Comparison of 2 gentling programs for laboratory rats: Effects on the behavior toward humans

Gentling can reduce the fear reactions of young laboratory rats toward people long term. We were able to show this outcome in a previous study that involved a successful but elaborate gentling program. In the study at hand, we investigated...

Behavioral observations in dogs in 4 research facilities: Do they use their enrichment?

European legislation recommends comfortable resting areas, toys, and chews in laboratory dogs' husbandry. However, there is no standard “enrichment” defined for laboratory dogs as yet. Different research facilities provide different housing conditions and forms of enrichment. To get an overview...

Influence of crate height on the welfare of broilers during transport

Poultry transport systems are currently under investigation with a particular focus on design and dimensions of commercially available transport crates. The height of the crates currently used is debated and considered by some parties to be insufficient to fulfill animal...

Shade as enrichment: Testing preferences for shelter in two model fish species

We compared preferences shown by zebrafish (Danio rerio) and three-spined stickleback (Gasterosteus aculeatus) for shelter provided by above-tank shade and artificial plants. Zebrafish showed no preference for either shelter, whereas sticklebacks showed a preference for both shelter types over open...

International survey on the use and welfare of zebrafish Danio rerio in research

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 from laboratories in 22 countries...

The effect of environmental colour on the growth, metabolism, physiology and skin pigmentation of the carnivorous freshwater catfish Lophiosilurus alexandri

The growth, physiology and skin pigmentation of pacamã Lophiosilurus alexandri juveniles were evaluated in an experiment using different tank colours (white, yellow, green, blue, brown and black) over an 80-day period. The tank colours did not cause significant differences to...

A minimally invasive technique to assess several life-history characteristics of the endangered great hammerhead shark Sphyrna mokarran

A dorsal-fin photo-identification technique paired with a non-invasive parallel laser photogrammetry technique was used to non-invasively identify individual Sphyrna mokarran over time. Based on the data collected over a duration of 59 days, 16 different S. mokarran (mean ± s.d....
