Environmental enrichment: an experiment in biosocial intervention
Contributor(s):: Chiapperino, Luca
Access to chewable materials during lactation affects sow behaviour and interaction with piglets

Pigs with but not without access to pieces of recently harvested wood show reduced pen-mate manipulation after a provision of feed and straw
Contributor(s):: Telkanranta, Helena, Valros, Anna
In barren environments of commercial farms, pig often redirect their rooting and chewing behaviours at other pigs, which can lead to tail biting. When materials such as straw are provided, the quantity is usually too small to have an effect. The aim of this study was to test whether small...
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....
Provisioning of live black soldier fly larvae (Hermetia illucens) benefits broiler activity and leg health in a frequency- and dose-dependent manner
Contributor(s):: Ipema, Allyson F., Gerrits, Walter J. J., Bokkers, Eddie A. M., Kemp, Bas, Bolhuis, J. Elizabeth
Fast-growing broilers spend most their time inactive and are therefore prone to experience leg problems. Environmental enrichment that facilitates intrinsically motivated behaviours can potentially promote activity and reduce leg problems, thereby improving broiler welfare. A promising...
Efforts to Ban the Routine Tail Docking of Pigs and to Give Pigs Enrichment Materials via EU Law: Where Do We Stand a Quarter of a Century on?
| Contributor(s):: Elena Nalon, Nancy De Briyne
In its role as guardian of the Treaties, the European Commission must ensure that Member States enforce EU law within their territories. If adequate enforcement is found to be wanting, the Commission also has the power to take infringement procedures as a corrective measure. The case of...
Tailored Enrichment Strategies and Stereotypic Behavior in Captive Individually Housed Macaques (Macaca spp.)
| Contributor(s):: Cannon, Tessa H., Heistermann, Michael, Hankison, Shala J., Hockings, Kimberley J., McLennan, Matthew R.
The welfare of nonhuman animals in captivity is widely dependent on the natural psychological, physical, and behavioral needs of the animals and how adequately these needs are met. Inability to engage in natural behaviors can lead to chronic stress and expression of stereotypic behavior. The...
Safewalk: Improving Enrichment and Adoption Rates for Shelter Dogs by Changing Human Behavior
| Contributor(s):: Bright, Terri M., Hadden, Louise
Shelter dogs are typically cared for by staff and volunteers. At the Boston location of the Massachusetts Society for the Prevention of Cruelty to Animals, prior to 2009, any member of the public who was older than 16 years of age and attended 1 orientation could walk dogs available for adoption....
Olfactory Enrichment in California Sea Lions (Zalophus californianus): An Effective Tool for Captive Welfare?
| Contributor(s):: Samuelson, Mystera M., Lauderdale, Lisa K., Pulis, Kelly, Solangi, Moby, Hoffland, Tim, Lyn, Heidi
In the wild, California sea lions (Zalophus californianus) are exposed to a wide variety of sensory information, which cannot be replicated in captive environments. Therefore, unique procedures are necessary for maintaining physiological and psychological health in nonhuman animals in captivity....
Long-Term Macroevaluation of Environmental Enrichment in Three Brown Bears (Ursus arctos) at Barcelona Zoo
| Contributor(s):: Soriano, Ana I., Vinyoles, Dolors, Maté, Carmen
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 enrichment to compare the baseline and enrichment phases. Focal sampling...
Instituting Dark-Colored Cover to Improve Central Space Use Within Guinea Pig Enclosure
| Contributor(s):: Byrd, Charles P., Winnicker, Christina, Gaskill, Brianna N.
Domestic guinea pigs (Cavia aperea f. porcellus) in laboratories have been shown to actively avoid the centers of their cages. This experiment tested a novel, dark-colored “shader” placed over the central portion of a cage. Based on the observed behavior of wild guinea pig species, it was...
Improving the Welfare of a Zoo-Housed Male Drill (Mandrillus leucophaeus poensis) Aggressive Toward Visitors
| Contributor(s):: Martín, Olga, Vinyoles, Dolors, García-Galea, Eduardo, Maté, Carmen
Improving the welfare of nonhuman animals in captivity and maintaining behavioral competence for future conservation purposes is of the highest priority for zoos. The behavior of an aggressive male drill (Mandrillus leucophaeus poensis) was assessed in Barcelona Zoo. The 2-year study presented in...
Environmental Enrichments for a Group of Captive Macaws: Low Interaction Does Not Mean Low Behavioral Changes
| Contributor(s):: Reimer, Jéssica, Maia, Caroline Marques, Santos, Eliana Ferraz
Environmental enrichment has been widely used to improve conditions for nonhuman animals in captivity. However, there is no consensus about the best way to evaluate the success of enrichments. This study evaluated whether the proportion of time spent interacting with enrichments indicated the...
Environmental Enrichment Effect on Fecal Glucocorticoid Metabolites and Captive Maned Wolf (Chrysocyon brachyurus) Behavior
| Contributor(s):: Coelho, Carlyle Mendes, Azevedo, Cristiano Schetini de, Guimarães, Marcelo Alcino de Barros Vaz, Young, Robert John
Environmental enrichment is a technique that may reduce the stress of nonhuman animals in captivity. Stress may interfere with normal behavioral expression and affect cognitive decision making. Noninvasive hormonal studies can provide important information about the stress statuses of animals....
Effects of Calf Horn as Chews on the Behavior of Laboratory Dogs
| Contributor(s):: Ketter, Daphne A., Klima, André, Küchenhoff, Helmut, Dobenecker, Britta, Schmidt, Jörg, Erhard, Michael H., Döring, Dorothea
It is increasingly required that non-human animals in laboratories are provided with adequate enrichment to promote the welfare of the animals. In a previous publication we showed that laboratory dogs intensively used the horn of calf hooves as chewing objects. In this report, we describe the...
Does the location of enrichment material affect behavior and dirtiness in growing female pigs?
| Contributor(s):: Dalmau, Antoni, Areal, Bruno, Machado, Silvana, Pallisera, Joaquim, Velarde, Antonio
The objective of this study was to investigate if female growing pigs spend similar amounts of time exploring a wooden stick as they do exploring enrichment material regardless of its proximity to the feeder. Forty-eight pigs aged 18 to 26 weeks allocated to 16 pens with three pigs per pen were...
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...
Behavior and Welfare of Domestic Cats Housed in Cages Larger than U.S. Norm
| Contributor(s):: Stella, Judith L., Croney, Candace C., Buffington, C. Tony
The effect of providing additional floor space on cat behavior and welfare is not well documented. This study involved replication of an investigation of cats’ responses to enhanced cage and room environments using cages of 0.56 m2 with the same methodology but an increased space allowance of 1.1...
