In Vitro Gas Production Protocol
This video shows the laboratory analysis procedure for "In Vitro Gas Production". This method allows estimation of the digestibility and metabolizable energy (ME) content of ruminant feedstuffs. The amount of gas released during incubation of feedstuffs is closely related to digestibility and therefore the ruminant ME value.
