摘要
对一只雕消化系统的形态学作了初步的观察与研究,结果表明:雕舌呈鞋底形,舌根分叉,叉粘膜上具有尖端指向后方的栉状突;食管宽而扁,无明显可见的嗉囊;肌胃无明显的类角质膜;肠道长是体长的2.05倍,小肠较发达,长970.5 mm,占肠道总长的75.7%,具有较发达的双侧盲肠。并与蛇雕、毛脚、黑鸢的消化系统进行了比较。
The morphological construction of digestive system of Bubo bubo Linnaeus has been observed preliminarily by naked eyes and dissecting microscope. The results indicate that the tip of the tongue looks like a shoe, while the root of the tongue is bifurcate, and there are many bomblike papillae pointing towards the hind section on the fork of the mucous membrane. The esophagus is wide and flat, and there is no crop that obviously can be seen. On the inside of muscaular stomach there is no obvious construction that is similar to cutin membrane. The length of intestine is 2.05 times as long as that of the whole body. The small intestine with 970.5 mm in length and 75.7% of the whole length of the intestine is relatively developed. The caecum is not degenerate. Besides, the digestive system of Bubo bubo Linnaeus is compared with that of Spilornis cheela, Buteo lagopus and Milvus rnigrans.
