| 摘要: |
| 采用系统随机整群抽样法在平利黄牛分布区选择三个系统八个群体抽取样本125头,以血液蛋白质多态性、毛色分布和外形特征作为遗传标记检测该黄牛的品种资源。结果表明,平利黄牛所持有的基因库基本反映了我国黄牛品种的特点,含有部分瘤牛血统,属于我国黄牛从北方向南方分布的一个过渡型地方黄牛品种。 |

| Abstract: |
| The genetic monitoring was carried out on eight herds(n = 125) from three systems of Pingli Yellow Cattle with blood protein polymorphism loci, coat color loci and exterior features as genetic markers by the stratified random cluster sampling in the central area of the breed distribution. The results showed that Pingli Yellow Cat'tle has some distinctive features of other Chinese Yellow Cattle breeds affected by Bos Indicus (Zcbu)during their origin and evolution. Pingli breed is a transitional 1'pcal Chinese Yellow cattle breed distributed from the North to the South in China. |
