The objective of this study was to investigate the effects of total dietary fiber level on nutrient digestibility and the
relationship between apparent total tract digestibility of total dietary fiber, and soluble dietary fiber, insoluble
dietary fiber and available energy. Sugar beet pulp was as the only fiber source. The experiment was designed as a
6 × 6 Latin square with an adaptation period of 7 d followed by a 5-d total collection of feces and urine. Feed
intake tended to decrease (P=0.10) as total dietary fiber level increased. The apparent total tract digestibility of dry
matter, crude protein and gross energy decreased (P
