The Longevity Legacy: The Challenges of Old Animals in Zoos

As knowledge of husbandry has improved with the keeping of wild animals in zoos over the last 200 years, so longevity has also improved, bringing with it challenges owing to the development of pathologies associated with ageing. In this chapter, the principal skeletal and dental pathologies of aged zoo mammals are described, and the results […]

Differences in fecal particle size between free-ranging and captive individuals of two browser species

Abstract 10.1002/zoo.20161.abs Data from captive animals indicated that browsing (BR) ruminants have larger fecal particles—indicative of lesser chewing efficiency—than grazers (GR). To answer whether this reflects fundamental differences between the animal groups, or different reactions of basically similar organisms to diets fed in captivity, we compared mean fecal particle size (MPS) in a GR and […]

A comparison of the occurrence of common dental abnormalities in stabled and freegrazing horses

The purpose of this study was to gain evidence on the prevalence of dental abnormalities in stable-kept horses in comparison with free-living horses. It is expected that free-living horses that graze for as much as 16 h/day will have fewer dental abnormalities than stable-kept horses. In this study, the latter group was fed a diet […]

A comparison of the occurrence of common dental abnormalities in stabled and free-grazing horses

The purpose of this study was to gain evidence on the prevalence of dental abnormalities in stable-kept horses in comparison with free-living horses. It is expected that free-living horses that graze for as much as 16 h/day will have fewer dental abnormalities than stable-kept horses. In this study, the latter group was fed a diet […]
