The ‘Cage Climber’ – A new enrichment for use in large-dimensioned mouse facilities

Environmental Enrichment has been shown in experimental contexts to have clear and often beneficial effects on animal physiology and behavior. Housing prior to experiments can represent a large proportion of an animal’s living conditions, and improving housing conditions can be...

The effect of group size, age and handling frequency on inter-male aggression in CD 1 mice

Aggression in male mice often leads to injury and death, making social housing difficult. We tested whether (1) small group size, (2) early age of allocation to a group decreases aggression and 3) manipulation increases aggression in male mice. A...

The effect of housing environment on bone healing in a critical radius defect in New Zealand white rabbits

In animal studies on bone healing, the effect of housing space and physical activity are seldom taken into account. Bone formation was evaluated in New Zealand White rabbits (mean ± SEM BW: 3.9 ± 0.11 kg) with a critical bone...

The effect of qualitative feed restriction in broiler breeder pullets on fear and motivation to explore

Restrictively fed broiler breeders are known to have increased motivation to explore and reduced fearfulness because hunger increases the motivation to search for and to acquire food, forcing the birds to face and engage with aversive stimuli that they would...

The effect of shelter on oxidative stress and aggressive behavior in crested newt larvae (Triturus spp.)

Shelters are important for animal survival. Provision of adequate hiding places allow animals to express their natural sheltering behavior and it can have different positive effects on cortisol levels, physiological processes and mental performance. Although the absence of a refuge...

The effect of triploidy on the performance, gut microbiome and behaviour of juvenile Atlantic salmon (Salmo salar) raised at low temperature

Triploid Atlantic salmon (Salmo salar) aquaculture has been extensively considered for many years, but its development has so far remained very limited. This is mostly due to poorer farming performances of triploid fish (3 N) in comparison with their diploid...

The effects of different feeding routines on welfare in laboratory mice

The accepted norm in most laboratories around the globe is feeding laboratory mice an ad libitum diet, although several health impairments are well-established. In contrast, reducing the animals' body weight by feeding them less food once per day (referred to...

The effects of the frequency and method of gentling on the behavior of cats in shelters

Gentling of cats in a shelter has been shown to increase contented behaviors and reduce anxiety, but it is not clear how gentling should be provided. Two experiments were conducted in cats confined to cages, each having a central room...
