The effect of experience of ramps at rear on the subsequent ability of layer pullets to negotiate a ramp transition

In commercial situations, laying hens must negotiate levels to reach resources such as food, water and litter. Providing ramps in aviary systems reduces collisions and resultant keel bone fractures in adults. We investigated whether providing ramps during rear improved the...

Dairy goats use outdoor runs of high quality more regardless of the quality of indoor housing

For dairy goats in loose housing, access to an outdoor run has potential welfare benefits as it provides additional space, enables spatial separation and may offer items representing behavioural enrichment for the goats (e.g. brush, climbing possibilities). However, these benefits...

Colour polymorphic Gouldian finches avoid complex backgrounds but prefer simple camouflage colours over white backgrounds

Many animals blend in well with their environment known as camouflage which is a successful predator avoidance strategy. However, captive environments often do not allow for camouflage and may result in stress and reduced welfare. We investigated whether colour polymorphic...

Using radio-frequency identification technology to measure synchronised ranging of free-range laying hens

Free-range laying hen systems provide individuals a choice between indoor and outdoor areas where range use may be socially influenced. This study used radio-frequency identification technology to track the ranging of individually-tagged hens housed in six experimental free-range pens from...

Lying postures of dairy cows in cubicles and on pasture

Cows housed indoors with cubicles are probably more restricted in their choice of lying posture and orientation compared with cows housed on pasture. We therefore compared lying postures on pasture in Uruguay and the Netherlands with lying postures in cubicles...

Standard laboratory housing for mice restricts their ability to segregate space into clean and dirty areas

Laboratory mice (Mus musculus) are typically housed in simple cages consisting of one open space. These standard cages may thwart mouse ability to segregate resting areas from areas where they eliminate, a behaviour that is prevalent across the animal kingdom....

A comparison of activity patterns of captive chimpanzees (Pan troglodytes) housed in primadomes™ or corrals

Primadomes™ and corrals, two types of housing options available to captive chimpanzees, differ in several physical features, including closed (primadomes™) or open (corrals) tops, mesh (primadomes™) or concrete (corrals) walls, and available space per animal (142 ft2/individual in primadomes™; 516...

Larger cages with housing unit environment enrichment improve the welfare of marmosets

The provision of adequate space for laboratory animals is essential not only for good welfare but accurate studies. For example, housing conditions for primates used in biomedical research may negatively affect welfare and thus the reliability of findings. In common...

An assessment of porches as enrichment for singly housed cynomolgus macaques (Macaca fascicularis)

Effective environmental enrichment encourages usage, promotes species‐typical behaviors, and/or decreases abnormal behaviors. Porches are small cages that attach to the primary cage of an animal to provide additional space and a better view of the surroundings. This study aimed to...

Enhanced physical environment in single-housed macaques: A long-term usage profile of cage extensions

Social housing is always preferred in the research environment; however, single housing is sometimes necessitated by scientific objectives or social incompatibility. In these cases, other environmental enhancements are developed to provide indirect social interactions. We developed a novel cage extension...
