Blood types in pigs are divided into two types, A and O type. It is important to select and breed O-type pigs that have no hematologic rejection, because the blood type of the donor is an important factor causing immune rejection in xenotransplantation. Therefore, the gene that determines the blood type is GGTA1(glycoprotein, alpha-1,3-galactosyltransferase 1), which generally belongs to the ABO blood group. This study was carried out to develop a simple and accurate method by analyzing the structure of GGTA1 gene which determines blood type. A primer was designed to allow easy identification of the blood type of the target in the first and second deletion regions of intron 7 to distinguish between the A and O genotypes. That is, for the purpose of identifying the blood type using length difference after the PCR, the forward and reverse primers were designed in the highly conservative region. As a result, a pair of primers were prepared and PCR amplification was performed to distinguish three types of genotypes, AA, AO, and OO, using the length difference by electrophoresis. Using the above primers, the parents and their offspring were compared with each other to confirm the correct genetic pattern. And, in four pig breeds, the genes were amplified and the genotype could be correctly identified. In this study, we could diagnose the blood type of AA, AO, OO genotype of pigs by using primer of INDEL region. Especially, since it is possible to diagnose the genotype by the length difference, it is possible to diagnose it quickly and accurately from the gene amplification to the genotype reading
