Description
Cumulative gas production from incubation of feedstuffs with rumen liquor or a fresh faecal suspension as inoculum in vitro together with crude nutrient composition can be used to predict organic matter digestibility and metabolizable energy content of ruminant feeds with high accuracy. In this study, prediction equations were derived for roughages using 110 samples with known in vivo digestibility. It can be demonstrated, that the accuracy of prediction of the gas production method is better compared with a pepsin-cellulase procedure and that the use of a faecal suspension as inoculum is a useful alternative when fresh rumen liquor is not available.
