Animal testing and experimentation refer to the use of animals for research purposes. In most circumstances, the key objective of these procedures involves evaluating the efficiency of medical drugs, advancing biological research, and studying diseases to mention a few. However, all these animal testing and experimentation procedures subject animals to pain and suffering, health issues, and physical and psychological distress, among other side effects. In the same parallel, animal rights are violated and their quality of life is greatly reduced. Use of animals for testing should, therefore, be banned or alternative methods deployed.

Support section 1 Animals are subjected to pain and suffering

When animals are imperiled to testing and experimentation, they languish pain and suffering (Carstens & Moberg, 2000, p.70). For instance, there are research procedures where animals used for testing are put in a chamber. This is a deadly experiment, which forces animals to inhale dangerous gases such as Carbon dioxide and in the process feel a lot of pain. Another case where animals languish pain and suffering is when fish and amphibians are dipped in water with tricaine. In a similar approach, Frey (2005), highlights that animals testing and experimentation reduce the quality of animal life, page 202. For example, a vivisection lab procedure indicated that the quality of rodent life is greatly diminishing. Scientists, on the other hand, conduct these procedures without caring about animal health and in the process reducing the quality of animal life. It is also important to assert that animal testing violates animal rights (Nicoll, 2011, p.307). Like humans, animals have moral rights and qualities. Animals feel pain the same way as humans. It is, therefore, morally correct to say that an animal's rights are violated because they suffer and feel pain when they are subjected to testing and experimentation.

Support Section 2: Animals are predisposed to a myriad of health problems

Laboratory animals are subjected to immense physical pain and distress. An example of laboratory generated distress on animals is the phenomenon of contagious unease. The cortisone levels in monkey are often high when they observe other monkeys being injected for blood collection. The heart rates and blood pressure increase in rats when they observe other rats being truncated (Akhtar, 2015, P.410). Whenever a rat is distressed it will develop severe inflammatory conditions and intestinal leakage which is a form of physical problem. Another example experiments were done on mice to come up with aortic curatives and due to the pain, they experience the noise levels can harm the blood vessels in animals in the laboratory.

In the last few years, scientists have often subjected animals to excruciating pain and distressing experiments. (Brieger et al. 2012, P. 5). For example, "Redox Regulation involves highly reactive molecules which emanate from the mitochondrial electron transport chain (ETC). The respiratory taking place in phagocytes ionizing radiation causes a damaging effect on the cell membranes, affects the metabolism, mental state, and even the life span of the animal. The animals will get mental stressors when ROS experiments are done on them by scientists.

Support Section 3: Alternatives to animal experiments

Russell & Burch (1), suggested the three Rs (Reduction, refinement, and replacement) as the widely accepted guiding principles on how humane animal testing should be carried out (Schuppli, Fraser & McDonald, 2004, P. 525). Replacement is defined as a technique of using non-sensitive materials during experiments. Some of these materials include "plants, micro-organisms, and endoparasites which could be an alternative to the use of Apes and animals as espoused by Russel and Burch" (Schuppli, Fraser & McDonald, 2004, P. 525). The main rationale behind proposing the three Rs is to reduce pain and distress arising from laboratory procedures. Finally, another example is ecological enrichment as an alternative proposed by scientists to alleviate abnormal behavior on animals by suggesting better techniques which will suit and fit in the condition's animals prefer.

With the growth in innovation and technology, there are better alternatives to animal testing (Itenberg et al. 2014 P.6). Tissue culture, the growth of isolated animal cells is widely preferred to due to it being accessible, and the tissues grown can be preserved for an indefinite period of time, and can also be replaced occasionally. It will also help to minimize the costs linked with replacing animals, housing them and feeding them during drug development. The new technology and medicines, more scientists will have solutions on how they can do humane experiments. For instance, transgenic animals will have their genes inserted into the DNA of one animal during experiments and it will help diversify the scope of their experiments without harming many animals.

The use of "in vitro" methods and cell co-cultures are other better alternatives to animal testing. A good example of in vitro techniques is the main liver tissue taken from a human (Pearson,1986, P. 560). Further, several studies have shown that vitro model techniques are able to offer more rapid, precise and, relevant information required by scientists as opposed to traditional methods of animal testing. Another example is mutagenesis and toxicity mechanisms which emanate from the similarity of genetic material in animals can also help replace animal tests.

Counterarguments Possible benefits of animals testing

Animals testing and experimentations have helped scientists to develop and discover new methods that help alleviate the pain and suffering animals have been experiencing (DeGrazia, & Rowan, 2012, p.201). Such medical procedures aimed at improving healthcare for the fact that the new methods such as refinement are a good strategy to reduce distress and suffering animals have been exposed to over years now. Consequently, it is through animal testing that researchers and scientists get to understand how the human body works (Robinson, 2005, p.4). Instead of using human beings to study medical drugs and to discover diseases, researchers are exerting more force to use more animals in their procedures. Animals can be modified as models and combined with the human genome in order to create a leeway for the discovery of how the human body reacts when subjected to diseases. Animals testing is also used to understand medical procedures to develop new drugs. According to Etuk (2010, p.130), scientists use animals in experimentation in order to understand the pathophysiology of diseases. Further, animals testing help in the discovery and development of new drugs and medical products. Animals are used to understand the level of toxicity medical drugs and to obtain a clue on how certain drugs work in the body.

Rebuttal 1

Scientists have come up with alternative methods such as refinement which assists in alleviating pain, distress, and suffering and enhances the welfare of the animal being used in the laboratory (Nicoll, 2011, P. 304). Most vivo experiments, the living animal is often dissected which causes pain, suffering, and distress since it is sentient. Replacement methods suggest the use of non-sentient techniques and Reduction advances the art of finding similar genetic compositions of animals with the view of reducing the number of animals subjected to testing.

Rebuttal 2

All animals have rights just like human beings (Portaluppi, Smolensky & Touitou, 2010, P.1920). The law insists that safety and humane experiments should be observed when they are subjected to experiments by scientists. There should be proper consideration when selecting species and assessing the best methods which will not cause pain and distress during the research. The use of animals for research should be approved and comply with the regulations by local, and federal. They must get proper sanitation, also proper housing, and feeding.

Rebuttal 3

Scientists should come up with drug and medical procedures using alternative methods (Halliwell & Gutteridge, 2015, P.30). For example, the introduction of chemistry in several types of kinds of species to carry chemical information used in the development of drugs by scientists. The use of animal species for drug development is now focused on specific areas. For example, rats and mice are used for cancer research, genome research, and drug screening.


The thesis of my discussion has been the use of animals for testing should be abolished or alternative methods are deployed. The reason is animals are subjected to excruciating pain and distress; they are predisposed to a myriad of health issues which reduce the quality of life. With the inception of innovation and technology in the field of medicine and research, the only solution will be to use alternative methods such as the three Rs a(reduction, replacement, and Refinement), in vitro techniques, and cell co-cultures. Animals have right just like human beings hence all the experiments required to be done on animals must conform to local, state regulations such as proper hygiene, feeding, and housing be provided on animals, and also use of non-sentient materials during experiments like primary liver extracted from human beings during vitro analysis experiments
