Example Embodiment

[0023] Example 1:

[0024] The weight percentage composition of each raw material component of the compound feed:

[0025] Fermented rapeseed meal 15%, fermented soybean meal 25%, fish meal 7%, wheat 20%, chicken meal 8%, distillers grains 15%, calcium dihydrogen phosphate 2%, fish oil 4%, vitamin premix 2%, mineral premix Mixing 2%.

[0026] Wherein, the mineral premix contains 12g of iron citrate, 25g of zinc sulfate heptahydrate, 10g of potassium iodate, 20g of manganese sulfate monohydrate, 3g of potassium chloride, 40g of copper sulfate pentahydrate, and selenite per 1kg. 15g of sodium, 0.5g of manganese sulfate heptahydrate, balance of zeolite powder.

[0027] The preparation steps of compound feed:

[0028] 1) Weigh all raw material components and mix them evenly.

[0029] 2) Use an ultrafine pulverizer to pulverize the mixed raw material components described in step 1) until all the components can pass through a 350μm screen;

[0030] 3) Move the pulverized components described in step 2) into a modulator, pass in water vapor at 100°C for 3 minutes, and then extrude and expand at a temperature of 100°C;

[0031] 4) Dry the feed pellets at 85℃;

[0032] 5) Cooling and packaging the dried pellet feed in step 4).
