Abstract:This study analyzed the relationship between captive female giant pandas' reproduction characteristics and environmental factors. China Conservation and Research Center for the Giant Panda has 2 bases, Wolong Hetaoping Base and Ya'an Bifengxia Base, which are located at 1 848 m±20 m and 1 080 m±42 m in elevation, respectively. In the past10 years, 13 captive female giant pandas had been raised in both bases (5 years in each base). Comparing their reproductive characteristics in this period, statistics showed that there was a significant difference to the litter size and timing of estrus between 2 bases, but had no difference to peak estrogen and pregnancy. In detail, the average litter size was 1.66±0.27 in Wolong Hetaoping Base, and this was extreme significantly different from that of Ya'an Bifengxia Base (1.28±0.24,P<0.01). Additionally, beginning on every January 1, the captive female giant pandas in Ya'an Bifengxia Base experienced a 75.54 days' rutting period on average, and this was about 15 days earlier than that in Wolong Hetaoping Base (P<0.05). Furthermore, the peak estrogen value of the giant panda in Wolong Hetaoping Base was 136.1 ng/mg Cr and 129.7 ng/mg Cr in Ya'an Bifengxia Base (P=0.47). Besides, the pregnancy period of captive female giant pandas in Wolong Hetaoping Base was 120.3 days on average, and about 115.3 days in Ya'an Bifengxia Base (P=0.38). These findings indicated that environmental factors were important and should be taken into consideration in captive giant panda management. Investigations on the relationship between giant pandas' oestrus and photoperiod illumination and temperature could be carried out in further studies, as well as analysis of the mechanisms driving female giant pandas' oestrus at the molecular level.
