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. 

Various pharmaceutical products have been derived from horse blood and urine for over a century. Production of biologics and therapeutics from these samples is a niche industry and often occurs in regions with little regulation...

Every animal species has particular environmental requirements that are essential for its welfare, and when these so-called “basic needs” are not fulfilled, the animals suffer. The basic needs of horses have been claimed to be...

The satisfaction of leisure horses’ behavioral needs has begun to be considered a priority, linked to the awareness that horses kept in single boxes may be deprived of social contact and the possibility to perform...

Medetomidine partial intravenous anaesthesia (PIVA) has not been compared to xylazine PIVA regarding quality of recovery. This clinical retrospective study compared recoveries following isoflurane anaesthesia balanced with medetomidine or xylazine. The following standard protocol was...

Sleep is crucial to horses’ wellbeing, and their lying time can vary according to such factors as climate, exercise, bedding, and housing. This study aimed to analyze behavior and time spent in lying halls of...

Despite their diffusion worldwide, many aspects of donkeys’ behaviour and cognitive abilities are still poorly understood and overshadowed by a corpus of commonplaces. The possibility of better knowing this species is of key relevance for...

Background: Isoflurane is the only volatile anaesthetic agent licensed for equine use in the United Kingdom, but sevoflurane is also commonly used. The two agents have rarely been compared for use in clinical elective surgery...

This species first arrived at Chester Zoo in June 2014 when a colony of 27 animals was imported from Dresden Zoo, Germany. As with any new species our journey with naked mole rats has not...

In the last decades, an engineering process has deeply transformed livestock houses by introducing fine-tuned climate control systems to guarantee adequate indoor climate conditions needed to express the maximum genetic potential of animals and to...

During the evolution of the horse, an extended period of feed intake, spread over the entire 24-h period, determined the horses’ behaviour and physiology. Horses will not interrupt their feed intake for more than 4...

Exposure to environmental factors such as high temperatures and solar radiation levels present a welfare concern for many domestic equids. Understanding how these factors influence the shelter use of healthy equids can inform welfare guidelines...

Given the paucity of published data on the effects of artificial weaning on mares, the aim of the present study was to investigate the behavioral and hormonal effects of two different weaning methods in trotter...

Gastrointestinal stasis is a common perianaesthetic complication in rabbits. The objective of this study was to assess the impact on gastrointestinal transit time of ketamine–midazolam (KMZ) versus ketamine–medetomidine (later antagonised by atipamezole) (KMT-A) in rabbits...

Few data are published about different ferret husbandry practices in terms of housing, enrichment, feeding, social management, and the health status of ferrets. However, these factors are crucial for animal welfare and influence animal behavior...

Plasma lipid and glucose levels are important parameters for evaluating the onset and development of metabolic and cardiovascular diseases. In clinical and experimental studies of humans or mice, fasting is often required before testing plasma...

Capybaras, also known as “water pigs,” are the world’s largest rodent. Although these animals are closely related to guinea pigs, with a shoulder height of approximately 2 ft, coarse brown fur, and partially webbed feet...

Relocating laboratory animal research from one animal facility room to another in advance of major renovations can be a daunting task for scientists and animal care personnel alike. This is especially so regarding controlled lighting...

The naked mole rat (Heterocephalus glaber) is a rodent that has gained importance as a biomedical research model for various conditions including hypoxic brain injury, cancer and nociception. It is captured from the wild and...

Triploid Atlantic salmon (Salmo salar) aquaculture has been extensively considered for many years, but its development has so far remained very limited. This is mostly due to poorer farming performances of triploid fish (3 N)...

In semi-natural mixed-sex groups, rabbits (Oryctolagus cuniculus) organize their social life by forming a hierarchy, which is characterized by linearity and stability. Compared to the natural environment, many factors are different in contemporary breeding systems...

Horse confinement is a common practice worldwide. However, preventing horses from grazing and denying them social interaction can compromise their welfare and lead to undesirable consequences. Considering the hypothesis that increasing the forage consumption time...

Grazing muzzles are used on obese-prone equids to limit intake of pasture while grazing. However, the length of time grazing muzzles must be worn to prevent weight gain and whether they impede normal grazing behavior...

Grazing muzzles are a popular and effective management tool used to help prevent weight gain in obese-prone equids. Concerns have been raised over their possible negative impact on horse well-being as muzzles may interfere with...

This work provides an overview of the role of chemical communication in horse behavior and addresses the potential usefulness of this knowledge for management practices and animal welfare. First, we present an outline of the...

This review focuses on associations of cortisol and the hormone ghrelin on abnormal oral behaviors, predominantly stereotypic behavior, in horses. Abnormal oral behaviors are prevalent in the stabled horse population. Feeding practice and satiety seem...
