The need for a convergence of agricultural/laboratory and zoo-based approaches to animal welfare

Advances in animal welfare science have led to a high number of studies published for farm, laboratory and zoo animals, with a huge breadth of innovative topic areas and methodologies. This paper investigates the different approaches used to undertake welfare research in farm, laboratory and zoo animals due to the variety of constraints that each group brings. We also set recommendations to how groups can support each other in moving forwards to reduce animal suffering and promote a life worth living, a goal that all parties aim to achieve. We propose that researchers develop more collaborations across species, in particular to focus on the applied component of animal welfare and utilizing positive welfare indicators; facilitate knowledge transfer and share good practice worldwide; and accept small n based studies that can still be scientifically robust and provide individual-based steps into advances in our knowledge. Ultimately, we need to be progressing animal welfare science to a point beyond legislative needs, and ensure that ‘high animal welfare’ becomes an additional mission statement for all animal-based industries

Self-injurious behaviour in zoo primates

Researchers have long known that social isolation of some primates, particularly in infancy, can lead to the development of abnormal behaviors including self-injurious behavior (SIB). However, SIB can also occur in non-isolate-reared primates and can be triggered by frustration or environmental events. The subjects of reports of SIB have mostly been laboratory primates, usually macaques. Researchers had not systematically studied whether SIB occurs in zoo primates, and if so to what extent. Here we report the results of a questionnaire-based survey of British and Irish zoos on the extent of SIB in zoo primates, and whether it was associated with any environmental or developmental events. Responses indicated that though SIB occurred across a range of primate species, its incidence was very low. Respondents identified a variety of environmental events as implicated in initiating SIB, and though the data set is too small to confirm them statistically, several trends were discernible. We conclude that SIB is not a major problem in zoo primates
