The present invention discloses a fluoroethyl thiamine or salts thereof and application thereof in preparation of anticoccidial drugs. The structural formula of the fluoroethyl thiamine or salts thereof is shown as Formula (I). The fluoroethyl thiamine or salts thereof of the present invention have a remarkable anticoccidial effect, particularly on some coccidia which had resistance to other anticoccidial drugs, therefore the fluoroethyl thiamine or salts thereof of the present invention can be applied to preparation of anticoccidial drugs. Thus, the present invention provides conditions for development of new anticoccidial drugs.
