Environmental Enrichment

Includes structural, behavioral, food, and auditory enrichment.

Bennett, A. J., Corcoran, C. A., Hardy, V. A. et al. 2010. Multidimensional cost-benefit analysis to guide evidence-based environmental enrichment: Providing bedding and foraging substrate to pen-housed monkeys. JAALAS 49(5), 571-577.

Refinement of animal care and housing is an important shared goal - and challenge - of the team of research, veterinary, and animal care personnel charged with ensuring the wellbeing of laboratory animals. This study...

Camacho, J. N., Britz, W., Perlman, J. E. et al. 2010. Interactive enrichment housing for nonhuman primates. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 666 (Abstract #PS46).

Environmental enrichment is commonly provided to diversify an animal’s surroundings while maintained in captivity. Traditional enrichment approaches may not provide sufficient environmental complexity and cognitive stimulation. Consequently, housing was designed for laboratory nonhuman primates to...

De Villiers, C., Seal, J. V. 2010. Solid floors versus wire floor housing for rats revisited: Influence of age and the presence of test boxes. Animal Technology and Welfare 9, 31-36.

Data did not reveal a clear preference for solid floors. Juveniles were found most often on wire floors while among adults, a preference for solid floors was apparent only in females, and only when a...

Dixon, L. M., Duncan, I. J. H., Mason, G. J. 2010. The effects of four types of enrichment on feather-pecking behaviour in laying hens housed in barren environments. Animal Welfare 19(4), 429-435.

Severe feather pecking, a potentially stereotypic behaviour in chickens (Gallus gallus), can be reduced by providing enrichment. However, there is little comparative information available on the effectiveness of different types of enrichment. Providing forages to...

Edgar, J. L., Seaman, S. C. 2010. The effect of mirrors on the behaviour of singly housed male and female laboratory rabbits. Animal Welfare 19(4), 461-471.

It is widely recognised that single housing is detrimental to the welfare of social species. However, some experimental procedures dictate that laboratory animals are housed individually. There is evidence to suggest that, by mimicking social...

Ellis, L. H., Wells, D. L. 2010. The influence of olfactory stimulation on the behaviour of cats housed in a rescue shelter. Applied Animal Behaviour Science 123(1-2), 56-62.

A wide variety of feline species have been shown to gain welfare benefits from the introduction of olfactory stimuli to the captive environment. The effect of this stimulation on the domestic cat, however, has been...

Farmer, A. M. 2010. Housing, care and accommodation: An inspector's observation on how these can affect rodent welfare. Animal Technology and Welfare 9, 94-96.

In my view it is vitally important that scientists and management pay attention to what animal technologists and care staff have to say about the care and requirements of experimental animals.
