Title: The Ethics of
1The Ethics of Animal Research
2Animal Testing
- While controversial, it is an unavoidable fact
that animal research has allowed the development
of medicines and vaccines, surgical techniques
and advanced scientific understanding in many
areas throughout history
31726Stephen Hales first measures blood pressure
in a horse
1796Edward Jenner develops the world's first
vaccine, against smallpox. Critics express
skepticism, calling it ungodly to inoculate
people with material from cows.
41885Louis Pasteur develops a vaccine for rabies
vac cine / noun /From the Latin vaccinus,
meaning "from cows"
51881Louis Pasteur proves the germ theory of
disease by inoculating sheep against anthrax.
1902Robert Ross wins the Nobel Prize for his
work, using pigeons, showing how malaria is
transmitted

Jonas Salk
1964Dr. Michael DeBakey performs the first
coronary bypass surgery using techniques
perfected on animals

armadillos
1982Prions are discovered in hamsters.
Subsequent studies in mice have shown that these
misshaped, disease-causing proteins can be
inherited

10Number and kinds of animals used
- The Office of Technology Assessment estimates
that 17-23 million animals are used in the United
States for research every year. - The vast majority of these about 95 are
rats and mice specifically bred for research. - In 2010, there were more than 69,516 dogs and
25,560 cats used in research.
11- By comparison, wildlife biologists estimate that
over one million animals are killed every day by
automobiles over 365 million per year. - Dogs, cats, and non-human primates combined
account for less than 3/4 of a percent of the
total and their numbers has been declining for
nearly 30 years. - The number of dogs used in biomedical research
has declined 67 since 1973, and the number of
cats used in biomedical research has declined 63
since 1973.
12How can research results derived from animal
testing be extrapolated to humans?
- There are striking similarities between the
physiological systems of humans and various
species of animals. - Much of what we know about the immune system has
come from studies with mice, - Much of what we know about the cardiovascular
system has come from studies with dogs. - Research results from animals also provide the
information necessary to design human trials that
must be completed for legal approval of new
devices, drugs or procedures. - It is important to be able to gauge how a new
drug or procedure will affect a whole biological
system before using it on humans.
13 What assurances exist that stolen or lost pets
are not used in research?
- The vast majority of laboratory animals are
rodents specifically bred for research. - Nearly half of the dogs and cats needed for
research are also bred for that purpose. - Since state laws and local policies prevent many
animal pounds and shelters from providing dogs
and cats to research facilities, animal dealers
are the primary source for the other half of the
animals scientists require. - These dealers must be licensed by the United
States Department of Agriculture (USDA) and must
adhere to Animal Welfare Act standards of care.
14Animal Testing
- It is estimated that between 50 and 100 million
animals are used in research each year. - Some are purpose bred for testing but many are
still caught in the wild. -
15Measuring Pain and Suffering in Animal Testing
- The U.S. Department of Agriculture defines a
painful procedure as one that would reasonably
be expected to cause more than slight or
momentary pain or distress in a human being to
which the procedure was applied - Do you think this is a valid way to measure
suffering in animal tests?
16Measuring Pain and Suffering in Animal Testing
- In December 2001 the breakdown of experimental
licenses was - 39 mild
- 55 moderate
- 2 substantial
- 4 unclassified
- Does this seem a reasonable breakdown to you?
17Is Animal Testing Morally Right?
- The argument between pro-animal testing parties
and opponents to animal testing hinges on whether
it is ethical.
18Is Animal Testing Morally Right?
- Advocates for animal testing say
- Human life has greater intrinsic value than
animal life - Legislation protects all lab animals from
cruelty or mistreatment - Millions of animals are killed every year for
food, is medical research not a more worthy death - Few animals feel pain and are killed before they
suffer
19Is Animal Testing Morally Right?
- Opponents to animal testing say
- Animals have as much right to live as humans
- Strict controls have not prevented some animals
being abused, though such instances are rare - Deaths for research are unnecessary
- Animals suffer while they are locked up and how
do we know when they do and dont feel pain
20The Three Rs
- The guiding principles for the use of animals in
research are the three Rs - Replacement Use alternative, non-animal methods
to achieve the same scientific aim - Reduction Use statistical methods so that a
smaller number of animals are required - Refinement Improve the experiments so that
animals do not suffer
21Ethical Dilemmas
- Animal researchers say it will be impossible to
eliminate all animal tests but scientists are
always working on ways to minimise the suffering
of animals and to ensure as few animals as
possible will be required.
22Case Study Laika
- Laika, a mixed bred dog recruited into the
Soviet space program after being found on the
streets of Moscow. - Laikas mission would make her the first creature
to orbit the Earth in an attempt to study the
prolonged effect of weightlessness on a living
being.
23Case Study Laika
- Laika was 3 years old when she was launched on
the Sputnik 2 spacecraft on November 3rd, 1957. - She was secured in a special pressurised capsule
3 days before launch and provided with a high
nutrition gel for food and water.
24Case Study Laika
- Laika experienced minimal ill effects during
launch but her heart rate did rise to three times
its resting rate and she appeared to be quite
agitated, eventually calming down. - It appeared that weightlessness alone did not
cause major changes to the vital physiological
functions of a living creature. - This was good news for human spaceflight.
