- Traits at the piglet level: HEAD CLASS = head morphology (normal or IUGR) and Ind BWT = individual birth weight
- Traits at the sow level: PROP IUGR = proportion of piglets with an IUGR head morphology within a litter, AVE BWT = average birth weight within a litter, SD BWT = within-litter standard deviation in birth weight, litter size, PROP SURV = proportion of a litter surviving to processing, and GL = gestation length
- SD standard deviation
