Ruminant livestock generate a significant proportion of anthropogenic GHG emissions, and thereby contribute to Climate Change. Ruminants such as cattle. sheep, goats and buffalo produce meat and milk through enteric fermentation – a digestive process in which microbes decompose and ferment food in the digestive tract or rumen. This process produces methane which is emitted via belching. The amount of methane produced is directly related to the type of food consumed and the level of intake, in addition to other factors such as animal size, growth rate, production level and environmental temperature. The loss of methane from ruminants also represents a loss of dietary energy, so initiatives to reduce emissions also represent an opportunity to improve the efficiency of livestock production.

Gasmet portable FTIR analyzers offer a powerful tool for researchers interested in the gases produced by ruminants. True multicomponent capability ensures that all gases of interest can be measured. The analyzers are also designed for field use, enabling on-site measurements with on-line results in demanding conditions without compromising on the quality of the analysis.
