摘　　要：为研究重复电刺激对仔猪情绪反应的影响,从6窝仔猪中选取24头配对成12个测试单元,分为处理组和对照组。在处理组中,处理猪共接受2次电刺激(2个刺激阶段间隔10 min),观察猪观察处理猪受刺激过程;在对照组中,两头仔猪均未接受刺激。结果表明:与对照组相比,处理猪的僵直极显著增加,探索均极显著减少(P<0.01);观察猪的尝试逃跑、僵直均显著增加(P<0.05)。与初次刺激相比,2次刺激下处理猪的尝试逃跑极显著减少(P<0.01);观察猪的僵直极显著增加(P<0.01)。具有相似经历的仔猪不会对相同的电刺激表现出更强烈的情绪反应;仔猪会对同伴产生情绪影响,且有观察经历的仔猪看到同伴再次遭受相同刺激时,其情绪反应更强烈。To investigate the repeated electrical stimuli on piglets'emotions,a total of 24 piglets from six litters were selected and paired into 12 test units,divided into the treatment and control groups.In the treatment group,the treated piglets received a total of electrical stimuli twice(twice stimuli phases separated by ten minutes),and the observed piglets witnessed the entire process of the treated piglet being stimulated;in the control group,neither piglet received stimulus.The results revealed a highly significant increase in freezing and a highly significant decrease in exploration in the treated piglets compared to the control group(P<0.01);and a significant increase in escape attempts and freezing in the observed piglets(P<0.05).Compared to the initial stimulus,there was a significant decrease in escape attempts(P<0.01)in treated piglets and a significant increase in freezing(P<0.01)in observed piglets in the second stimulus.These findings suggested that piglets with similar experiences did not display a stronger emotional responses to the same electrical stimulus;piglets displayed emotional responses to their companions,and piglets with observed experiences had stronger emotional responses when they witnessed their companions subjected to the same stimuli again.
