Environment-friendly nutritional type soft-shelled turtle feed and preparation method thereof

Abstract

The invention discloses a preparation method of environment-friendly nutritional type soft-shelled turtle feed. The method comprises the steps as follows: sweet potato flour, millet flour, royal jelly, fermented waste from slaughter houses, corn germ protein powder, silkworm chrysalises, spirulina powder, herba houttuyniae and an antibacterial halloysite compound are uniformly mixed, water is added, steaming under normal pressure is performed, concentration is performed, potato powder, taurine, chitosan and EM bacteria are uniformly stirred, and granulation and drying are performed, so that the environment-friendly nutritional type soft-shelled turtle feed is obtained. The antibacterial halloysite compound is prepared by the following technology: bamboo powder is added to a sodium hydroxide solution, stirring and filtration are performed, the obtained product is washed to be neutral, halloysite nanotubes and water are added, mixed grinding is performed, water is added, stirring and standing are conducted, a supernatant is taken, a Chinese herbal medicine additive is added, the obtained product is continuously stirred, and filtration and drying are performed, so that the antibacterial halloysite compound is obtained. The feed has rich nutrient substances, is easy to digest and absorb, can meet the growth requirement of soft-shelled turtles, has good suspension and adhesion properties, good water resistance and low loss rate and can reduce feces of soft-shelled turtles and reduce water pollution, so that the fatality rate of soft-shelled turtles is extremely low.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to an environment-friendly nutritious soft-shelled turtle feed and a preparation method thereof. Background technique [0002] Soft-shelled turtle has the function 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. Since the 1990s, soft-shelled turtle farming in my country has developed rapidly, and the scale of farming has expanded, becoming one of the main species of aquaculture in my country. [0003] At present, the culture of soft-shelled turtles mainly adopts pond culture, but this kind of soft-shelled turtle farming mode only pursues the output and the soft-shelled turtle culture output per unit of water body. It often uses high-protein soft-shelled turtle compound feed and excessive feeding, resulting in residual bait in th...

Problems solved by technology

[0003] At present, the culture of soft-shelled turtles mainly adopts pond culture, but this kind of soft-shelled turtle farming mode only pursues the output and the soft-shelled turtle culture output per unit of water body. It often uses high-protein soft-shelled turtle compound feed and excessive feeding, resulting in residual bait in the breeding water body and a large number of soft-shelled turtles. A large amount of excrement accumulates, the nitrogen and phosphorus content of the aquaculture water body 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
