Preparation method of folium ginkgo biological feed additive

Abstract

The invention discloses a preparation method of folium ginkgo biological feed additive. Solid fermentation is conducted under appropriate nutrient conditions and cultivation conditions with folium ginkgo as the main solid fermentation matrix and aspergillus niger as the bacterial strain, and the biological feed additive is obtained after drying and smashing; the biological feed additive contains various bioactive substances such as flavonoids compounds, and the organism immunity and oxidation resistance of animals can be improved. Meanwhile, the nutritional value and biological activity of the biotransformed product are greatly improved, and therefore a foundation is laid for deep research and development of the composite multifunctional folium ginkgo biological feed additive.

Description

technical field

[0001] The invention belongs to the technical field of biological feed development, and in particular relates to a preparation method of a ginkgo biloba biological feed additive. Background technique

[0002] Ginkgo biloba L. is a special fruit tree and garden plant in my country. Ginkgo is not only edible, but also medicinal. Ginkgo biloba contains a large amount of flavonoids, and its medicinal functions are mainly to treat coronary arteriosclerosis, cerebrovascular disease, angina pectoris, lower cholesterol, lower blood pressure, and inhibit certain bacteria and fungi. At present, there have been many reports on the development and utilization of ginkgo at home and abroad, such as ginkgo tea, ginkgo drinks, and ginkgo health products. With the improvement of consumers' requirements for the quality of animal products, the application of chemical feed additives such as hormones for disease prevention and growth promotion and antibiotics that are prone to ...
