Institute of Animal Science, Chinese Academy of Agricultural Sciences was established in 1957 and it is a national multi-discipline research organization in the field of animal sciences. The Institute of Animal Science, Chinese Academy of Agricultural Sciences sets up 5 research departments, namely: Animal Nutrition and Feed Science, Animal Biotechnology and Reproduction, Animal Germplasm Resources and Production, Grassland Science and Veterinary Medicine as well as a central laboratory for chemical analysis. Institute of Animal Science, Chinese Academy of Agricultural Sciences carries out applied and fundamental research and technical development and research with swine, poultry, cattle, sheep and goats as main research objectives. The institute puts emphasis on the areas of germplasm resources, genetics and breeding, reproduction, feed science, nutrition and animal bio-technology, veterinary medicine, in order to solve the scientific and technical problems in animal production which are crucial, basic, commonly encountered or orientation-determining for the animal production. Moreover it is also engaged in organizing and coordinating key national research projects, extension of research achievements and advanced techniques, training of high-ranking scientists and technicians, promotion of domestic and international scientific exchange and collaboration.
The National Natural Science Foundation of China(NSFC) plays an important role in promoting the ability of undertaking national scientific and technical projects, enhancing the basic research and independent innovation, supporting the industrial development, training research teams and extending the international academic influence for the Institute of Animal Sciences of the Chinese Academy of Agricultural Sciences.
Based on the summary and analysis of the number of applications and projects funded by NSFC, the funded rate and the distribution of disciplines and fields since the implementation of the 12th Five-Year Plan from the Institute of Animal Science, Chinese Academy of Agricultural Sciences, we analyzed the overall development trend and the major driving factors of the growth on projects supported by NSFC from Institute of Animal Science, Chinese Academy of Agricultural Sciences in three aspects. They are the macro level of the State, the medium level of the institute and the micro-level of NSFC′s delicacy management. Besides, we summarize the refined managerial experience of the institute′s projects funded by NSFC, propagate the culture of NSFC and build up the mechanism of mobilization and examination. Furthermore, based on the gap of the National Natural Science Foundation of China undertaken in our institute, we put forward some ideas about designing the strategic layout in top-level, constructing and developing the discipline and training the talent team. Meanwhile, we also take some measures to tap potential in the application of NSFC, widen application type and increase application quality. At last, we expect to further improve the management and service level of NSFC and move forward the work of NSFC into a new phase, which will provide strong scientific and intellectual support for establishing world-class agricultural research institution and innovation-oriented country. 相似文献
