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 ±...

Viverrid digestive physiology: comparison of binturongs (Artictis binturong) and dwarf mongoose (Helgale parvula)

A preliminary investigation was conducted to compare intake and digestion in the largest and smallest members of the Viverridae family, highly frugivorous binturongs (Arctictis binturong; n=2) and the more carnivorous dwarf mongoose (Helogale parvula; n=6) housed in groups. Normal zoo diets were monitored over two 4-day periods, with total feed intake and fecal output measured.

When to feed on gums: temporal patterns of gummivory in wild tamarins, Saguinus mystax and Saguinus fuscicollis (Callitrichiae)

This study examines the temporal patterning of gum feeding in two species of sympatric tamarin monkeys, Saguinus mystax and Saguinus fuscicollis, during the diurnal activity period. The number and duration of visits to gum sources and number of gum feeding records are used as parameters to analyze the gum feeding itinerary. Both visits to gum sources and gum feeding records...
