Proportion of genetic variance for residual feed intake explained by each LD block. Observed in S (a), and LW (d) for purebred performance (PB) and when alleles originate from S (b), LR (c), or LW(e) for crossbred performance (CB). Top 10 LD blocks explaining most variance for PB (red ▲), and top 10 LD blocks explaining most variance for CB performance (blue ▼). LD blocks belonging to the top 10 in both, PB and CB performance (purple ♦). Regions explaining the variance for PB in more than one breed or explaining the variance for CB in more than one breed-of-origin (light blue strip). *Because of the limited number of RFI records from LR pigs, genetic parameters estimated for LR breed – PB performance had high SE, therefore, estimates are not shown
