Facts and figures

Once a year, the Home Office releases the statistics on the numbers of procedures that have been completed during the previous year and the severity of those procedures

The number of procedures carried out as part of research programmes in MRC-owned establishments reported to the Home Office in 2018 was 268,032. This is 8% of the total of 3.52 million scientific procedures reported to the Home Office for that year. The number of scientific procedures by species and severity (Severity categories are described in the Annual statistics of scientific procedures on living animals Great Britain) can be found in the tables below. Breeding of genetically altered animals accounted for 46% of all procedures carried out.
