Animal experimentation in New Zealand
In NZ animals manipulated for claimed scientific purposes are categorised by the government into three groups — research, testing and teaching (RTT).
While we are opposed to most research, testing and teaching methods involving animals, not all cases involve animal experimentation therefore, we are not opposed to 100% of these cases.
For example, using a non-harmful tag and release research method on Kiwis for conservation purposes or vet nurses being taught how to handle animals correctly with someone’s dog or cat fall under the scope of being considered research, testing or teaching methods using animals in NZ. These examples would not be considered animal experimentation and we wouldn't be actively opposed to them.
What animals are used for
The use of animals for research, testing and teaching purposes is very broad and our position varies on each case depending on the scientific and ethical factors involved.
One of the easiest ways to illustrate the wide-ranging use of animals for claimed scientific purpose is by looking at Dr Ray Greeks nine uses of animals in science:1
Animals are used as predictive models of humans for research into such diseases as cancer and AIDS.
Animals are used as predictive models of humans for testing drugs or other chemicals.
Animals are used as “spare parts”, such as when a person receives an aortic valve from a pig
Animals are used as bioreactors or factories, such as for the production of insulin or monoclonal antibodies, or to maintain the supply of a virus.
Animals and animal tissues are used to study basic physiological principles.
Animals are used in education to educate and train medical students and to teach basic principles of anatomy in high school biology classes.
Animals are used as a modality for ideas or as a heuristic device, which is a component of basic science research.
Animals are used in research designed to benefit other animals of the same species or breed.
Animals are used in research in order to gain knowledge for knowledge sake
The first two are NOT scientifically valid and never have been.
Reasons 3-9 are scientifically viable. This doesn’t mean that they are the best scientific method or that they should continue being used. Although these uses of animals have to be acknowledged as scientifically viable, they are very old fashioned and outdated now and there are viable and humane replacements available that can be used instead.
#3 - Pig heart valves have worked in humans the past but today there are much better synthetic versions of heart valves that can be used instead (i.e. mechanical valves last a lot longer).
#4 - It is possible to harvest insulin from a slaughterhouse animal but today we have much better synthetically produced insulin with invitro technology.
#5 - Using animals to endeavour to find ‘basic principles of anatomy’ has in the past been possible using animals; for example, it’s possible to demonstrate that all mammalian hearts pump blood.
#6 - In the past it has been possible to practice certain techniques on animals to a greater or lesser extent, for example surgical residents could be taught technical skills like how to sew a vein to an artery by practising on a vein from or in a dog (the skill can be taught, at least in part in this fashion). Today we have sophisticated human-based models that can really provide a realistic situation for medical students.
#7 - Basic science research can be distinguished as being curiosity-driven rather than goal driven (applied research), for example looking at what a cell is and what it is made of. Using animals as a modality for ideas or as a heuristic device involves using animals to come up with ideas or concepts that could be of use to humans, for example, if a researcher is studying an animal or the tissue of an animal and from this, gets an idea about something in humans. It could be that the idea is similar to what the researcher was studying in animals or it could be more removed than that.
#8 - Animals can be used in research for animal diseases and drugs used in veterinary medicine (i.e. species-specific and even breed specific research). If researchers are using a different species to model the response of another, the research is no longer viable. This should be done to the same standard as human research, i.e. Pre-clinical studies should be conducted prior to ensure the safety of drug/product. These could be invitro techniques (using the cells and tissues of the species being studied), computer modelling and other non-harmful methods.
#9 - A researcher could conduct a highly invasive experiment on animals, not with the goal in mind of obtaining useful information, but just to obtain information regardless of whether or not it will be used for anything.
