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.

The study of laboratory animal behavior has increased steadily over the last decade, with expanding emphasis on a variety of commonly used species. In the United States, this trend was initially focused on species for...

Crast, J., Bloomsmith, M. A., Perlman, J. E. et al. 2014. Abnormal behaviour in captive sooty mangabeys. Animal Welfare 23(2), 167-177.

The influence of several factors on abnormal behaviour was investigated in 46 singly housed sooty mangabeys (Cercocebus atys) (eight nursery-reared, 38 mother-reared), including self-injurious, self-directed, stereotypic locomotion, and faeces/urine-related behaviours (SIB, SDB, SL, FUR, respectively)...

Less, E. H., Kuhar, C. W., Lukas, K. E. 2013. Assessing the prevalence and characteristics of hair-plucking behaviour in captive western lowland gorillas (Gorilla gorilla gorilla). Animal Welfare 22(2), 175-193.

Non-human primates occasionally exhibit behaviours thought to occur only in captivity that are considered abnormal. In particular, hair-plucking behaviour occurs across many species of mammals and birds. This study was the first to assess the...

Coleman, K. 2012. Individual differences in temperament and behavioral management practices for nonhuman primates. Applied Animal Behaviour Science 137(3-4), 106-113.

This review will examine how individual differences in temperament might affect, or be affected by, behavioral management practices for captive primates. Measuring temperament may help us predict the outcome of social introductions. It can also...

Bortolini, T. S., Bicca-Marques, J. C. 2011. The effect of environmental enrichment and visitors on the behaviour and welfare of two captive hamadryas baboons (Papio hamadryas). Animal Welfare 20(4), 573-579.

The welfare of zoo animals depends on a combination of physical, social, dietary and other ecological characteristics of the captive setting. We analysed the influence of the transfer of an adult couple of hamadryas baboons...

Reamer, L., Tooze, Z., Coulson, C. et al. 2010. Correlates of self-directed and stereotypic behaviours in captive red-capped mangabeys (Cercocebus torquatus torquatus). Applied Animal Behaviour Science 124(1-2), 68-74.

The quantification of behaviours linked to anxiety or stress provides a powerful means to address applied questions related to the well-being of captive animals. This study explored correlates of two such behaviours: self-directed (SDB) and...

Egeler, J. L., Hoekwater, S., Hoffman, H. D. 2010. Monitoring program for the treatment of nonhuman primates with behavioral disorders. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 717 (Abstract #P113).

Maintaining the psychologic wellbeing of nonhuman primates housed in a laboratory setting is an important aspect in providing the best possible care for these animals. Nonhuman primates kept in captivity can begin to display abnormal...

Nelson, E. A., Keller, G. L., Mitchell, T. W. et al. 2010. A jugular bleeding technique in rabbits. Lab Animal 39(1), 17-22.

When studying pharmacokinetics in rabbits, researchers must often take multiple blood samples from conscious rabbits. Researchers usually collect these samples via the auricular vein, typically through a port or an indwelling catheter. The authors have...

Jarvis, K. A., Gould, J. E. 2007. Effects of a complex enrichment device on stereotypic behaviors, tool use, tool manufacturing, and activity budgets in captive western lowland gorillas (Gorilla gorilla gorilla). American Journal of Primatology 69(S1), 51. (30th Meeting of the American Society of Primatologists Scientific Program, Abstract #44)

As a way to reduce abnormal behaviors, specifically finger-sucking, hair-pulling, and reingestion/regurgitation, observed in two male gorillas at The ZOO Northwest Florida, a complex enrichment device that was contingent on the gorilla's ability to use...

Luzzi, M., Skoumbourdis, E., Baumans, V. et al. 2005. Collecting blood from rodents: A discussion by the Laboratory Animal Refinement and Enrichment Forum. Animal Technology and Welfare 4, 99-102.

The question was asked: "In your own experience, what is the least disturbing technique - from the subject's point of view! - of blood collection for rodents?" In summary, it is fair to conclude the...

Bassett, L., Buchanan-Smith, H. M., McKinley, J. et al. 2003. Effects of training on stress-related behavior of the common marmost (Callithrix jacchus) in relation to coping with routine husbandry procedures. Journal of Applied Animal Welfare Science 6(3), 221-233.

Using positive reinforcement, J. McKinley trained 12 common marmosets (Callithrix jacchus) to provide urine samples on request. The study then exposed the marmosets to mildly stressful, routine husbandry procedures (i.e., capture and weighing). The nonhuman...
