Greenhouse Gas Emissions from Ruminants

Ruminant livestock generates 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.

Portable Gas Analyzer for Greenhouse Gas Measurements

Gasmet portable FTIR analyzers like GT5000 Terra offers 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.

Case: Feeding willow to ruminants could reduce greenhouse gas and ammonia emissions

The GWCT Allerton Project has recently carried out experiments in collaboration with the University of Nottingham. The research builds on related research with the university in which they investigated the availability of nutritionally important minerals from grazed swards and tree leaves, and their uptake by weaned lambs.
