Abstract

The invention discloses a juvenile freshwater crayfish feed which is prepared from the following components: fermented soybean meal, wheat bran, sweet potato powder, rice bran, dried blood, minced fillet, monochoria vaginalis, alfalfa, water hyacinth, shell powder, beewax, complex vitamin, amino acid chelate, a Chinese herbal medicine additive and a composite additive. The feed disclosed by the invention contains comprehensive and balanced nutrition, and the varieties of raw materials are abundant; according to measurement, the protein content of the feed is over 35%, the fat content is 9-12%, the carbohydrate content is 18-20% and the vitamin content is 18-20%, thereby meeting the requirement for the proportion of nutrient substances for the growth of juvenile crayfish; and given the biting type mouthpart of the freshwater crayfish, which is different from the swallowing type mouthpart of fish, the feed is specially made into a strip shape or flake shape and has certain viscosity and is convenient to eat. Most of the raw materials of the feed are pure natural green raw materials, and the phenomenon of drug residue in crayfish bodies is avoided; and moreover, the yield can be remarkably increased, and relatively good culture benefits are created.
