Performance of ALLO-treated and untreated LBW and NBW pigs in the cognitive pig holeboard task.

The transition from the originally learned pattern of baited holes to a new pattern (reversal) was taken as index for response flexibility. Strategies are reflected by the measure choice correspondence and have been analyzed across block of trials without considering through which pigs entered the holeboard arena (block differences), and also per door. n/a: not applicable.Differences between 4 treatment groups: Performance of LBW and NBW piglets born from allopurinol treated sows (n = 6) and controls (n = 4).
