Who Performs Experiments on Live Animals
People who perform experiments on live animals include university researchers, contract research organizations, government agency scientists, and private company laboratories. In the United States, the USDA Animal and Plant Health Inspection Service maintains records of registered research facilities, and the most recent annual reports list thousands of sites where vertebrate animals are used in studies. Companies in the pharmaceutical, biotechnology, and agrochemical sectors employ large teams of veterinarians, scientists, and technicians to design and execute these protocols, often under oversight from institutional animal care and use committees. For an overview of regulatory definitions and reporting requirements, see the USDA APHIS Animal Welfare Act pages here.
In Europe, the European Commission publishes statistics on animals used for scientific purposes, with the latest reports covering millions of vertebrates across member states. Major contract research organizations such as Charles River Laboratories and Covance (a subsidiary of Labcorp) operate global networks of facilities where people who perform experiments on live animals follow standardized protocols for toxicology, safety pharmacology, and disease modeling. These organizations employ individuals with titles such as study director, principal investigator, animal technologist, and veterinary pathologist, each with defined responsibilities under Good Laboratory Practice regulations. The OECD publishes guidance documents that harmonize testing approaches across jurisdictions.
Common Species and Models
Mice, rats, fish, and birds account for the vast majority of animals used in experiments worldwide, with rodents representing over 90 percent of vertebrates in many national statistics. Larger animals such as dogs, rabbits, and non-human primates are used in a smaller share of studies, often for regulatory toxicology and safety assessment required before human clinical trials. Specific genetic models, including transgenic and knockout animals, are bred to study disease mechanisms, and people who perform experiments on live animals in these programs follow strict breeding and welfare protocols.
Regulatory Framework and Oversight
In the United States, the Animal Welfare Act sets minimum standards for the humane treatment of animals in research, and the National Institutes of Health enforces additional policies for grant-funded studies. The Institutional Animal Care and Use Committee reviews protocols, inspects facilities, and ensures that personnel who perform experiments on live animals receive appropriate training. The Office of Laboratory Animal Welfare at NIH provides guidance on the Public Health Service Policy on Humane Care and Use of Laboratory Animals, which applies to all research funded by PHS agencies.
The European Union Directive 2010/63/EU establishes rules for the protection of animals used for scientific purposes, requiring project authorization, severity classification, and replacement, reduction, and refinement principles. In many countries, people who perform experiments on live animals must hold specific licenses or certifications, and facilities undergo periodic inspections by national authorities. The International Council for Laboratory Animal Science publishes global standards that influence national regulations and corporate research policies.
Three Rs and Emerging Alternatives
The three Rs framework, introduced by Russell and Burch, promotes Replacement, Reduction, and Refinement as guiding principles for ethical animal research. Regulatory agencies increasingly accept non-animal methods such as in vitro assays, organ-on-a-chip platforms, and computational models, and funding bodies prioritize projects that implement these alternatives where scientifically valid.
Industry Trends, Funding, and Market Data
The global contract research organization market, which includes many facilities where people who perform experiments on live animals work, has been valued at tens of billions of dollars, with growth driven by drug development pipelines and expanding regulatory requirements in emerging markets. Major pharmaceutical companies allocate significant budgets to preclinical animal studies as part of the drug approval process, and public-private partnerships fund translational research in areas such as oncology, neuroscience, and infectious diseases.
