Crayfish feed

Abstract

The invention relates to the technical field of aquaculture, and in particular relates to a crayfish feed which is prepared from the following raw materials in parts by weight: 20-25 parts of corn flour, 12-15 parts of soybean cake, 5-6 parts of wheat middling, 8-10 parts of wheat bran, 3-4 fish intestine powder, 2-3 parts of clam worm powder, 3-4 parts of freshwater shrimp powder, 5-6 parts of fresh soybean milk, 4-5 parts of pondweed, 2-3 parts of bone meal, 3-4 parts of fermented duck blood powder, 5-6 parts of alternanthera philoxeroide stem and leaf, 4-5 parts of bread crumb, 2-3 parts of sleeve-fish powder, a proper amount of salt and 4-5 parts of phagostimulant. The feed provided by the invention is completely accordant with the omnivorous characteristics of crayfish and contains multiple high-quality protein raw materials, the palatability of the feed can be improved because of the fishy smell of the raw materials such as the fish intestine powder, the clam worm powder and the sleeve-fish powder, the food consumption of the crayfish is increased, the fed crayfish can grow and develop rapidly, the weight can be remarkably increased, and moreover, as the raw materials are all pure natural green raw materials, the problem of medicine residue is prevented, and the quality of crayfish is ensured.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a crayfish feed and a preparation method thereof. Background technique [0002] Crayfish is delicious and nutritious. It is a high-protein, low-fat healthy food. It is an important species of freshwater shrimp farming in my country. It has the characteristics of large market demand and high breeding benefits. There are many ways to breed crayfish species, such as single culture in ponds, continuous cropping of rice and shrimp, etc., no matter which farming method is adopted, in order to improve the breeding efficiency, the feeding and management links must be strengthened. The existing commercial feed contains a variety of hormone substances, resulting in crayfish. Drug residues, in order to improve the edible value of lobsters, the use of hormone drugs should be avoided, and nutritionally balanced and comprehensive feed should be prepared to promote the growth and development ...
