Zhang W, Li D, Liu L, Zang J, Duan Q, Yang W, Zhang L - J Anim Sci Biotechnol (2013)

Bottom Line: 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.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.

ABSTRACT
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 <0.01) when total dietary fiber increased but the digestibility of soluble dietary fiber and insoluble dietary fiber increased (P <0.01). The digestible energy and metabolizable energy content of diets decreased (P <0.01) as the total dietary fiber increased.

Figure 1: Relationship between the apparent total tract digestibility (ATTD) of totaldietary fiber (TDF) and the ATTD of soluble fiber (SDF) (a) and insoluble dietary fiber (IDF) (b) in sugar beet pulp fed to growing pigs (n = 30).

Mentions: The effect of TDF on the digestibility of fibrous components is shown in Table 3. The feed intake of diets tended to decrease (P =0.10) as the TDF increased. As expected, the intake of TDF, SDF and IDF and the excretion of TDF and IDF increased (P <0.01) as TDF increased, but the excretion of SDF was unaffected by TDF. The output of feces increased (P <0.01) as the TDF increased. The ATTD of TDF, SDF and IDF increased (P <0.01) when TDF increased. The relationship between ATTD of SDF, IDF and TDF is shown in Figure 1. There was a good relationship between ATTD of TDF and IDF (r2 = 0.93), but a poor relationship between the ATTD of TDF and SDF (r2 = 0.28).
