Embodiment 1
[0017] Follow the steps below to prepare grouper compound feed:
[0018] S1. Weigh the raw material components according to the following mass percentages and mix them evenly: 40% white fish meal, 6% squid meal, 10% Antarctic krill meal, 13% peeled soybean meal, 10% gluten powder, 10% high-gluten flour, Calcium dihydrogen phosphate 0.5%, fish oil 4%, soybean oil 2%, liquid phospholipid 2%, Bacillus 0.15%, glyceryl butyrate 0.35%, vitamin premix 1%, mineral premix 1%; The raw material components are all commercially available raw materials;
[0019] S2. After mixing all raw materials evenly, pass through a superfine pulverizer, so that all raw material components can pass through a 200-320 μm sieve;
[0020] S3. Transfer the material in the step S2 into the modem, feed in steam at 90-95°C for 5-7 minutes, and then carry out extrusion granulation at a temperature of 80-95°C;
[0021] S4. Dry the feed pellets at 85-90° C., then pack them into bags after cooling.

Embodiment 2
[0024] S1. Weigh the raw material components according to the following mass percentages and mix them evenly: 37% white fish meal, 11% squid meal, 8% Antarctic krill meal, 16.5% peeled soybean meal, 8% gluten powder, 8% high-gluten flour, Calcium dihydrogen phosphate 0.8%, fish oil 3.5%, soybean oil 2.5%, liquid phospholipid 2%, Bacillus 0.25%, glyceryl butyrate 0.45%, vitamin premix 1%, mineral premix 1%; The raw material components are all commercially available raw materials;
[0025] S2. After mixing all raw materials evenly, pass through a superfine pulverizer, so that all raw material components can pass through a 200-320 μm sieve;
[0026] S3. Transfer the material in the step S2 into the modem, feed in steam at 90-95°C for 5-7 minutes, and then carry out extrusion granulation at a temperature of 80-95°C;
[0027] S4. Dry the feed pellets at 85-90° C., then pack them into bags after cooling.
[0028] From May 18 to September 18, 2014, experiments were conducted on the...
