Development of a rumen fluid preservation technique and application to an in vitro dry matter digestibility assay
The objective of this study was to develop a rumen-fluid freezing and thawing protocol to be used with a two-stage in vitro dry matter digestibility (IVDMD) assay. Rumen fluid was collected on three different days (one week apart) from a domestic steer (Bos taurus) and preserved via freezing, freezing with 5% glycerol (GLY) or freezing with 5% glycerol plus a...
