Extract

Food eaten by a ruminant firstly undergoes microbial fermentation within the rumen. Nutritionally important characteristics of the food are the rate and extent of fermentation of its carbohydrate fraction, which can both be estimated using the in vitro gas production technique. The single greatest source of uncontrolled variation in any in vitro rumen fermentation system is the rumen fluid; curves produced from gas production data were influenced significantly by the variation in microbial activity between days (Menke and Steingass, 1988; Beuvink et al, 1992). A more reliable measure of rumen fluid activity is needed. The objective of this study was to determine whether the frequency of sampling of rumen fluid affected the microbial activity and subsequent fermentation.
