Table 2. Estimates of genetic, litter, and residual variance for birth weight (kg) (BW), its environmental variance (BWv), and survival rate (SU) in pigs (standard error in parentheses).
| Variance component | BW (×10−3) | BWv (×10−3) | SU (×10−3) |
|---|---|---|---|
| Genetic variance | 16.4 (1.51) | 46.5 (7.55) | 0.968 (0.22) |
| Litter variance | 15.0 (0.80) | 75.0 (7.53) | 2.74 (0.26) |
| Residual variancea | 74.9 (0.61) | 1803 (14.7) | 63.4 (0.50) |
