9.Summary of Research Results

 The world population is more than 5.6 billion at the present time and is expected to exceed 10 billion by the middle of the 21st century. Foods of animal origin contain a plenty of nutrients and suit people’s taste. The demand for food animal protein resources is, therefore, increasing year-by-year and animal scientists are compelled to find a solution to suffice the expanding needs and improve the quality of human life. In order to meet such an increase in demand of farm animal products such as meat and milk in the world, technological innovation based on the progress in animal sciences must be promoted. The aim of our project is to investigate the basic and practical subjects on animal reproduction as follows in order to increase efficiently livestock by the improvement of development bioengineering techniques, and the fruition of our project as follows: (1)the production of cloned animals from somatic cells in cattle, a farm animal, (2)in vitro maturation of oocytes, fertilization and embryo culture in the farm animals (cow and sow), (3)cryopreservation of gametes and embryos of livestock and of ovaries, and (4)other basic and practical subjects concerning animal reproduction and its relating physiology (ex. Molecular regulating mechanism of ovarian follicule selection, a critical ovarian phenomenon).
