1Weight sold per pig weaned = (final BW * final number of pigs per pen)/Number of weaned pigs needed to fill one finishing pen.
2Fixed day: the final BW at 94 d after housing in the finishing facilities.
3Fixed age: all treatments achieving 164 d of age.
4Fixed weight: all treatments achieving 135 kg of market BW.
