Artificial Rumen Investigations. I. Variability of Dry Matter and Cellulose Digestibility and Production of Volatile Fatty Acids,

In vitro digestion of feedstuffs was carried out with diluted rumen liquor in glass bottles for 48 hr. Substrates used in the study were forages and a few mixed feeds. Most information was gathered on 39 samples of tall rescue (Festuca arundinacea), representing two to four cuttings (pasture height) per year of four genotypes over a 4-yr period.
