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. 

This work aimed at evaluating the effects of housing system, pen floor type, and lactation management on rabbit doe and kit performance throughout a reproductive cycle, including categorization of aggressiveness and injuries. Forty multiparous pregnant...

The effect of extensive human presence and regular gentle handling performed at an early age (0–3 months old) on stress responses and reactivity of juvenile ostriches towards humans was investigated. A total of 416 ostrich...

Reinforcer effectiveness refers to the reinforcer’s ability to control the subject’s target behaviour and is therefore critical to training success. Yet animals’ preferences, and the effectiveness of different rewards to function as reinforcers, are often...

Raccoon dog (Nyctereutes procyonoides ussuriensis) is the only canid species using facultative passive wintering strategy. The aim of the present study is to document the behaviour and welfare of the farmed variant of the species...

Though European rabbits are a social species, socially housing them can be challenging. Therefore, there must be a thorough understanding of behaviors and social structures of pair-housed laboratory rabbits. Here we present a protocol to...

Human physical contact is known to be effective in decreasing dogs' level of stress, assessed through endocrine, physiological, and behavioral parameters. Gentle touching has been found to be beneficial for dogs while experiencing or after...

Guinea pigs are included in various animal-assisted interventions (AAIs), but no research has been published to date on behavioral changes in guinea pigs interacting with humans. The goal of this study was to evaluate the...

Rabbits are usually singly housed in laboratories, but a new emphasis on providing social housing for social species has prompted exploration of alternative housing for this species. However, a paucity of literature on the social...

Dogs are individually housed when collecting data for ECG studies to avoid any cross talk between transmitted signals (generally for a 24 hour recording period). Each implant is set at a certain frequency which transmits...

The 8th Edition of the Guide for the Care and Use of Laboratory Animals clarified its language regarding housing social species, specifying that, “Single housing of social species should be the exception…”. This is a...

Recent studies suggest that cognitive bias could constitute a novel and valid measure of animal welfare. Although interest for a link between personality and cognition is growing, no study to date investigated whether a cognitive...

The methods by which dogs are trained vary between methods involving mainly negative reinforcement and positive punishment (aversive-based methods) and methods based essentially in positive reinforcement and negative punishment (reward-based methods). However, the use of...

The aim of this work was to study how the group size and the number of doorways in a pen may influence the aggressive interactions throughout the reproductive cycle among does kept in a part-time...

Social learning is the capacity of animals to acquire adaptive information from others. In the case of fear responses, animals can learn fearful or non-fearful responses by observing the behavior of conspecifics. Tonic immobility (TI)...

The purpose of this pilot study was to determine if Rhea americana chicks could be trained to walk voluntarily across a scale to be weighed. If the chicks were trainable, the following questions would be...

Numerous studies conducted to assess welfare of domestic dogs housed in kennel facilities have reported that these dogs experience suboptimal living conditions. One important goal of improving welfare of kennelled dogs is to reduce their...

Social pain is the negative affect signaling threat or harm to social relationships. Loneliness is perceived social isolation and can be found across phylogeny. Evidence from diverse fields demonstrates an overlap of social and physical...

This poster is based on welfare improvements gained from group housing rabbits in floor pens in the new Antibody Production Facility with a focus on development, behaviours and environmental enrichment in both male and female...

Training is recognised as important for laboratory animals, both to improve welfare and increase the efficiency of conducting husbandry and regulated procedures. Despite the acknowledged need for such training in the laboratory-housed dog and the...

In the attempt to verify clicker training efficacy in shaping dogs’ novel behaviours, we studied 51 domestic dogs. Learning was evaluated in three different conditions: when the primary reinforcer (food) was presented in association with...

Group housing is becoming the standard for many farm animal species, as it is seen as a more welfare friendly way of keeping gregarious animals. Aggression between female breeding rabbits currently obstructs the implementation of...

The objective of the study was to investigate if environmental enrichment and the composition of the social group would affect the behavior and relative brain weight of growing rabbits. Rabbits (72 males and 72 females)...

Our goal was to improve dog socialization by increasing novel human interactions, while also providing non-animal care staff opportunity to interact with the dogs. Our volunteer dog socialization program was developed to explore the possibility...

Introduction: The Safety Pharmacology Society (SPS) and National Centre for the Replacement, Refinement & Reduction of Animals in Research (NC3Rs) conducted a survey and workshop in 2015 to define current industry practices relating to housing...

Introduction: There is a growing weight of evidence to suggest that myocardial contractility is an important parameter to assess as part of IND enabling studies in addition to standard assessments as per the ICH S7A...
