Managing Multi-Site Vivarium Operations
Organizations with multiple vivarium sites face unique challenges in census management:
Capacity balancing: Sites have different cage capacities and utilization rates. Transfers can relieve an overcrowded site but may push the receiving site over capacity if not planned carefully — especially when quarantine cages are factored in.
Quarantine impact: Incoming transfers require quarantine space that temporarily increases cage load. A 10-cage transfer with 14-day quarantine effectively occupies 10 additional cages for two weeks. The planner accounts for this overlap.
SPF status maintenance: Transfers between sites with different specific-pathogen-free (SPF) statuses require careful biosecurity planning. Animals moving from a lower to higher SPF barrier need extended quarantine and health testing.
Study scheduling: Multi-site studies often involve breeding at one site, in-life work at another, and necropsy at a third. Coordinating animal flow across these sites requires tracking census at each location week by week.
Regulatory considerations: International transfers add customs clearance, health certificates, and import permits. These can add 2–6 weeks to transfer timelines and should be factored into planning.
