Selection of animals based on estimated IGEg contrast.

Tests and observations by week of age (w).
Table 3.
Number of skin lesions for high and low IGE pigs in barren and enriched housing, for each body region, by week of age (w) with weaning at 4 w of age and the regrouping test (RT) at 9 w.
Figure 1.
Aggressive behaviour from life observations.
Percentage of observation spent on reciprocal fighting and non-reciprocal biting for IGE group (low and high IGE) and housing condition (HC, barren and enriched) over weeks of age outside regrouping situations (4 w and 9 w). Significant differences are indicated by *P<0.05.
Figure 2.
Frequency of aggressive interactions within low and high IGE pens during the 30 min after reunion by type of aggressive behaviour. Aggression at feeder includes fighting, biting and head knocks given within <1 m of the feeder. Significant differences are indicated by *P<0.05.
