List of Animals that Often Used For Experiments

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!

1. Rat

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.

2. Rabbit

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).

3. Dog

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.

4. Primates

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.…

Craziest Animal Experiments in History

Craziest Animal Experiments in History – Experiments are one of the common things that scientists often do, experiments using animals are one of the most frequently carried out experiments.

Experiments became commonplace. When scientists create something new, they will continue to experiment until they get the right results. It is not uncommon for these experiments to involve living things such as animals to be used as guinea pigs.

But what is called an experiment, it doesn’t always work. And when this experiment fails, then the victims are these animals. Sadly, it’s not uncommon for animals to die in painful ways because of these failed experiments. Here are eight of the craziest animal experiments ever!

1. Research on the sexual predisposition of turkeys

In the 1960s, two researchers from Pennsylvania State University conducted a study on sexual predisposition in a turkey. So when the mating season arrives, they put the imitation female turkey down and let the male turkey see it to see how the male is reacting.

Instead of refusing, the male turkey approached the female KW turkey and tried to mate with her. Do not stop there, these researchers began to take several parts of the female turkey gradually to determine the reaction of the male turkey.

Starting from taking the tail, legs, wings, and even the body, leaving only the head supported by wood. As a result, the feeling of the male turkey is still the same as before.

2. Lazarus project

Trying to revive a dead creature is an impossible job, even for today’s technology. But believe it or not, there was a researcher who tried it in the 1930’s. He is Robert E. Cornish, a researcher from the University of California, Berkeley.

Robert believes that he can revive a dead creature as long as the creature does not experience organ damage. The research began by making four dogs asphyxiated and then dying, and placing them in a strange machine that functions to circulate blood. In order for the experiment to be successful, Robert E. Cornish then injected a mixture of adrenaline and anticoagulant.

The result? Two of the four dogs died, while the other two managed to live for months with severe brain damage and blindness.

3. The closeness of humans and dolphins

As a rule, living things will mate with living creatures of the same species with it. But who would have thought that there are animals that have mated with humans. In 1967, dolphin researcher John Cunningham Lilly tried to teach dolphins to speak English.

First, Lilly transforms a room into a pool, then asks her assistant named Margaret to stay and teach a male dolphin named Peter English. As time went on, Peter became closer to Margaret, even Peter tried several times to marry Margaret.

For the sake of experimentation, Lilly asks Margaret to fulfill Peter’s sexual needs. In the end, their relationship ended tragically. After the research was completed, Margaret left Peter and broke his heart, then ‘committed suicide’ by refusing to go up to the surface to take a breath.

4. Monkey head transplant

Although difficult, transplants are something that happens quite often nowadays. But it’s a different story if you go to 1963. Back then, transplants were not a common procedure, and researchers still wondered if they could do it?

To answer that question, a research team from Case Western Reserve University School of Medicine in Cleveland, Ohio beheaded two monkeys, and then transplanted the heads of the monkeys into other monkeys. Well, the monkey did manage to live again for one day with a paralyzed condition, before finally dying the next day.

5. Zombie paint

So far, we only know that zombies only exist in movies, but who would have thought that zombies had also lived in the real world. Don’t worry, this zombie is not a living corpse that will attack humans, but a dead cat that has been successfully ‘revived’. It is Karl August Weinhold, a researcher from Germany who believes that the human brain is like a battery which is attached by a set of ‘wires’ in the form of the nervous system.

To prove it, Karl then conducted an experiment in 1817. He killed a cat, and injected certain fluids into his body. For 20 minutes, the dead cat raised its head, opened its eyes, and even jumped around like a live cat.

6. The two headed dog

If the experiments conducted by Karl August had gone badly, it had nothing to do with what Charles Guthrie was doing. In 1908, this scientist from the United States killed a dog, cut off its head, then transplanted it to another dog. Guthrie did manage to create the world’s first two-headed dog, unfortunately the poor dog only lived for 26 minutes.…
