Preparation method and production equipment of special feed for channel catfish breeding

The invention discloses a preparation method and production equipment of a special feed for channel catfish breeding. The special feed for channel catfish breeding is prepared from the following raw materials in parts by weight: 2 to 3 parts of yolk immunoglobulin, 3 to 5 parts of sodium butyrate, 1 to 1.8 parts of an enzyme preparation, 0.3 to 0.5 part of herba houttuyniae, 0.2 to 0.8 part of propolis powder, 10 to 12 parts of vegetable protein, 13 to 15 parts of animal protein, 0.8 to 1.2 parts of an additive and 25 to 45 parts of water. The vegetable protein, the animal protein and the additive are arranged in the special feed for channel catfish breeding, so that the feed is rich in protein, the protein content is 55-60%, on the premise that the protein content is not increased, the yolk immunoglobulin, the sodium butyrate and the enzyme preparation are matched, the breeding speed of channel catfish can be increased, the nutritional value of the channel catfish can be guaranteed, the survival rate is guar
