The construction of laboratory animal facilities which involves many specialties is a complex project.For improving the research work there,as well as the reliability of safety test on foods,cosmetics,and other health products in the limited clean animal laboratories,Chinese Academy of Preventive Medicine (CAPM) has built a clean animal facility for more research and inspection projects,through selecting the construction team openly and publicly,consulting with laboratory animal experts,and supervising the constructive quality.And in CAPM an Experimental Animal Laboratory was established which is available for several institutes,achieving its aims for conforming to the National Standard,satisfying the needs,saving energy,reducing manpower,using the facility efficiently and decreasing the maintenance expenses.The management is also changed from the lower standard and dispersion to the higher standard and centralization.CAPM has been getting big benefit from the change of managemental model.
