Göttingen minipigs were tested in an object recognition procedure based on spontaneous exploration. Eight pigs were exposed to two similar objects in a sample trial and after a one-hour delay exposed to two objects, one familiar and one novel, in a test trial. The pigs explored the novel object significantly more than the familiar object in the test trial (p<0.05), thereby showing recognition of the familiar object. Furthermore, habituation of exploration of the familiar object between the sample trial and the test trial was found (p<0.05). The procedure can be useful for testing of spontaneous trial-unique memory in pigs.
在基于自发探索的物体识别程序中对哥廷根小型猪进行了测试。八只猪在样本试验中接触两个相似的物体，在延迟一小时后，在测试试验中接触两个物体，一个是熟悉的，一个是新的。在测试试验中，猪对新物体的探索明显多于熟悉的物体（p<0.05），从而表明对熟悉物体的识别。此外，还发现了在样本试验和测试试验之间对熟悉物体探索的习惯化（p<0.05）。该程序可用于测试猪的自发试验独特记忆。
