| 摘 要： | 采用聚丙烯酰胺凝胶电泳法对德令哈地区56头柴达木黄牛和17头杂种黄牛的α-乳白蛋白(α-LA)和β-乳球蛋白(β-LG)进行分析。结果发现：(1)该地区柴达木黄牛的α-LA和β-LG位点均具有多态性，但α-LA位点的基因杂合度很低(0.0089)。(2)杂种牛的α-LA位点，只有α-LABB一种基因型而呈单态，β-LG位点有三种基因型而呈多态性，且基因杂合度较高(0.500)。 |

Analysis of α-Lactalbumin and β-Lactoglobulin for Chaidamu Yellow Cattle and Its Crossbred Cattle by Electrophoresis |
|
| Abstract: | 56 Chaidamu yellow cattle and 17 crossbred cattle were used toanalyse α-lactalbumin(α-LA) and β-lactoglobulin(β-LG) by means of polyacrylamide gel electrophoresis.The results were as follows:(1)There was a polymorphism on the loci of α-LA and β-LG for Chaidamu yellow cattle in the region.The gene heterozygosity on the locus of α-LA was very low(0.0089).(2)There was single α-LA BB phenotype on the locus of α-LA for crossbred cattle ,showing monomorphism.There were three phenotypes,showing polymorphism and the gene heterozygosity on the locus of β-LG was higher (0.5000). |
