摘要
目的了解单笼与群居饲养雌性食蟹猴的血清单胺类神经递质[去甲肾上腺素(NA)、5羟色胺(5-HT)、多巴胺(DA)]及与情绪相关的心电、血压的差异,探讨生活环境对食蟹猴情绪的影响。方法选取9只4~6岁雌性食蟹猴,前5个月单笼饲养,后5个月群居饲养,分别测量其心电、血压、NA、5-HT、DA、日常表情行为等相关指标。结果整个实验期间,心电参数中的心室率、PR间期、QT间期及血清单胺类神经递质(NA、5-HT、DA)、血压中的舒张压值等指标组间比较差异显著(P<0.05或P<0.01)。单笼阶段的愤怒、焦虑因子得分显著高于群居;性行为、活动度、快乐因子得分显著低于群居(P<0.05)。结论食蟹猴更适合群居饲养,如果长期单笼饲养,将对其血清单胺类神经递质及心电、血压参数中某些指标产生较大影响,并易于产生多种负面情绪。
Objective To understand the differences on serum monoamine neurotransmitters （5- hydroxytryptamine, norepinephrine, dopamine） in single caged and social group female macacafascicularis and ECG, blood pressure which were associated with the emotion, explored the influence of living environment on the emotion of macacafascicularis. Methods Nine female macacafascicularis at the age of 4-6 years old were singly raised in cage at the first 5 months, and group raised in next 5 months. The ECG, blood pressure, norepinephrine （NA）, dopamine （DA）, 5-hydroxytryptamine （5-HT） were measured,daily facial expressions also were recorded. Results During the whole experiment, the indexes of ventricular rate, PR interval, QT interval, serum monoamine neurotransmitter （NA, 5-HT and DA） and diastolic pressure; value were compared between groups difference significant （P〈0.05 or P〈0.01）. Anger and anxiety score in single caged stage were significantly higher than in group phase （P〈0.05）, but sexual behavior, activity and happiness score were lower （P〈0.05）. Conclusion The macacafascicularis was more suitable for the breeding of group,during long-term single caged feeding, it could have a greater impact on the serum monoamine neurotransmitters and some indicators of ECG, blood pressure,and were prone to a variety of negative emotions.
