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. 

Cows on two separate farms were submitted to a 6 d preference test, repeated four times, consisting of three 2 d phases (3 h d−1 phase−1): forced-indoor, forced-outdoor, and free-choice. A majority of cows on...

Undesirable behavior (e.g. biting, kicking and aggression) during handling is a growing concern in the equine industry, and is likely to compromise horse-human relationships. The present study, carried out over 3 months, investigated the expression...

In order to give individually housed stallions the opportunity to have more social interactions, the Swiss national stud farm investigated a separation wall called ‘social box’. Sixteen adult Franches-Montagnes breeding stallions were housed for 3...

Laboratory dogs should be sociable with humans and react in a relaxed way when confronted with new stimuli and situations. This is of particular advantage when dogs are used in animal experiments and for the...

In order to provide research dogs enrichment at our facility, veterinary staff suggested adapting the adjacent space to our dog housing buildings to allow for more species-specific behavior by creating an exercise area that both...

The separate influences of spatial density and housing quality on the behavior of captive animals are difficult to measure because the two factors are often intrinsically linked. Here, we recorded affiliative and agonistic behavior in...

Guinea pig pups produce typical distress whistles when isolated. Whistles’ frequency is decreased or abolished when they contact with the mother and, to a lesser degree, a sibling or even an unfamiliar female, is regained...

The goal of this study was to evaluate the effect of changing to IVC housing on guinea pigs by recording several physiologic parameters in guinea pigs housed sequentially in open-top cages (OTC) and IVC. To...

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...

Introduction: The dog is a frequently-used, non-rodent species in the safety assessment of new chemical entities. We have a scientific and ethical obligation to ensure that the best quality of data is achieved from their...

Housing laboratory primates in large pens can improve welfare by providing ample opportunity to express normal social and locomotor behaviors. This type of housing, however, can present great challenges in terms of manipulating animals for...

For animals in confinement housing the housing structure has tremendous potential to impact well being. Dogs in animal shelters are often housed in one of two types of confinement housing – single kennels and rooms...

The pole-and-collar method is one of several techniques that enable the safe transfer of a nonhuman primate from its home environment into a restraint chair without the need for sedation. It has been used within...

The goal of this project was to evaluate the efficacy of a porch in decreasing feces painting in captive rhesus macaques. The porch is a small extension that is hung on the outside of a...

The aim of this study was to assess the effects of space allowance (4.5 m(2)/head vs. 9 m(2)/head) on the behaviour of shelter dogs (Canis familiaris) at different times of the day (from 10:30 to...

Visual barriers have been shown to be valuable environmental components of nonhuman primate housing to break visual contact between conspecifics as well as between primates and their human keepers. The effect of visual barriers can...

Keeping shelter dogs in groups provides them with a more socially and physically enriched environment, but eventually it may cause them stress. Understanding dogs' communication could help shelter staff recognize and prevent undesirable communicative patterns...

The purpose of this study was to evaluate the influence of housing conditions on daily rhythm of total locomotor activity in dogs. Seven clinically healthy dogs (Canis familiaris) were used and divided into two groups...

Cognitive abilities likely evolved in response to specific environmental and social challenges and are therefore expected to be specialized for the life history of each species. Specialized cognitive abilities may be most readily engaged under...

This is the third volume of discussions that took place on the Laboratory Animal Refinement & Enrichment Forum (LAREF). This forum is dedicated to the exchange of personal experiences of refining the conditions under which...

Captive rhesus macaques sometimes exhibit undesirable abnormal behaviors, such as motor stereotypic behavior (MSB) and self-abuse. Many risk factors for these behaviors have been identified but the list is far from comprehensive, and large individual...

The overall benefits of an enrichment and exercise program for research canines has been well documented and is a required element, by the United States Department of Agriculture (USDA), of any institution’s Animal Care and...

Clinical Laboratory Animal Medicine: An Introduction, Fourth Edition offers a user-friendly guide to the unique anatomy and physiology, care, common diseases, and treatment of small mammals and nonhuman primates. Carefully designed for ease of use...

Traditional procedures for training nonhuman primates to be restrained in chairs typically involve very little use of positive reinforcement. In this talk, we detail a refined chair training procedure which uses a mix of positive...

Since there is evidence that the bottom cages can impact research, this should be a good reason to eliminate the two-tier system with its species-inappropriate bottom-tier cages.
