To assess the ability of the collared peccary (Pecari tajacu) to digest dietary fiber, four adult male collared peccaries were randomly assigned to a 4 × 4 Latin square design to determine the effects of feeding non-traditional feed ingredients, taken from palm trees with different levels of dietary fiber, on intake and coefficient of total tract apparent digestibility (CTTAD) and mean retention time. Four experimental diets were provided ad libitum: corn and soybean meal-based control diet; corn and palm kernel cake-based diet; corn and peach palm byproduct-based diet; and hay, palm kernel cake, and peach palm byproductbased diet. The CTTAD of neutral detergent fiber and acid detergent fiber (ADF) were 0.80±0.09 and 0.61±0.21, respectively. Increasing levels of ADF in diets also linearly decreased the CTTAD of crude protein and gross energy, while increasing non-fiber carbohydrate linearly decreased the CTTAD of ADF. These results confirm the ability of peccaries to digest fiber. However, the intake of a high-moisture and lignified ingredient, as the peach palm byproduct, decreased feed intake of peccaries due to their relatively small forestomach volume, which in turn may decrease their performance when used for prolonged periods. Despite of that, collared peccary gain a significant benefit in digestibility of dietary fiber due to its complex stomach in which fermentation occurs
