The apparent digestibilities of macronutrients by babirusa (Babyrousa babyrussa) were measured. Three group-housed captive babirusa were fed a diet of pelleted feed, boiled potatoes, grains, vegetables, and fruits. To determine reproducibility of the results, two digestibility trials were conducted 5 wk apart. The apparent digestibilities for crude protein, crude fat, and nonstructural carbohydrates (nitrogen-free extract) were 71, 76, and 78% of intake, respectively. Average apparent digestibilities of neutral detergent fiber and acid detergent fiber were 62 and 19% of intake, respectively. Hemicellulose (neutral detergent fiber minus acid detergent fiber) digestibility was 75%. Cellulose digestibility on average was 19% of intake, i.e., identical to acid detergent fiber digestibility because the diet did not contain a detectable amount of acid detergent lignin.
