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...

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...

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...

DIET DIGESTIBILITY IN COLOBINE MONKEYS: IMPLICATIONS FOR DIETS AND DIETARY RECOMMENDATIONS

This study quantified the composition and diet digestibility of 19 diets consumed by 11 groups of colobine monkeys (four species: Colobus guereza, Trachypithecus obscurus, Colobus angolensis, and Rhinopithecus bieti) in the US and in China. Each digestibility trial had a 10- day adaptation period and a three-day collection period. The diets consumed averaged 17.1 ± 0.9% crude protein, 24.4 ±...

Chemical composition of foods eaten by African colobines compared with Southeast Asian colobines

Nutritional analyses of foods eaten by wild colobine populations can be useful for understanding colobine nutritional needs, crucial for successful maintenance of captive populations. A previous report by Nijboer et al. summarized the mineral and proximate data for browse composition of three species of Southeast Asian colobines. The authors noted that the diets of these wild colobines contained substantially more...

The influence of plant chemistry on browse choice in Angolan Colobus Monkeys (Colobus angolensis palliates)

Browse is included in the diets of many primate species, especially those that consume large portions of leaf material under free-ranging conditions. The challenge of providing a reliable source of browse is complicated by the limited availability of plant species that are nutritionally adequate, palatable, and available in suitable quantities to meet the demands of the animal collection.

Ingestion of Viburnum x rhytidophylloides ‘Alleghany’ potentially lethal to White-Mantled Black Colobus (Colobus guereza)

In December of 2000, three white-mantled black colobus (Colobus guereza) housed at the Denver Zoological Gardens began showing indications of pain, and as a result, were removed from their facility and hospitalized. One animal died of gastric ulcers, however the others recovered with treatment. Light microscopic evaluation of gastric biopsies from one of the monkeys, showed inflammation of the mucosal...

Comparison of diets fed to Southeast Asian colobines in North American and European zoos, with emphasis on temperate browse composition.

In May and June 1994 a survey of diets fed to captive southeast Asian colobines in European (n = 12) and North American (n = 9) zoos was conducted. Most diets were very complex, comprising an average of 25 ingredients; 149 different foods were listed in responses. Comparison of diets fed showed that European zoos feed a greater variety of...

Browse species preference and palatability of Colobus guereza kikuyuensis at the Denver Zoological Gardens

In the wild, folivorous primates have access to leaves of many different species. At the Denver Zoological Gardens (DZG), in Denver, Colorado, Colobus guereza kikuyuensis primates consume most vegetation presented to them, thus maintenance of vegetation in an animal exhibit is challenging. It is observed that insufficient browse often results in behavior concerns such as pacing or lack of mental...

Chemical composition of Southeast Asian Colobine foods

Digestive disturbances have been considered a major health issue among captive colobines [Janssen, 1994; Calle et al., 1995]. Inadequate or inappropriate fiber sources may underlie some of these problems. Apart from maintaining normal gastrointestinal function [Van Soest, 1994 ], one critical issue in husbandry of these species is the necessity of providing a suitable diet for supporting pregastric [Stevens, 1988]...

Leaf-eating primates: nutrition and dietary husbandry

Species differences in natural feeding habits and digestive system structure suggest that all captive primates should not be fed in the same manner.28 Primates whose diets consist primarily or exclusively of leaf material possess highly developed, and delicately balanced digestive systems, which enable them to utilize this abundant food source. The order of Primates consists of several species whose natural...

Comparison of diets fed to South-East Asian Colobines in North American and European Zoos Versus Natural Diets
