The invention relates to the technical field of biology, in particular to preparation of swine lactobacillus plantarum fermentation liquor with antibacterial activity on various bacteria, and particularly relates to fermentation liquor containing swine lactobacillus plantarum JSMY-001 and folium cortex eucommiae polysaccharide. The JSMY-001 is separated from a healthy domestic pig, so that the JSMY-001 is more beneficial to field planting in a pig body. Researches show that the metabolite of JSMY-001 has certain antibacterial activity, and the addition of the folium cortex eucommiae polysaccharide into the culture solution of JSMY-001 can greatly promote proliferation and promote the production of the metabolite, generate a better synergistic effect and significantly enhance the antibacterial activity. The lactobacillus plantarum fermentation liquor can inhibit in-vitro proliferation of escherichia coli, staphylococcus aureus and streptococcus. The fermentation product can be developed and applied as a high-q
