World Day for Laboratory Animals

World Day for Laboratory Animals is a worldwide holiday that calls for the preservation of the rights of laboratory animals. They are merely expendable material used by humans for experimentation and research. Animal rights organizations consider this a terrible act that needs to be stopped. The holiday is celebrated on April 24 every year.


The history of World Day for Laboratory Animals goes back to 1973, when it was founded by NAVS. NAVS proposed to develop innovative ways of testing products in various industries (especially pharmacology, nutrition and medicine, as these are the areas that require laboratory animals the most). The initiative was later supported by the A.D.I.

The holiday presents people with a choice: animal life or human life. Numerous animals are used for laboratory research, which are even specially bred for this purpose. Most of them are rats. Research involving them has led to the release of safe and effective medicines that have saved millions of lives. Because of this dilemma, the initiatives of animal advocates have never been realized.

Interesting facts

  • The first historical information about animal research dates back to the 2nd century B.C.
  • The DNA of mice and rats is more than 95% similar to human DNA, which explains the use of these animals in experiments.
  • Laboratory studies on animals allow us to observe changes in the body throughout their lives. If such experiments were conducted directly on humans, they would have to be kept in the laboratory for their entire lives.

How to celebrate

Talk to people you know who work in laboratories. Find out what they think about animal experiments. Read on the Internet what terrible diseases mankind has been able to find a cure for through animal research.

Spread the word about the holiday on social media. Ask users what they think about animal research.
