Construction of animal genome database and gene analysis for animal improvement

 We are developing genomic resources of livestock animals and providing information to contribute in the development of high-quality, safe and secure livestock products. We have decoded more than 10,000 expressed genes (full length cDNAs) and cooperated in the International Swine Genome Sequencing Consortium. We also developed the methods for discrimination of breeds or individuals by using DNA polymorphism, and identified the genes responsible for the number of vertebrae and meat color in pigs. Now, we are increasing the accumulation of the genomic information in livestock animals such as pigs. We are also developing methods for detecting the association between gene polymorphisms and phenotype. With the effective utilization of genomic information, we are aiming to identify the genes responsible for meat quality, growth rate, disease resistance, reproductive performance, and other traits. We can use genomic information to develop gene markers that support rapid breed improvement for meat quality, productivity, and disease resistance. Management of production with the gene markers enables us to supply the variety of products corresponding to various needs of consumers.
