松鸦消化系统形态的初步研究

对松鸦消化系统的形态学作了初步的观察与研究,为松鸦的保护利用、饲养及生物学研究提供形态学的基础资料,结果表明:松鸦舌呈宽阔三角形,舌尖分叉呈"V"字型,分叉深为0.96 mm,黏膜上具有尖端指向后方的栉状突;食道颈胸分段不明显,食管全长55.34 mm,食管与嗉囊分界明显,嗉囊显著膨大;腺胃上具有数目较多且均匀分布的圆形乳突,肌胃发达;肠全长454 mm,约为体长的2.06倍,小肠较发达,长419 mm,占肠道总长92%;左右侧盲肠长5.46 mm,占肠道总长1.2%;直肠占肠道总长2.6%;肝分左右两叶;胰细长形,分两小叶。这些消化道特征说明松鸦是以食虫为主的杂食性鸟类。
