Perspective: Enteric methane mitigation and its impact on livestock hydrogen emissions
Journal of Dairy Science: In a hydrogen-based economy future, hydrogen leakage is becoming an environmental concern. Ruminants naturally produce small amounts of hydrogen, which is emitted in the environment along with other fermentation gases, such as the GHG methane and ...

Enteric methane emissions in grazing dairy systems. [PDF]
JDS Commun, 2023 Approximately 80% of agricultural CH4 comes from livestock systems, with 90% of that derived from enteric CH4 production by ruminants. Grazing systems are used worldwide to feed dairy cattle. Although quantifying enteric CH4 emissions in grazing systems has unique challenges, emerging technologies have made gaseous data collection more feasible and ...

Enteric Methane Emission from Pigs [PDF]
, 2011 The modern pig industry rely on relatively few feedstuffs mostly from cereals (corn, wheat, barley, oats, rye and rice), cereal co-products (different milling fractions, residues from biofuel and alcohol industries, etc.), cereal substitutes (tapioca, maniocca), legumes (peas, beans, lupins), protein concentrates (meal or cakes of soybean, rape ...

Physiological responses and adaptations to high methane production in Japanese Black cattle
Scientific Reports, 2022 In this study, using enteric methane emissions, we investigated the metabolic characteristics of Japanese Black cattle. Their methane emissions were measured at early (age 13 months), middle (20 months), and late fattening phases (28 months). Cattle with

Prediction of enteric methane emissions from cattle [PDF]
Global Change Biology, 2014 AbstractAgriculture has a key role in food production worldwide and it is a major component of the gross domestic product of several countries. Livestock production is essential for the generation of high quality protein foods and the delivery of foods in regions where animal products are the main food source.

Variability in Enteric Methane Emissions among Dairy Cows during Lactation. [PDF]
Animals (Basel), 2022 The aim of this study was to investigate variability in enteric CH4 emission rate and emissions per unit of milk across lactations among dairy cows on commercial farms in the UK. A total of 105,701 CH4 spot measurements were obtained from 2206 mostly Holstein-Friesian cows on 18 dairy farms using robotic milking stations.

Key Considerations for the Use of Seaweed to Reduce Enteric Methane Emissions From Cattle
Frontiers in Veterinary Science, 2020 Enteric methane emissions are the single largest source of direct greenhouse gas emissions (GHG) in beef and dairy value chains and a substantial contributor to anthropogenic methane emissions globally.

Feeding Strategies to Mitigate Enteric Methane Emission from Ruminants in Grassland Systems
Animals, 2022 Ruminants produce approximately 30% of total anthropogenic methane emissions globally. The objective of this manuscript was to review nutritional enteric methane abatement practices for ruminants that are applicable under grazing conditions.

Strategies to Mitigate Enteric Methane Emissions from Ruminant Animals
Journal of Microbiology and Biotechnology, 2022 Human activities account for approximately two-thirds of global methane emissions, wherein the livestock sector is the single massive methane emitter. Methane is a potent greenhouse gas of over 21 times the warming effect of carbon dioxide. In the rumen, methanogens produce methane as a by-product of anaerobic fermentation.

Maize silage for dairy cows: mitigation of methane emissions can be offset bij and use change [PDF]
, 2006 Increasing the digestibility of cattle rations by feeding grains and whole plant silages from maize have been identified as effective options to mitigate greenhouse gas emissions. The effect of ploughing grassland for maize crops have not been taken into
