摘  要：
为了研究不同品种肉牛小肠黏膜绒毛结构的差异性,试验采用石蜡切片和H.E.染色方法对4个不同品种成年肉牛的小肠绒毛结构进行组织学观察,并利用显微图像分析技术和统计学方法进行比较。结果表明:西门塔尔牛的绒毛长度最长,与夏洛莱牛比较差异不显著(P>0.05),与草原红牛和利木赞牛比较均差异极显著(P<0.01);草原红牛的绒毛宽度最大,与夏洛莱牛和西门塔尔牛比较均差异不显著(P>0.05),而与利木赞牛比较差异均极显著(P<0.01);草原红牛的隐窝深度最深,与其他品种牛比较差异均极显著(P<0.01);夏洛莱牛的绒毛长度/隐窝深度(V/C)值最大,与利木赞牛和西门塔尔牛比较均不显著(P>0.05),与草原红牛比较差异极显著(P<0.01)。说明不同品种肉牛性成熟时期小肠黏膜的绒毛结构存在不同程度的差异,预示着不同品种肉牛的消化吸收能力、饲料利用率、生长速度等生产性能存在差异。

摘  要：
To investigate the differences of small intestine villi histology in different varieties of beef cattles,The histological observations of small intestine villi in four varieties of beef calves were used by paraffin sections and H.E.routine staining methods,the images were processed and analysed with the Image-Pro-Plus software and Statistics in Medicine SPASS 16.0.The results showed the villus length of small intestine of Charolais cattle was the longest,and there was no significant difference compared with Simmental cattle(P<0.05),there were highly significant differences compared with Red Steppe and Limousine cattle(P<0.01).The villus width of small intestine of Red Steppe was the widest,there were no significant differences compared with Charolais cattle and Simmental cattle(P>0.05),and there was a highly significant difference compared with Limousine cattle(P<0.01).The crypt depth of small intestine of Red Steppe was the deepest,there were highly significant differences compared with others(P<0.01).The ratio of villous length to crypt depth(V/C) for Charolais cattle was the biggest,there were no significant differences compared with Limousine cattle and Simmental cattle(P>0.05),but there was a highly significant difference compared with Red Steppe(P<0.01).It displayed that there were different degrees of differences in villi structure of small intestine mucosa during the sexual maturation for different varieties of beef cattle,indicating existence of differences on absorption capacity,growth rate,feed efficiency and other performance indicators.
