Fermentation tubes for in vitro digestion of forages.


During in vitro digestion of forages by rumen microorganisms in polycarbonate centrifuge tubes, forage particles formed dense mats which were raised above the level of media by entrapped gas. This did not occur with polyethylene centrifuge tubes. In vitro organic matter digestion was higher in polyethylene than in poly-carbonate tubes. Vacuum infiltration… (More)
