Formatted abstract
Food selection is one of the most basic aspects of a primate's ecology, particularly in their natural habitat Several factors Influence food selection of colobine monkeys, of which nutritional factors, especially protein, fibre and secondary compounds are considered key determinants. While some colobines are food selective, black-shanked douc langurs (Pygathrix nigripes) consume a wide range of parts of many plant species. However, the influence of phytochemistry on food choice has not yet been analysed for these doucs in their natural habitat. Based on our studies on feeding ecology of the black-shanked douc langurs in southern Vietnam we collected 15 leaf and two fruit samples of food plants and six leaf samples of non-food plants that occur in high density in the study area where the black-shanked douc iangurs are the largest common folivore. Samples were analysed for protein, fibre, condensed tannlns, ash, and necessary base group and trace group of minerals. The resuks showed that digestible fibre (cellulose and hemicellulose) was higher In food plants but there were no statistically significant differences for any other comparison. There is no evidence to suggest that the doucs were foraging strategically to maximise their protein or energy Intake, most viable population after that of Khau Ca.
