Our research

The vast majority of our research involving animals uses mice and rats. Here we detail the precise numbers and types of animal experiments carried out by the University, and on which types of animals.

The graphic below shows the numbers of procedures carried out by the University every year and on what species. The majority of our research involving animals is on mice and rats. The chart below explains the degree of suffering the animals experience, by showing the levels of severity of each procedure.  

The term procedure refers to any act that can cause an animal pain, suffering or distress. A procedure can be as mild as an injection or as severe as a surgical intervention where mortality can in rare cases occur. All experiments involve procedures but not all procedures are experiments.

  • The law defines the levels of severity animals experience as:
  • Subthreshold: where the animals do not suffer from an intervention.
  • Mild: causes short-term mild pain, suffering or distress.
  • Moderate: causes short-term moderate pain, suffering or distress or long-lasting mild pain, suffering or distress. 
  • Severe: animals are likely to experience severe pain, suffering or distress, or long-lasting moderate pain, suffering or distress
  • Non recovery. The animal is placed under general anaesthetic before the start of the procedure, and is humanely killed without ever regaining consciousness.

Most research involving animals at The University of Manchester is either mild or subthreshold.
