These experiments were carried out to find genetic polymorphisms of Serum protein like Pre-albumin(Pr), Albumin(Al) and Transferrin(Tf), and establish preservation of pure pedigree in Korean Native Goats(KNG). Their serum was collected and examined from the total of 74 KNG that raised in Tang Jin district, Chungnam-province. They were biochemically analysed by polyacrylamide gel(7.5%) electrophoresis(PAGE) in order to estimate the frequencies of genotypes and alleles existing on each trait locus. The results obtained in these experiments were summarized as follows ; 1. In the serum Pre-albumin(Pr) locus, the frequencies of genotypes for hetero AB and homo BB observed were 55.4%, and 44.6%, respectively. While homo AA was not found in the Pr locus. The frequencies of gene in PrA and PrB were 0.723 and 0.277, respectively. Accordingly, the Pr loci were assumed to be controlled by alleles PrA and PrB. 2. The frequencies of genotypes of homo BB and hetero AB detected in Albumin(Al) locus were 75.7% and 24.3%, respectively. However, AA type was not observed in the Al locus. The gene frequencies of AlA an AlB were 0.879 and 0.121, respectively. Also, the Al loci were considered to be controlled by alleles AlA and AlB. 3. The frequencies of genotypes for hetero AD and homo DD found in Transferrin (Al) locus were 79.7% and 20.3%, respectively. Whereas, homotype AA was not detected in this locus. The gene frequencies of TfA and TfD were 0.399 and 0.601, respectively. Therefore, the serum Tf loci were assumed to be controlled by alleles Tfa and Tfd.
