摘　　要：对7只斑尾榛鸡(Tetrastes sewerzowi)成体的消化系统进行了解剖、测量。消化管总长(161±21)cm,其中小肠、盲肠分别约占消化管总长的40.2%±3.2%和44.9%±2.4%。嗉囊容量约(42±9)ml。相对于其他体重接近的松鸡科鸟类,斑尾榛鸡的盲肠与小肠之比较大,可能与适应消化高纤维的食物有关。The digestive system of the Chinese Grouse （Tetrastes sewerzowi） was observed for the first time in seven adults from the Lianhuashan Natural Reserve in Gansu,China. The gut length was 161 ± 21 cm,with small intestine and cecum consisting of 40. 2% ± 3. 2% and 44. 9% ± 2. 4% of the total length. The crop volume was 42 ± 9 ml. The ratio of cecum to small intestine was higher than that of other grouse species with the similar weight,such as the Hazel Grouse （ T. bonasia） and the White-tailed Ptarmigan （ Lagopus leucurus）, possibly due to the adaptation to fibrous diet.
