| Popis: | The goals of this study were to determine digestibility of a bamboo diet by giant pandas (Ailuropoda melanoleuca) and to evaluate potential internal markers (naturally occurring markers in their diet) for their ability to estimate fecal output and digestibility. Digestibility predictions using internal markers were based on either feed offered or feed consumed. Two giant pandas were used in 1-, 2-, and 3-day digestibility trials with total collection of feces. In the 3-day trial, animals were fed 100% bamboo with no dietary supplements. In all other trials, supplements were included in addition to bamboo. The 3 internal markers chosen for evaluation were acid insoluble ash (AIA), acid detergent lignin (ADL), and acid detergent insoluble nitrogen (ADIN). Results from digestibility trials indicated that apparent nutrient digestibility could be determined with no differences (P > 0.05) between pandas. Six apparent dry matter (DM) digestibility values ranged from 6.9 to 38.5%. Apparent DM digestibili... |
