Animal performance
Due to rumen fermentation ruminants can convert fibrous plant material into high-quality proteins in de form of milk and meat. End products of rumen fermentation are volatile fatty acids (VFA) and high-quality microbial protein as the main resp. energy and protein source for animal performance.
Next to VFA and microbial protein, hydrogen and CO2 are produced which are converted into methane. Methane is an energy loss for the animal. Directing rumen fermentation in reducing this loss by reducing hydrogen production will increase animal performance and improve feed efficiency.
Methane
Production of methane accounts for 2-12 % of energy being lost for the animal (Johnson and Johnson, 1995). Methane is produced out of hydrogen and CO2 to reduce the hydrogen concentration in the rumen, which is necessary to keep rumen fermentation running.
The production of propionate will reduce the hydrogen concentration in rumen fermentation, opposite to acetate production that will increase the hydrogen concentration, in that way reducing the methane production and increase feed efficiency.
