在人类和大鼠中，已知妊娠期间会发生情感变化，但尚不清楚妊娠如何影响其他非人类哺乳动物的情绪。这项研究评估了猪的判断偏差的变化，作为整个妊娠期间情感状态的衡量标准。训练猪完成空间判断偏差任务，参考积极和消极的位置。我们测试母猪交配前，并在妊娠早期和晚期，通过评估他们的反应模棱两可的探针位置。随着妊娠的进展，猪对模棱两可的探针的反应越来越消极，并且在基线乐观度方面存在一致的个体间差异。这表明猪的情感状态可能在妊娠期间发生了改变，尽管没有对非妊娠对照组进行测试，但不能排除学习的影响。这些结果表明，判断偏差是在妊娠期间改变家猪，从而提高新的福利考虑圈养多产物种。
In humans and rats, changes in affect are known to occur during pregnancy, however it is unknown how gestation may influence mood in other non-human mammals. This study assessed changes in pigs' judgment bias as a measure of affective state throughout gestation. Pigs were trained to complete a spatial judgment bias task with reference to positive and negative locations. We tested gilts before mating, and during early and late gestation, by assessing their responses to ambiguous probe locations. Pigs responded increasingly negatively to ambiguous probes as gestation progressed and there were consistent inter-individual differences in baseline optimism. This suggests that the pigs' affective state may be altered during gestation, although as a non-pregnant control group was not tested, an effect of learning cannot be ruled out. These results suggest that judgment bias is altered during gestation in domestic pigs, consequently raising novel welfare considerations for captive multiparous species.
