The invention discloses a bacillus polymyxa CPL258 as well as a screening method and application of the bacillus polymyxa CPL258. The bacillus polymyxa CPL258 is identified as the bacillus polymyxa and is preserved in the China Center for Type Microbiological Culture Collection, the preservation time is September 13, 2021, and the preservation number is CCTCC (China Center for Type Culture Collection) NO.M20211157. The invention further discloses a preparation method of the bacillus polymyxa CPL258. The bacillus polymyxa CPL258 is a gram-positive brachybacter bacterium capable of producing spores, can produce antibacterial peptides, nucleoside substances, antibiotics, antibacterial proteins and the like with bacteriostatic action, and has the effects of preventing and treating porcine diarrhea caused by animal Escherichia coli, thereby enhancing the immunity of piglets and reducing the death rate. In conclusion, the bacillus polymyxa CPL258 disclosed by the invention has a wide prospect in the aspect of pigle
