大熊猫每天花上14个小时消耗多达12.5公斤(27.5磅)的竹叶和竹竿,但是只能消化大概17%。它们的粪便大多由未消化的竹子残渣组成。
The researchers had been intrigued by how the animals digest bamboo fibre and extractnutrients from it.
研究人员对大熊猫怎么消化竹子纤维,从中获取营养物质很感兴趣。
The researchers found that despite their diet, the giant pandas, together with nine captive and seven wild individuals investigated previously, showed extremely low gut microbiota diversity and an overall structure that diverged from non-panda plant-eaters but was similar to carnivorous and omnivorous bears.
他们发现尽管它们的饮食如此,这些大熊猫,包括之前被研究的9只圈养大熊猫和7只野生个体,都表现出极低的肠道细菌多样性。而且它们肠道菌整体的结构不同于其他植食性动物,反而和肉食性和杂食性的熊类似。
