Study on Digestive System Morphology of Anas poecilorhyncha
[ 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.
