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 females were trained to present to us by positioning their hindquarters right up to the fence. We then desensitized them to a smooth plastic syringe casing being inserted into the vagina. This behavior would...

Access to enrichment items (e.g., corks, buttons, balls) reduced the incidence of cannibalism in young birds.

Cold-blood animals tend to have much greater problems adapting to changes in their species-typical environment than warm-blooded animals do.

Dust-bathing regulates the amount of feather lipids and maintains down structure in good conditions in laying hens. Poor feather condition negatively influences animal welfare. Hens need an opportunity to bathe in a dusty substrate.

The author succinctly summarizes the prevailing attitude of investigators toward their research subjects: The investigator, above all, wants to pursue his or her research activities, be they of basic science or clinical nature. The academic...

Tumor induction by 7,12-dimethylbenz[a]anthracene (DMBA) or inoculation with adenocarcinoma cells was studied in rats raised in groups (group G) or individually (group I) as well as in rats raised in groups and switched to individual...

Aberrant serum ticarcillin concentrations were measured when the animals were simply picked out, put on a laboratory bench, and wrapped in a towel to restrain them for blood collection. No aberration occurred in quasi trained...

The provision of enrichment object [tire hung from chains, pig-pacifier toy , teeter-totter ] reduced aggression among newly weaned pigs.

The aim of this study was to examine whether sheep can adapt to emotional stress evoked by individual isolation from the flock. The experiments were performed on 12 sheep divided into 2 groups; the control...

With increased area, head scratching, body shaking and feather raising were performed at a higher rate and cage pecking at a lower rate. .. Welfare implications are briefly discussed.

Single-caged rabbits were not able to hop in rabbit-typical fashion; they were less active but more restless [frequent activity changes] and showed more stereotypical gnawing of the wire cages than group-housed animals. It is evident...

Choice tests indicated that hens prefer large cages rather than small ones, and littered floors rather than wire floors. Hens placed only a low priority on having access to litter relative to increased cage size.

Habituation attenuates the fear normally associated with novel situations.

The urine-marking behaviour of free-living house mice,Mus domesticusRutty, was investigated in a poultry house where mice defended small territories and where evidence of previous marking behaviour was extensive. Thin smears of urine were found spread...

Six pairs of mares, each with established dominant-subordinate relationships, were allowed to compete for feed in a 112-cm trough following 24 h of deprivations. .. Differences in feeding times between dominant and subordinate mares were...

If mice were placed in a novel environment with metal foil or cardboard available, they chewed these materials. These animals had lower plasma corticosterone levels in novel cages than mice in the same environment without...

Pigs raised in pens with hanging rubber hose toys and weekly petting were less excitable compared to pigs raised with no extra environmental stimulation.
