Nutritional Composition of Fruits Selected by Long-Tailed Macaques () in Kuala Selangor, Malaysia.

Proximate analysis of twelve species of fruits commonly consumed by long-tailed macaques (), i.e., , , , , , , , , sp., , ssp. and , was conducted with the specific objective to determine the nutritional composition of the foodstuffs of long-tailed macaques. The results showed the following order of nutrients: fibre, protein, fat and ash. Based on the results of the chemical analysis, the highest percentage of fibre content (52.7%), protein (9.9%), fat (77.2%) and ash (8.5%) were found in , , and , respectively. The nutrient composition of these twelve fruit species was found to differ (ANOVA test: crude protein, F (11,24) = 87.978, < 0.05; crude fibre, F (11,24) = 28.886, < 0.05; crude fat, F (11,24) = 2081.396, < 0.05 and ash, F (11,24) = 41.011, < 0.05). Fibre was found in the highest amount among the four types of nutrients studied. Here, had the highest relative fibre content of all tested fruits, had the highest fat content, had the highest protein content, and the total mineral content was highest in .
