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.

Solutions to enteric methane abatement in Ireland

Irish Journal of Agricultural and Food Research, 2022
The efficiency of Ireland’s grass-based livestock systems can be attributed to high outputs, low production costs and a low carbon footprint relative to housed systems. Methane (CH4) is a potent greenhouse gas (GHG) of which enteric fermentation from livestock production is a key source, being directly responsible for 57% of Irish agricultural GHG ...

Invited review: Current enteric methane mitigation options

Journal of Dairy Science, 2022
El ganado rumiante es una fuente importante de metano antropogénico (CH4). Disminuir las emisiones de CH4 entérico de la producción de rumiantes es estratégico para limitar el aumento de la temperatura global a 1,5 °C para 2050. La investigación en el área de la mitigación entérica de CH4 ha crecido exponencialmente en las últimas 2 décadas, y se están

A Review of Enteric Methane Emission Measurement Techniques in Ruminants [PDF]

Animals, 2020
To identify relationships between animal, dietary and management factors and the resulting methane (CH4) emissions, and to identify potential mitigation strategies for CH4 production, it is vital to develop reliable and accurate CH4 measurement techniques.

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 ...

Short communication: Relationship of dry matter intake with enteric methane emission measured with the GreenFeed system in dairy cows receiving a diet without or with 3-nitrooxypropanol

Animal, 2020
The relationship between DM intake (DMI) and enteric methane emission is well established in ruminant animals but may depend on measurement technique (e.g. spot v. continuous gas sampling) and rumen environment (e.g. use of fermentation modifiers).

Estimation of the methane emission factor for the Italian Mediterranean buffalo [PDF]

, 2008
In order to contribute to the improvement of the national greenhouse gas emission inventory, this work aimed at estimating a country-specific enteric methane (CH4) emission factor for the Italian Mediterranean buffalo.

Relationship between residual feed intake and enteric methane emission in Nellore cattle

Revista Brasileira de Zootecnia, 2015
Feed intake and average daily gain (ADG) in Nellore cattle were determined to calculate residual feed intake in two performance tests: first during the growth phase (RFIgrowth) and then during a measurement of the methane emission phase (RFImet).

Predicting enteric methane production from cattle in the tropics

Animal, 2020
Accurate estimates of methane (CH4) production by cattle in different contexts are essential to developing mitigation strategies in different regions. We aimed to: (i) compile a database of CH4 emissions from Brazilian cattle studies, (ii) evaluate prediction precision and accuracy of extant proposed equations for cattle and (iii) develop specialized ...

Factors influencing dietary tannin inclusion in dairy diets: A review [PDF]

Journal of Applied Veterinary Sciences
T The objective of this paper was to evaluate factors affecting tannin dietary inclusion on enteric methane emission (CH4) and performance in dairy cows. Dairy production contributes to the greenhouse effect as it naturally emits enteric CH4.
