Baseline Intake Study for Four Species of Primates in Captivity: Callithrix pygmaea, Nycticebus pygmaeus, Propithecus coquereli and Callithrix geoffroyi

Little information is known in regards to the natural or seasonal diets of primates. In captivity, nutrition can be an important part of preventative medicine and lead to an improved quality of life for primates.
