Play behavioural tactics under space reduction: social challenges in bonobos, Pan paniscus
Several studies have suggested that primates vary in their response to spatial reduction, which represents a challenge for captive animals. Under spatial reduction, primates can adopt various strategies to reduce social tension. Such strategies, which are not mutually exclusive, can involve avoidance and coping tactics. Recently, it has been shown that, during short-term crowding, bonobos […]
Cage Design and Forms of Play in Red-Bellied Tamarins, Saguinus labiatus
Abstract 10.1002/zoo.1430110310.abs We investigated the role of cage design in the expression of play in a group of red-bellied tamarins (Saguinus labiatus). For each of the four play behaviors that were measured in this study (wrestle, pounce, grasp, and chase), significant differences in frequency appeared as a function of substrate. When playing on broad, flat, […]
Comparison of the behaviour of piglets raised in an artificial rearing system or reared by the sow
Over the last 15 years, rising sow fertility has led to a considerable increase in litter size. As a consequence, the number of live born piglets may outnumber the number of functional teats, and surplus piglets are removed from the sow at the age of 3–6 days and fed with artificial milk. The objective of […]
