Comparative feeding and nutrition in captive, non-human primates.

1. Food intake studies were carried out on three groups of captive primates (anthropoid apes (Pongidae), lemurs (Lemuridae) and marmosets (Callitrichidae). 2. Determination and analysis of the nutrient intakes were carried out by calculations based on food tables. The results from all groups were compared. 3. Marmosets were found to have higher intakes of energy and many other nutrients than the apes and lemurs. 4. The results suggest that there is a tendency towards over use of dietary supplements and foods of higher nutrient density for captive primates.
