- ... A previous screening assay showed that, when used as additives in batch cultures of mixed ruminal microorganisms, both Rheum officinale root (RH) and Frangula alnus bark (FR) decreased methane production and caused changes in several fermentation parameters. The work reported here aimed to identify optimum dose levels of these plants to decrease methane production without causing adverse changes i ...

- ... Different plants, herbs and spices (158 samples) were tested in a screening trial to assess their potential to modify ruminal fermentation in vitro, in particular their effectiveness for decreasing methane production. In vitro incubations were carried in buffered rumen fluid at 39°C and after 24h of fermentation, gas production and pH were recorded, and gas and volatile fatty acids (VFA) were anal ...
