Ethics and the use of laboratory animals
This website does not attempt to discuss the ethics of animal research in detail, but it lists specific resources that are relevant to those planning animal experiments. Harm-benefit assessment is discussed in a separate section. Implementation of the Three Rs, and assessment of a draft research protocol using the Three S's, help to reduce the potential harms and thereby influence the ethical review of a study. The PREPARE guidelines contain more resources to aid planning of animal research and testing.
Two pioneers within animal ethics must be mentioned:
The English philosopher Jeremy Bentham (1748-1832) wrote, in his Introduction to Principles of Morals and Legislation (1780):
'The day may come when the rest of animal creation may acquire those rights which never could have been withholden from them but by the hand of tyranny... It may one day come to be recognized that the number of legs, the villosity of the skin, or the termination of the os sacrum are reasons equally insufficient for abandoning a sensitive being to the same fate. What else is it that should trace the insuperable line? Is it the faculty of reason, or perhaps the faculty of discourse? But a full-grown horse or dog is beyond comparison a more rational, as well as a more conversable animal, than an infant of a day or a week or even a month old... The question is not, Can they reason? nor Can they talk? but, Can they suffer?”
The English physician and physiologist Marshall Hall (1790-1857), in his book Principles of Investigation in Physiology (1835), outlined five principles to govern animal experimentation, which are just as valid today:
- An experiment should never be performed if the necessary information could be obtained by observations
- No experiment should be performed without a clearly defined and obtainable, objective
- Scientists should be well-informed about the work of their predecessors and peers in order to avoid unnecessary repetition of an experiment
- Justifiable experiments should be carried out with the least possible infliction of suffering (often through the use of lower, less sentient animals)
- Every experiment should be performed under circumstances that would provide the clearest possible results, thereby diminishing the need for repetition of experiments.
These principles contain many of those embodied in the principle of the three Rs of Russell and Burch which were developed more than 120 years later.
Norecopa also endorses the principles embodied in a Culture of Care and a Culture of Challenge.
In the UK, the local animal welfare bodies also undertake ethical review and are called AWERBs (Animal Welfare and Ethical Review Bodies). Several presentations on ethics and ethical review can be downloaded from the website of a forum held in 2017: Putting Ethics into the AWERB
Delivering effective ethical review: the AWERB as a 'forum for discussion'
Ethical oversight..? Time to reflect on the meaning of ethical review on research involving animals (Hawkins & Jennings, RSPCA, 2019)
Animal Ethics Dilemma: An interactive learning tool for university and professional training.
The Research Council of Norway and the National Committee for Research Ethics in Science and Technology (NENT) collaborate with guidelines for ethical research. The Committee has produced general guidelines for research ethics in science and technology, which contain sections on the protection of animals used in research. There is more information on the Norwegian-language version of this page.
The Research Council is one of many funding bodies which has endorsed Joint European funding principles for research involving animals.

Peter Sandøe, Professor in Bioethics at the University of Copenhagen has written several articles on animal ethics. He is one of the authors of "Animal Ethics Dilemma", an interactive learning tool involving case studies for University and professional training, available free on the Internet, to help the user to obtain a better understanding of his/her own and others' ethical views.
The journal Food Ethics had a special issue on Veterinary Medical Ethics in March 2018, parts of which are relevant to laboratory animal science.
The Palgrave Macmillan Animal Ethics Series, including "The Costs and Benefits of Animal Experiments" by Andrew Knight.
"Forskningsbehov innen dyrevelferd i Norge" (Research needs within animal welfare in Norway). This Norwegian report from 2005 provided an introduction to definitions of animal welfare and an overview of current knowledge. It was financed by the Norwegian Research Council and pointed out research needs in this field.
