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. 
Cavieres, G., Bozinovic, F., Bogdanovich, J. M. et al. 2023. Impact of prolonged chronic social isolation stress on behavior and multifractal complexity of metabolic rate in Octodon degus. Frontiers in Behavioral Neuroscience 17.

Social interaction can improve animal performance through the prevention of stress-related events, the provision of security, and the enhancement of reproductive output and survival. We investigated the effects of prolonged chronic social isolation stress on...

Yu, J. H., Brown, J., Boisseau, N. et al. 2021. Effects of Lupron and surgical castration on fecal androgen metabolite concentrations and intermale aggression in capybaras (Hydrochoerus hydrochaeris). Zoo Biology 40(2), 135-141.

To curb agonistic interactions in a bachelor group of three male capybaras (Hydrochoerus hydrochaeris), a single dose of leuprolide acetate (Lupron®) was used in an attempt to chemically sterilize the males. Concurrently, fecal androgen metabolite...

Insel, N., Shambaugh, K. L., Beery, A. K. 2020. Female degus show high sociality but no preference for familiar peers. Behavioural Processes 174, 104102.

Group-living animals vary in social behavior across multiple dimensions, including in the selectivity of social interactions with familiar versus unfamiliar peers. Standardized behavioral tests can be used to tease apart different dimensions of behavior. These...

Zemanova, M. A. 2020. Towards more compassionate wildlife research through the 3Rs principles: Moving from invasive to noninvasive methods. Wildlife Biology 2020(1), no page numbers.

Research in ecology and wildlife biology remains crucial for increasing our knowledge and improving species management and conservation in the midst of the current biodiversity crisis. However, obtaining information on population status often involves invasive...

Weber, L., Šmejkal, M., Bartoň, D. et al. 2019. Testing the applicability of tagging the Great crested newt (Triturus cristatus) using passive integrated transponders. PLOS ONE 14(7), e0219069.

Tracking individual animals with small-sized passive integrated transponder tags (PIT tags) has become a popular and widespread method, one which can be used for investigating life history traits, including dispersal patterns of small protected animals...

Donovan, M., Liu, Y., Wang, Z. 2018. Anxiety-like behavior and neuropeptide receptor expression in male and female prairie voles: The effects of stress and social buffering. Behavioural Brain Research 342, 70-78.

Strong social support can negate negative health outcomes – an effect defined as ‘social buffering’. In the present study, using the socially monogamous prairie vole (Microtus ochrogaster), we examined whether the presence of a bonded...

Chatigny, F., Kamunde, C., Creighton, C. M. et al. 2017. Uses and doses of local anesthetics in fish, amphibians, and reptiles. JAALAS 56(3), 244-253.

Local anesthetics are an integral part of routine pain management in mammals, yet their use is relatively limited in fish, amphibians and reptiles. These animals frequently undergo potentially painful surgical procedures and therefore could possibly...

Cary, C. D., Lukovsky-Akhsanov, N. L., Gallardo-Romero, N. F. et al. 2017. Pharmacokinetic profiles of meloxicam and sustained-release buprenorphine in prairie dogs (Cynomys ludovicianus). JAALAS 56(2), 160-165.

In this study, we evaluated the pharmacokinetic profiles of meloxicam and sustained-release (SR) buprenorphine in prairie dogs. The 4 treatment groups were: low-dose meloxicam (0.2 mg/kg SC), high-dose meloxicam (4 mg/kg SC), low-dose buprenorphine SR...

Tucker, R. D. 2017. Woodchuck College. Laboratory Animal Science Professional 5(2) (June), 33-36.

Marmota monax is a valuable laboratory animal species used in studies of Hepatitis B virus (HBV), food intake, obesity, hibernation, and circannual cycles. This article describes the woodchuck’s (also known as groundhog) natural behavior and...

Grippo, A. J., Ihm, E., Wardwell, J. et al. 2014. The effects of environmental enrichment on depressive and anxiety-relevant behaviors in socially isolated prairie voles. Psychosomatic Medicine 76(4), 277-284.

Social isolation is associated with depression, anxiety and negative health outcomes. Environmental enrichment, including environmental and cognitive stimulation with inanimate objects and opportunities for physical exercise, may be an effective strategy to include in treatment...

Merriman, D. K., Lahvis, G., Jooss, M. et al. 2012. Current practices in a captive breeding colony of 13-lined ground squirrels (Ictidomys tridecemlineatus). Lab Animal 41(11), 315-325.

The authors provide an update to their 2006 report on the successful large-scale captive breeding of the 13-lined ground squirrel (TLGS; Ictidomys tridecemlineatus) in their colony, now a single-source supplier of purpose-bred TLGSs for several...
