%. Mesh sieve to obtain puffed protein corn flour;
[0044] (3) activating Bacillus subtilis with a liquid medium and subcultured for 2-3 generations to prepare a Bacillus subtilis seed liquid;
[0045] (4) Mix the processed distiller's grains with puffed corn flour in a mass ratio of 8:2; mix manganese sulfate, magnesium sulfate and dipotassium hydrogen phosphate in a mass ratio of 1:4:5 to form metal ion inorganic salts, The addition amount is 80g / t; then the pH is adjusted to 6.0 with calcium hydroxide; it is...
Embodiment 3
[0049] The feed additive of the present embodiment, preparation process is as follows:
[0050] (1) Mechanically separate the fresh distiller's grains after drying, remove the rice husk by grading and sieving, and then pulverize and pass through a 100-mesh sieve;
[0051] (2) Dehull the corn grains and crush them into corn dregs, mix the corn dregs with the processed distiller's grains at a mass ratio of 2:8, and then extrude them in an extruder at the same time. During the extruder process, the extruder screw The rotation speed is 150rpm / min, the processing temperature is 140°C, the expansion rate is 15%, and then it is pulverized for the second time and passed through a 100-mesh sieve;
[0052] (3) activating Bacillus subtilis with a liquid medium and subcultured for 2-3 generations to prepare a Bacillus subtilis seed liquid;
[0053] (4) Mix manganese sulfate, magnesium sulfate, and dipotassium hydrogen phosphate in a mass ratio of 1:4:5 to form metal ion inorganic salts, ...
