Table 1.
Descriptive statistics (mean ± SD), reliability of Evaluated Breeding Value (EBV) for measured traits in Duroc boars.
Figure 1.
Manhattan plot showing association with feeding behavior traits for all the SNPs.
The horizontal line indicates genome-wide significant threshold. On vertical, Manhattan plot for total daily feed intake (DFI), total time spent at feeder per day (TPD), number of visits to the feeder per day (NVD), time spent to eat per visit (TPV), mean feed intake per visit (FPV), and mean feed intake rate (FR), respectively. Chromosome 19 stands for X chromosome. Chromosome 0 stands for unmapped SNPs.
Figure 2.
Linkage disequilibrium (LD) pattern and Ensemble genes on region from 62–65 Mb on pig chromosome 1.
LD blocks are marked with triangles. Values in boxes are LD (r2) between SNP pairs and the boxes are colored according to the standard Haploview color scheme: LOD >2 and D' = 1, red; LOD >2 and D'<1, shades of pink/red; LOD<2 and D' = 1, blue; LOD<2 and D'<1, white (LOD is the log of the likelihood odds ratio, a measure of confidence in the value of D').
Figure 3.
Linkage disequilibrium (LD) pattern and Ensemble genes on region from 33.5–35.5 Mb on pig chromosome 12.
LD blocks are marked with triangles. Values in boxes are LD (r2) between SNP pairs and the boxes are colored according to the standard Haploview color scheme: LOD >2 and D' = 1, red; LOD >2 and D'<1, shades of pink/red; LOD<2 and D' = 1, blue; LOD<2 and D'<1, white (LOD is the log of the likelihood odds ratio, a measure of confidence in the value of D').
