Effect of Group Size on Activity Budgets of Colobus vellerosus in Ghana
Group size influences foraging efficiency in several primates. We examined the activity budgets of 3 groups of ursine colobus (Colobus vellerosus) at the Boabeng-Fiema Monkey Sanctuary (BFMS) in Ghana to determine whether larger group size induces scramble competition. We studied 2 groups (Bl; N = 7 – 8 and WW; N = 31 – 33) […]
Effect of dietary fiber concentration on apparent digestibility and digesta passage in non-human primates. II. Hindgut- and foregut-fermenting folivores
Abstract 10.1002/(SICI)1098-2361(1999)18:63.3.CO;2-6 Two test diets with different acid detergent fiber (ADF) concentrations (15% ADF, 30% ADF) were fed to seven adult hindgut- and seven adult foregut-fermenting primates. Apparent digestibilities (%) of dietary dry matter (DM), gross energy (GE), and fiber components (neutral detergent fiber [NDF], ADF, hemicellulose [HC], and cellulose [C]) were measured. Rates of […]
