Extract

The gas production (GP) technique, (e.g. Theodorou et al., 1994; Cone, 1994) is increasingly used as an indirect measure of substrate fermentability in the rumen. However, there are few data concerning the effects of making changes to the various integral steps of the GP procedure. This study investigated the effects of inoculum concentration and method of inoculation on the GP profile of high temperature dried grass (HTDG).
