The invention belongs to the field of agricultural breeding, and particularly relates to
animal feed processed by the aid of
ginkgo biloba sarcotesta and a method for preparing the
animal feed. The
animal feed processed by the aid of the
ginkgo biloba sarcotesta is made of the
ginkgo biloba sarcotesta. The method includes repeatedly extracting the
ginkgo biloba sarcotesta by the aid of organic solvents to remove
ginkgolic acid which is a toxic substance in the
ginkgo biloba sarcotesta; centrifugally washing the
ginkgo biloba sarcotesta to remove the residual organic solvents to obtain the animal feed. The animal feed and the method have the advantages that the residual quantity of the
ginkgolic acid in the animal feed made of the ginkgo biloba sarcotesta is lower than 10 mg / kg, and the residual quantity of the organic solvents is lower than 0.5 wt%; the ginkgo biloba sarcotesta contains abundant
starch, polysaccharides,
amino acid, diversified vitamins and proteins, further contains small quantities of ginkgo flavone,
terpene lactones,
daucosterol and diversified trace elements and is processed to obtain a ginkgo biloba sarcotesta
feed additive, the ginkgo biloba sarcotesta
feed additive can be used for breeding animals, and accordingly effects of preventing and treating diseases, protecting health and promoting growth of
livestock can be realized; food can be saved, environments can be cleaned,
pollution can be reduced, and requirements of the modern breeding industry on environmental friendliness,
environmental protection, safety and zero
pollution can be met.
