Question 1

NC3Rs Webinar: 3Rs advice for project licence applicants

Accepted Answer

All scientific work carried out in the UK under the Animals (Scientific Procedures) Act 1986 must be part of a programme of work authorised by a project licence. An important part of the ethical review and licensing process is ensuring that the principles of the 3Rs are robustly applied. In order to achieve this, when applying for a project licence, applicants are asked to detail how they have considered and applied the 3Rs to their research. To learn more about the 3Rs and how they can drive better science and animal welfare, view this video presentation from the NC3Rs.

Question 2

Focus and facts on the 3Rs

Accepted Answer

The Swedish 3Rs have a page with lots of multimedia resources on the 3Rs, including articles, films, and interviews.

They produce short pedagogic films about how advanced cell models and computer models can be used to replace and reduce animal experimentation.

Question 3

Identifying obstacles preventing the uptake of tunnel handling methods for laboratory mice: An international thematic survey

Accepted Answer

Identifying obstacles preventing the uptake of tunnel handling methods for laboratory mice: An international thematic survey

Abstract

Handling of laboratory mice is essential for experiments and husbandry, but handling can increase anxiety in mice, compromising their welfare and potentially reducing replicability between studies. The use of non-aversive handling (e.g., tunnel handling or cupping), rather than the standard method of picking mice up by the tail, has been shown to enhance interaction with a handler, reduce anxiety-like behaviours, and increase exploration and performance in standard behavioural tests. Despite this, some labs continue to use tail handling for routine husbandry, and the extent to which non-aversive methods are being used is currently unknown. Here we conducted an international online survey targeting individuals that work with and/or conduct research using laboratory mice. The survey aimed to identify the handling methods currently being used, and to determine common obstacles that may be preventing the wider uptake of non-aversive handling. We also surveyed opinions concerning the current data in support of non-aversive handling for mouse welfare and scientific outcomes. 390 complete responses were received and analysed quantitatively and thematically. We found that 35% report using tail handling only, and 43% use a combination of tail and non-aversive methods. 18% of respondents reported exclusively using non-aversive methods. The vast majority of participants were convinced that non-aversive handling improves animal welfare and scientific outcomes. However, the survey indicated that researchers were significantly less likely to have heard of non-aversive handling and more likely to use tail handling compared with animal care staff. Thematic analysis revealed there were concerns regarding the time required for non-aversive methods compared with tail handling, and that there was a perceived incompatibility of tunnel handling with restraint, health checks and other routine procedures. Respondents also highlighted a need for additional research into the impact of handling method that is representative of experimental protocols and physiological indicators used in the biomedical fields. This survey highlights where targeted research, outreach, training and funding may have the greatest impact on increasing uptake of non-aversive handling methods for laboratory mice.

Question 4

NC3Rs introductory training video on the 3Rs

Accepted Answer

Any aspiring in vivo researcher or animal technician should have a firm understanding of how following the principles of the 3Rs can drive better science and improved animal welfare.

This 18 minute video presentation has been created by NC3Rs to serve as a foundation for this understanding, and to encourage scientists and animal technicians to consider and implement the 3Rs throughout their careers.

It is also an excellent primer for anyone interested to learn more about the 3Rs in principle and practice.

The video includes:

Definitions and explanations of each of the 'Rs'
Practical advice on how to implement the 3Rs throughout a research project
Video case studies of 3Rs research
Information on the various resources the NC3Rs provides to support anyone working with animals in research
