Back fat average (mm)
Figure 10.8. Individual sows plotted according to average backfat and duration of farrowing. The horizontal
dashed line distinguishes prolonged farrowings (>300 min; areas A, B). The vertical dotted line distinguishes
the fatter sows (areas B, D). The solid regression line represents a positive relationship between average
backfat and duration of farrowing (Oliviero et al ., 2010).

Constipation score (mean)
Figure 10.9. Individual sows plotted according to average constipation index score (CI) and duration of
farrowing. Low CI values indicate constipated sows, whereas high CI values indicate unconstipated sows.
The horizontal dashed line distinguishes prolonged farrowings (>300 min; areas A, B); the vertical dotted
line distinguishes constipated sows (areas A, C). The solid regression line represents a negative relationship
between the constipation index and the duration of farrowing (Oliviero et al ., 2010).
