摘要
对2008年3～11月在四川宝兴县蜂桶寨国家级自然保护区捕获的105只中国鼩猬Neoteracus sinensis进行了解剖，测量和分析了其头骨、体长、部分脏器和胃容物，以提供解剖和测量的生物学数据。结果显示：性比（♀／♂）为1．84，平均胎崽数为5．43只±1．51只；雌雄间头骨量度无显著差异，雄性尾长和后足长明显长于雌性；雄性肝脏重量显著轻于雌性；胃食糜中发现有部分浆果和淀粉类食物，未发现植物的茎叶，主要为肉食性食物。
105 individuals of Neoteracus sinensis were captured from Fengtongzhai National Nature Reserve, Baoxing county, Sichuan province, from March to November of 2008. The skulls, body lengths, liver weights and gastric contents of this spe- cies were measured and analyzed. The results showed： 1 ） the sex ratio （ ♀/♂ ） was 1.84 and every litter size was 5.43 ±1.51 ; 2） the differences in skull measurements between males and females were not significant. The tail lengths and lengths of the hind feet in males were significantly longer than that in females. The liver weights of males were lighter than that of females ; 3 ） No stems or leaves of plants were found in the stomach ; only animal tissue and some berries and starch were found.
