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 dehydroge2 nase (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 calcu2 lated 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 practi2 cable on population phylogenesis studies
