Liveanimal

Live animal is a term used to identify an organism that is living and active at the time of observation, testing, or handling, as opposed to preserved specimens, cadavers, or tissue samples. In practice, the term covers a wide range of species, from laboratory mice and fish to farm livestock and companion animals.

In science and medicine, live animals are used for fundamental biology studies, disease modeling, pharmacology, and clinical training. Use is governed by ethical review and welfare regulations intended to minimize pain and distress. Many countries require institutional oversight, adherence to the 3Rs—Replacement, Reduction, and Refinement—adequate housing, veterinary care, and the use of anesthesia and analgesia where appropriate.

In agriculture and commerce, live animals are kept for breeding, work, or food supply, and are moved through markets and transport systems. Welfare standards address housing, feeding, handling, and humane transport; enforcement varies by country and region, with inspections and certifications common in many jurisdictions.

In wildlife research and conservation, live animals may be captured briefly for tagging or monitoring, or observed in their natural habitat. Ethical considerations emphasize minimizing impact, obtaining permits, and ensuring non-lethal methods whenever feasible.

Public discussion surrounding live animals encompasses animal welfare, animal rights, and the safety of products derived from animals. Regulatory frameworks and professional guidelines aim to balance scientific and economic needs with compassion for animal well-being.
