What is Contract Vivarium? How the Model Works

A contract vivarium is a professionally managed animal research facility that provides biotech companies with research-ready vivarium lab space and services for preclinical in vivo studies, typically using rodent models.

Rather than building and operating their own vivarium, research teams conduct studies within an AAALAC-accredited facility where infrastructure, animal care, and regulatory oversight are already in place.

This model allows biotech and biopharma teams to perform in vivo pharmacology and efficacy studies while avoiding the cost and complexity of building internal animal research facilities.

The Contract Vivarium Model Explained

A contract vivarium (CV) provides fully equipped animal housing and procedure space supported by professional laboratory animal services and compliance oversight.

Core components typically include:

  • Animal holding and procedure rooms for preclinical rodent studies
  • Integrated animal husbandry and veterinary care

Most contract vivarium facilities operate within AAALAC-accredited programs, which recognize high standards for animal care, biosecurity, and research quality.

The Benefits of the Contract Vivarium Model

Contract vivaria provide infrastructure that allows biotech and biopharma companies of all sizes and therapeutic indications conduct in vivo studies without building their own facility or outsourcing early-stage studies to a CRO.

  • Faster Study Initiation: Because the vivarium environment is already operational, companies can begin preclinical studies quickly without the time required to design, build, and staff an internal facility.
  • Control of Studies and Data: Unlike CRO outsourcing, the contract vivarium model allows scientists to conduct and oversee their own experiments, maintaining direct control of protocols, timelines, and data collection.
  • Capital Efficiency: Vivarium construction and operation require significant investment in facilities, equipment, and specialized personnel. Contract vivariums allow companies to allocate capital toward research rather than infrastructure.
  • Scalable Research Space: Most contract vivaria provide flexible space options, allowing companies to begin with a small footprint and expand as programs grow.

Contract Vivarium vs. CRO

Biotech companies without access to vivarium facilities often outsource studies to Contract Research Organizations (CROs). A contract vivarium offers a different approach.

Instead of outsourcing experiments, scientists perform studies themselves within a professionally managed vivarium environment.

This structure allows teams to:

  • Maintain direct oversight of experiments
  • Adjust protocols quickly as programs evolve
  • Monitor results in real time

For early-stage companies generating proof of concept data, this control can be valuable when preparing programs for investor or partner diligence.

The Contract Vivarium Model at Mispro

Mispro operates a network of AAALAC-accredited contract vivarium facilities in major U.S. biotech hubs. These facilities provide research-ready vivarium lab space with integrated animal care and compliance services, including:

  • Fully-equipped animal holding & procedure rooms
  • Shared, semi-private & private options
  • Animal husbandry and colony management
  • Veterinary oversight
  • IACUC regulatory support
  • Vivarium facility management

Within this environment, research teams conduct their own in vivo studies while Mispro manages the operational and compliance infrastructure required for animal research. This space plus services model allows biotech companies to perform preclinical studies in professionally managed vivarium environments while focusing resources on scientific development.

Mispro is North America’s leading contract vivarium organization, with a network of facilities in all major U.S. biotech hubs. Explore how Mispro can enable your preclinical studies.
