According to the latest Home Office figures more than 3.6 million animals were used in over 3.7 million experiments in the UK in 2010. This represents a 3% increase compared to 2009 on the number of experiments conducted and follows the first year of a slight decrease (of 1%) after 7 years of consecutive increases. This is an overall increase of 37% from the year 2000.
Animals used included:
2,659,491 mice, 293,905 rats, 13,586 guinea pigs, 10,138 rabbits, 3,727 dogs, 152 cats, 2,649 primates

The latest figures are only for 2008, in which just over 12 million animals were used, a small decrease from 12.1 million in 2005. France, the UK and Germany were the highest users of animals. The numbers reported are lower than national figures because they don’t have to report certain types of animals such as genetically modified (GM) animals.
Recent research by the BUAV and Dr Hadwen Trust suggests between 82 and 154 million vertebrate animals (115 million on average) may be used worldwide each year. 79% of countries don’t appear to publish the number they use. Based on our results, and controlling for the same uses and types of animals we estimate that the top 10 countries are United States, Japan, China, Australia, France, Canada, United Kingdom, Germany, Taiwan and Brazil.
