| 摘 要： | 采用聚丙烯酰胺凝胺电泳法对９２头德令哈地区的柴达木黄牛血清淀粉酶同工酶进行了分析。结果发现：（１）柴达木黄牛的血清淀粉酶有ＡＭＹ１，ＡＭＹ２和ＡＭＹ３三种同工酶；（２）ＡＭＹ１同工酶因存在ＡＭＹ１ＢＢ，ＡＭＹ１ＢＣ和ＡＭＹ１ＣＣ三种基因型而表现出多态性；（３）公健牛组与母牛组ＡＭＹ１基因频率和基因型分布没有显著差异。

| Abstract: | Chaidamu yellow cattle in Delingha region were used to analyse the serum amylase isozymes by polyacrylamide gel electrophoresis.The results were as follows:(1)Isozymes of serum amylase consisted of AMY1,AMY2 and AMY3 isozymes in Chaidamu yellow cattle.(2)AMY1 isozyme had three genotypes including AMY1 BB,AMY1 BC and AMY1 CC,showing the polymorphism.(3)There wasn't a significant difference in the gene frequencies and genotype distribution between bull(bullock)and cow groups on the locus of AMY1. |
