The purpose of this preliminary study was to lay the foundation for understa nding the phenomenon of mucous production, and to investigate measures whi ch may be related the frequency of mucous excretion. Indicators included the pe riod of abdominal discomfort associated with mucous excretion (mean=2.5±2 .3 h ); the interval from first refusal to consume bamboo and concentrated feed unti l mu cous excretion episode(mean=1.8±2.2 h); the interval fro m first refusal until return of appetite (mean=1.9±2.3 h); the interval from mucous excretion until intake of concentrated feed and bambo o (means=29.8±94.7 min and 33.8±105.8 min, respect ively); the interval between mucous excretion episodes (mean=18.9±24.0 days); mucous characteristics and weight of mucous averaged 1.7±0.7 and 77.8±47.7 g , respectively. Results indicated that the phe nomenon of mucus excretion in the giant panda causes significant disrupti on to daily activity patterns. Animals that excreted muco us more frequently (15 days or less, between bouts) showed significantly more le thargy (P<0.01 and P<0.05), abdominal discomfort (P<0.05), length of time of refusal to eat bamboo (P<0.055 ), and higher mucous weight, than animals that excreted mucous less frequently. Higher frequency of mucous excretion was directly associated with inhibited gro wth, reproduction and health status in the giant pandas studied.展开更多
