藏绵羊和藏山羊小肠黏膜结构的比较研究

[目的]探讨藏绵羊和藏山羊在高寒低氧环境中小肠黏膜结构的适应特征。[方法]采用组织学和图像分析法,对4只藏绵羊和4只藏山羊小肠不同肠段的黏膜结构的形态特征进行比较。[结果]藏山羊小肠绒毛长度和V/C值均显著高于藏绵羊(P0.05),而藏绵羊小肠黏膜的厚度大于藏山羊,但差异不显著(P0.05),藏绵羊小肠肌层的厚度显著大于藏山羊的(P0.05)。[结论]藏山羊的消化吸收功能强于藏绵羊。

Comparative Study on Small Intestinal Mucosal Structure between Tibetan Sheep and Tibetan Goat

[Objective] The aim was to investigate the characteristics of adaptation of small intestinal mucosal structure in Tibetan sheep and Tibetan goat.[Method] The morphology characteristics of mucosal structure in different parts of small intestine between Tibetan antelope(n=5) and Tibetan sheep(n=5) were measured by histological method and the scion image software analysis techniques method.[Result] The length of small intestine villi and V/C values of Tibetan goat were significantly higher than those of Tibetan sheep(P<0.05),the thickness of intestinal mucosa in Tibetan sheep was greater than that of Tibetan sheep,but there was no significant difference(P>0.05).The muscle thickness in Tibetan sheep was significantly greater than that of Tibetan sheep(P<0.05).[Conclusion] The small intestinal digestion and absorption function of Tibetan goat are stronger than that of Tibetan sheep.
