Effect of dietary fiber concentration on apparent digestibility and digesta passage in non-human primates. I. Ruffed lemurs (Varecia variegate variegate and V. v. ruba)
Two test diets with different fiber concentrations (15% acid detergent fiber [ADF], 30% ADF) were fed to five adult female ruffed lemurs (Varecia variegata). Apparent digestibility (%) of dry matter (DM), gross energy (GE), and fiber components (neutral detergent fiber [NDF], ADF, hemicellulose [HC], and cellulose [C]) were measured. Rates of digesta transit (TT1) and retention time (RGIT) were assessed...
