Laboratory - Experimental Animals

Experimental and laboratory animals

Summary

  • Estimates of the total number of animals people use for experimenting on range between 40 million and 100 million animals (Table 1).

  • Japan and United States use more experimental animals than all other countries combined (Table 1).

  • Six countries using the largest numbers of experimental animals are Japan, United States, Britain, Canada, France and Germany (Table 1).

  • These six countries combined use around half the experimental animals worldwide (Table 1).


  • Over 2.6 million animals are used as experimental animals in Britain annually (Table 2).

  • Of experimental animals in Britain 80 per cent are rodents, ten per cent are fish, five per cent are birds, three per cent are mammals and less than one per cent are reptiles and amphibians (Table 2).

  • Experimenters in Britain annually carry out over 2.7 million experiments (procedures) on animals (taking 2000 as a typical year) (Table3).

Estimates for the number of experimental animals or laboratory animals are rough because some countries keep incomplete or no records. The United States for one does not count certain animals, many of them rats and mice. Some reports state that the US uses 18 million to 23 million animals per year.

Britain may keep more reliable and detailed data than any other country on numbers, species and the purpose experimental animals are put to. Some of these details are set out below. Britain is said to have the most stringent laws concerning laboratory animals. However, this strength is only relative to other countries.

Number of Procedures on Experimental Animals in Britain

Britain is said to keep more reliable and detailed data on animals used for experimental purposes than any other country. Laboratories used over five million experimental animals per year in Britain in the mid-1970's. The number dropped to 2.7 million in 1996 and stayed around that figure for several years. Table 3 shows the annual number of procedures by main purpose, a procedure being a single experiment on one animal. Because the same animal might undergo more than one experiment, the total number of procedures is greater than the total number of experimental animals (in Table 2). Around the year 2000 laboratories in Britain no longer made use of animals for testing cosmetics ingredients, finished products, or alcohol and tobacco products, and the use of chimpanzees, gorillas and orang-utans was proscribed.

Table 3. Number of Procedures on Experimental Animals in Britain in 2000.
Main Purpose Number of Procedures Percentage
Medicine 929,700     34
Research 872,800     32
Breeding 699,600     26
Toxicity testing 161,200       6
Education & Other 51,400       2
Total 2,714,700    100
