Embodiment 1

[0025] A crayfish growth-promoting feed is composed of the following raw materials in parts by weight: 70 parts of fermented soybean meal, 20 parts of peanut powder, 30 parts of water hyacinth, 20 parts of animal offal, 5 parts of phospholipid oil, 3 parts of cod liver oil and 1 part of multivitamin.

[0026] The animal viscera is made by crushing fish intestines, chicken intestines and pig lungs and mixing them.

[0027] The weight percent of each component in the multivitamin is as follows: vitamin A accounts for 20%, vitamin B1 accounts for 15%, vitamin B2 accounts for 15%, vitamin C accounts for 20%, and vitamin D3 accounts for 20%.

[0028] After the above-mentioned raw materials are proportioned, they are crushed and mixed so that 100% of the fineness passes through 80 mesh and more than 95% passes through 100 mesh to prepare the crayfish growth-promoting feed.

Embodiment 2

[0030] A crayfish growth-promoting feed is composed of the following raw materials in parts by weight: 90 parts of fermented soybean meal, 30 parts of peanut powder, 50 parts of water peanut, 30 parts of animal offal, 8 parts of phospholipid oil, 6 parts of cod liver oil and 3 parts of multivitamins.

[0031] The animal viscera is made by crushing fish intestines, pig lungs, pig liver and pig belly and then mixing them.

[0032] The weight percent of each component in the multivitamin is as follows: vitamin A accounts for 30%, vitamin B1 accounts for 10%, vitamin B2 accounts for 20%, vitamin C accounts for 15%, and vitamin D3 accounts for 25%.

[0033] After the above-mentioned raw materials are proportioned, they are crushed and mixed so that 100% of the fineness passes through 80 mesh and more than 95% passes through 100 mesh to prepare the crayfish growth-promoting feed.

Embodiment 3

[0035] A crayfish growth-promoting feed is composed of the following raw materials in parts by weight: 80 parts of fermented soybean meal, 25 parts of peanut powder, 40 parts of water hyacinth, 25 parts of animal offal, 6 parts of phospholipid oil, 4 parts of cod liver oil, and 2 parts of multivitamins.

[0036] The animal viscera is a combination of three or more of pig heart, pig lung, pig intestine and pig liver, which are crushed and mixed.

[0037] The weight percent of each component in the multivitamin is as follows: vitamin A accounts for 27%, vitamin B1 accounts for 13%, vitamin B2 accounts for 18%, vitamin C accounts for 19%, and vitamin D3 accounts for 23%.

[0038] After the above-mentioned raw materials are proportioned, they are crushed and mixed so that 100% of the fineness passes through 80 mesh and more than 95% passes through 100 mesh to prepare the crayfish growth-promoting feed.
