Forage brassica: a feed to mitigate enteric methane emissions?

Animal Production Science, 2016
A 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 ...

Reducing Enteric Methane Emission Using Plant Secondary Metabolites

2015
Methane is produced from the anaerobic fermentation in ruminants as a pathway for the disposal of metabolic hydrogen produced during microbial metabolism. This methane is not only related to environmental problems but also is associated with energy losses to the tune of 8–12 % of ingested gross energy.

Quantifying effects of grassland management on enteric methane emission

Animal Production Science, 2016
Data 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 ...

Impact of ruminal pH on enteric methane emissions.

Journal of animal science, 2016
The 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

2016
Ruminant 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 ...

Prediction of enteric methane emission from beef cattle in Southeast Asia

Animal Science Journal, 2018
AbstractWe conducted a meta‐data analysis to develop prediction equations to estimate enteric methane (CH4) emission from beef cattle in Southeast Asia. The dataset was obtained from 25 studies, which included 332 individual observations on nutrient intakes, digestibilities, and CH4 emissions. Cattle were provided tropical forage or rice straw, with or

Enteric methane emissions from German dairy cows

2012
Up 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.

Mitigation of Enteric Methane Emissions from Indian Livestock

World Meteorological Organization (WMO) released the Greenhouse gas bulletin on 28th October 2024 which shows the atmospheric level of the greenhouse gases mainly naturally occurring ones are carbon dioxide, methane and nitrous oxide. These greenhouse gases are capable of absorbing a portion of the infrared radiations emitted by the earth (Ledley et al.

Enteric Methane Emission and Amelioration Strategies in Ruminants

Ruminants play a vital role in global food systems by converting forages from non-arable lands into high-quality animal protein. However, 2-12% of gross energy is lost as enteric methane (CH4), contributing nearly 6% of global anthropogenic greenhouse gas emissions.
