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. 

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...

Continuous tethered infusions in any animal model pose a unique set of problems. These problems are amplified when nonhuman primates are the model. A high tolerance to the tether system by an animal model is...

Rabbits are known to be finicky about food and will reject it based upon several factors: odor, texture, form, or method of presentation. It can be an even greater challenge to get rabbits to eat...

In the zoo environment, anthropogenic noise is common as sound levels fluctuate due to visitors, construction, habitat design, and special events. In this study, changes in the mood of three species of zoo-housed primates in...

Macaques are often motivated to perform in neuroscientific experiments by implementing fluid restriction protocols. Daily access to water is controlled and the monkeys are rewarded with droplets of fluid for performing correct trials in the...

Fin clipping of live fish under anesthesia is widely used to collect samples for DNA extraction. An alternative, potentially less invasive, approach involves obtaining samples by swabbing the skin of nonanesthetized fish. However, this method...

Endotracheal intubation of laboratory animals is a common procedure shared by several research fields for different purposes, such as mechanical ventilation of anaesthetized animals, instillation of cytotoxic nanoparticles, infectious agents or tumour cells for induction...

The zebrafish has become a valuable research model within the laboratory. Currently the proven method of genotyping involves taking a tail fin clip from the fish to gain the sample. This involves surgically removing a...

Fin clipping of live fish under anaesthesia is widely used to collect tissues samples for DNA extraction. However, this technique raises a number of ethical concerns, since the use of anaesthetic and/or physical fin damage...

There has been increased recognition of the 3Rs in laboratory animal management over the last decade, including improvements in animal handling and housing. For example, positive reinforcement is now more widely used to encourage primates...

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...

A survey was conducted regarding zebrafish Danio rerio use for scientific research with a focus on: anaesthesia and euthanasia; housing and husbandry; breeding and production; refinement opportunities. A total of 98 survey responses were received...

Training techniques that prepare laboratory animals to participate in testing via cooperation are useful tools that have the potential to benefit animal wellbeing. Understanding how animals systematically vary in their cooperative training trajectories will help...

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...

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...

Despite the growing interest in research on the interaction between humans and dogs, only a very few research projects focus on the routines between dogs and their owners. In this study, we investigated one such...

This paper describes the use of a validated quality of life assessment tool (described elsewhere) to identify environmental and management factors that may affect quality of life in dogs kennelled in rehoming centres. Dogs were...

The common marmoset (Callithrix jacchus) is a New World primate that is a useful model for medical studies. In this study, we report a convenient, reliable, and noninvasive procedure to genotype a living common marmoset...

When training animals, time is sometimes a limiting factor hampering the use of positive reinforcement training (PRT) exclusively. The aim of this study was to evaluate the effects of a combination of negative and positive...

In modern zoos, training should be an integral component of the animal care and management. The benefits of training include the opportunity for positive interactions with caretakers. This study was carried out with a group...

Positive reinforcement training can be used in many ways to enhance the welfare of captive primates. Training for biologic sample collection is one application of positive reinforcement training. In this study, 35 adult female chimpanzees...

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...

The effect of animal-assisted activities (AAA) on the animal participants has been minimally investigated, and the welfare of these animals has been questioned. To enhance our understanding of these animals’ welfare, we measured cortisol collected...

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...
