Description

The experiment evaluated bulk volume (ml/g meal) as a method of estimating forage quality. Samples of Lolium perenne (Lp) and Festuca arundinaea, and hay samples of Lp were collected at different stages of growth. Voluntary intakes of these forages by dairy cattle had been measured previously. Volumes of samples and volumes of cell-wall residues after 0, 6, 12, 24, and 48 hours in vitro digestion were determined.

Bulk Volume: A Parameter for Measuring Forage Quality and Its Influence on Voluntary Intake
