説明
To determine changes in the true density and specific gravity of the dietary particle mass and the bulk density of forages in the course of ruminal fermentation, seven kinds of hay were incubated in situ in the rumen of sheep given oat hay as their sole diet. The true density of the forage ranged from 1.6 to 1.8g/ml and showed no change with incubation time. The fractional specific gravity of the samples increased from around 0.7g/ml at the start of in cubation to about 1.3g/ml at 2h after incubation, and then stayed at nearly a constant level up to 96h of the incubation time. The bulk density of the forage particulates changed a little within 4h incubation, and thereafter decreased to about 70% of the original density after 24h of incubation without significant change for up to 96h of incubation. The degradation pattern of neutral detergent fiber was similar to the change in bulk density. A significant correlation was found between them (P<0.01). It was concluded that bulk density was related to the digestion of fibrous fraction through a change in the conformation of the forage particles. The true density and functional specific gravity, however, were not related.
