Abstract: Objective To understand the differences on serum monoamine neurotransmitters (5-hydroxytryptamine, norepinephrine, dopamine) in single caged and social group female macaca fascicularis and ECG, blood pressure which were associated with the emotion, explored the influence of living environment on the emotion of macaca fascicularis. Methods Nine female macaca fascicularis 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 macaca fascicularis 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.
