説明

Experiments were conducted to investigate the physical characteristics of dried beet pulp (DBP) and extracted carbohydrates, and fermentation characteristics of DBP and extracted carbohydrates in an artificial rumen. Settling volume (SV) and water holding capacity (WHC) of DBP were the highest among commercial feedstuffs used in this experiment. SV of DBP and NDF from DBP (BP-NDF) increased slightly but ADF from DBP (BP-ADF) did not change in water and rumen liquid after 19 hours. SV values for DBP, BP-NDF and BP-ADF in rumen liquid were higher than those in water. Dry matter digestibility in vitro of BP-P was the highest among extracted carbohydrates. Pectin in DBP rapidly degraded, while BP-NDF did not degrade in 6 hours and BP-ADF did not degrade in 12 hours. Pectin in DBP rapidly changed to a large amount of acetic acid as compared with BP-NDF and BP-ADF, and propionic acid gradually increased after 8 hours. Fermentation characteristics of pectin in DBP were similar to those of pectin in apple and lemon.
