Liquid and particulate passage rates and rumen volumes in lambs fed either fresh winter forage rape or fresh perennial ryegrass.

a The number of animals sampled. Values are means ± SEM.bP value for the difference between forage rape and perennial ryegrass.c Rumen liquid passage rate and rumen liquid volume were estimated using the method of Faichney [20] with Co-EDTA as the marker.d Rumen particulate passage rate was estimated using the method of Dhanoa et al. [21] with Cr-modanted fibre as the marker.Liquid and particulate passage rates and rumen volumes in lambs fed either fresh winter forage rape or fresh perennial ryegrass.
