Analysis of nutrients, moisture loss, and vitamin stability in primate browse harvested at the San Diego Zoo

The objective of this study was to obtain nutrient profiles along with insight on rates of moisture and vitamin loss in browse harvested at San Diego Zoo Global (SDZG). Ten species of browse commonly offered to colobines were manually separated into leaf and bark components for analysis at a commercial laboratory. Findings indicate that a variety of browse species and...

Nutritionally complete food-free diets for primates: potential benefits and concerns

Many zoos and institutions offer nutritionally complete foods (NCF) in the diets of captive primates (Oftedal and Allen, 1996). These foods, which often take the form of extruded biscuits, canned diets or gels, provide a source of important nutrients like protein, fat, fiber, vitamins and minerals, thereby helping to meet minimum estimated nutrient requirements (Oftedal and Allen, 1996; NRC, 2003)....

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...

Stronger than yesterday: new nutrient recommendations for lorisine primates

Asia’s slow lorises (Nycticebus spp.) are heavily impacted by the illegal wildlife trade in Southeast Asia. Confiscated lorises by Customs officials find themselves in rescue centers with approximately 50% of them having had their lower teeth removed by the poachers and must remain in the rescue centre indefinitely, if they survive. Reintroductions do occur but success is very low. Despite...

Fruit-free diets for primates

Paignton Zoo has been working towards fruit-free diets for primates since about 2003, when severe dental health issues in our colobus monkeys (Colobus guereza) triggered us to investigate sugar levels in their diet. In common with most of our primates at the time their diet consisted of a commercial primate pellet and included a high proportion of fresh and dried...

Examination of palatability of extruded primate diet using three flavors

Commercial diets are often essential parts of captive primate nutrition. However, consumption of dry extruded products can be difficult to encourage. Food and flavor preferences have been observed in captive primates and may be affected by palatability. This study examines the palatability of a commercial extruded primate diet when compared to 3 diets containing new flavors. Mazuri® Primate Browse Biscuit...
