Research with animals: requirement, responsibility, welfare.

Abstract

Recognition of unacceptable cruelty to animals in pasttimes such as bull-baiting, dates in Britain from the early 19th century. The Society for the Prevention of Cruelty to Animals was founded in 1824. Several bills to curb cruelty were discussed in Parliament, and the Cruel and Improper Treatment of Cattle Act was passed in 1822. Other Acts have followed over the years. Cruelty in the form of painful scientific experiments, including dissection of living, conscious animals, vivisection, was proscribed by the Cruelty to Animals Act 1876. That Act required anyone wishing to experiment with animals to obtain a licence from the Secretary of State. Conditions for issue of licences were strict and remain so to this day. The Act is still valid, and is enforced by the Home Office, with its medical and veterinary Inspectors. The Cruelty to Animals Act 1876 allows experiments on animals under strictly controlled conditions. Experiments must have the clear objective of improving the welfare of man and/or animals. Benefits from experiments carried out under the Act have been enormous, covering every aspect of diagnosis, treatment, and prophylaxis in human and veterinary medicine. Coincidentally, the welfare of laboratory animals has also been greatly improved. There has always been some opposition to the use of animals in biomedical research. The subject is emotive but, by and large, discussion has been rational and within the law. In recent years, however, the morality of using experimental animals has been examined more closely. The possibility of replacing them by alternative methods has been investigated. Where these alternatives are applicable, they are used and further research on them continues. The questioning of animal experiments has emphasized the need to look constantly at animal welfare to ensure humane treatment of all animals, especially those restricted in a laboratory or on a farm. Attention has been drawn in this work to our existing laws protecting animals, but new legislation is being demanded, not only by some lay welfare groups but also by scientists. Hence, it has become very important to discuss various ways of ensuring animal welfare, including by legislation, especially with those knowledgeable in laboratory animal science and animal experiments.(ABSTRACT TRUNCATED AT 400 WORDS)
