Resumen
- Sugar beet pulp was digested in vitro using protease and pancreatin and the final residue (with no filtering) was fermented in vitro using three different ileal and caecal inocula (each one combining the digesta of three 70 d old rabbits), respectively. In vitro gas production was measured and modeled using single and dual pool models (logistic and Groot model). Dual pool logistic model minimized mean square error both for kinetics using both ileal and caecal inocula. The slopes of the regressions between observed and predicted values for each model were not different from 1, except for single pool Groot model, and intercepts did not differ from 0 only for single and dual pool logistics models. Fermentation of sugar beet pulp using ileal inocula produced 70% of the gas obtained using caecal inocula.Sugar beet pulp fermented twice faster with caecal than with ileal inocula (k: 0.031 vs. 0.016;P=0.010) using a single pool logistic model. Dual pool logistic model indicated a faster gas production rate at the beginning of fermentation for ileal compared to caecal inocula
