Animal welfare is a crucial aspect of zoological research, with behavioral assessment serving as a key indicator of well-being. This study aimed to evaluate the effects of photoperiod duration, daylight savings shift from winter to summer time, atmospheric pressure, and the occurrence of parturition on the motor activity of Callimico goeldii under zoo conditions. Animal activity analysis was performed via an automatic image analysis method in a family group of nine individuals over two months. Earlier sunrise was associated with an earlier onset of activity, whereas the lengthening of daylight in the afternoon did not affect the extension of motor activity at the end of the day. A decrease in the motor activity of the group was observed after parturition. The demonstrated upward trend in motor activity following the shift from winter to summer time likely resulted from stress due to changes in the timing of Callimico goeldii handling. The results also showed that daily fluctuations in atmospheric pressure constitute a strong stimulant for Callimico goeldii and may cause changes in the functioning of these primates. In conclusion, it can be stated that the environmental and biological factors considered in this analysis can significantly influence the activity patterns of this species and should be taken into account when assessing their welfare under zoo conditions.
动物福利是动物学研究的一个关键方面，行为评估是动物健康状况的关键指标。本研究旨在评估光周期时长、从冬季到夏季的夏令时转换、大气压力以及分娩的发生对动物园环境下金毛伶猴运动活动的影响。通过自动图像分析方法，对一个由九只个体组成的家庭群体在两个月内的动物活动进行了分析。日出提前与活动开始时间提前相关，而下午日照时间延长并未影响一天结束时运动活动的时长。分娩后观察到群体的运动活动减少。从冬季到夏季转换后运动活动呈现的上升趋势，可能是由于金毛伶猴处理时间变化导致的压力所致。结果还表明，大气压力的每日波动对金毛伶猴是一种强烈刺激，可能导致这些灵长类动物的功能发生变化。总之，可以说本分析中考虑的环境和生物因素会显著影响该物种的活动模式，在评估其在动物园环境下的福利时应予以考虑。
