Abstract: Natural behavioural biology and birth origin were investigated as risk factors for stereotypic behaviour and infant mortality in captive carnivore species. The data for natural behavioural biology, stereotypic behaviour, and captive infant mortality were obtained from literature searches and previously compiled databases. It was found that home-range size, daily distance travelled and chase distance predicted stereotypic behaviour, but not infant mortality. Analyses investigating the interaction between birth origin and natural behavioural biology for stereotypic behaviour were inconclusive due to small sample sizes. In addition, a comprehensive literature review was conducted for birth/hatch origin effects across any/all species. This survey found that captive-born/hatched individuals tended to be more prone to pathologies and wild-caught individuals may have poorer welfare. In conclusion, carnivore species that are wide-ranging or have long chase distances are particularly susceptible to developing stereotypic behaviour in captivity, and birth/hatch origin appears to predict welfare and some forms of pathology.
