Why are experiments always done on mice? Here are the reasons

Must read

By grimm, 95% of animal research US is conducted on rodents; In the European Union, this rate drops to 79%. However, we do not have enough data to say with certainty how many mice or rats were used in the studies.

while United States Department of Agriculture (USDA) tracks the many species (birds, dogs, cats, and rabbits) used for testing, and no organization in the US maintains a complete list of all species. Mice or rats used in the study. By 1965, the number of academic citations featuring these rodents had quadrupled, while many other subjects (dogs, cats, guinea pigs, rabbits) were studied at a fairly constant rate. So why are experiments being done on these mammals?

Some reasons are practical: They are small, easy to grow and inexpensive. When testing many subjects it can be helpful to study more than one generation at a time and doing this with dogs will be more problematic. Besides, they are mammals, so we have some common features with them. Also noteworthy is their ability not to inherit the negative effects of raising siblings. almost identical genetic makeup. Speaking of genetic information, it can be changed very easily in mice and rats.

Others reasons “routine”: so much research has been done on mice that much of the scientific and pharmacological development has been based precisely on the latter’s work. Therefore, if a new project wishes to refute or update the thesis of the previous one, it will once again rely on these rodents for more conclusive results.
