At present, most laboratory animal centers in colleges and universities have adopted or developed information management systems for laboratory animals; However, these systems vary significantly in terms of functional modules, the refinement level of management, and logical relationships.Based on an analysis of the current status of laboratory animal management systems in colleges and universities, and combined with the practice of our institution, this paper develops a refined, full-process information management system centered oncage units. By using QR codes to identify cages, the system integrates information such as facility environment, feeding management, veterinary inspection, and breeding management onto each cage. Users with different identities can obtain relevant information on the cages in real time, which significantly improves the efficiency and transparency of laboratory animal management, enhances the level of refined management and quality control, and promotes resource integration and open sharing. This system provides a new approach for the information management of laboratory animals in universities.
