The Institute of Livestock and Grassland Science, NARO (NILGS) is the Japanese research institution for livestock and grassland. We promote the technical developments that integrate studies on grassland, animal feed production, livestock production and animal waste treatment and reuse. NILGS's mission is to contribute to increasing the production of safe and high-quality animal products and improving the self-sufficiency rate of feed by utilizing land resources effectively. Throughout our research, we develop technologies that benefit both present and future livestock production, support our plentiful diet, and finally, contribute to the conservation and sustainable use of national land through development of the livestock industry.
