A perspective on ungulate management and welfare assessment across the traditional zoo to large landscape spectrum.

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 ungulates across these settings. Differing housing and management scenarios present different challenges and opportunities in terms of welfare but this commentary posits that good welfare is possible in all of these settings. In this commentary, we also consider natural behaviors that may, at face value, compromise welfare and discuss how taking a long view on welfare addresses concerns about these behaviors, in part using arguments related to normal behavioral development that likely improves welfare at other life stages. We also highlight the role of motivation in seemingly welfare-compromising behaviors. Finally, some indicators of welfare that we believe transcend management scenarios, and are thus able to be compared across scenarios, are suggested.

Successful assisted rearing and reintegration of a blue wildebeest calf into a managed herd prior to weaning.

The blue wildebeest (Connochaetes taurinus; Burchell, 1823) is an African ungulate that is notoriously difficult to hand-rear and reintegrate into managed herds. The following case report is of a female wildebeest neonate that was orphaned, bottle-reared, and successfully reintroduced into a herd at a zoological facility. Since blue wildebeests are a highly precocial and herd-oriented species that calve synchronously in the wild as a reproductive strategy to maximize survival, early release of assist-reared neonates into managed herds before weaning may be an effective strategy for increasing the chance of acceptance. Wildebeest calves can also be easily trained for bottle-feedings in the field to facilitate early release. Due to a lack of literature on the assisted rearing and reintegration of wildebeest calves into managed herds, this case report provides useful techniques for the feeding, training, and releasing of bottle-reared wildebeests that may also be applicable to other assist-reared herd species at zoological facilities.
