Literature review of dietary manipulation to reduce methane emissions - CC0211

Methane is a potent greenhouse gas and fermentation processes in the digestive tracts of ruminant animals make a substantial contribution to total methane emission to the atmosphere. Little information is currently available about the modification or supplementation of ruminant diets in order to specifically reduce methane production per animal. In addition, since methane measurements using animals are time-consuming and require large-scale, specialised equipment, laboratory techniques for estimation of the methane-yielding potential of feeds and diets are urgently needed. This project reviewed the scientific literature on feed modification in order to identify future research priorities. The review concluded that research should focus on methods for enhancing the efficiency of rumen microbial growth. It was also recommended that an in vitro procedure, based on the volume of gas produced during the incubation of feeds in buffered rumen fluid, should be investigated as a laboratory technique.
