A bio-economic simulation study on the association between key performance indicators and pluck lesions in Irish farrow-to-finish pig farms

Table 2 Annual physical outputs obtained from the Teagasc Pig Production Model [30] for the simulation^a of effects associated with different prevalence of pleurisy and lung scars on slaughter pigs on farm performance and profitability

^aA 728 sow farrow-to-finish farm with weekly farrowing batches was simulated to represent three different scenarios
^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
^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
^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
