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 latest edition of the seminal reference on the care and management of laboratory and research animals. The newly revised ninth edition of The UFAW Handbook on the Care and Management of Laboratory and Other...

This volume reviews the broad topic of welfare in nonhuman primates under human care. Chapters detail the history of primates in captivity, ethical and legal issues surrounding the use of nonhuman primates as entertainment or...

The objective of the study was to investigate the effects of housing (deep litter + concrete floor vs. deep litter + ground soil with the possibility to dig burrows), and genotype (Mecklenburg or Hyplus) on...

Climate change includes different dramatic events, and among them, heat stress exposition is the strongest phenomenon affecting the livestock sector. The effects of heat stress events on animal welfare are complex and the economic impacts...

Mixed species exhibits in zoos are used to create larger, more stimulating environments to support naturalistic interactions between species. In the wild, mixed species groups are observed as having lower rates of vigilance, presumably due...

The weaning of pigs in most commercial pork production systems is an abrupt event performed at a fairly young age, i.e., mostly between 2.5 and 5 weeks of age. This practice induces a stress response...

Although there exist several studies examining the housing needs of rabbits kept in laboratories and for meat, studies of the requirements of pet rabbits are few and focus entirely on single rabbits. Pet rabbits are...

Access to an outdoor run improves the housing conditions of fattening pigs by an enlarged space allowance, access to different climatic conditions and environmental stimulation. One central conflicting issue regarding outdoor runs is the emission...

In recent years, there has been much research into the individual effects of enclosure complexity and visitor presence on captive animal welfare. However, the inter-linkages between enclosure complexity and visitor presence and their combined influence...

There is an ethical responsibility to provide all animals living in human care with optimal and positive well-being. As animals living in zoos and aquariums frequently interact with their human caregivers as part of their...

The Greater Bermuda land snail Poecilozonites bermudensis was once thought to be extinct in the wild, however, recent captive population increases have allowed reintroductions to take place. Post-release monitoring of reintroduced individuals is a fundamental...

Conservation aquaculture offers important tools to secure sustainable animal supplies for human use. However, intensive aquaculture practices are increasingly raising concerns about the welfare conditions of farmed animals, which typically face high mortality rates due...

Containment cages are one of the main causes of chronic stress and reduced welfare during swine production as well as in hot environments. The objective of this study was to evaluate behavioral changes and physiological...

Animal welfare is important for the humane treatment of animals under our care. Zoos and rescue centres manage various charismatic animals, such as big cats, with limited resources. It is therefore essential for caretakers to...

A shelter is a good habitat for aquatic organisms, which could aid in avoiding cannibalism and facilitate predation. Chinese Mitten Crab (Eriocheir sinensis) is an important aquaculture species with troglodytism and nocturnal habit. To clarify...

Previously, we housed guinea pigs in pairs, where study design allowed, using RC2R cages (NKP-Isotec). Our change was to house guinea pigs in bigger groups with more space. This resulted in moving the guinea pigs...

Farrowing crates present a major animal welfare problem. This study investigated the effects of temporary confinement at farrowing on sow welfare and aimed to determine whether this type of system could improve sow welfare through...

This study aimed to determine the effect of three different farrowing huts on the behaviour of outdoor housed sows and piglets during summer in Eastern Canada, with a focus on thermoregulatory and crushing behaviours. Forty-two...

Naked mole rats (Heterocephalus glaber) are a unique rodent species originating in Africa and are increasingly being used in research. Their needs and characteristics differ from those of other rodents used in research. Unique housing...

Macduff Marine Aquarium is a native species aquarium situated on the Moray Firth coastline and houses the curled octopus, Eledone cirrhosa, for public display. Historically, the designated octopus display tank has been in-keeping with the...

Today's livestock agriculture faces major changes in domestic pig husbandry—besides animal health and productivity, aspects of animal welfare and animal-friendly husbandry systems for pigs increasingly gain attention. To get a basic and current overview of...

Since they arrived at CU Boulder, we have learned a lot about the voles from the laboratory, other institutions, and our trial-and-error. We hope this information can be helpful to any considering adding voles to...

Naked mole-rats (NMRs) have unique husbandry requirements that need to be considered when maintaining them in captivity. We have successfully maintained NMRs at the University of Illinois at Chicago for more than 20 years. This...

Naked Mole-rats have been studied in laboratories for decades due to their unique behavior and physiology. They are one of a few species of mammals that maintain a hive social structure, are highly resistant to...

Naked Mole-rats are relative newcomers in the research world. Due to the complexity of their natural subterranean tunneling system, it has been difficult to replicate in the laboratory environment. Housing standards often differ from the...
