Table 3.
Depth and completeness of the pedigree for all, phenotyped, and genotyped animals
| Animals | Parameter1 | Mean | Min2 | Max |
|---|---|---|---|---|
| All | Maximum generations traced back | 31.05 | 0.00 | 48.00 |
| Equivalent complete generations (ECG) | 17.15 | 0.00 | 28.64 | |
| Pedigree completeness index (PCI) | 0.92 | 0.00 | 1.00 | |
| Phenotyped | Maximum generations traced back | 41.72 | 35.00 | 48.00 |
| ECG | 24.25 | 17.27 | 28.64 | |
| PCI | 0.99 | 0.77 | 1.00 | |
| Genotyped | Maximum generations traced back | 44.69 | 22.00 | 48.00 |
| ECG | 25.36 | 10.92 | 28.64 | |
| PCI | 0.98 | 0.00 | 1.00 |
1Maximum generations traced back = number of generations between animal and its earliest ancestor; ECG = the number of generations in a comparable complete pedigree; PCI = percentage of known ancestors.
2A zero estimate of the minimum depth and completeness of the pedigree is due to the presence of founder animals. When phenotyped or genotyped animals were considered, a zero or very small estimate PCI was only observed in two animals that had no relationships reported either due to errors or under reporting.
