Anthocyanidin disease-resistant soft-shelled turtle feed and preparation method thereof

The invention discloses anthocyanidin disease-resistant soft-shelled turtle feed prepared from raw materials in parts by weight as follows: 100-110 parts of trash fish meal, 50-60 parts of wheat starch, 70-80 parts of peas, 60-70 parts of quinoa and the like. According to the disease-resistant soft-shelled turtle feed, purple sweet potato skins and grape skins are added, waste is fully utilized, environmental protection is facilitated, and those skins are rich in anthocyanidin, are matched with extracts of grape seeds, notoginseng flowers, spikenard and the like, have the disease resistance effect on growth of soft-shelled turtles and can help digestion, increase the food intake of the soft-shelled turtles and increase the yield; pig bone paste fermented with selenium-rich Bacillus subtilis and selenium-rich Lactobacillus plantarum is adopted, the content of functional substances such as polypeptides, amino acid, soluble calcium and the like in the pig bone paste is increased, enrichment of organic selenium is realized, and more nutrients are released for growth of the soft-shelled turtles.
