Abstract

Disclosed is a use of a diaminoguanidine derivative and a feed composition thereof in the preparation of a veterinary drug. Particularly, disclosed is a use of a diaminoguanidine derivative having a structure of formula (I), or a stereoisomer, geometric isomer, tautomer, solvate, pharmaceutically acceptable salt thereof, or a prodrug thereof, in the preparation of an animal drug for preventing, managing, treating, or alleviating a disease resulting from bacterial infection, wherein R is NO, or a group represented by formula (II) or formula (III); Ris a linear or branched C-Calkyl group; A is O, NH or S; Ris a linear or branched C-Calkyl, C-Ccycloalkyl, C-Caryl or CH(C-Caryl) group. The diaminoguanidine derivative is a non-toxic and safe compound for animals, and is markedly effective in the treatment of infectious diseases in the reproductive system, skin, etc., of farmed animals.
