摘要: 本文对凉山山系大熊猫对竹子资源选择利用进行了研究，发现对不同的竹类有不同程度的选择性。最喜食大叶筇竹和白背玉山竹，几乎不选择刺竹子；就大叶筇竹而言，喜食基径大于１０ｍｍ的幼竹竹茎，特别喜食基径大于１８ｍｍ的竹笋；就白背玉山竹而言，喜欢选择基径大于１２ｍｍ的竹茎和基径大于１６ｍｍ的竹笋，但对白背玉山竹的老嫩无明显选择。

摘要: 对圈养的１３头大熊猫肠道正常菌群进行了定性及定量检测，发现大熊猫肠道正常菌群与其他动物有较显著差异，厌氧菌的检出率及检出量相对较低，其优势菌为肠杆菌科的大肠埃希氏菌，其次为乳杆菌及粪链球菌。同时，本文还着重探讨了上述结果在大熊猫疾病防治及消化生理上的意义。

摘要: 本文对刚接近性成熟大熊猫的精液在电子显微镜下进行精液品质鉴定，观察结果，除少量完成变态的精子外，多数是处在精子发生的各阶段并发育不正常，精液中伴随着大量巨噬细胞和被吞噬的衰亡精子及其碎片。镜检结果不仅说明这只雄性大熊猫性尚未成熟，其生殖系统可能还伴有生理或病理现象，这样的精液建议不能用于配种。

摘要: 本文用ＰＡＰ法对３只大熊猫胃底、幽门腺区、十二指肠、空肠、回肠、结肠和直肠的五羟色胺、生长抑素、胃素、胆囊收缩素、神经降压素、胃动素、抑胃多肽、胰高血糖素、血管活性肠肽和内啡肽的ＩＲ细胞进行了研究。结果表明，大熊猫胃肠道粘膜上皮中具有前八种ＩＲ细胞。对７年龄个体胃肠各段相对数量的比较和各段内分布情况的现实结果表明，除五羟色胺ＩＲ细胞在空肠分布较多外，大多数种类的ＩＲ细胞集中分布于幽门区和十二指肠；幽门区的ＩＲ细胞主要集中在腺颈部附近。与已有的研究比较，大熊猫胃肠道中五羟色胺、胆囊收缩素、胰高血糖素、生长抑素ＩＲ细胞的分布型较为特殊，可能与其特殊的食性和分类地位有关。

摘要: Being widely distributed in the Qinling Mountains,Bashania fargesii is the primary food source for giant pandas (Ailuropoda melanoleuca) during winter and spring.To understand the relationship between panda food habits and nutrients in the bamboo,we collected samples of leaves,branches and stems across seasons and ages in Foping Nature Reserve,Shaanxi Province,China. Each category of samples was collected at the same site,with three replicates,and weighing 200 to 500 gram. Seven trace elements (Zn,Cu,Fe,Mn,Ca,Mg,K) were analyzed by the atomic absorption spectrophometric method. Crude protein was determined following Macro-Kjelhahl procudure,and crude fat was measured with Soxhlet procedure. The results indicated that contents of Mn,Ca,Mg in the leaves and Cu,Zn,Fe in the branches were respectively higher than those in the other parts on bamboo. Compared with those in the branches and stems,contents of crude protein and crude fat in the leaves were significantly higher. In addition,contents of trace elements and nutrients in the bamboos varied across seasons and ages. Leaves are the most nutritious among different parts of bamboo. Food habits exhibited by giant pandas were closely related to nutrition quality of leaves in the bamboo.
