| 摘 要： | 目的]了解斑嘴鸭消化系统与食性关系。方法]对6只成体斑嘴鸭（Anas poecilorhyncha）消化系统进行解剖,并对各器官进行测量。结果]斑嘴鸭消化管总长为（1 889.30±102.11）cm,是体长的（3.700±0.197）倍,其中小肠占消化管总长的73.4%±1.5%,是体长的（2.723±0.196）倍。斑嘴鸭喙扁平,肌肉肥厚,肌胃较发达,小肠最发达,具双侧盲肠但并不发达,仅占消化管的13.0%±0.8%。结论]该研究结果为斑嘴鸭的保护和形态学研究提供了参考。

| Abstract: | Objective] The aim was to understand the relationship with digestive system and feeding habits of Anas poecilorhyncha.Method] The digestive systems of six adult Anas poecilorhyncha were dissected,then were measured.Result] The total length of digestive tube was(1 889.3±102.11) cm,which was(3.70±0.197) times of the body length,and the length of small intestine made up 73.4%±1.5% of digestive tube,which was(2.723±0.196) times of the body length,Anas poecilorhyncha had a flat beak,a flat tongue,thickening muscle,more developed muscular stomach,most developed small intestine and undeveloped bilateral caecum,which account for 13%+0.8% of digestive tube.Conclusion] The results provide some reference for protection and morphological study on Anas poecilorhyncha. |
