Abstract:

The common marmoset (Callithrix jacchus), a primate species belonging to the genus Callithrix in the family Callitrichidae, has multiple advantages including small body size, short reproductive cycle, early sexual maturity, 1-3 offspring per litter, and ease of experimental manipulation. It also exhibits behavioral characteristics such as vocal communication and strict monogamy. Common marmosets present unique advantages in neuroscience and brain disease research and are widely used in biomedical fields including neuroscience, gene editing, and ethology. Experimental common marmosets (hereinafter referred to as "experimental marmosets") require management of breeding and use to ensure traceable pedigrees and prevention of inbreeding. Existing management systems developed for rodents or Macaca often cannot effectively meet the practical needs of experimental marmoset management in key aspects such as pedigree tracking and inbreeding warning. To address this issue, the Laboratory Animal Center of the Center for Excellence in Brain Science and Intelligence Technology, Chinese Academy of Sciences (hereinafter referred to as "the Center") designed and developed a second-generation information management system for marmosets in 2021 based on its first-generation information management system, and the second-generation system was launched in 2023. This second-generation system adopts a B/S architecture, is modular, and features front-end and back-end separation. It uses mainstream technical frameworks, including Spring Boot, MySQL, and Redis, and integrates 16 functional modules such as basic information, pedigree tree, breeding and experimental selection database, microchip identification management, and ethical supervision. Compared with the first-generation system, the second-generation system optimizes the pedigree tree and basic information modules. It also adds new functions, including purpose-based database partitioning, animal status tracking, abnormal alerts, automatic microchip identification task generation, inbreeding warning, ethical document upload and review, and record management. Together, these form a systematic and refined management and service system covering the entire breeding and experimental use of experimental marmosets. From 2023 to 2025, the practical application at the center shows that it has significantly improved the management efficiency and service level of the experimental marmoset management unit, and can provide a reference for the development of information management systems in other institutions using marmosets.
