摘　　要：Giant pandas （Ailuropoda melanoleuca） belong to the bear family （Urisidae） within the order Carnivora and specialize on a diet of bamboo, but still retain a typical carnivoran gastrointestinal tract. Consequently, they have a very low energy digestive efficiency （9.5%-34%） if fed only bamboo in captivity. The property of metabolic physiology of giant pandas is an interesting question. McNab [1] wrote in his new book Extreme Measures that ＂basal metabolic rate （BMR） of the giant panda, a semi-arboreal, bamboo-eating bear, has not been measured, but given its habits, it un- doubtedly has a BMR that is appreciably less than expected from （body） mass. Its basal rate is possibly similar to, or less than, that found in the sloth bear （Melursus ursinus）, which feeds heavily on termites and has a basal rate equal to 80% （of expected）. The sloth bear, and presumably the giant panda, differ in energetics from other bears such as omniv- orous black （Ursus americanus） and brown bears （Ursus arctos）, and strictly carnivorous polar bears＂.Giant pandas(Ailuropoda melanoleuca)belong to the bear family(Urisidae)within the order Carnivora and specialize on a di et of bamboo,but still retain a t ypical carnivoran gastrointestinal tract.Con sequently,they have a very low energy digestive efficiency(9.5%–34%)if fed only bamboo in captivity.The property of metabolic physiology of
