Animal research

Annual statistics

The University reports the number of animals that are used in research by species each year.

A 'regulated procedure' is one that:

  • Is carried out on an animal of a protected species
  • Is for a scientific purpose
  • May cause the animal a level of pain, suffering, distress or lasting harm equivalent to, or higher than, that caused by inserting a hypodermic needle in line with good veterinary practice.

All living vertebrates, excluding humans, and cephalopods, such as octopus, are protected by law. Embryonic and foetal forms are considered 'protected animals' in the last third of gestation, or incubation for egg-laying species. Larval forms of fish and amphibians are protected animals once they are capable of independent feeding. For example, zebrafish larvae become protected five days after fertilisation.

Procedures carried out on animals during early stages of development, before they reach protected status, may also be regulated under ASPA if the animals are kept alive beyond the point at which they become protected.

In 2018, the University carried out 194,174 scientific procedures involving animals. The vast majority of these involved rodents, predominantly mice and rats (79.9%), and fish (17.5%). Client-owned pet dogs were involved in studies at the Royal (Dick) School of Veterinary Studies aimed at improving care for sick animals. (See: Vitamin d in study spotlight).

Species Number Percentage
Rodents 154,922 79.9%
Fish 33,988 17.5%
Birds 3,691 1.9%
Agricultural species (cattle, sheep, pigs) 1046 0.5%
Animals monitored in the wild (sheep, deer, red squirrels, golden eagles) 447 0.2%
Frogs 72 <0.1%

Dogs (client-owned pets taking part in studies at the Royal (Dick) School of Veterinary Studies)

8 <0.1%

These figures are calculated each year based on data from annual returns that are prepared for the Home Office by every Project Licence holder.

Severity statistics

Each regulated procedure is assigned a severity which describes the animals experience.
