竹笋是大熊猫(Ailuropoda melanoleuca)最为喜爱的天然食物。竹笋相对于竹叶和竹茎含水量更丰富,粗纤维含量更低,适口性更好;大宗养分、微量元素、必需氨基酸等含量丰富(周昂等,1996;唐平等,1997;周材权等,1997),而丹宁等具有微毒性的次生代谢物含量却最少(赵晓红等,2001),更利于大熊猫对生活必需营养的吸收 Bamboo shoots are the favorite natural food for the giant panda (Ailuropoda melanoleuca). Compared with bamboo leaves and bamboo stems, bamboo shoots have more water content, lower crude fiber content and better palatability; abundant nutrients, trace elements and essential amino acids (Zhou Ang et al., 1996; Tang et al., 1997; Et al., 1997). However, the content of secondary metabolites such as tannin with minimal toxicity (Zhao et al., 2001) is more favorable to the panda’s absorption of essential nutrients
