Recent genetic improvement has developed pigs with maximum potential for protein deposit at higher weights; however, their optimal slaughter weight still needs to be determined. The objective of the study was to evaluate live performance, carcass traits, and economic viability of 417 Agroceres PIC pigs slaughtered with 100, 115, 130, and 145kg live weight. Pigs were reared in pens with 10-11 barrows and gilts each, offered a feed allowance of 2.8kg/pig/day until the following slaughter weights (SW): 99.65±0.82kg, 118.53±0.98kg, 133.97±1.17kg, and 143.90±1.24. There was no interaction between sex and SW (P>0.05). Backfat thickness, fat area, and loin eye area linearly increased with SW (P0.05), and feed conversion ratio (R²=43.29%) linearly worsened with SW (P0,05). A espessura de toucinho, área de gordura e área de olho de lombo aumentaram linearmente com o PA (P0.05) e a conversão alimentar (R²=43,29%) apresentou discreta piora linear com o PA (P |
