Refinement Database

Database on Refinement of Housing, Husbandry, Care, and Use of Animals in Research

This database, created in 2000, is updated every four months with newly published scientific articles, books, and other publications related to improving or safeguarding the welfare of animals used in research.

Tips for using the database:

  • This landing page displays all of the publications in the database.
  • Use the drop-down menus to filter these publications by Animal Type, Setting, and/or Topic.
  • Clicking on a parent category (e.g., Rodent) will include publications relating to all the items in that category (e.g., Chinchilla, Gerbil, Guinea Pig, etc.).
  • You may also add a keyword to further narrow your search.
  • Please note that at this time, only publications dated 2010 or later (with some exceptions) can be filtered by Animal Type and Topic, and only publications dated 2020 or later (with some exceptions) can be filtered by Setting. Most publications older than 2010 can only be searched by keyword. 
Reupke, V., Walliser, K., Perl, T. et al. 2017. Total intravenous anaesthesia using propofol and sufentanil allows controlled long-term ventilation in rabbits without neuromuscular blocking agents. Laboratory Animals 51(3), 284-291.

The aim of this study was to evaluate a total intravenous anaesthesia (TIVA) protocol using propofol and sufentanil without neuromuscular blocking agents (NBAs) for a non-recovery lung pathology study in rabbits including 10 h of...

Williams, M. D., Long, C. T., Durrant, J. R. et al. 2017. Oral transmucosal detomidine gel in New Zealand White rabbits (Oryctolagus cuniculus). JAALAS 56(4), 436-442.

Handling and restraining rabbits for routine procedures may be impossible without prior sedation, result in unnecessary stress or injury to the rabbit or handler, and increase experimental variability. Parenteral administration of sedatives can cause stress...

Pereira-Figueiredo, I., Costa, H., Carro, J. et al. 2017. Behavioural changes induced by handling at different timeframes in Lusitano yearling horses. Applied Animal Behaviour Science 196, 36-43.

Recent interest has focused on the advantage of intensely handling young horses, as a good tool for improving emotional reactivity and thence trainability. Its effectiveness remains controversial, suggesting it might depend on the right timeframe...

Vullo, C., Carluccio, A., Robbe, D. et al. 2017. Guaiphenesin-ketamine-xylazine infusion to maintain anesthesia in mules undergoing field castration. Acta Veterinaria Scandinavica 59(1), 67.

In order to determine whether a combination of guaiphenesin, ketamine and xylazine can induce safe and satisfactory anaesthesia in mules undergoing field castration, eight healthy adult intact male mules were employed. They were premedicated with...

Ali, A. B. A., Gutwein, K. L., Heleski, C. R. 2017. Assessing the influence of upper lip twitching in naive horses during an aversive husbandry procedure (ear clipping). Journal of Veterinary Behavior 21, 20-25.

When engaging in procedures that horses may find aversive, restraint methods are often used to help ensure safety of both horse and handler. Twitching is a common restraint method, but its use is sometimes considered...

Watson, J., McDonnell, S. 2016. Effects of three non-confrontational handling techniques on the behavior of horses during a simulated mildly aversive veterinary procedure. Journal of Veterinary Behavior 15, 85-86. (12th International Society of Equitation Science (ISES) Conference Abstract)

During mildly aversive healthcare procedures, horses often exhibit behaviors that may interrupt or prolong the procedure. Handler response often includes increased restraint and/or positive punishment, which can be ineffective or counterproductive. The purpose of this...

Bode, A. E., Barber, H. 2014. Use of vinyl nonadhesive tape as an alternative for positioning rodents in small animal imaging. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 597-598. (Abstract #P185).

Specific positioning for different imaging modalities is essential in our small animal imaging core. While we have different animal holders designed to position the animal inside the MRI, additional securing of the animal to the...

Pater, C. S. 2013. Rabbit hypnosis as a form of mild restraint: A forgotten method. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 615 (Abstract #PS42).

Rabbit hypnosis or “trancing” was a common restraint technique used for minor procedures such as: nail clipping, tooth trimming, eye exams, and subcutaneous injections. In years past the technique was originally used on pet rabbits...

Cruden, J., Bester, J., Baines, N. et al. 2013. Will a more consistent handling method lead to a calmer rabbit? Animal Technology and Welfare 11, 127-130.

The authors describe various methods of handling and restraining rabbits, and propose that while many methods are appropriate, rabbits respond better if only one method is used consistently.

Swennes, A. G., Alworth, L. C., Harvey, S. B. et al. 2011. Human handling promotes compliant behavior in adult laboratory rabbits. JAALAS 50(2), 41-45.

Routine laboratory procedures can be stressful for laboratory animals. We wanted to determine whether human handling of adult rabbits could induce a degree of habituation, reducing stress and facilitating research-related manipulation. To this end, adult...

Hawkins, P., Burn, C., Hurst, J. et al. 2011. Report of the 2010 RSPCA/UFAW rodent welfare group meeting - The effect of husbandry on welfare and promoting good practice. Animal Technology and Welfare 10(2), 105-114.

The RSPCA/UFAW Rodent Welfare Group holds a one-day meeting every autumn so that its members can discuss current welfare research, exchange views on rodent welfare issues and share experiences of the implementation of the 3Rs...
