WHAT WE KNOW
Where they live: Southeastern Brazil Tropical, Rainforest Inhabit secondary lowlands, evergreen, and semi-deciduous forests, forest edge and dry forest patches. Typically live at elevations between 1600 – 2300 feet but can be found as high as 2600 feet. Arboreal Rowe, 1996; Rylands and Mendes, 2008
WHAT WE KNOW
Social Behavior: Live in family groups, up to 8-10 individuals Usually monogamous, only dominate male and female typically breed Groups are usually comprised of a breeding pair and their offspring Daughters are usually reproductively suppressed
Wakenshaw, 1999
WHAT WE KNOW
Wild diet: Anatomical and behavioral adaptations for tree- gouging Able to gouge into tree trunks, branches, and vines to obtain gum Eat plant gums, insects and fruit Also eat flowers, nectar, frogs, snails, lizards, and spiders.
Passamani & Ryland, 2000; Passamani, 1998; Rowe, 1996; Rylands and Mendes, 2008
IN THE WILD
Passamani & Ryland, 2000 One year study, that included 9,013 observations of which 1848 were of feeding Group sized varied from 3 – 5. 68.6% of all feeding observations were gums 15% fruit 14.6% invertebrates 0.8% small vertebrates 1% unidentified
FEEDING CHOICES IN THE WILD
Animals eat gum and insects year around
During the wet season, Dec & Jan, selection of fruit greatly increases (43% of feeding observations) but animals continue to consume gums and insects
Passamani & Ryland, 2000
IMPORTANT KEY POINTS FOR APPROPRIATELY FEEDING CAPTIVE GEOFFROY’S MARMOSETS
1. Fruit will be preferentially consumed when available 2. Wild marmosets use their teeth to gouge or gnaw holes in trees and vines for gum 3. Animals are usually monogamous and the breeding pair are dominant 4. Subordinate females are reproductively suppressed

Fruit was consumed by wild Geoffory’s 15% of the observations; however, the majority of these observation were during only 2 months of the year. Although fruit can be used for positive re- enforcement or the delivery of medicine it should be very limited. Geoffroy’s WILL consume fruit preferentially and to their detriment.

Presentation of the food is AS important as the food itself First morning Feed - ONLY base diet, establish how much of the base diet your group needs to consume 20 -25 grams/animal works well for most groups offered either Mazuri or ZuPreem Once the amount of base diet needed is consumed begin offering the activity foods Best to offer activity foods as well as additional base diet over at LEAST 2 feedings so a minimum of 3 food offerings/day. MAKE THE ANIMALS WORK FOR ALL THEIR FOOD INCLUDING THE BASE DIET
OTHER
It is not unusual for subordinate females to become very heavy – may have to do with suppressed ovulation but we don’t know Target feeding at risk animals their base diet is highly recommended Weigh your animals OFTEN at least once a month – best way to identify issues early and address them before they become problems Consider the diets of other species in the exhibit – only combine dietary compatible animals Giardia parasite as well bacterial pathogens and GI autoimmune diseases MAY be diet related GUM

Soluble fiber absorbs water In humans: Soluble fiber attaches to cholesterol particles and takes them out of the body, helping to reduce overall cholesterol levels Contributes to gut fill or the feeling of being satiated Aids in healthy bowel movements, absorbs water as it passes through the gut and contributes to stool bulk and helps prevent constipation Is protective against diabetes – because it is not well absorbed it does not contribute to blood sugar spikes which is a risk factor for both type 2 diabetes and heart disease Gums are β-linked polysaccharides that require microbial fermentation**
PRIMATE MICROBIOME PROJECT HTTP://WWW.PRIMATEMICROBIOME.ORG/
ASSOCIATIONS BETWEEN NUTRITION, GUT MICROBIAL COMMUNITIES, AND HEALTH IN NONHUMAN PRIMATES Jonathan Clayton, University of Minnesota Primate gastrointestinal tract is home to trillions of bacteria
. Digestion and metabolism . Immune system development . Pathogen resistance
Shifts in the microbiome are correlated with GI autoimmune diseases such as:
. Diabetes . Crohn’s disease . Ulcerative colitis Clayton, 2015
GOAL OF THE PRIMATE MICROBIOME PROJECT
Compare the microbiome wild and captive animals within the same species
Determine whether shifts in the microbiota are linked with health (e.g., gastrointestinal) in captivity.
Hopefully develop predictive biomarkers for certain primate diseases, including those linked to diet. Clayton, 2015
