Abstract

The invention discloses a crayfish feed suitable for various environments. The crayfish feed is composed of following raw materials in parts by weight: 33 to 48 parts of soybean meal, 6 to 14 parts ofcorn starch, 18 to 27 parts of peanut shell powder, 19 to 25 parts of corn protein powder, 13 to 22 parts of sorghum flour, 8 to 15 parts of bone meal, 2 to 8 parts of diatom powder, 8 to 14 parts offish meal, 7 to 13 parts of mung bean flour, 6 to 10 parts of shrimp meal, 8 to 14 parts of haw, 7 to 10 parts of pine needle, 11 to 18 parts of red bean, 12 to 17 parts of jujube, 8 to 14 parts of shredded vegetable leaves, 3 to 9 parts of soybean lecithin, 0.2 to 0.7 part of choline chloride, 1 to 4 parts of salt, 0.8 to 1.5 parts of fish oil, and 8 to 16 parts of water. The feed is made of multiple materials and is rich in proteins and multiple vitamins; the proportions of the nutritional ingredients are reasonable; the requirements of crayfishes on proteins, carbohydrates, crude fibers, and mineral substances can be satisfied; furthermore, the cost is low, the raw materials are easily available, the formula and preparation method are simple; the growth speed of crayfish is quick, theeffect on young and adult crayfishes is good, the disease incidence is reduced, and the feed is suitable for being used in various environments.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a crayfish feed suitable for various environments. Background technique [0002] Crayfish is a large edible shrimp in the world. It is delicious and nutritious, and is favored by people. With the continuous improvement of people's living standards, the consumption of crayfish is increasing day by day, and the market prospect is quite broad.
