Growth-promotion trionychidae feed and preparation method thereof

The invention discloses growth-promotion trionychidae feed. The growth-promotion trionychidae feed is prepared from raw materials in parts by weight as follows: 70-80 parts of duck visceral meal, 100-110 parts of potatoes, 130-140 parts of a saline solution, 65-70 parts of a chicken liquid, 55-65 parts of swine bones, 1-2 parts of selenium-enriched bacillus subtilis, 1-2 parts of selenium-enriched lactobacillus plantarum, 50-60 parts of green bean starch and the like. The potatoes are added to the growth-promotion trionychidae feed, the chicken liquid is used for seasoning, so that the feed has good palatability and rich nutrition and can promote trionychidae growth; herb residues such as kudzuvine roots and the like are added, residual nutrients of the herb residues are provided for trionychidae growth, and environmental protection is realized; with adoption of swine bone paste fermented by selenium-enriched bacillus subtilis and selenium-enriched lactobacillus plantarum, the content of functional substances such as polypeptide, amino acid, soluble calcium and the like in the swine bone paste is increased, enrichment of organic selenium is finished, and more nutrients are released to be provided for trionychidae growth.
