Research animals are cared for by veterinarians, husbandry specialists, and animal health technicians to ensure their well-being and more accurate findings.
According to Nature Genetics "stressed or crowded animals produce unreliable research results, and many phenotypes are only accessible in contented animals in enriched environments, it is in the best interests of the researchers not to cut corners or to neglect welfare issues." At Cedars-Sinai Medical Center's animal research facility, for example, dogs are given exercise breaks twice daily to socialize with their caretakers and other dogs, and a "toy rotation program" provides opportunities for play.
Basically, animal experimentation has played a dominant role in leading with new findings and human advantages.
Animal research has had a main function in many scientific and medical advances in the past decade and is helping in the understanding of several diseases.
As well as stipulating minimum housing standards for research animals (enclosure size, temperature, access to clean food and water, and others), the AWA also requires regular inspections by veterinarians.
All proposals to use animals for research must be approved by an Institutional Animal Care and Use Committee (IACUC) set up by each research facility.
Through many years, companies have tested animals to help prove that their products are safe for humans.
This has become a very inhumane practice in which many animals are subjected to intolerable cruelty.
Humane treatment is enforced by each facility's IACUC, and most major research institutions' programs are voluntarily reviewed for humane practices by the Association for Assessment and Accreditation of Laboratory Animal Care International (AAALAC).
Laboratory mice, for example, live for only two to three years, so researchers can study the effects of treatments or genetic manipulation over a whole lifespan, or across several generations, which would be infeasible using human subjects.
