Includes structural, behavioral, food, and auditory enrichment.
Birds kept in commercial production systems can be exposed to multiple stressors from early life and this alters the development of different morphological, immunological and behavioural indicators. We explore the hypothesis that provision of a...
A recent large-scale welfare study in North America involving 106 Asian (Elephas maximus) and 131 African (Loxodonta africana) elephants at 64 accredited facilities identified links (i.e., risk factors) between zoo environmental factors and a number...
Elephants experience a number of health issues that can contribute to their well-being and survival. In managed populations, housing conditions and management practices can influence individual health, so potential risk factors associated with morbidity or...
EC Directive 2001/93 requires that all pigs have access to proper investigation and manipulation materials. Intensively farmed pigs in Europe are frequently provided with a short metal chain with or without an indestructible object attached...
Zoos play a vital role in managing and conserving a wide range of threatened species and in enhancing their populations in natural habitats through captive breeding and reintroduction programmes. Most small felids are poor breeders...
The current study tested the effect of voluntary running on future anxiety-like behavior, physiological response to stress, and ethanol intake/preference, while including a chronically stressed group and healthy group housed conspecifics. When given concurrently, voluntary...
Cardiovascular exercise (CVE) is associated with healthy aging and reduced risk of disease in humans, with similar benefits seen in animals. Most rodent studies, however, have used shorter intervention periods of a few weeks to...
There is an increasing amount of consideration being paid to cattle welfare and enrichment, both at agricultural research institutions and via welfare audits on commercial operations. A crucial element of these welfare and enrichment evaluations...
In order to provide research dogs enrichment at our facility, veterinary staff suggested adapting the adjacent space to our dog housing buildings to allow for more species-specific behavior by creating an exercise area that both...
At the University of Oklahoma Health Sciences Center, Department of Comparative Medicine, we have a large captive colony of Olive Baboons (Papio anubis). Environmental enhancement is an integral part of the Comparative Medicine Baboon Research...
