title: Working and reference memory of pigs in the spatial holeboard discrimination task.
abstract: The present study investigated whether pigs are able to acquire a complex spatial holeboard discrimination task (4 of 16 holes baited) and whether mixing stress affects performance in this task. All pigs rapidly reduced the number of re-visits to baited holes (working memory) and to unbaited holes (reference memory). Mixing stress did not affect performance.
