Mixed feed for soft-shelled turtles

Abstract

The invention provides mixed feed for soft-shelled turtles. The mixed feed consists of the following raw materials in parts by weight: 30-35 parts of white fish meal, 5 parts of corn protein powder, 18-25 parts of pregelatinized starch, 5-10 parts of fermented soybean meal, 1-2 parts of monocalcium phosphate, 10-15 parts of micro marimo powder, 3-7 parts of beer yeast, 0.05-0.3 part of protease inhibitor, 0.2-0.5 part of choline chloride, 0.1-0.5 part of composite minerals, 0.1-0.3 part of composite vitamins and the balance of degreased brown fishmeal. The fixed feed has the beneficial effects that due to addition of the beer yeast and the micro marimo powder, the antioxidation function can be improved, the abuse of antibiotics can be reduced, and an excellent antioxidation effect can be achieved; with the combination of the corn protein powder, the white fish meal and the degreased brown fishmeal in the mixed feed, nutrient demands of the soft-shelled turtles to grow can be met, the cost can be lowered to a very large extent, protein can be provided to the feed from plant protein, the mixed feed is natural without additives, and the feed supply coefficient and the nitrogen and phosphorus discharge amount can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of aquatic product feed, in particular to a soft-shelled turtle compound feed. Background technique [0002] Soft-shelled turtle has the functions of nourishing and strengthening the body, prolonging life, and has high nutritional value. It is a traditional nourishing aquatic product in my country and has always been loved by the people of our country. With the rapid development of soft-shelled turtle aquaculture, the scale of aquaculture continues to expand, and it has become the main species of aquaculture in my country. At present, soft-shelled turtles are cultured mainly in greenhouses and ponds, but these two existing modes of soft-shelled turtle farming focus on the pursuit of output, and generally use high-protein soft-shelled turtle compound feeds and high-density farming, resulting in water in the cultured water. A large amount of excrement of soft-shelled turtles accumulates, the nitrogen and phosphorus con...

AI Technical Summary

Problems solved by technology

At present, soft-shelled turtles are cultured mainly in greenhouses and ponds. However, these two existing modes of soft-shelled turtle farming focus on the pursuit of output. Generally, high-protein soft-shelled turtle compound feed is used, and high-density farming is adopted, which leads to the loss of water in the cultured water. A large amount of excrement of soft-shelled turtles accumulates, the nitrogen and phosphorus content of the breeding water seriously exceeds the standard, the concentration of toxic substances such as nitrite and ammonia gas is too high, the water quality deteriorates, and the pollution is serious; soft-shelled turtles have lived in this water quality environment for a long time, and their physical fitness has seriously declined , the immune system has problems, resulting in frequent occurrence of soft-shelled turtle diseases, coupled with the frequent use of drugs, resulting in a vicious circle of poor water quality, frequent disease, and frequent use of drugs in soft-shelled turtle farming
