The ‘Annual Statistics of Scientific Procedures on Living Animals, Great Britain’ was published by the UK Home Office on the 19th of July 2018.
The figures show that 3.79 million animal experiments took place in Great Britain in 2017, a slight decrease of 4% compared to the previous year. Of these, 1.90 million (50%) related to the creation or breeding of genetically altered animals who were not used in further procedures, while the remaining 1.89 million experiments (50%) were experiments on animals for various purposes. These purposes were basic research (55%); translational/applied research (17%), regulatory tests (27%), and others (1%).
In 2017, there were increases in the number of experiments conducted on horses (up 18% to 10,600) and cats (up 4% to 198 experiments) in Great Britain. However, there were decreases in the use of other species, including mice (down 10% to 1.1 million), rats (down 2% to 234,000), non-human primates (down 17% to 2,960) and dogs (down 22% to 3,847).
Almost 700,000 experiments (32%) carried out in Great Britain in 2017 were deemed to have caused moderate or severe suffering to the animals involved; moderate or severe suffering was alse experienced by 5% of the genetically altered animals not used for further procedures. Moderate suffering is described by Directive 2010/63/EU as causing short term moderate pain or distress or long-lasting mild pain or distress to animals while severe suffering is described as causing severe pain or distress or long-lasting moderate pain or distress to animals.
