Abstract

The present invention discloses a novel river crab feed containing marine-derived active peptides. The prepared river crab feed consists of the following raw materials in weight percentages: 20-30% ofsoybean meal, 13-18% of peanut meal, 3-6% of protein peptide powder, 20-25% of fish meal, 6-10% of meat meal, 3-5% of squid paste, 18-25% of flour, 3-5% of shrimp powder, 4-8% of yeast powder, 2-5% of fish oil and 1.8% of monocalcium phosphate. The present invention also relates to a preparation method of the feed. The novel river crab feed can improve digestibility, immunity and disease resistance, and at the same time has advantages of being good in water stability and reducing water pollution.

Description

technical field [0001] The invention relates to the field of aquaculture feed processing, in particular to a novel river crab feed added with marine-sourced active peptides; the invention also relates to a preparation method of the feed. Background technique [0002] The scientific name of river crab is "Chinese mitten crab", which is a kind of crab that grows in fresh water and breeds in river water. According to the growth characteristics of river crabs, its growth stages can be divided into five stages: egg-bearing crabs, river crab larvae, juvenile crabs, middle crabs and adult crabs. River crabs have only one reproductive cycle in their lifetime. Generally speaking, the lifespan of river crabs is 1-3 weeks old. River crab is a special product of rivers and lakes in coastal areas of my country. In my country's crab breeding production, river crabs have the largest breeding area and the largest output. At present, the vast majority of crab farmers in our country feed ...
