Name the different ethical views on use of animals for experimental research.
Disapprovers, approvers and approvers with reservations
Describe how the public perception of Animal experimentation overall relate to the ethical theories of Utilitarianism, Contractarianism and Animal Rigths View.
- Contractarianism = Since animals can‘t partake in contracts, their welfare is considered less directly, but public perception can demand ethical treatment if society collectively values animal well-being & views cruelty as socially unacceptable.
- Utilitarianism = Public support is often justified if the potential human benefits (e.g., medical advances) are seen to outweigh the animal suffering involved
- animal rights view = advocate for alternatives & argue that animal experiments violates rights of animals to be free from harm, pain or suffering.
Describe how 3Rs and a Culture of Care combined can promote animal welfare and support staff job satisfaction.
The 3Rs are an important and integrated part of culture of care. A high level of the 3R appliance will both reduce the number of animals (replacement and reduction) and the harm to the animals (refinement), and thereby also increase the job satisfaction of caretakers and other staff working with the animals.
- Culture of care:
o corporate & personal commitment to improve animal welfare & scientific quality
o aims at improving both animal and human wellbeing
o Part of a Culture of Care is to implement 3R to the highest possible degree
o high level of 3R compliance reduces emotional strain on animal care staff
o culture of care is not directly mentioned in the EU directive
o animal welfare body promotes culture of Care & compliance with 3 Rs
Discuss the use of live animals for training and teaching purposes in Laboratory Animal Science in courses such as the one, you are taking right now.
Vets and doctors, f.ex. use animals for educational reasons
All this are considered beneficial, and could also be argued to have a economic interest.
- educational value: provide students with hands-on experience in handling, care & experimental procedures
- ethical considerations: Utilizing animals in educational settings must adhere to ethical guidelines & regulations to ensure that welfare is prioritized.
- incorporate alternatives to live animals in teaching whenever feasible. Alternatives include stuffed animals, computer simulations, anatomical models & videos (practical advantages: cheaper & ability to simulate a wider range of scenarios)
Explain how the pharmaceutical industry and academia can inform the public on animal experimentation and discuss the benefits of such openness and transparency.
- public engagement events (open days, seminars, public lectures) educate public about role of animals in research & ethical considerations involved
- online resources
- Collaborating with animal welfare organizations foster dialogue & understanding between stakeholders with differing perspectives on animal experimentation
- enhance public trust in the ethical review and oversight of animal experimentation
Present the 3 Rs, the purpose of the 3R and give an example on how the principles of the 3 Rs are not always compatible.
- Replacement, Reduction and Refinement
- Purpose: minimizing suffering
Replacement:
- methods which aviod/replace the use of animals
- substitution/absolute replacement/relative replacement
- example: In toxicology, we have cell-based assays & computer models that can predict the toxicity of substances without the need for animal testing
Reduction:
- methods which minimize the number of animals used or the number of experiments
- example: employ power analysis to determine min. sample size required to detect significant effects
Refinement:
- methods which minimize suffering and improve welfare
- example: invasive imaging methods (e.g., MRI) allow to study brain activity in animals without invasive procedures that cause pain or distress
Imcompatibility:
Reduction and refinement:
- not always compatible, as using fewer animals may risk increasing the strain on each individual animal
- Replacement: vaccine efficacy tests in in-vitro assays don’t fully replicate the complex interactions that occur within a living organism’s immune system
- Refinement: non-invasive methods may limit the extent to which something can be studied.
Present and discuss different viewpoints on/definitions on the nature of Animal welfare and discuss methods to measure/evaluate animal welfare.
- Health and Biological function
o ensures that animals are free from pain, disease, injury & that their basic biological needs are covered
o emphasizes physical health & the ability of animals to perform natural behaviors essential for survival - natural living
o allowing animals to live in environments that are conducive to their natural behaviors and preferences.
o provide animals with opportunities to engage in species-specific behaviors & live in environments that resemble their natural habitats.
o Example: Enrichment activities aim to stimulate natural behaviors, such as foraging, exploration & social interaction, to enhance well-being of animals. - affective states
o emphasizes emotional & psychological well-being of animals, recognizing that they can experience positive/negative emotions
o observing signs of stress or distress, such as stereotactic behaviors, aggression, or withdrawal provides insights into their affective states. - Methods to measure animal welfare:
o Behavioral observations: activity levels, social interactions & natural behaviors, …
o Physiological measures: heart rat, cortisol levels & immune function
Present the Five Freedoms and explain how these apply to laboratory species.
1) freedom from hunger and thirst
2) freedom from discomfort
3) freedom from pain, injury and disease
4) freedom to express normal behavior
5) freedom from fear and distress
How they apply:
- they combine the 3 view points of wellfare, and can be used as a guide on how to avoid unnecessary suffering (originally meant for farm animals)
1) by access to water & a sufficient diet
2) by providing an appropriate environment.
3) by prevention or rapid diagnosis +
treatment. Obviously, this freedom is not always met, as we intentionally subject animals to pain, injuries & diseases. We need to reduce these effects whenever possible & never accept more pain, injury or disease than absolutely needed. We should always set out humane endpoints to make sure that no unnecessary pain, injury or disease is forced on the animals. Refinement + compassion for the animals is key.
4) by providing sufficient space, proper facilities & appropriate socialization. Environmental enrichment (social, structural & support physical and cognitive activities) is mandatory
5) by ensuring conditions/treatment, which avoid mental suffering. This freedom can’t be always met since laboratory animals are subjected to procedures evoking fear and distress.
