Computer-assisted enrichment for zoo-housed orangutans ( Pongo pygmaeus )
Contributor(s):: Tarou, L. R., Kuhar, C. W., Adcock, D., Bloomsmith, M. A., Maple, T. L.
The study of environmental enrichment has identified a variety of effective forms of enrichment, but there are widespread problems associated with their use. Few forms of enrichment are cognitively challenging, and even the most effective often result in rapid habituation. This study examined the...
Consequences of enhancing environmental complexity for laboratory rodents - a review with emphasis on the rat
Contributor(s):: Sorensen, D. B., Ottesen, J. L., Hansen, A. K.
Enhancing the complexity of the environments of captive animals is often referred to as environmental enrichment, and aims to have positive effects on the animals' well-being. Such enrichments may have consequences both for so-called 'normal' behaviour and for the pathophysiology of the animals...

Control, choice, and assessments of the value of behavioral management to nonhuman primates in captivity
Contributor(s):: Schapiro, S. J., Lambeth, S. P.
Many people have devoted considerable effort to enhancing the environments of nonhuman primates in captivity. There is substantial motivation to develop experimental, analytical, and interpretational frameworks to enable objective measurements of the value of environmental enrichment/behavioral...
Coping personality type and environmental enrichment affect aggression at weaning in pigs
Contributor(s):: Melotti, Luca, Oostindjer, Marije, Bolhuis, J. Elizabeth, Held, Suzanne, Mendl, Michael
This study investigated the effects of different environmental treatments and personality types on aggression at mixing of newly weaned domestic piglets. From birth to weaning, 16 litters were housed with their dams in either barren (B) or larger, substrate-enriched (E) environments. At 15 days...
Current status and future directions of applied behavioral research for animal welfare and conservation.
| Contributor(s):: Swaisgood, R. R.
The papers that follow in this special issue reflect the state of knowledge and theory in the fields of animal welfare and conservation behavior. A particular focus is placed on how enrichment can be used judiciously to improve welfare and to prepare captive animals for release back to the wild....
Cuttlefish in captivity: an investigation into housing and husbandry for improving welfare
| Contributor(s):: Tonkins, B. M., Tyers, A. M., Cooke, G. M.
The European cuttlefish ( Sepia officinalis) is often kept in public aquaria, is becoming more common in aquaculture, and is also the most frequently used cephalopod in European research. Since 1st January 2013, all cephalopods ( Mollusca) have been protected under UK/EU law (A(SP)A 1986,...
Degree of synchrony based on individual observations underlines the importance of concurrent access to enrichment materials in finishing pigs
| Contributor(s):: Zwicker, B., Weber, R., Wechsler, B., Gygax, L.
Pigs are sociable animals with a strong motivation to explore and forage, and it has been stated that they have a strong motivation to do so synchronously. We examined the synchrony of exploration in groups of finishing pigs when enrichment materials were offered. We used a novel measure of...
Demand for swimming water and running wheel with 1 min of access per reward
| Contributor(s):: Hansen, S. W., Jensen, M. B.
The purpose of the three experiments presented here was to quantify the priorities of mink for 1 min of access to swimming water and a running wheel, respectively, by demand functions. Furthermore, the results were compared to the results of previous experiments in which mink were tested with a...
Deprivation and Enrichment in Laboratory Animal Environments

Destructible Toys as Enrichment for Captive Chimpanzees
| Contributor(s):: Brent, Linda, Stone, Adam
The use of destructible objects or toys as enrichment for nonhuman primates has had promising results in terms of increased use and positive behavioral effect. The purpose of this project was to determine the use and durability of a number of inexpensive, destructible toys provided one at a time...
Determining the effects of duration and recency of exposure to environmental enrichment
| Contributor(s):: Ahlbeck Bergendahl, Ida, Salvanes, Anne Gro V., Braithwaite, Victoria A.
Experience can help animals adapt their behaviour to fit the environment or conditions that they find themselves in. Understanding how and when experience affects behaviour is important for the animals we rear in captivity. This is particularly true when we rear animals with the intent of...
Development and Validation of Broiler Welfare Assessment Methods for Research and On-farm Audits
| Contributor(s):: Meyer, Meaghan M., Johnson, Anna K., Bobeck, Elizabeth A.
Required auditing of on-farm broiler welfare in the United States has increased; however, a lack of validated tools exists for assessment of enrichment. National Chicken Council (NCC) guidelines were used on a subset of 300 Ross 308 broilers out of 1200 to validate and adapt welfare measures....
Development of an evidence-based welfare approach for cheetahs (Acinonyx jubatus) under human care

Dietary fatty acid composition significantly influenced the proactive-reactive behaviour of Senegalese sole ( Solea senegalensis) post-larvae
| Contributor(s):: Ibarra-Zatarain, Z., Morais, S., Bonacic, K., Campoverde, C., Duncan, N.
Few studies have examined the influence of diet on larval proactive-reactive behavioural dimension of stress coping style responses. The present study evaluated the influence of using different vegetables oils (Linseed; Soybean; Olive) and fish oil (Cod liver) for Artemia metanauplii nutritional...
Different strokes: can managing behavioral types increase post-release success?
| Contributor(s):: Watters, J. V., Meehan, C. L.
Re-introduction programs for endangered animals operate under the hope that protected habitats can sustain viable populations that rely little on humans. The goal of these programs is to supply animals with the resources and skills they need to succeed in the modern wild. However, predicting...
Do bottlenose dolphins display behavioural response to fish taste?
| Contributor(s):: Bouchard, Bertrand, Lisney, Thomas J., Campagna, Sylvie, Célérier, Aurélie
The chemosensory abilities (i.e. taste, smell and trigeminal perception) of odontocete cetaceans are still widely unknown. However, a better understanding of their potential use of these senses would not only improve our knowledge of their behavioural ecology, but also allow us to develop...
Do double cages and access to occupational materials improve the welfare of farmed mink?
| Contributor(s):: Hansen, S. W., Malmkvist, J., Palme, R., Damgaard, B. M.
The effects of cage enrichments and additional space were studied in 60 pairs of mink kits kept in standard cages (STD) and 67 pairs of mink kits kept in enriched cages (ENR). During the period from mid July to the end of September both groups had alternate access to one and two connected cages....

Does Enrichment Improve Well Being in Animals under Human Care? A Case Study of Two Harbor Seals (Phoca Vitulina)
| Contributor(s):: Vaicekauskaite, Ruta, Schneider, Jennifer N., Delfour, Fabienne
Harbor seals in the wild live in a stimulating environment; therefore, nonhuman-animal caretakers have increasingly been using environmental enrichment to improve the well being of seals under human care. The purpose of this study was to evaluate an object-based environmental enrichment program...
