摘要
为研究不同品种肉牛小肠组织形态的差异性,取成年肉用草原红牛、利木赞牛和夏洛莱牛的小肠空肠段,制作石蜡切片,常规HE染色,利用显微图像分析技术进行比较研究。结果表明:小肠绒毛长度草原红牛与利木赞牛比较差异极显著(P<0.01),草原红牛与夏洛莱牛比较差异不显著(P>0.05),利木赞牛与夏洛莱牛比较差异极显著(P<0.01);隐窝深度和黏膜厚度3个品种间差异极显著(P<0.01);绒毛长度/隐窝深度(V/C)值草原红牛与利木赞牛及夏洛莱牛比较均差异极显著(P<0.01),利木赞牛与夏洛莱牛比较差异不显著(P>0.05);肌层厚度草原红牛与利木赞牛差异极显著(P<0.01),草原红牛与夏洛莱牛差异不显著(P>0.05),利木赞牛与夏洛莱牛差异极显著(P<0.01)。研究显示:不同品种肉牛小肠组织结构存在明显差异,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。
To investigate the differences of small intestine histology in different varieties of beef cattle,samples of small intestine jejunum in adult Grassland Red,Limousine and Charolais beef cattle were taken out and embedded in paraffin sections.Sections were stained by HE conventional methods and the images were processed and analysed with the Image-Pro-Plus software and Statistics in Medicine SPASS16.0.The results showed the difference of the Villus length of small intestine between Red Steppe and Limousine cattle was significant（P0.01）,between Red Steppe and Charolais cattle was not significant（P0.05）,between Limousine cattle and Charolais cattle was significant（P0.01）;The difference of the Crypt depth and the Mucous depth of small intestine among the 3 varieties was significant（P0.01）;The difference of V/C value between Red Steppe and Limousine cattle was significant（P0.01）,between Red Steppe and Charolais cattle was significant（P0.01）,between Limousine cattle and Charolais cattle was not significant（P0.05）;The difference of Submucous muscle layer depth between Red Steppe and Limousine cattle was significant（P0.01）,between Red Steppe and Charolais cattle was not significant（P0.05）,between Limousine cattle and Charolais cattle was significant（P0.01）;It indicated that there were significant differences of small intestine histological among different varieties of beef cattle which have an effect on Growth rate and Feed efficiency of performance indicator.
