Abstract

A method for improving ginkgo leaf feeding palatability and increasing product bioactivity comprises the following steps: well mixing solid fermentation raw materials composed of ginkgo leaves, edible mushroom waste mushroom dregs, soybean meal and the like with a microbial nutrient salt solution, performing disinfection to obtain a solid fermentation base material; with microbe which produce beta-glucosidase as strains, performing expanding culture of the strains, inoculating the strains into the prepared solid fermentation base material for fermentation; after fermentation, drying and pulverizing the material; adding a scenting agent, well mixing to obtain the product. Application tests show that the feed additive of the invention has significant effect of growth promotion, disease prevention and disease resistance on livestock and poultry. The feed additive can significantly promote the growth of piglets and suckling pigs, has obvious effect on the control of diarrhoea diseases, can well improve the laying performance of laying hens and reduce cholesterol content of eggs, and has good prevention and adjuvant therapy effect on dairy cow mastitis.

Description

[0001] technical field [0002] The invention relates to a preparation method of a feed additive and its products, in particular to a feed additive which uses ginkgo biloba leaves, waste edible fungus residues and soybean meal as main raw materials, uses microorganisms to ferment and transform them, and compound the fermented products and flavoring agents to obtain A method for a biological feed additive and a product obtained by the method. The invention also relates to the application of the product in aquaculture, belonging to the field of feed. [0003] Background technique [0004] In order to one-sidedly pursue breeding efficiency or to prevent and resist diseases and reduce the incidence of livestock and poultry in high-density breeding, farmers will use large doses of chemically synthesized growth promoters and antibiotics. These substances will remain in livestock and poultry products, enter the human body through the food chain, and cause a series of human disease...
