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. 

Understanding individual responses to stress is a key aspect of maintaining optimal animal welfare. This is especially important where animals are being kept in sub-optimal environments or where the species may not clearly demonstrate stress...

Specifically designed restraint chairs are the preferred method of restraint for research studies that require NHP to sit in place for sustained periods of time. In light of increasing emphasis on refinement of restraint to...

Performance of abnormal repetitive behavior (ARB) is noted in many captive wild species. ARB can be categorized into 2 basic forms: those whose aim appears to be to compulsively reach an inappropriate goal and those...

Positive reinforcement training with cats is a useful tool for improving the human-animal bond, treating behavior problems, and teaching novel tasks. In part 1 of this study, 3 cats were assessed for extinction to a...

The act of grooming has been found to greatly decrease stress, heart rate, and cortisol levels in nonhuman primates; this decrease in stress and cortisol is seen in the animal being groomed, as well as...

Non-human primates have complex relationships with conspecifics and also other animals with whom they share their habitat in the wild. Some primates, such as capuchin monkeys (Sapajus apella) and squirrel monkeys (Saimiri sciureus), naturally associate...

Recent research in nonhuman animals highlights the exciting possibility that performance on cognitive bias tasks might indirectly measure an individual’s subjective, affective state. Subjects first learn to perform a conditional discrimination task with two differentially...

Many pet cats are kept indoors for a variety of reasons (eg, safety, health, avoidance of wildlife predation) in conditions that are perhaps the least natural to them. Indoor housing has been associated with health...

Primates are highly social animals and appropriate enrichment is required to ensure their psychological well-being. Mirrors are sometimes used as social or sensory environmental enrichment. In this paper we investigate the suitability of mirrors as...

The success of breeding primates in captivity has led to a surplus number of animals in collections. This review examines published journals and key books to investigate the various methods of primate population control. Hormonal...

Cats are often subjected to minimally painful or forced procedures during routine clinical practice, which can be poorly tolerated, leading veterinary surgeons to need to offer physical restraint, usually aided by an assistant. The aim...

The use of enzyme immunoassays (EIA) for the non-invasive measurement of glucocorticoids provides a valuable tool for monitoring health and welfare in sensitive species. We validated methods for measuring fecal glucocorticoid metabolites (FGM) using the...

Monkeys first arrived in the Comparative Biology Centre (CBC) at Newcastle University in 2000. They were housed in three small separate units consisting of steel and wooden cages. In 2011 a decision was made to...

All non-human great apes are endangered, and for these animals, captive individuals play an important role in the species’ conservation management plan. Therefore, information about their current enrichment activities is essential for maintaining a healthy...

Over evolutionary time, light from the sun, moon, and stars has provided organisms with reliable information about the passage of time; but modern artificial lighting has drastically altered these cues. Evidence is accumulating that exposure...

The domestic cat (Felis silvestris catus) originates from the solitary living African wildcat (Felis silvestris lybica). However, through domestication, the domestic cat has become more social towards conspecifics and group housing of cats is common...

The goal of the present study was to assess how cats react to tastes previously reported to be preferred or avoided relative to water. To this end, the facial and behavioral reactions of 13 cats...

The Principles and guidelines for the care and use of non-human primates for scientific purposes is a revision of NHMRC’s Policy on the care and use of non-human primates for scientific purposes 2003 (the Policy)...

Knowledge of the organization and dynamics of the relationships between animals and the environment and its resources is important to meet the needs of any species. We analyzed the effect the presence of a person...

Many studies have attempted to use music to influence the behavior of nonhuman animals; however, these studies have often led to conflicting outcomes. We have developed a theoretical framework that hypothesizes that in order for...

Every day, millions of domestic cats are held temporarily in captive environments, such as boarding catteries and rescue shelters. Being in confinement can potentially invoke high levels of stress for these animals. Therefore, there is...

Minimizing the number of animals in regulatory toxicity studies while achieving study objectives to support the development of future medicines contributes to good scientific and ethical practices. Recent advances in technology have enabled the development...

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...

Surveillance of cat shelters by official veterinarians in Austria is based on legal requirements and does not directly assess cat welfare. The aim of this study was to develop animal-based parameters that are feasible to...

Three decades ago, the Animal Welfare Act was amended to require researchers to provide environments that promoted the psychological, as well as the physical, wellbeing of nonhuman primates maintained for research purposes. We developed a...
