摘要
以藏鸡和来航鸡为研究对象,探究高原和平原环境中小肠黏膜结构的形态特征差异。采用计量组织学和图像分析法,对3只藏鸡和3只来航鸡不同肠段黏膜结构的形态特征进行比较。结果表明,来航鸡小肠绒毛的高度都高于藏鸡,空肠和回肠间差异极显著(P<0.01),十二指肠间差异不明显;来航鸡小肠绒毛的宽度都极显著大于藏鸡(P<0.01);来航鸡十二指肠的肠绒毛隐窝深度极显著大于藏鸡(P<0.01),空肠和回肠间的差异不明显;来航鸡小肠绒毛肌层厚度都极显著大于藏鸡(P<0.01);来航鸡的消化吸收功能强于藏鸡。
The aim was to investigate different features of small intestinal mucosal structure in Tibetan chicken and Leghorn from high- low land.The morphological character of mucosal structure of each intestinal segments were measured by histology and metrology.The length of jejunum and ileum of Leghorn were significantly higher than those of Tibetan chicken(P<0.01),but not significant to duodenum. The width of the small intestine villi of Leghorn were significantly higher(P<0.01). The enteraden depth of the duodenum of Leghorn were significantly higher(P<0.01), but not significant to jejunum and ileum. The thickness of muscular layer of Leghorn were significantly higher(P<0.01).The digestion and absorption of the small intestinal of Leghorn were stronger than Tibetan chicken.
