Environmental Enrichment

Includes structural, behavioral, food, and auditory enrichment.

Kiddie, J., Bodymore, A., Dittrich, A. 2017. Environmental enrichment in kennelled pit bull terriers (Canis lupus familiaris). Animals 7(4), 27.

Although social enrichment can be considered beneficial in helping dogs cope with the kennel environment, when taking individual needs into account, it places a large demand on the carers and may not be appropriate in...

Vermeer, H., Dirx-Kuijken, N., Bracke, M. 2017. Exploration feeding and higher space allocation improve welfare of growing-finishing pigs. Animals 7(5), 36.

Lack of environmental enrichment and high stocking densities in growing-finishing pigs can lead to adverse social behaviors directed to pen mates, resulting in skin lesions, lameness, and tail biting. The objective of the study was...

Pinelli, C., Leri, F., Turner, P. 2017. Long term physiologic and behavioural effects of housing density and environmental resource provision for adult male and female Sprague Dawley rats. Animals 7(6), 44.

There is considerable interest in refining laboratory rodent environments to promote animal well-being, as well as research reproducibility. Few studies have evaluated the long term impact of enhancing rodent environments with resources and additional cagemates...

Zobel, G., Neave, H., Henderson, H. et al. 2017. Calves use an automated brush and a hanging rope when pair-housed. Animals 7(11), 84.

Calf housing often only meets the basic needs of calves, but there is a growing interest in providing enrichments. This study described the behaviour of calves when they were given the opportunity to interact with...

Winfield, J., Macnamara, G., Macnamara, B. et al. 2017. Environmental enrichment for sucker and weaner pigs: The effect of enrichment block shape on the behavioural interaction by pigs with the blocks. Animals 7(12), 91.

This experiment tested the effect of enrichment-block shape on oro-nasal contact by young pigs, and possible habituation to the blocks. Nineteen litters (197 piglets) were randomly allocated to one of three block-shape treatments: Cube, Brick...

Ralph, C., Hebart, M., Cronin, G. 2018. Enrichment in the sucker and weaner phase altered the performance of pigs in three behavioural tests. Animals 8(5), 74.

We tested the hypothesis that provision of enrichment in the form of enrichment blocks during the sucker and weaner phases would affect the behaviour of pigs. We measured the performance of pigs in an open...

André, V., Gau, C., Scheideler, A. et al. 2018. Laboratory mouse housing conditions can be improved using common environmental enrichment without compromising data. PLOS Biology 16(4), e2005019.

Animal welfare requires the adequate housing of animals to ensure health and well-being. The application of environmental enrichment is a way to improve the well-being of laboratory animals. However, it is important to know whether...

Gaskill, B. N., Garner, J. P. 2017. Stressed out: providing laboratory animals with behavioral control to reduce the physiological effects of stress. Lab Animal 46(4), 1

Laboratory animals experience a large amount of environmental stress. An animal’s environment can include both physiological and social stressors that may require an animal to adapt to maintain allostatic balance. For example, thermal stress can...

Soriano, A. I., Vinyoles, D., Maté, C. 2016. Long-term macroevaluation of environmental enrichment in three brown bears (Ursus arctos) at Barcelona Zoo. Journal of Applied Animal Welfare Science 19(1), 49-61.

The evaluation of enrichment programs is important to determine their effect on nonhuman animal welfare. The daily activity pattern and use of space of 3 brown bears (Ursus arctos) were used for long-term macroevaluation of...
