The process of animal testing for experimentation purposes dates back centuries in the 2nd and 4th century BCE. Animals have been used repeatedly throughout the history of biomedical research which are commonly easy to breed animals such as pigs, goats, mice, sheep, rats and etc. There were many scientists that revolutionized the field of biomedical research. To name a few, According to Pasteur(1864) who was a French chemist and microbiologist that was renowned for his breakthroughs of vaccination, pasteurization, fermentation. By performing his research regarding the germ theory, he proved it by demonstrating it by inducing anthrax in sheep.

The Three Rs (3Rs) are fundamentally controlling standards for moral use of creatures in testing for exploration or experimentation purposes. The 3Rs are; Substitution, Decrease and Refinement. Substitution alludes to the favored utilization of non-creatures techniques over creature strategies. Lessening alludes to techniques that acquires data from less creatures. Finally, Refinement alludes to techniques that assuage or minimize potential agony, enduring or any misery. The 3Rs really have a more extensive degree than basically reassuring option strategies to creature testing, however its point in genuine certainty is to enhance creature welfare and logical quality. Regardless of the constructive outcome of the regular routine of 3Rs, numerous nations have reported expanding utilization of creatures, for example, mice, rats, rabbits, and other simple to breed
