Abstract: [Objective] The purpose of this study was to reveal the preference for edible bamboos of giant pandas and the nutrients comparative of the staple food bamboos.[Method] We observed and recorded the foraging behaviour of 3tested pandas for 1year and collected the 2years breeding data at Chengdu Research Base of Giant Panda Breeding to investigate the preference of giant pandas for edible bamboos.At the same time,the nutrient components,including crude protein, crude fat,crude fiber,crude ash,energy,calcium and phosphorus of staple food of bamboos were analysed and made comparison between each other.[Results] The captive giant pandas like all kinds of bamboo shoots,the leaf of Bambusa fargessi,the stem of Phyllostachys nidularia and Pleidolastus amarus.Among the staple food of bamboo,the mean content of crude protein and crude fat in Qiongzhuea opienensis shoot are significantly higher than those of Phyllostachys nidularia shoot and Chimonobambusa quadrangularis shoot,but its crude fiber content is the lowest.For bamboo,the nutrient components of crude protein and crude ash followed a pattern:leaf > branch > stem,but the crude fiber content presented another pattern:stem > branch > leaf.[Conclusion] The captive giant pandas prefer to bamboos with higher content of crude protein, higher energy to protein ratio,lower content of crude fiber,the palatability also affected their foraging behaviours.
