Complexities of Using Wild versus Captive Activity Budget Comparisons for Assessing Captive Primate Welfare

Activity budget comparisons between groups or individuals in the wild and those in captivity are commonly used to determine the range of wild-type behaviors that nonhuman animals in captivity perform. These comparisons are conducted with the view that individuals displaying a greater range of wild-type behaviors have enhanced welfare. Such comparisons have a greater appeal […]

Technical Contribution: A Cautionary Note on the Use of Behavioural Diversity (H-Index) in Animal Welfare Science

Animal welfare scientists actively seek reliable and practical metrics that can serve as indicators of animal welfare for use with agricultural, laboratory and zoo-housed animals. Behavioural diversity as a welfare concept originated from early welfare scientists linking poor animal welfare with a high proportion of time spent engaged in stereotyped behaviours and little expression of […]

Well-Being of Nonhuman Primates in Research


Training Nonhuman Primates to Cooperate With Scientific Procedures n Applied Biomedical Research

This report provides a brief overview of aspects of training nonhuman primates who have been, and continue to be, used in this laboratory. The research context involves applied behavioral studies in which animals are trained to perform complex operant behavioral sequences, often in their homecage environment. In such studies, animals have freedom to choose whether […]

The effects of predictable and unpredictable feeding schedules on the behavior and physiology of captive brown capuchins (Cebus apella)

Responses to different feeding schedules in group living capuchins (Cebus apella) were evaluated. Animals were fed on a predictable schedule for 6 weeks followed by 6 weeks on an unpredictable schedule (varied by early, on-time, or late feedings). Behavior was sampled via scan sampling at 1 min intervals 1 h pre-feed and 1 h post-feed. […]

The Physiological and Behavioral Impact of Sensory Contact Among Unfamiliar Adult Mice in the Laboratory

Housing mice in the laboratory in groups enables social interaction and is the way a laboratory should house mice. However, adult males show reciprocal aggression and are therefore frequently housed individually. Alternatively, a grid divider, which allows sensory contact by sight and smell but prevents fighting and injuries, can separate mice within 1 cage. This […]

Feeding live prey to zoo animals: response of zoo visitors in Switzerland

Abstract 10.1002/zoo.20261.abs In summer 2007, with the help of a written questionnaire, the attitudes of more than 400 visitors to the zoological garden of Zurich, Switzerland, toward the idea of feeding live insects to lizards, live fish to otters, and live rabbits to tigers were investigated. The majority of Swiss zoo visitors agreed with the […]

Commentary: Improving well-being for captive giant pandas: Theoretical and practical issues

Abstract 10.1002/zoo.10111.abs Here we present the outcome of a panel discussion from Panda 2000, an International conference held in San Diego, California. The discussion addressed how to use animal motivation theory to develop enrichment programs that will improve physical and psychological well-being for giant pandas in captivity. Wild animals held in captivity too often develop […]
