Based on weights used by Kanis et al. (2005), the relative EV
value of 37.5 for leg condition was assumed. The authors
considered thisweight to be the decrease in production costs
per slaughter pig from one point increase of sow's leg score.
NV values for piglet mortality and weaning-to-mating
interval (traits that were also present in H1), were chosen to
be equal to the EV values, so that total weights for these traits
in scenario 2 were twice as high as in scenario 1.
- Scenario 3, breeding goal for welfare: all traits from
scenario 2 were included, but with NV on LEGw and with
higher NV on PM and WMI:
