Nutritional management for enteric methane abatement: a review

Australian Journal of Experimental Agriculture, 2008
A variety of nutritional management strategies that reduce enteric methane (CH4) production are discussed. Strategies such as increasing the level of grain in the diet, inclusion of lipids and supplementation with ionophores (>24 ppm) are most likely to be implemented by farmers because there is a high probability that they reduce CH4 emissions in ...

Methane Emission from Enteric Fermentation: Methanogenesis and Fermentation

2015
Rumen fermentation of carbohydrates plays a fundamental role in ruminant metabolism as the main source of energy. Acetic, propionic and butyric acids (namely, volatile fatty acids, VFA) are the main products of the rumen fermentation of structural and nonstructural carbohydrates contained in the ruminant’s diet.

Dietary mitigation of enteric methane from cattle.

CABI Reviews, 2009
Abstract Enteric methane from ruminants accounts for about 11-17% of methane generated globally, or 17-30% of methane from human activity. Methane arises from the activity of methanogens in the rumen that use hydrogen to reduce carbon dioxide, thereby preventing the accumulation of reducing equivalents, which would otherwise impede ...

Effects of dilution on methane entering an SOFC anode

Journal of Power Sources, 2002
Abstract Methane and other hydrocarbons such as propane and butane are ideal fuels for SOFCs operating in portable devices for domestic or leisure use [J. Power Sources 71 (1998) 268]. This paper addresses the fuel entry conditions necessary for such devices.

Editing microbes to mitigate enteric methane emissions in livestock

World Journal of Microbiology and Biotechnology
Livestock production significantly contributes to greenhouse gas (GHG) emissions particularly methane (CH4) emissions thereby influencing climate change. To address this issue further, it is crucial to establish strategies that simultaneously increase ruminant productivity while minimizing GHG emissions, particularly from cattle, sheep, and goats ...

Feed-based approaches in enteric methane amelioration.

2015
Abstract Mitigation of methane (CH4) emissions from ruminants is necessary not only from the global warming point of view but also for saving dietary energy. Livestock being the significant contributors to the anthropogenic CH4 pool have remained the prime target of global research for the past two decades, in order to find suitable ...

Estimation Methodologies for Enteric Methane Emission in Ruminants

2015
As enteric methane emissions from ruminants contribute to feed inefficiency and global warming, methodologies to measure the enteric methane from either the individual ruminant or the herd are needed. Therefore, methane emission estimations in ruminants may provide insight into potential methane mitigation strategies.

Feed additives for methane mitigation: Recommendations for testing enteric methane-mitigating feed additives in ruminant studies [PDF]

Journal of Dairy Science
There is a need for rigorous and scientifically-based testing standards for existing and new enteric methane mitigation technologies, including antimethanogenic feed additives (AMFA). The current review provides guidelines for conducting and analyzing data from experiments with ruminants intended to test the antimethanogenic and production effects of ...

Enteric Methane Emission and Reduction Strategies in Sheep

2017
Climate change is associated with the anthropogenic emissions of greenhouse gases (GHGs) like carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) is widely evident throughout the world. CH4 is considered one of the major GHGs, 20 times more potent than CO2, contributing to 15–20% of total global GHG emission.

Prediction of enteric methane production in beef cattle

2016
Methane (CH4) is a greenhouse gas with an elevated global warming potential (GWP) equivalent to 28 times that of CO2. Also, production of enteric CH4 results in a 2 to 12% loss of the gross energy intake of cattle thus knowing the amount of CH4 released to the environment is important. The overall objective of this research was to evaluate the accuracy
