List of Animals that Often Used For Experiments – Animals are one of the objects most often used in experiments, this is due to the similarity of animal organs to humans.
Each year, more than 100 million animals are killed in the laboratory, based on data from the People for the Ethical Treatment of Animal (PETA). They are sacrificed for various scientific purposes.
Ethically, these animal-sacrificing experiments are often opposed, especially by activists. However, this is often done for the sake of human survival. Starting from drug trials, vaccines, to research on certain diseases.
Unless, if the experiment is carried out for the manufacture of cosmetics, skincare, fashion, and other product lines that are not an urgent need. Animal testing in this line can be replaced by other processes that do not sacrifice them.
Another case in the manufacture of vaccines or drugs. These chemicals are unlikely to be tested directly on humans because the risks and side effects are unknown. Therefore, researchers gave it to the animals first to see how they would react.
Seeing how great the sacrifice it is to human beings, we must know what animals are commonly involved in scientific experiments. Here are some of them!
Data from the Foundation for Biomedical Research (FBR) shows that 95 percent of the animals in the laboratory are mice, either black or white. They usually look for reactions to infections, diseases, vaccine tests, drugs, and other medical things.
There are several things that cause scientists to often use mice as experimental objects. First is the reason for convenience. Rats are small, easy to care for, and adaptable to the laboratory environment. In addition, they are cheap, non-aggressive and easy to breed.
Another reason why mice are often used in science experiments is that their genetic characteristics are similar to humans. Starting from body processes, organ systems, to the diseases they experience. This suitability can be used to answer a variety of research questions.
The next lab animal is rabbits, especially albino rabbits. These long-eared animals are commonly used for procedures that involve pain. For example, when testing the safety of drugs and medical devices or to measure the level of toxicity of chemicals.
To perform all of these procedures, rabbits are often tortured, poisoned, disabled, or even dead. Because it was considered torturing animals, in the 70s to 80s, animal lover groups proposed that experiments were carried out outside the biological environment (outside the animal’s body).
This pet is also used in science experiments. According to the American Anti-Vivisection Society (AAVS) website, dogs are often used to research heart disease, lung disease, cancer and orthopedics.
The reason scientists use dogs so much is that drugs and vaccines usually have to be tested on rodents and not rodents. This is to get a more accurate test result.
The breed of dog that is commonly used is the beagle because of its medium size and not being aggressive. They have been bred specifically for laboratory use and are usually less than one year old.
There is no doubt that primates are the animals most genetically similar to humans. However, these characteristics make it have advantages and disadvantages to be used as laboratory animals.
The advantage is that almost all primate organs and body systems are the same as humans. Digestive organs, metabolic system, brain, and the diseases they experience are quite similar to humans. If they are used for disease research and drug testing, the results can be more accurate.
On the other hand, primates have a high awareness of the world and of themselves because of their fairly developed brains. Whereas the main condition of animals used for experiments is that they must have a low awareness of the world, such as mice, dogs and rabbits.
However, because primate samples are needed, they are still involved in the laboratory. For example, for the manufacture of drugs and vaccines, transplant tests, to research on various chronic diseases. The types of primates that should not be used for experiments are gorillas, orangutans and chimpanzees.
