Abstract

The invention discloses a preparation method of a lactobacillus fermented ginkgo leaf feed additive and a product of the lactobacillus fermented ginkgo leaf feed additive. The ginkgo leaf feed additive is prepared by the following steps of mixing ginkgo leaves and dandelions according to a ratio of 5: 1, carrying out coarse crushing, ball milling crushing and colloid mill grinding to obtain a slurry, putting the slurry into a fermentation tank, performing sterilizing, cooling, inoculating a compound lactobacillus starter, carrying out slow fermentation at closed and low temperature, blending after fermentation, and performing homogenizing to obtain the ginkgo leaf lactobacillus feed additive with lactobacillus activity, or carrying out high-temperature sterilization to obtain the inactiveginkgo leaf lactobacillus feed additive. The preparation method is also characterized in that the solid ginkgo leaf lactobacillus feed additive with lactobacillus activity is prepared by adding a carrier for blending after fermentation and performing cold air drying, or the inactive solid ginkgo leaf lactobacillus feed additive is prepared by performing high-temperature sterilization, adding the carrier for blending and performing hot air drying after fermentation. The invention provides a new process for processing and utilizing the ginkgo leaves, provides a new nutritional feed additive forthe feed additive market, and enriches the varieties of lactobacillus preparations in the breeding industry.

Description

Technical field [0001] The invention belongs to the field of feed processing, and relates to a feed additive, in particular to a method for preparing a ginkgo biloba lactic acid bacteria feed additive prepared by lactic acid bacteria fermenting ginkgo biloba as a raw material and a product thereof. Background technique [0002] Lactic acid bacteria and its fermented products have a good effect on breeding animals. It has physiological functions such as improving the intestinal micro-ecological environment, inhibiting the reproduction and growth of spoilage bacteria, helping digestion, synthesizing nutrients, and improving immunity. [0003] At present, in the aquaculture industry, the application of lactic acid bacteria fermented feed additives is insufficient, and most of them are added to their pre-mixed feed or compound feed, resulting in poor product stability and unable to achieve the desired application effect. Shell powder, clay, calcium carbonate are still used. , Wheat br...
