JAPANESE NATIVE LIVESTOCK BREEDS

This paper discusses the conservation of native livestock breeds in Japan. These include native Japanese horses, cattle and goats, and domestic Japanese fowls. To best conserve the genes of these genetic resources it is necessary to keep them in the form of (a) live animals and (b) cryogenic storage of sperms, oocytes, embryos, cells, chromosomes and genes. Even that Japanese native livestock are also important as living'museums', it is further desirable to conserve them as live animals. However, there are many problems with conserving all of these breeds in a live form because of their low economic value in the market. For this reasons, it is necessary to combine this with the raising of animals for other purposes such as sale of products, tourist attractions in national parks, zoos and sightseeing farms, educational tools in agricultural schools and experimental animals.