Describe the importance of good animal welfare including its effect on scientific outcomes as well as for ethical reasons.
Utilitarian:
- animal welfare matters since animals are sentient beings capable of suffering. Thus it is our moral duty to limit/eliminate suffering
Animal rights:
- Animals have intrinsic value, and must never be used as tools, and their welfare is just as important as ours.
Contractarian:
- We do not have any direct moral obligations towards animals, and animal welfare matters only if a moral agent such as the person themself cares for animals and are willing to include animals in an agreement
In EU the predominant view is utilitarian (in DK same, but with some animal rights perspective as well). It is clearly stated in the EU directive that animals have intrinsic value.
Scientific reasoning
- translatability, reproducibility
- stress can affect outcome of a study, and a lot of systems (immune, cardiovascular, reproduction)
- fear and pain will affect animal behavior
Explain what is meant by “A Culture of Care” and discuss why it is important to promote a Culture of Care.
- Caring for the welfare of both animal and staff
- implementing the 3 Rs
- will also reduce staff stress and support job satisfaction
The animal welfare body
- drive a culture of care
- collaborating with senior management
- encourage contributions from staff
- encourage collaborations between scientists and care staff
- communicating on 3Rs, animal welfare, ect.
Give examples on homepages where information on laboratory Animal Science, Laboratory Animal Care and 3R can be found. Discuss why you think it is important to continuously stay updated on how to optimise animal welfare during housing, handling and procedures.
- “National centre for the replacement, refinement and reduction of animals in research”
- “Three Rs microsite”
- “Danish 3R-center”
- it is important to keep updated because
o New scientific technologies offer alternative methods or refinement that improve animal welfare & reduce need for invasive procedures
o ensures compliance with current standards and best practices
o Enhances reproducibility
o reflects a commitment, compassion, respect to animals
o Maintaining public trust and support
Discuss the 3Rs and why it is important to continuously improve the level of Refinement in animal experimentation.
According to the EU directive, the animal welfare should always be given highest priority - refinement ensures that animal welfare is always prioritized
Both legal and moral responsiblity. Also enhance public trust
Explain the purpose of a Harm/benefit analysis in animal experimentation and give examples on parameters included in a Harm/benefit analysis.
- You must perform a HBA prior to granting a license, to assess wether the harm to the animals (suffering, distress and pain) is justified by the expected outcome of the experiment (may ultimately benefit either humans, animals or the environment)
Parameters
THE HARM
- Animal rights
- Animal welfare (5 freedoms is a good start)
- Quality of research (if the data is useless, then the use of animals are irresponsible and lack of respect, could also lead to misleading results, which are potentially harmful)
- Human harm (caretakers/technicians may be negatively affected by the procedures, if it is obvious that the animals are harmed in some way. Also killing the animals after the study may also have negative effects on the mental health of caretakers)
THE BENEFITS
- Expected outcome (improvements in the fields of human health, wildlife, or environment)
- Education
- Economics
- Bateson’s decision cube integrates 3 dimensions:
o likelihood of benefits: How realistic is it that we obtain important results?
o benefit: How high is the benefit?
o harm to the animals: low or high?
Discuss the importance of being able to justify on ethical grounds, the decision to use living animals, including the choice of models, their origins, estimated numbers and life stages. Describe the ethical and welfare factors influencing the choice of an appropriate animal or non-animal model.
- to justify the use of living animal is an moral obligation & legal requirement
- improves the mental wellbeing of the staff
- chosen species should provide the most accurate data possible
- use purpose-bred animals to ensure health, genetic quality & well-being
- Use minimum number of animals necessary to achieve statistically significant results.
- Life Stages: significantly impacts outcomes of research & welfare of the animals. E.g., using embryos or larvae in place of adult animals sometimes reduces suffering.
- ethical & welfare factors determining the model
o relevance to research questions: Ensure the model accurately reflects the biological and physiological aspects of the human condition being studied.
o compliance with the 3Rs
o opt for species less likely to experience distress from procedures
Describe and explain the challenges when performing a Harm/Benefit analysis of a study using live animals.
- The harms of a study are always more or less certain, whereas the benefits are not - should harms, that are certain, have more weigh than benefits that are probable?
- Can human and animal suffering be compared? Do humans matter more than animals?
- No clear definition of what constitues a harm
- subjectivity of interpretation: subjective assessment of harm & benefit
A HBA includes both ethical and scientific considerations and is not as simple as may seem
Explain and discuss different ethical views on use of animals for experimental research: Approvers.
- Aka. contractarianism
- Morality is based on agreement (as long as society allows for animal use, it’s not a problem) - this contract is established between rational persons (“moral agents”) capable of discussing such an agreement
- in this view, animals and even newborn babies have no rights, unless capable people negotiates the rights for them
Explain and discuss different ethical views on use of animals for experimental research: Disapprovers.
- Aka. Animal rights view
- Animals have rights, that must not be denied
- Good results cannot justify evil means
- It is not possible to point out a single criteria for moral exclusion of sentient animals, which would exclude all humans –> all sentient animals (as well as humans) have an absolute right to be treated with respect
Explain and discuss different ethical views on use of animals for experimental research: Approvers with Reservations.
- Aka. Utilitatianism
- “Create all the happiness you are able to create - remove all the misery you are able to remove”
- “The needs of the many outweigh the needs of the few/one”
- concerned with the suffering of the animals, which must be counterbalanced by the benefits of the experiment (==> more wellfare than before)
