Extract

The inoculum represents one of the greatest sources of uncontrolled variation in digestibility estimates via in vitro rumen fermentation methods (Marten and Barnes 1980). Microbial activity of rumen inoculum may be influenced by animal and diet factors. The objective of this work was to evaluate the effects of the level of inclusion of concentrate in the diet of the donor animal on the measurement of the in vitro digestibility of hay.
