Associations between diet, gut microbial communities, and health in red-shanked doucs (Pygathrix nemaeus): a model for the subfamily colobinae

Red-shanked doucs (Pygathrix nemaeus) and other colobines possess specialized gastrointestinal systems similar to ruminants. They utilize both fore- and hindgut fermentation to meet their energetic demands. Maintenance of captive populations has been largely unsuccessful. Improving captive conditions is hindered by critical gaps in our understanding of their natural diet and enteric microbial adaptations that facilitate the digestive process. We used...

Nutrition therapy for human gastrointestinal disorders and application to captive non-human primates

Abnormal gastrointestinal function is considered to be a common problem among captive non-human primates. Certain nutrients and diet patterns are implicated in abnormal gastrointestinal function and disease. The human nutrition field uses medical nutrition therapies to prevent and/or manage a variety of gastrointestinal disorders. Some of these may be appropriate for application to non-human primates. Current evidence-based nutrition interventions for...

CD-ROM teaching unit on the digestive system of vertebrates

The present-day vertebrates are comprised of approximately 45,000 species of fish, amphibians, reptiles, birds and mammals that have adapted to a wide-range of freshwater, marine, and terrestrial habitats. Their digestive system provides for the assimilation of the energy and nutrients required for maintenance, growth, and reproduction. This is accomplished by complex series of episodic events that reduce food to a...
