Eucommia ulmoides leaf-wormwood compound fermentation product feed additive as well as preparation method and application thereof

The invention belongs to the technical field of microbial fermentation Chinese herbal medicine feed additives, and particularly relates to a folium cortex eucommiae-wormwood compound fermentation product feed additive as well as a preparation method and application thereof. The prepared folium cortex eucommiae-wormwood compound ferment feed additive is obtained by fermenting folium cortex eucommiae and wormwood serving as fermentation substrates through a compound bacterium suspension, and after the folium cortex eucommiae and the wormwood are subjected to synergistic fermentation through lactobacillus plantarum, enterococcus faecalis and saccharomyces cerevisiae in the compound bacterium suspension, the nutritional value is further increased; the feed additive is added into a basal feed as an additive, can promote the digestion and absorption rate and the feeding rate of animals, further improves the utilization rate of the feed, is applied to laying hen breeding, remarkably reduces the cholesterol content o
