  1. aA 728 sow farrow-to-finish farm with weekly farrowing batches was simulated to represent three different scenarios
  2. bScenario 1: a farrow-to-finish farm with prevalence of pleurisy < 25% and prevalence of lung scars < 8% with a wean-to-finish average daily gain (ADG) of 760 g and reaching target slaughter weight at 24 weeks of age
  3. cScenario 2: a farrow-to-finish farm with prevalence of pleurisy < 25% and prevalence of lung scars ≥8% (LPHSC) with an ADG of 725 g and reaching target slaughter weight at 25 weeks of age
  4. dScenario 3: a farrow-to-finish farm with prevalence of pleurisy ≥25% (HP) with and ADG of 671 g and reaching target slaughter weight at 26 weeks of age
