Research Animals

Welfare of Animals in Biomedical Research Facilities

Millions of animals live in research facilities worldwide, often in conditions that compromise their behavioral and psychological welfare.

Key Facts

Over 100 million animals are used in research globally each year
Social isolation is common despite most species being social
Repeated handling causes chronic stress responses
Many facilities lack environmental enrichment
The 3Rs framework (Replace, Reduce, Refine) is often inadequately applied

Welfare Considerations

Standard laboratory housing frequently denies animals natural behaviors essential to their wellbeing. Mice need nesting material; pigs need rooting substrates; primates need complex social environments. Stress in research animals also compromises the scientific validity of results, making welfare reform a scientific as well as ethical priority.

What You Can Do

Advocate for mandatory enrichment standards in research facility regulations
Support funding for alternative testing methods development
Demand transparency in animal use reporting from research institutions
Encourage institutions to adopt AAALAC accreditation with enhanced welfare standards
