Science-based assessment of animal welfare: Laboratory animals
The use of animals in experimental research parallels the development of medicine, which had its roots in ancient Greece. The increasing demand for high-standard animal models, together with a critical view of the way animals are used, has led to the development of a multidisciplinary branch of science we now know as ‘laboratory animal science’. […]
The Three Rs in the pharmaceutical industry: perspectives of scientists and regulators
Six drug regulatory reviewers and 11 pharmaceutical industry scientists were interviewed to explore their perspectives on the obstacles and opportunities for greater implementation of the Three Rs (replacement, reduction, refinement) in drug research and development. Participants generally supported the current level of animal use in the pharmaceutical industry and viewed in vitro methods as supporting, […]
Classifying the severity of scientific animal use: a review of international systems
Severity classification systems (ie pain scales, categories of invasiveness, degrees of severity etc) are used to classify the adverse effects experienced by animals used for scientific purposes. Currently, eleven countries use severity classification systems. These systems have developed in various ways, depending on each country’s process for overseeing the use of animals in science, as […]
An illustration that statistical design mitigates environmental variation and ensures unambiguous study conclusions
This paper highlights the essential need for appropriate statistical design and randomisation in laboratory animal studies. Using an example of a 21 day weight gain study in mice, we show that without the use of an appropriate statistical design and randomisation, incorrect conclusions may have been drawn. We used an experimental design that allowed comparisons […]
Painful dilemmas: the ethics of animal-based pain research
While it has the potential to deliver important human benefits, animal-based pain research raises ethical questions, because it involves inducing pain in sentient beings. Ethical decision-making, connected with this variety of research, requires informed harm-benefit analysis, and the aim of this paper is to provide information for such an analysis. We present an overview of […]
The use of databases, information centres and guidelines when planning research that may involve animals
In many countries scientists planning research that may involve the use of animals are required by law to examine the possibilities for replacement, reduction or refinement (the Three Rs) of these experiments. In addition to the large number of literature databases, there are now many specialist databases specifically addressing the Three Rs. Information centres, with […]

Progress in assessing animal welfare in relation to new legislation: Opportunities for behavioural researchers
Recent revisions to international legislation and guidelines on the care and use of animals in research and testing emphasise the importance of minimising suffering and improving welfare. Achieving this requires effective systems for recognising, recording, analysing and assessing animal behaviour, in order to identify relevant indicators of pain, suffering, distress or lasting harm so that […]
