Wistar rats do not show preference for either of two commonly used nutritionally sound food rewards in a T-maze

Food rewards are commonly used as positive reinforcement in rodent behavioral experiments. Bioserv dustless precision pellets and Noyes formula P precision pellets are both used for this purpose in behavioral experiments in multiple laboratories, as they are nutritionally consistent with...

Classical music reduces acute stress of domestic horses

Domestic horses are regularly subjected to stressful situations due to management practices, such as social isolation, transport and farriery or, in general due to exposure to new/sudden stimuli. These situations may eventually be harmful to the horses' welfare, possibly altering...

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...

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...
