Fast Pool Kd/Hr

The fast pool rate (Kd) is derived from the maximum rate of degradation per hour of silage acids, sugar, rapidly degradable starch, and soluble fiber. Pell and Schofield (1993) published research on computerized gas production using individual vessel pressure sensors to relay gas pressure data. A more controlled system in conjunction with digestion kinetics analyzed by two‐pool logistic models (curve‐peeling) techniques (Schofield et al., 1994) further allowed gas fermentation to be divided into a “fast pool” (primarily B1‐starch and B2‐soluble fiber) and a “slow pool”(primarily B3‐insoluble available fiber).
