The document provides guidelines from the Committee for the Purpose of Control and Supervision of Experiments on Animals (CPCSEA) on the care and use of animals for research. It discusses veterinary care, procurement, quarantine, housing, transportation, experimentation, and euthanasia. The objectives are to avoid unnecessary pain for animals and provide guidelines for housing, care, and experimental procedures. Veterinary care, quarantine for 1-6 weeks, and separation by species are recommended. Physical facilities, environment, food, bedding, and record keeping are also addressed. Anesthesia should control pain during experiments, and euthanasia aims to end pain and provide tissue for research.
