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. 

There are a multitude of health monitoring techniques/ methods available. It can be difficult to know which of these to use and when to use them. This is an attempt to simplify, maximise the efficacy...

Background: Farm animals (FAs) are frequently used in biomedical research. Recommendations for the purchase, housing and health monitoring of these animals (sheep, goats, cattle and pigs) are still missing, and many institutes have developed their...

The advanced development of sensor technologies has led to the emergence of fish biosensors that are currently used for research and commercial purposes. AEFishBIT is a miniaturized biosensor attached to fish operculum that measures physical...

One important type of animal welfare concern is “natural living” (i.e., that animals are able to express natural behaviours that are important to them, and to engage with aspects of the natural world that they...

The concept of animal welfare (AW) has many meanings. Traditionally, AW has been considered as freedom from disease and suffering. Nowadays, growing attention goes to the concept of “positive animal welfare” (PAW), which can be...

We used an operant conditioning paradigm to test the motivation of non-pregnant dairy heifers to access shade during the summer and autumn months (January to June) in southern Brazil. Dairy heifers (n = 18) were...

The white-naped mangabey is an endangered and rare zoo species, yet little is known concerning their welfare in captivity. The assessment of welfare should incorporate a net balance of negative and positive welfare behavioural indicators...

Providing a natural diet is a key component to improving animal welfare and potentially reducing stereotypic behaviours in captivity. Wild slow lorises (Nycticebus spp.) are threatened by illegal wildlife trade, and in Thailand, confiscations from...

Small, tropical fish are popular companion animals and constitute a major proportion of the vertebrates used in scientific research, but little is known about how they are affected by routine husbandry practices. Manual tank cleanings...

Gentle human-animal interactions can induce positive emotions in cattle and enhance their welfare. We investigated whether a change in the animals’ perceived control over the situation influences their perception of the interactions. We compared the...

There is an interest in alternative rearing systems that allow for prolonged cow-calf contact (CCC). Yet, a better understanding of cows’ affiliative behaviour in those systems is needed. We evaluated the effect of type of...

In confrontations, many behaviors are based on visual information. To establish the importance of visual signals in the aggression of cichlid fish, we observed the behavior of groups in three juveniles of Nile tilapia (six...

In 2017 Bristol Zoological Gardens received two Goodfellow tree kangaroos. As this was a new marsupial species for the collection, keepers attended the European Symposium on tree kangaroos to better improve our husbandry, knowledge and...

Background: The nature and depth of bedding material have an important influence on cow lying behaviour and comfort. Increasing use of recycled manure solids (RMS) as bedding led to an investigation of the influence of...

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...

Positive stockperson attitudes to his or her animals is associated with a positive behavioural response in the animals and in other indicators assumed to reflect a high level of welfare as well as increased productivity...

Dairy calves must be fed appropriately to meet their nutritional needs, supporting optimal growth and development to achieve the recommended target age at first calving (AFC) of 24 months. Traditional restricted milk feeding practices suppress...

As the reliance upon automated systems in the livestock industry increases, technologies need to be developed which can be incorporated into these systems to monitor animal health and welfare. Infrared thermography (IRT) is one such...

The bedding materials used in dairy cow housing systems are extremely important for animal welfare and performance. A wide range of materials can be used as bedding for dairy cattle, but their physical properties must...

Gentle animal–human interactions, such as stroking, can promote positive emotions and thus welfare in cattle. While previous studies showed that stroking at the ventral neck elicited the most positive reactions in cows, intra-specific allogrooming in...

Mechanical brushes allow cows to groom. Mange is common in indoor-housed cattle, and this affliction may affect cow motivation to use a mechanical brush. The aim of this study was to assess changes in dairy...

Previous studies have demonstrated that dairy cattle prefer pasture over indoor conditions especially at nighttime, which suggests they perceive pasture as an attractive place to rest. Indeed, cows avoid and spend less time lying on...

A widespread management practice in commercial dairy farms is to stop milk production artificially commonly 2 months before expected calving, in a process termed drying-off. Dry-off management normally encompasses dietary changes as well as abrupt...

The aim of this study was to determine the effects of two housing systems (thermal plastic greenhouse roofs—PGR—vs. without roof—PWR) on health, welfare, and finishing performance of zebu steers in cold arid environments. A total...

Respirometry has become the standard method for measuring the metabolic rate of fishes. Traditionally, respirometry has required the fish to be kept in captivity and tested under controlled conditions; however, many species do not readily...
