  1. aTwo farms with missing values for the TI fattening pigs
  2. bThe treatment incidence is defined as the number of pigs per 1000 pigs that receive a daily dose of antimicrobials. A TI 200 days is applied for pigs from birth till slaughter for comparison between herds, assuming an expected lifespan of 200 days
