Estimation Methodologies for Enteric Methane Emission in Ruminants
2015As 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.

Effect of silage characteristics on enteric methane emission from ruminants.
CABI Reviews, 2019Abstract This review evaluates the effects of silage characteristics on enteric methane (CH 4 ) emission from ruminants by performing a meta-analysis. A total of 17 studies were selected from the literature, and the relationship between CH 4

Enteric Methane Emission and Reduction Strategies in Sheep
2017Climate 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.

Quantifying effects of grassland management on enteric methane emission
Animal Production Science, 2016Data on the effect of grassland management on the nutritional characteristics of fresh and conserved grass, and on enteric methane (CH4) emission in dairy cattle, are sparse. In the present study, an extant mechanistic model of enteric fermentation was evaluated against observations on the effect of grassland management on CH4 emission in three trials ...

Forage brassica: a feed to mitigate enteric methane emissions?
Animal Production Science, 2016A series of experiments was conducted in New Zealand to evaluate the potential of forage brassicas for mitigation of enteric methane emissions. Experiments involved sheep and cattle fed winter and summer varieties of brassica forage crops. In the sheep-feeding trials, it was demonstrated that several species of forage brassicas can result, to a varying

Enteric Methane Emission Under Different Feeding Systems
2015Methane is a potent greenhouse gas (GHG) which is responsible for global warming, and it is about 23 times more potent than carbon dioxide and is produced worldwide by biotic and anthropogenic activity. Increased industrialisation in the past few decades and an increase in global human population have increased the demand of food particularly of animal

Enteric methane emissions from German pigs [PDF]
, 2012 Methane emissions from enteric fermentation of pigs are object of emission reporting. Hitherto they were treated as part of the energy balance of pigs, in accordance with IPCC guidance documents. They were calculated from the gross energy intake rate and a constant methane conversion ratio. Meanwhile numerous experimental data on methane emissions from

Impact of ruminal pH on enteric methane emissions.
Journal of animal science, 2016The objective of this study was to determine the impact of ruminal pH on methane (CH4) emission from beef cattle. Ruminal pH and CH4 data were generated in 2 experiments using 16 beef heifers offered high-forage (55% barley silage) or high-grain (92% concentrate; DM basis) diets.

DREEM: model on enteric methane emissions in sheep farms
2016Ruminant livestock systems are significant sources of greenhouse gases. Herd mobility is known as a major adaptation strategy regarding seasonal availability of forage resources. The present study aims at quantifying enteric methane (CH4) emissions from French Mediterranean sheep farming systems, especially the use of diversified pastoral feed ...

Enteric methane emissions from German dairy cows
2012Up to now, the German agricultural emission inventory used a model for the assessment of methane emissions from enteric fermentation that combined an estimate of the energy and feed requirements as a function of performance parameters and diet composition, with the constant methane conversion rate provided in the IPCC guidelines.
