Refinement Database

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

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

Links to the full text for publications that appear in open access journals or are published on the AWI website are provided under the abstract.

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 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. Most publications older than 2010 can only be searched by keyword. 

Reading books to shelter animals combining auditory enrichment with human presence is increasingly used although its effects on animal welfare have not yet been investigated. This study compared the behaviour of single-housed shelter dogs and...

The environment provided for animals in captivity is less complex than its natural habitat, which generates a stressful condition. Environmental enrichment tries to meet the animals’ ethological and psychological needs. This paper aims to evaluate...

This great cool-down snack is ideal for group or singly housed swine or nonhuman primates (particularly in larger pen-style housing). This item can be customized for canines as well by modifying the liquid used and/or...

At the University of Oklahoma Health Sciences Center, NHPs may need to be singly housed for research purposes or veterinary care, and it can be challenging to keep them optimally enriched. This sometimes results in...

Dogs experience both acute and chronic stress when living in animal shelters. Current best practices recommend a variety of techniques for reducing stress such as enhanced human interactions including play or training, novel feeding strategies...

The endangered Asiatic lion (Panthera leo persica) is currently distributed as a single wild population of 670 individuals and ∼400 captive animals globally. Although the captive lions are major hope for the species’ long-term conservation...

The use of odors is a popular form of sensory enrichment, yet few studies have investigated the longer lasting effects of biologically relevant chemical signals like pheromones. Asian elephants (Elephas maximus) are unique because they...

The concept of the 3Rs (Refinement, Reduction and Replacement) has been used as a framework for improving the welfare of laboratory animals for the last half century. By establishing an animal-centric view on housing and...

It is sometimes essential to have an animal in the hand to study some of their ecological and biological characteristics. However, capturing a solitary, cryptic, elusive arboreal species such as the red panda in the...

The past few decades have seen increased interest in studies examining the welfare of elephants and animal–visitor interactions. One understudied area for both pursuits is the impact of public feeding interactions. Our study examined the...

Mouse deer are primitive, forest ungulates found in Asia and Africa. Both the lesser mouse deer (Tragulus javanicus) and the Philippine mouse deer (T. nigricans) are managed in European zoos, but inconsistent breeding success between...

The study aimed to determine whether artificial shade influences grazing behavior and body weight of pregnant female red deer. Two groups of pregnant does were grazed in enclosures with shade (WS, n = 23), or non-shaded enclosures...

This DIY snack is great for NHP and can be customized in a variety of ways.

This simple DIY training treat is great for NHP, swine, rabbits, rodents, and dogs. Note that dehydrated watermelon may resemble muscle tissue!

Despite the widely used application of standardized capture-handling protocols to collect blood and assess the physiological stress response, the actual sampling design (e.g., timing and the number of blood samples) often differs between studies, and...

It is increasingly required that non-human animals in laboratories are provided with adequate enrichment to promote the welfare of the animals. In a previous publication we showed that laboratory dogs intensively used the horn of...

A common goal of captive animal institutions is to create environments that allow for the most naturalistic behavior from their animals. Behavioral data is often used as a measure of how an animal is thriving...

Music therapy yields many positive health outcomes in humans, but the effects of music on the health and welfare of nonhuman animals vary greatly with the type of music played, the ethology of the species...

Worldwide, millions of dogs are held in kennels for extended periods of time and may experience compromised welfare. Enrichment, often using toys, is considered important to minimize the negative impacts of kennelling. However, the value...

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...

All capture methods impose animal welfare impacts, but these impacts are rarely quantified or reported. We present data from two wildlife capture studies that trialled new methods for capturing Bennett’s wallabies (Notamacropus rufogriseus) and red...

Automatic feeders have already been developed by different institutions and companies. Feedpods are a perfect example of an elaborate manufactured device. They are currently used in many institutions with satisfying results. One of the main...

This review paper is a synthesis of results from multiple studies that we have conducted over the past several years using similar methodologies to identify factors related to welfare of captive populations of elephants in...
