Measurements included backfat thickness in vivo and at slaughter in the hot and cold carcass and the weight of carcass, organs and primal cuts. To maximize variations in adiposity a total of 30 females and barrows from two genotypes (Piétrain × (Landrace × Large White) and Large White) were slaughtered at body weights typically used in Europe (i.e. 90 to 150kg) and ground for chemical analysis. Backfat mass (in combination with EBW) was the best indicator for L (L (kg) = 0.0590 × EBW (kg) + 2.99 × backfat mass (kg), R2 = 0.96).
