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.
