Anti-scattering feed formula for procambarus clarkii, and production method thereof

Abstract

The present invention relates to an anti-scattering feed formula for procambarus clarkii, and a production method thereof. A specific method is as follows: S1, raw materials are mixed: 30-35 parts ofanimal proteins, 45-50 parts of cereals, 10-14 parts of fruit and vegetable juice, 0.8-1.2 parts of white granulated sugar, 0.4-0.6 part of a shelling agent (cyanotis arachnoidea powder), 0.2-0.5 partof a binder and 0.2-0.4 part of a preservative are crushed, the crushed materials are stirred, and the stirred materials are mixed; the animal proteins comprise crushed chicken liver, crushed chickenheart, crushed egg yolk, silkworm chrysalis meal, fish meal, goat milk powder and shrimp powder; the cereals comprise soybean meal, peanut meal, rice bran, wheat flour, sweet potato powder, black sesame powder and bean paste; and the fruit and vegetable juice comprises the compositions of carrots, peppers, spinach, wax gourds, tomatoes and blueberries; S2, the mixture is subjected to a modified treatment; S3, the mixture is subjected to granulating; S4, the granules are subjected to a sterilization treatment; S5, the granules are cooled and shaped; S6, the granules are screened; and S7, the granules are packaged. The feed is free of chemical hormones to avoid a problem of food safety.

Description

technical field [0001] The invention relates to the technical field of feed formulations, in particular to an anti-collapse crayfish feed formulation and a production method thereof. Background technique [0002] Crayfish, also known as Procambarus clarkii, red crayfish and freshwater crayfish, have hard shells and long and narrow claws. The adult crayfish is about 5.6-11.9 cm long, the body is dark red, the carapace is almost black, and there is a wedge-shaped stripe on the back of the abdomen. Juvenile body is uniform gray, sometimes with black ripples. The middle part of the carapace of crayfish is not separated by mesh-like spaces, and the surface of the carapace has obvious grains. The forehead sword of crayfish has lateral spines or notches. Crayfish are freshwater economical shrimps, which are favored by people because of their delicious taste and rich nutrition. Because of its characteristics of omnivorous, fast growth and strong adaptability, it forms an absolut...

Problems solved by technology

[0003] Due to the large market demand for crayfish, in order to maximize profits in artificial breeding, a variety of chemical growth hormones are added to crayfish feed to promote the rapid growth of crayfish, thereby shortening the growth cycle of crayfish. It is difficult to be metabolized by crayfish in a short period of time, resulting in residual hormones in the body of crayfish, which will cause personal injury after human consumption
