Developing Children's Ability to Recognize Animal Emotions -- What Does It Take? A Study at the Zoo
Contributor(s):: Silvia Rochaw, Augusta Gaspar, Francisco Esteves
Several factors are known to affect children's identification of human emotions, but information is virtually inexistent regarding how they develop their ability to identify animal emotions. I this study we approached factors likely to influence children's identification of animal...
Rewarding memories? Behaviour of broiler chickens towards peat in flocks with and without previous exposure to peat
Contributor(s):: Vas, Judit, BenSassi, Neila, Vasdal, Guro, Newberry, Ruth C.
Under commercial conditions, environmental provisions assumed to have an enriching effect on broiler chicken welfare may be offered infrequently and at limited locations, raising questions about their enrichment value. We hypothesized that, if broilers given limited access to peat remembered peat...
Play behaviour reduced by environmental enrichment in fast-growing broiler chickens
Contributor(s):: Liu, Zhenzhen, Torrey, Stephanie, Newberry, Ruth C., Widowski, Tina
The objective of this study was to evaluate effects of environmental enrichment on play behaviour in fast-growing broiler chickens. Chicks (19 of each sex) were randomly assigned to 6 non-enriched (NE) pens and 6 pens enriched (E) with a raised platform, hanging weighing scale, peck stone, and...
Balancing skill against difficulty - behavior, heart rate and heart rate variability of shelter dogs during two different introductions of an interactive game
Contributor(s):: Arhant, Christine, Altrichter, Bernadette, Lehenbauer, Sandra, Waiblinger, Susanne, Schmied-Wagner, Claudia, Yee, Jason
Interactive games may boost positive well-being by combining the benefits of rewards with cognitive and social enrichment. However, a hasty introduction can lead to low success and frustration. We examine two methods of introducing an interactive game to dogs to test whether they elicit...
Visitors' perceptions of zoo-housed lesser anteater (Tamandua tetradactyla) welfare: Observation plays a larger role than a brief informative talk

Which types of rooting material give weaner pigs most pleasure?
Contributor(s):: Ocepek, Marko, Newberry, Ruth C., Andersen, Inger Lise
Provision of rooting material as enrichment for pigs has been primarily oriented towards reducing negative affect (suffering). Information is also needed on the impact of different types of rooting materials in promoting positive affect (pleasure). We hypothesised that repeated addition of fresh...
The ‘Cage Climber’ - A new enrichment for use in large-dimensioned mouse facilities
Contributor(s):: Vogt, Miriam Annika, Mertens, Sinja, Serba, Susanne, Palme, Rupert, Chourbaji, Sabine
Environmental Enrichment has been shown in experimental contexts to have clear and often beneficial effects on animal physiology and behavior. Housing prior to experiments can represent a large proportion of an animal’s living conditions, and improving housing conditions can be seen as...
Impact of a cattle brush on feedlot steer behavior, productivity and stress physiology
Contributor(s):: Park, Rachel M., Schubach, Kelsey M., Cooke, Reinaldo F., Herring, Andy D., Jennings, Jenny S., Daigle, Courtney L.
The aim of the present study was to investigate the impact of environmental enrichment (EE), in the form of a cattle brush, on feedlot cattle behavior, productivity and stress physiology. Steers were blocked by weight and assigned to one of two treatments 1) Cattle brush secured to fence line...
Use of space and behavior of weaned piglets kept in enriched two-level housing system
Contributor(s):: Fels, Michaela, Lüthje, Franziska, Faux-Nightingale, Alice, Kemper, Nicole
In this study, the possibility of introducing an elevated platform to a piglet pen was explored as a way of increasing available space and creating functional areas. On the platform, nine different manipulable materials were offered. In four batches, 40 weaned piglets were kept for five weeks in...
On-Farm Evaluation of an Automatic Enrichment Device with Maize Silage for Laying Hens
Contributor(s):: Giersberg, Mona Franziska, Kemper, Nicole, Spindler, Birgit
Challenges in alternative housing for laying hens are barren functional areas such as winter gardens and the occurrence of behavioral disorders. Environmental enrichment is a measure to deal with these problems. Therefore, an enrichment device offering maize silage automatically was tested in two...
Maternal Behavior, Posture Change, and Production Performance of Lactating Sows Housed in an Enriched Environment
Contributor(s):: Yi, Ran, Wang, Chao, Zhang, Xin, Zhao, Peng, Zhang, Mingyue, Li, Xiang, Cui, Shiquan, Liu, Honggui, Bao, Jun
This study aimed to evaluate whether adding straw to a loose-farrowing house promotes maternal functions and production. Forty-eight sows (Landrace× Large White) were housed in either a farrowing pen without straw (C, n = 24) or with straw (S, n = 24). Behaviors were observed using video...
Guardians' Knowledge and Husbandry Practices of Feline Environmental Enrichment
Contributor(s):: Alho, Ana Margarida, Pontes, Joana, Pomba, Constança
Feline environmental enrichment can prevent numerous disorders including anxiety, stress, obesity, and feline idiopathic cystitis. Despite its easy implementation and low cost, it has received little attention. The main goal of this study was to assess guardians' knowledge concerning feline...
Evaluation of Enrichment for Reptiles in Zoos
Contributor(s):: Eagan, Taylor
Studies on environmental enrichment for reptiles are lacking in the scientific literature. Although the literature reflects a limited take on reptile enrichment in the zoological community, it may not be the case in reality as enrichment is generally considered an important aspect of the care of...
Effects of environmental enrichment on activity and lameness in commercial broiler production
Contributor(s):: Vasdal, Guro, Vas, Judit, Newberry, Ruth C., Moe, Randi Oppermann
The aim of this pilot study was to investigate the effects of commercially applied environmental enrichments on behavior and lameness in broilers. Two consecutive flocks of broilers were observed at 16 days and 30 days of age to investigate differences between enriched (peat, bales of lucerne...
Effects of Enrichment Presentation and Other Factors on Behavioral Welfare of Pantropical Spotted Dolphin (Stenella attenuata)
Contributor(s):: Perez, Barbara C., Mehrkam, Lindsay R., Foltz, Amanda R., Dorey, Nicole R.
Environmental enrichment is a crucial element of promoting welfare for animals in captivity. However, enrichment programs are not always formally evaluated for their efficacy. Furthermore, there is little empirical evidence of enrichment evaluation for species of small cetaceans in zoological...
Effect of simple and low-cost enrichment items on behavioral, clinical, and productive variables of caged laying hens
Contributor(s):: Frediani, Mayra H., Pizzutto, Cristiane S., Alves, Maíra B. R., Pereira, Ricardo J. G.
Housing layers in battery cages is a practice still used by many countries but it has been criticized because of its influence on behavioral repertoire of birds. We investigated whether simple and affordable enrichment devices alone impact behavior, foot condition and performance of laying hens...
Assessment of environmental enrichment for different primate species under low budget: A case study
Contributor(s):: Costa, R., Sousa, C., Llorente, M.
The 2011 European Union Zoo Inquiry presented evidence that most zoos fail to achieve adequate levels of nonhuman animal welfare. Appropriate environmental enrichment (EE) can play a role in the promotion of welfare. However, financial and staff constraints frequently make it challenging to...
Visitor Perceptions of Nature Conservation at Helsinki Zoo
Contributor(s):: Ojalammi, Sanna, Nygren, Nina V.
These days zoos often claim that their main objective is the promotion of nature conservation and that they strive to educate their visitors about animals and nature conservation. But how do zoo visitors themselves perceive this emphasis on conservation education? In order to determine how...
