Table 1 Treatment incidence (TI = Number of animals treated daily with one animal daily dose (ADD) per 1000 pigs) of the active substances for all oral antimicrobials used during the 12 months prior to the investigation of farms. Data are presented for the case group (with oral group treatment of antimicrobials in at least 50 % of pigs) and the control farms (with no regular oral group treatment)
