| 摘 要： | 采用水平板淀粉凝胶电泳法检测了52头迪庆藏猪的13个血液蛋白座位的多态性，并计算各座位等位基因的频率及其估计误差以及基因频率估计值的精确度和可靠性。结果发现，迪庆藏猪在Tf、Cp、Am、Hp、6PGD、CEs、Ca共7个座位表现出多态性，并分别受控于3、2、5、5、2、2、3个常染色体等位基因。其余6个座位(Pa 、EsD、 PHI、 PGM、 G6PD、 MDH)未检测出多态性。 |

| Abstract: | In the present study, analysis of 13 blood protein loci obtained from 52 Diqing_Tibetan pigs was carried out by means of horizontal starch gel electrophoresis. Polymorphism was found in seven loci, i.e. the Transferrin (Tf), Ceruloplasmin (Cp), Amylase(Am), Hemopexin(Hp), 6_Phosphogluconate dehydrogenase(6PGD), Cell esterase(CEs) and Carbonic anhydrase(Ca), which consisted of 3, 2, 5, 5, 2, 2 and 3 alleles, respectively. A new variant was discovered at Ca locus. The allele frequencies at each locus were calculated and their precision degree and confidence were also estimated simultaneously. The other six loci, namely Prealbumin(Pa), Esterase_D(EsD), Phosphohexose isomerase(PHI), Glucose_6_phosphate dehydrogenase(G6PD), Phosphoglucomutase(PGM) and Malate dehydrogenase(MDH), were monomorphic. This paper revealed the rich blood protein polymorphisms in Diqing_Tibetan pig and indicated that the method was practicable on population phylogenesis studies. |
