A perspective on ungulate management and welfare assessment across the traditional zoo to large landscape spectrum
Abstract Wild ungulates are managed in human care in a range of settings from traditional zoos to large ranches. These varied settings present different portfolios of risks for good or poor welfare, which leads some to question whether a particular setting is ?good for welfare? and have frustrated others interested in comparing the welfare of […]
Discrimination of Acoustic Stimuli and Maintenance of Graded Alarm Call Structure in Captive Meerkats
Animals living in human care for several generations face the risk of losing natural behaviors, which can lead to reduced animal welfare. The goal of this study is to demonstrate that meerkats (Suricata suricatta) living in zoos can assess potential danger and respond naturally based on acoustic signals only. This includes that the graded information […]
Assessing Animal Welfare with Behavior: Onward with Caution
An emphasis on ensuring animal welfare is growing in zoo and aquarium associations around the globe. This has led to a focus on measures of welfare outcomes for individual animals. Observations and interpretations of behavior are the most widely used outcome-based measures of animal welfare. They commonly serve as a diagnostic tool from which practitioners […]
The Natural Behavior Debate: Two Conceptions of Animal Welfare
The performance of natural behavior is commonly used as a criterion in the determination of animal welfare. This is still true, despite many authors having demonstrated that it is not a necessary component of welfare – some natural behaviors may decrease welfare, while some unnatural behaviors increase it. Here I analyze why this idea persists, […]
Captivity effects on wide-ranging carnivores
Some species — ring-tailed lemurs and snow leopards, for example — apparently thrive in captivity, whereas others, such as Asian elephants and polar bears, are prone to problems that include poor health, repetitive stereotypic behaviour and breeding difficulties. Here we investigate this previously unexplained variation in captive animals’ welfare by focusing on caged carnivores, and […]
Stimulating Natural Behavior in Captive Bears
Brown bears (Ursus arctos) in zoos are often kept under sub-optimal conditions and have behavioral time-budgets that differ from their wild counterparts. We conducted 2 experiments using novel feeding conditions for captive European brown bears (scattering food rather than piling and increasing feeding frequencies from 3 to 6/day) in the Bear Forest (BF), a 2-ha […]
Assessing the importance of natural behavior for animal welfare
The concept of natural behavior is a key element in current Dutch policy-making on animal welfare. It emphasizes that animals need positive experiences, in addition to minimized suffering. This paper interprets the concept of natural behavior in the context of the scientific framework for welfare assessment. Natural behavior may be defined as behavior that animals […]
Natural living—a precondition for animal welfare in organic farming
This article discusses animal welfare in organic farming systems in relation to values and aims in organic farming. It sums up experiences from a 4-year interdisciplinary project. An important finding is that animal welfare is understood somewhat differently in organic farming from what is common in conventional agriculture. It is interpreted in terms of natural […]
Encouraging natural feeding behavior in captive-bred black and white ruffed lemurs (Varecia variegata variegata)
Captive breeding of endangered species is commonly proposed as a means of conserving biodiversity. The suggestion is that captive populations can be built up to provide individuals to reinforce or re-establish wild populations. However, there is evidence to suggest that captive-bred animals lack the skills necessary for survival in their natural habitat. This research was […]
Review of wallowing in pigs: Implications for animal welfare
Most modern production systems, especially in temperate climates, do not offer wallowing facilities to pigs and, to date, this has neither generated much concern in welfare science nor public debate on pig welfare. Nevertheless, wallowing is a natural behaviour of pigs which may be important to them. This paper systematically examines the overall importance of […]
